Mazda CX-30 — Recalls, Reliability, Specs & VIN Decoder

I wondered if, after my first service visit on 11-12-25, the dealership put regular leaded gas instead of premium in it, because there was a noticeable difference in gas mileage and the engine started revving pretty high, in my opinion. It also seemed to have less power (which was my main reason foe thinking the wrong gas had been out in). And since then, it hasn't been the same.

One day after oil and filter change, engine LOW OIL LEVEL light illuminated on dash. Engine oil dipstick displays full oil level; no signs on oil leaks under the vehicle. Appears to be failed oil level sensor. Upon restarting the vehicle, LOW OIL LEVEL light is turned off. Intermittently returns after some time of driving. Have not observed light turning itself off without shutting down the vehicle.

At around 26,528 miles my 2022 CX-30 2.5s (not the turbo) developed a "Low Oil Pressure" warning while driving between 55-65mph on 07/06/2025. The car has had regular oil and filter changes about every 5K miles. The last oil and filter change was at 25,259 mileage on 05/25/2025. There aren't any visible oil leaks. I have read that this is a common problem for other Mazda CX-30 years 2021- 2022.

It has an oil consumption issue. Every 3,000-3,500 miles is will give the oil low light. It will be 1 quart low. The car takes 6 quarts of 5w30 synthetic oil and requires oil changes every 7,500-8,000 miles. I have had to put a quart in every time. I have taken it into the dealership and a third party oil service as well. The dealership has no idea why it keeps running through the oil. They state that it's a known issue but no recall.

The vehicle show "low engine oil" warning every 3k-4k miles although I change engine oil and filter regularly.

There have been 3 different ongoing issues. The car was ordered and delivered brand new in April 2022. At 4,000 miles and again at 12,000 mile is would display low oil and require 1 quart of oil. The dealership acknowledged that it has an oil consumption issue, unresolved. I have to bring it in every time it is low prior to its required oil change time/miles. At 19,742 miles the cars battery died. They replaced it an have no reason why it died. Every time I'm driving in the mountain pass the transmission will not advance above 3rd gear. The engine will whine and I have to put it into manual and move it to 4th and or 5th gear. When I coming down the other side of the mountain, I have the same issue with it only advancing to 3rd and not proceeding to 4th or 5th. Then when I reach the bottom and on flat road the message- safety system and deactivated. This last for apx 10 minutes. The dealership has no idea why it does it.

Passenger seat belt was stuck retracted and had to be replaced. Coolant temperature control valve failed and car ran cold. They have many cars with this issue but no recall was issued

"low oil" indicator came on after less than 5000 miles after oil change. Found oil to be 1 quart low. Scheduled oil changes are 10,000 miles apart, which suggests engine has defect which allows oil to be consumed within the engine. No signs of oil leakage.

On December 26, 2022, after running errands for an hour or so and parking outside in parking lots, I restarted the car and pulled out of a parking lot. 3 dashboard warning lights flashed, one after the other: Engine malfunction, have vehicle inspected; Dynamic stability control malfunction, have the vehicle inspected; Safety and driver support systems partially disabled, drive safely. Vehicle was stuck in high gear and would not shift to lower gear as I pulled into the driveway (fortunately I was close to home), forcing me to have to floor the gas pedal to go up the very slight driveway incline. Dealership thought they fixed the problem, exact same thing happened on 12/28/22 (same dashboard warnings, stuck in high gear) when we were on the highway. Car was barely able to make it up the exit ramp in heavy traffic, could easily have been rear-ended. We were able to get the vehicle home by driving in Manual. It would still not downshift, even in manual, but we managed to get home (about 20 miles) in high gear with slow acceleration. Once again dealership thought they fixed the problem. Exact same thing happened (same dashboard warnings, stuck in high gear) for the third time on 1/31/23. Fortunately I was close to home and was able to pull up the driveway by flooring the gas pedal once again. Car is currently at the dealership service center again. Vehicle has 8,156 miles.

I purchased a new 2022 Mazda CX-30 in early 2022. While driving home from out of state recently, a low oil warning light popped up on the dash. I immediately pulled over and checked the level to find only 2-3mm of coverage on the dipstick, well below the safe range. I topped the engine off with a full quart of oil. The vehicle only had 68xx miles on it when this happened.

I don't know, is 4:20 in the morning. Oh, is it work? I was sitting in my car and all of a sudden pop and I had ringing in my ear. According to Mazda, connect, I got some weird network. Error the network failure error some kind of engine failure. Error I don't know what happened. But I've been having a lot of network issues. I've had a lot of battery issues with the car. It's been in the shop at carry. Monster a number of times they've never taken care of the issue. I don't know I don't know what to do. I won't even driven

On April 15th, 2025, my 2022 Mazda CX-30 experienced a sudden malfunction while I was driving. Despite having the automatic emergency braking system and forward collision warning, the car failed to slow down or alert me before I hit another vehicle during a pile-up. Right after the collision, my dashboard lit up with multiple error messages about the forward collision system, brake system, and sensor malfunctions. I had the car towed to the dealership, where a full diagnostic scan was performed. It revealed multiple hard fault codes, including U0415 (Invalid Data Received from ABS Control Module), which I later found was listed in a recent Mazda recall (23V-487) affecting my exact safety system—but Mazda told me my VIN was not included. The vehicle was inspected by a certified Mazda dealership. Mazda has refused to take full responsibility despite the safety system failing and the car still being under warranty. My safety was put at direct risk because the brake system did not function when it should have, causing a wreck that could have been avoided.

2025 Mazda CX-30 experienced a sudden complete loss of power while driving at highway speed with no prior warning lights or indications of malfunction. Immediately before shutdown, steering became extremely stiff due to loss of power steering assist. Vehicle was steered towards the shoulder during highway speed of 65mph and was electrically inoperable while rolling, this includes the loss of hazards, power steering and electronic brake lock engagement.

The vehicle has major electrical issues. The ABS and all over driver safety options would shut off for days at a time. I had purchased this cx30 as new on January 02, 2026. It totally died and wouldn't start on February 03, 2026. It had to ve towed by mazda roadside assistance to Towne Mazda dealer in Orchard Park NY. It is now March 12, 2026 and the dealer has had my vehicle for over a month. They put a new wiring harness in it ans other components. Very frustrating.

The contact owns a 2025 Mazda CX-30. The contact stated that the key fob had a slight dent, and after dropping the key fob, the key fob fractured into several pieces. The contact was unable to lock and unlock the vehicle using the key fob. The dealer was contacted and informed of the failure. The dealer advised the contact to purchase a new key fob. The key fob was not replaced. The manufacturer was made aware of the failure. The contact’s spouse's key fob had a similar failure, even though there was no dent in the key fob before the failure. The contact saw many online forums with the same defect. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was unknown.

I have been having repeated issues with the doors not autolocking, liftgate functionality, rear seat sensor, and random (collision?) warnings/sensors - among other settings that keep coming undone (audio options, etc) since the purchase of this car that I have been diligently notating/timestamping- i have close to 200 occurences so far. Just submitting another report to let you know it is STILL happening and IS NOT user error.

It seems like the computer has defaulted to receive the lowest possible gas mileage- if this is somehow communicating with the fuel system- its definitely affecting how much mileage I could be getting and robbing me of up to 100 miles per tank.

At 1833 yesterday evening, the doors did not autolock.

It 1833 the doors did not autolock

Iactive sensor indicated there was a/n (obstruction) or something preventing iactive from working (i dont remember what it said)? I dont remember- but either way- i find it distracting. It could not be turned off and was flashing repeatedly- telling me to drive safely ironically making me feel like I had to read it, in inclement weather, and take my eyes off the road.

The contact owned a 2021 Mazda CX-30. The contact stated that her husband was driving 60 mph on cruise control and while approaching a traffic light he depressed the brake pedal but failed to deactivate the cruise control and stop the vehicle. The contact stated no warning light was illuminated. The driver steered to the right and crashed into another vehicle. The contact stated all the air bags did deploy. The driver sustained leisure on his back and both legs due to the air bag deployment. The contact sustained leisure on her head, her nose, her left ribs, hips, and both legs due to the air bag deployment. The contact stated they both sought medical attention at a near hospital. The contact did not know in detail the injuries of the other individuals but did know both individuals sought medical attention. A police report was filed. The vehicle was not drivable. The insurance company deemed the vehicle a total loss. The vehicle was towed to an unknown location. A dealer was not contacted. The manufacturer had not been informed of the failure. The failure mileage was approximately 14,000.

While driving normally at highway speed on I-880 South, the braking system failed to decelerate the vehicle. When the brake pedal was pressed firmly, there was no normal slowing—only a sliding sensation, as if the wheels locked and the car moved forward on ice. This led to a collision with a stopped vehicle ahead. The following day, the Mazda App displayed a red alert message: “Brake system malfunction. Braking effectiveness may be decreased.” The vehicle’s airbags deployed very forcefully, causing bruising to both driver and passenger, even though the impact was not severe. Three days before the incident, the vehicle had a scheduled maintenance and recall service at a Mazda dealer, including a brake inspection and air-bag recall repair. The vehicle was declared a total loss by the insurance company and is currently stored at Copart Hayward, CA. The problem has not been inspected by Mazda yet, but a formal safety review is requested. The issue posed serious safety risks due to total loss of braking control and unexpected air-bag deployment.

While driving down the road a vehicle in front of me braked to stop for a bus loading kids, as I stepped on the brakes nothing happened and the vehicle surged forward. After the accident I viewed the vehicles onboard system status and it had logged several errors including errors to the activsense driver assist control. I used the vehicle’s emergency assist button and contacted 911, and reported the incident to ride share and contact my spouse. Police report lists the wrong time and vehicle but does have the correct vin number

This is already related to Mazda's recall #23V-275 BRAKE PEDAL TRAVEL CONCERN. My car was already involved in crash which I firmly believe that it was related to the brake pedal issue since the brakes didn't hold off the car and the brake assist system was never activated during the accident. Mazda is claiming that my ABS system serial number is a good part, and their dealership claimed that the problem couldn't be reproduced after they held the car for 11 days! I made several attempts to contact Mazda USA but I am not getting tractions for weeks.

On April 15th, 2025, my 2022 Mazda CX-30 experienced a sudden malfunction while I was driving.

My safety was put at direct risk because the brake system did not function when it should have, causing a wreck that could have been avoided.

The accident occurred on the afternoon of Tuesday, November 14, which I reported to Enterprise, City of Falls Church, on the morning of November 15. Additionally, I provided to Enterprise email links to the many reports about breaking problems about the CX30 2021, 2022, and 2023 MAZA models and the reasons for their recall for repair. Here are the details about what happened. As I was trying to put the car in reverse from a standing position, the car, instead, lurched forward at great speed headed toward the Sun Trust bank. I had to use super-human strength to the brake pedal on the car to force it into a standing position. The damage to the car is due to scrapping some bark off one of the trees that separates the Sun Trust Bank property from the CapitalOne bank property where my car was parked.

On March 9, 2023 - car brakes failed at a red light and vehicle collided with an oncoming car coming from the adjacent direction. Vehicle proceeded not to brake for an additional 30 sec minum at which the brakes finally engaged. There was no braking alert - the smart braking system did not engage and there was Forward Collision warning. It is available for inspection upon request. My safety and the safety of oncoming passengers were at risk which could have been fatal Insurance representatives have not yet inspected. Absolutely no warning lots engaged.

On multiple occasions while driving in rain/snow/ice, the vehicle will initially throw an "i-ACTIVESENSE Partially Disabled Due to Camera Malfunction" error. This initially disables adaptive cruise control, lane keeping, blind spot detection, etc. This error immediately then cascades to throw a "Dynamic Stability Control Malfunction" error as well as an "ABS Malfunction" error, suggesting that both dynamic stability control and ABS are disabled. This issue has occurred roughly 50% of the time it rains/snows, and usually persists for 1-2 days even after fully clearing the windshield where the front camera system is located. This has caused me to have to drive the vehicle several times now in the rain and snow without ABS and dynamic stability control active -- this is a serious safety issue. It is understandable for a front camera malfunction to disable sensing features (like lane keeping), but this should not disable necessary safety features such as ABS and stability control. It is clear that there is a cascading sensor malfunction in this vehicle (possibly related to an earlier similar recall in 2024 models), that causes serious safety concerns.

The vehicle has major electrical issues. The ABS and all over driver safety options would shut off for days at a time. I had purchased this cx30 as new on January 02, 2026. It totally died and wouldn't start on February 03, 2026. It had to ve towed by mazda roadside assistance to Towne Mazda dealer in Orchard Park NY. It is now March 12, 2026 and the dealer has had my vehicle for over a month. They put a new wiring harness in it ans other components. Very frustrating.

Warning sensors activate randomly- of oncoming vehicles- in my opinion for no reason. Enough space between cars. Normal speeds, etc. Warning sensor to engage Brakes activate without sufficient reason. More than enough space between cars, normal speeds. Occasionally, it feels as if cruise control has taken over and slows the car down (not braking exactly, but controlling the speed by decreasing it). Acceleration also seems to randomly be controlled in the same manner.

While driving normally at highway speed on I-880 South, the braking system failed to decelerate the vehicle. When the brake pedal was pressed firmly, there was no normal slowing—only a sliding sensation, as if the wheels locked and the car moved forward on ice.

The contact rented a 2024 Mazda CX-30. The contact stated that while driving at highway speeds, an "i-ACTIVSENSE Partially Disabled Front Radar Malfunction" warning message appeared on the instrument panel. The contact attempted to exit the highway; however, the vehicle failed to stop upon depression of the brake pedal. The contact continued to pump the brakes and even engaged the emergency brakes, but the vehicle failed to stop. Due to the failure, the contact crashed into the vehicle in front of her as the "Vehicle System Malfunction, Have the Vehicle Inspected" warning message appeared on the instrument panel. The air bags did not deploy upon impact. The contact later sought medical attention for pain in her back; the other driver sustained injuries; however, the injuries are unknown as she did not seek medical attention from the paramedics that arrived at the scene. A police report was filed. The vehicle was towed from the scene to an independent mechanic, where it remained in their possession. Neither the dealer nor the manufacturer had yet been notified of the failure. The vehicle was not repaired. The failure mileage was 38.377.

The contact owned 2021 Mazda CX-30. The contact stated while attempting to park the vehicle in the parking garage at her workplace, the contact reversed and then straightened the steering wheel; however, after shifting to drive and attempting to drive 6-10 feet forward into the parking space, the vehicle unintendedly accelerated and crashed into a pillar before coming to a stop. The contact stated that the engine had revved up, and the vehicle made an abnormally loud sound before the vehicle unintendedly accelerated. The contact stated that the brake pedal was depressed but the vehicle failed to respond, and the vehicle failed to stop as needed. There was no warning light illuminated. The contact stated that the air bags deployed as intended; however, a warning light indicating an air bag malfunction illuminated afterwards. The contact stated that the front driver's side and knee air bags had deployed as designed. The contact sustained pain and bruises on the left side of the chest, on the upper part of the left breast, on the left leg, and on the right wrist and right arm. The vehicle automatically called 9-1-1 for Emergency Assistance, but the contact declined to receive medical assistance. The contact was able to walk away from the scene. No Police report was filed. The contact was unsure whether there was any property damage. The vehicle was towed from the scene and totaled by the Insurance Company. The contact stated that the failure had occurred once before while driving at approximately 60-65 MPH, and the vehicle unintendedly accelerated with an abnormal sound coming from the vehicle, but the contact was able to depress the brake pedal and regained control of the vehicle. The dealer and the manufacturer were not yet notified of the failure. The failure mileage was approximately 31,000.

The contact owns a 2025 Mazda CX-30. The contact stated that while driving at approximately 2 mph into his garage, his right foot had slipped between the brake pedal and the accelerator pedal, and he was unable to get his foot out from under the pedals. The contact stated that the front end of his vehicle crashed into his garage wall. The contact stated that there was some damage to the front grill and the hood of the vehicle. The contact stated that he had not taken the vehicle to a dealer or collision shop. The contact had called the manufacturer and was advised that there was no action that could be taken to adjust the distance separating the brake pedal from the accelerator pedal. The contact stated that his foot had been trapped on two other occasions. The failure mileage was approximately 700.

My brakes failed at a stop light. I was waiting at a red light waiting to get on the freeway . Brake was completely pressed, when my car started rolling forward. I kept trying to apply more force to brakes but was unable to stop the vehicle until it rolled into the car in front of me. I then had my car towed to Mazda and was told my accident was a result of human error. Inspection was done and no results were found. If my brakes had failed at any other moment my accident could have been deadly. There is a brake recall for my year make and model but my vin number is not yet apart of that recall. My car was barely a year since purchase I am the first owner .

I have been the owner of a 2023 Mazda CX-30 since July 2023. On [XXX], 2023, I received automated warnings on the dashboard and through the Mazda App stating, "ActiveSense system malfunction. ActiveSense advanced safety and driver support system may not operate correctly." The service department at the dealership where I purchased the car explained that the sensors had overheated due to the hot weather. Unfortunately, a similar warning appeared on the dashboard on [XXX], and this time it resulted in damage to the car. On that day at 13:33, while maneuvering into a parking spot in the parking garage with my foot on the brake pedal, the car suddenly and rapidly accelerated and collided with a concrete post. Fortunately, I am unharmed but shaken, and the front of the car sustained damage. Immediately after the incident, I contacted the service department, explained the situation, and requested an emergency service to assess the car. The service department conducted checks on the brakes and suspension, performing a full-circle inspection. Their report stated, "Could not find any evidence to support the customer's claim." The service advisor expressed disbelief in the issue I described, stating he had not heard of such problems before. Contrary to the service advisor's disbelief, records on NHTSA.gov reveal numerous instances of sudden unintended acceleration while pushing on brakes for Mazda CX cars (CX5, CX30, CX50). These instances have occurred and have been reported nationally/across numerous states in the USA. I am urging Mazda to thoroughly investigate all reported complaints, issue recalls for affected cars, and enhance their safety features. As of now, there have been no reported fatalities, and it is crucial for Mazda to take proactive measures in investigating and addressing our claims to prevent any potential harm caused by errors in the ActiveSense system.

car was put on rear and it leaped forward and crashed and caused property damage and driver was shocked. faulty system, Collison system failure, reverse gear failure. on two different occasions car initiated warning like misuse of pedals when car was rolling down which was errored warning. false lane assist warnings.

Although im confident in my own driving skills, it concerns me that the blind spots are so bad that it is NECESSARY to use the blind spot warning system and reverse/back up camera.

I have noticed over 30 things wrong with this car. Including but not limited to- the FIRST THINGS I mentioned to the dealership there seems to be apull to the right (suspension/alignment). The car randomly starts driving or feeling 'jerky" as if cruise control has taken over - 'phantom braking' is a term I came across that sounds accurate to me. And now, after having the vehicle for almost 30 days- there is significantly less mpg.received. 300 first tank vs about 250 this current tank.

I was driving down the Highway and the sun roof just exploded send shards of glass everywhere and nothing had hit it or anything. It just exploded. When I got to the dealer the person ahead of me had the exact same thing and we compared pictures. It was scary, dangerous and really loud when it happened.

The contact owns a 2023 Mazda CX-30. The contact stated while driving at undisclosed speeds in the rain, the driver’s side windshield wiper failed to clear the water on the windshield. The vehicle was taken to the local dealer, on several occasions, where it was diagnosed that the wiper blades and wiper arms needed to be replaced. The vehicle was repaired, but the failure recurred. The manufacturer was contacted, and the contact was referred to the local dealer for assistance. The failure mileage was approximately 30,000.

Immediately after leasing my vehicle (2023 Mazda CX 30 Turbo) & leaving the dealer (no test drive), I noticed the windshield had a distorted view to it with a wavy/orange peel look covering the entire windshield. When looking at the cars in front of you, road signs, road lines, buildings they all had a orange peel/wavy distorted look to them. After 20 minutes of driving it starts to make you feel dizzy, sick, distorts vision & is very annoying. I went online & found a TSB from Mazda for the 20-22 models for the same problem. I reported my windshield to the dealership who verified, took photos & replaced the windshield through Mazda warranty. HOWEVER, the second windshield is worse than the first. The dealer really didn't know what to say so I have given up. The car is brand new and the driving back & forth to the dealer (in another city) in the first month has put way too many miles & took a lot of time (I was there 3 weekends in August for this issue). I did more investigating & have found many Mazda CX 30 Turbo owners with the exact same complaint, some have had the windshield replaced multiple times & still have the same issue (which is why I don't want to go through the aggravation of getting another one done just to end up with the same/worse situation like I'm in now with the new one). A quick google search & you will find many complaints. There is obviously something wrong with the glass Mazda is using for the CX 30 models. I had a CX 5 loaner from the dealer & it was fine. I now only drive my new car basically to work & home. 20 minutes in and you start to feel dizzy, which is not a good feeling. I hope someone can look into this further so I & other CX 30 owners can get a permanent solution for this or the next 3 years are going to be miserable. The car is brand new & I hate driving it.

The windshield is wavy. I don't know if it is the shape of the window, but very hard to see it of. Several owners have the same problem in online forums. Can't drive my vehicle long distances because I get extreme headaches, and visibility is decreased.

I took delivery of a 2022 Mazda CX-30 recently, and noticed that the windshield was very distorted. Moving my head caused the image to shift in unexpected ways. The windshield was noticeably wavy and caused double vision. The dealer replaced the windshield, but the replacement is also noticeably wavy, with an almost orange peel look through the new windshield. The new windshield also distorts the active driving display as well, which was not apparent on the original. When I complained about the replacement, the dealer's service manager said that what I am experiencing is "normal", and that "all CX-30s are this way", even though he previously admitted that he had never seen it before, and that the CX-50 he was driving did not have this issue at all. I see that Mazda has a technical service bulletin for this problem for older model CX-30s. https://static.nhtsa.gov/odi/tsbs/2021/MC-10203731-0001.pdf It seems that Mazda has not fixed this issue, as it is very noticeable on my 2022 model CX-30. I can understand that glass will be refractive under extreme angles, but this is when I'm looking directly ahead. If I move my head at all, the image bends and distorts. Unfortunately, the issue does not lend itself well to photos, as it is most noticeable when you have both eyes open (two eyes see through the glass at slightly different angles and points on the glass). If I close one eye, I no longer get double vision, but I doubt that's the safest way to drive.

I have noticed the windshield is distorted and from reports all over the Internet that seems to be an issue with 20-22 mazda cx-30’s and I don’t think Mazda is going to replace it. It causes me to get fatigued, and a little dizzy at times during long distance driving.

I picked up my certified pre owned CX-30 just 2 days ago and noticed the windshield appears distorted or wavy which results in eye strain and headaches. This seems to occur in the left side of the windshield. It is difficult to focus for long periods of time. I asked another person to drive the car and they confirmed it nearly instantly. I recently learned this is a known issue with the vehicle.

Was driving on interstate, during the afternoon, not close to any other traffic ahead. It was neither raining nor particularly windy. I heard a very loud “explosion” sound, like a gunshot. I pulled over and my sunroof is bowed OUTWARD a little, and missing a big section of glass. There is no rock or debris laying on the interior screen, and the sunroof is NOT concave like from an impact. It is clearly blown upward.

While driving normally at highway speed on I-880 South, the braking system failed to decelerate the vehicle. When the brake pedal was pressed firmly, there was no normal slowing—only a sliding sensation, as if the wheels locked and the car moved forward on ice. This led to a collision with a stopped vehicle ahead. The following day, the Mazda App displayed a red alert message: “Brake system malfunction.

Three days before the incident, the vehicle had a scheduled maintenance and recall service at a Mazda dealer, including a brake inspection and air-bag recall repair. The vehicle was declared a total loss by the insurance company and is currently stored at Copart Hayward, CA. The problem has not been inspected by Mazda yet, but a formal safety review is requested. The issue posed serious safety risks due to total loss of braking control and unexpected air-bag deployment.

I was involved in a traffic accident on 6/29/23 involving myself and my [xx] year old son, both in the front seat. We were struck in the back by one vehicle, spun out of control, hit another vehicle on the passenger side where my son was sitting and spun out of control again. Driver side did not strike anything and side airbags deployed (both front seat and back seat), passenger side airbags never deployed. My son's safety was put at risk as the damage was extensive and the car was totaled. He suffered two fractures in his shoulder and a broken clavicle. The problem has not been confirmed by the dealer. The vehicle has been inspected by my insurance carrier, Progressive. There were no warning lights, and no lights confirming that the airbag was turned off while my son was sitting in the passenger side. “INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).”

The contact rented a 2024 Mazda CX-30. The contact stated that while driving at highway speeds, an "i-ACTIVSENSE Partially Disabled Front Radar Malfunction" warning message appeared on the instrument panel. The contact attempted to exit the highway; however, the vehicle failed to stop upon depression of the brake pedal.

I don't know, is 4:20 in the morning. Oh, is it work? I was sitting in my car and all of a sudden pop and I had ringing in my ear. According to Mazda, connect, I got some weird network. Error the network failure error some kind of engine failure. Error I don't know what happened. But I've been having a lot of network issues. I've had a lot of battery issues with the car. It's been in the shop at carry. Monster a number of times they've never taken care of the issue. I don't know I don't know what to do. I won't even driven

I have received a recall notice back in June 5th. I tried to reach my dealer (Douglas Mazda) couple of times but they are not fixing it. As it has been announced that, it is not available. The vehicle is under warranty. PLease suggest me what steps I should take? As it is not not safe drive in any highway.

On [XXX] autoNation Mazda Arapahoe in Colorado sold me a car for my sign at 2024 CX 30 premium. They said there was an open recall that they needed to fix and we’re keeping the car overnight on June 6, 2025. They deliver the vehicle to my son around noon and around 6 PM on June 6. They contacted my son and said they shouldn’t have sold the vehicle to him and needed the vehicle back. This is my son‘s first vehicle and it’s not a good experience and the dealership should never have sold that car to us knowing that there was not a fix. They were well aware of this on May 29.

Wife was driving 2024 Mazda CX-30 with (bought demo from dealer in February with 2500 miles on it and now 4006 miles) daughter ([XXX]) in passenger seat. Airbag deployed with no warning or malfunction lights or alerts prior. Knocked my daughter across the vehicle, startled and traumatized both of them. They were able to safely pull into a shopping center parking lot. Got vehicle towed to the dealer, John Kennedy Mazda in Pottstown PA. Called police--have report and pictures to document. Wife also has videos and pictures. The dealer provided us a loaner vehicle. Next day the service manager, Gary Daniels calls. I ask if he has ever seen this before. "I think I know what caused it. There was a bubble in the right front passenger tire." I responded that I saw how this was going and told him I will be in touch. Dealer not covering it under warranty and said "call our 800 # and your insurance." Called 800 line and talked to Giselle, our case manager who said this would be "escalated" and we would hear back in 48 hours. Of course, we did not hear back. Finally, after 2 voicemails and contacting Mazda USA via chat, they call back and say call insurance, it will not be covered under warranty. When I ask for what the escalation was, the rep said "well the dealer said there was a bubble in the tire." Complete runaround. I go to the dealer to return the loaner car and they provide me a watered down and inaccurate report saying the bubble was existing. Insurance has provided an estimate to repair the car for just under $5000. I am not comfortable having the dealer repair the car or any family member drive that car once repaired. Airbag malfunction warning lights everywhere post deployment. No warnings before and ridiculous claim that a bubble in a tire could cause an airbag to deploy. Considering the repair but also legal action as zero empathy by the dealer and no accountability of fixing what seems to be a similar issue in New Hampshire with the same model car 2 years ago.

The air bag warning system shows "passenger air-bags not engaged" If involved in any accident that requires passenger air-bags to inflate, they will not. Causing serious to deadly consequences. January 28 2025 the Mazda service department had our vehicle to recalibrating the system. Checking the problem after the service still show the same problem. Another Mazda CX-30 was brought over, and the same problem existed. Also a Mazda CX-5 was tested and no problem was found. This was the second time this problem has been returned to the Mazda Dealership. This problem has existed since purchasing this vehicle.

I am writing to report a serious safety issue with my vehicle, which resulted in a crash. While driving, I suddenly heard a loud sound, followed by an unexpected and uncontrollable shift of the steering wheel to the right. At the same time, the car unexpectedly accelerated, causing me to lose control and crash into a parked vehicle. The airbags deployed, and my car was totaled as a result of the collision. There were no obstructions on the road at the time of the incident, and the vehicle veered to the right without any prior warning. The car was purchased recently, with only approximately 3,000 miles on it and had been driven for just two months before this occurred. There were no warning signals or indications of any issues before the incident, and the car was in nearly new condition. This sudden loss of control, especially with such low mileage, strongly suggests that there is a serious mechanical issue, likely with the steering or related systems. I am requesting that Mazda thoroughly investigate this matter, as it clearly poses a significant safety risk. The vehicle has been towed to AAA Insurance for inspection, and I would appreciate your immediate attention to this claim. Please let me know the next steps in the investigation process. Thank you for your prompt attention to this critical safety concern.

The contact owned 2021 Mazda CX-30. The contact stated while attempting to park the vehicle in the parking garage at her workplace, the contact reversed and then straightened the steering wheel; however, after shifting to drive and attempting to drive 6-10 feet forward into the parking space, the vehicle unintendedly accelerated and crashed into a pillar before coming to a stop. The contact stated that the engine had revved up, and the vehicle made an abnormally loud sound before the vehicle unintendedly accelerated. The contact stated that the brake pedal was depressed but the vehicle failed to respond, and the vehicle failed to stop as needed. There was no warning light illuminated.

The vehicle automatically called 9-1-1 for Emergency Assistance, but the contact declined to receive medical assistance. The contact was able to walk away from the scene. No Police report was filed. The contact was unsure whether there was any property damage. The vehicle was towed from the scene and totaled by the Insurance Company. The contact stated that the failure had occurred once before while driving at approximately 60-65 MPH, and the vehicle unintendedly accelerated with an abnormal sound coming from the vehicle, but the contact was able to depress the brake pedal and regained control of the vehicle. The dealer and the manufacturer were not yet notified of the failure. The failure mileage was approximately 31,000.

The contact owns a 2021 Mazda CX-30. The contact stated while driving at an unknown speed, the vehicle accelerated independently and hit a brick pillar. The contact stated no warning light was illuminated. The air bags did not deploy. The contact sustained injuries on her neck, back, and also had headaches. The contact did seek medical attention at the emergency room. A police report was filed. The vehicle was not drivable. The vehicle was towed.

The contact owns a 2021 Mazda CX-30. The contact stated that while driving at an undisclosed speed, the accelerator pedal was slightly depressed; however, the vehicle speed increased significantly independently. The contact stated that the failure occurred as the contact arrived at the contact's residence and was attempting to park the vehicle. The contact stated that the brake pedal was depressed; however the vehicle failed to stop, and the vehicle was uncontrollable. The contact stated that the vehicle crashed into the contact’s apartment building. The contact stated that the building siding and steps were damaged due to the failure. The contact was not injured; however the failure had caused serious anxiety issues for the contact. The vehicle was towed to a local tow yard. In addition, the contact stated that the vehicle was towed to the dealer two times prior to the failure because, when attempting to start the vehicle, the vehicle failed to start. The contact was informed that the vehicle's not starting was the result of a faulty battery, and the battery was replaced. In addition, the contact stated that the independent acceleration failure had occurred the day before the crash occurred; however the contact was planning to take the vehicle to the dealer the following day. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 47,000.

Warning sensors activate randomly- of oncoming vehicles- in my opinion for no reason. Enough space between cars. Normal speeds, etc. Warning sensor to engage Brakes activate without sufficient reason. More than enough space between cars, normal speeds. Occasionally, it feels as if cruise control has taken over and slows the car down (not braking exactly, but controlling the speed by decreasing it). Acceleration also seems to randomly be controlled in the same manner.

I was sold this 2024 Mazda cx30 from Ken ganley kia located in mentor Ohio (44060) the vehicle started showing major electrical issues. when they occur I have no control of the functions of anything in the cabin (infotainment, heat/air, braking system,) just to name a few. My wife and I were assured we were purchasing a good safe and reliable used vehicle. I feel this vehicle is extremely unsafe and unpredictable and ken ganley kia of mentor refuse to take this unsafe vehicle back or even pay for the repairs. I am utterly disappointed such a big name in the auto industry could turn there back on a customer not only that let a young family pull off in a unpredictable electrical nightmare of a vehicle and refuse to stand by it.

While coasting slowly through a parking lot at approximately 5-8mph I tapped the brake to slow further while making a tight turn and to safely pass a vehicle also turning towards me. This caused the car to lurch and accelerate as though my foot was on the gas pedal, but it wasn't. I had to step hard on the brake to bring it under control.

It happened twice already when I step on the break pedal the car goes accelerated feels like you step on the gas pedal that is the problem the first incident I stopped and parked next to the gate because I need to put the code of the gate to open then when I come back to my car and step on the break to release the transmission from P parking ️ then the car goes accelerate too fast almost hit the gate good thing I release the break pedal then hit again or step again the break pedal. The second time I was with my wife she’s parking backward then the car goes accelerated backward. She just stepped on the break pedal. And if we’re driving in the freeway if we break it didn’t stop right away it will still slide for how many meters

While I was driving on I-90, I lost control of the acceleration of my vehicle. The vehicle was towed and has been diagnosed with a failed transmission! The car would not accelerate or it would accelerate in bursts or rapidly slow down. I was able to pull over and the car failed to move at all after. My safety and others was put at risk as I lost the ability to control the speed of the vehicle on a road where the speed limit is 65mph in traffic around me. When the problem began no lights illuminated, until ~30 seconds in the yellow engine failure light illuminated and then the yellow transmission failure light illuminated. The car was brought to a dealership for inspection and they diagnosed it as a transmission failure. This is unacceptable for such a young vehicle (2021). It should be noted that the car manufacturer immediately approved the replacement the same day it was diagnosed (dealership said it usually takes 48 hours), but the part is back-ordered for months (probably because they know this is happening and trying to cover it up).

I had both the left front and right front CV axles fail. My car only has 11.5k miles on. I first heard the clunking noise at 11k miles, went right to the dealer and had them watch me recreate the noise and they determined the axles needed to be replaced. This is incredible dangerous as the CV axle could have been completely disconnected from the wheel assembly leaving my car useless and uncontrollable.

I purchased a brand new 2023 Mazda CX – 30 from Cooley Mazda on September 27, 2023. I was excited to upgrade from my 2011 Mazda 3, however I have had issues early on. On June 7, 2024, I brought my 2023 Mazda CX – 30 in for diagnostic testing for front end noise and a shifting issue. I went out for a drive with the Technician and was told the noise I was hearing was from the weight of the car on the suspension, I disagreed. The Technician also experienced the shifting issue I spoke of, and I was told that the car needed to learn my driving technique, again I disagreed. At this point the vehicle only had 4014 miles on it. On July 25, 2024, I brought the vehicle in for its 1st oil change and tire rotation, as well as for the same noise and shifting issues. This time they found an issue with the front driver side front wheel bearing. They did not have the part in stock, so I had to wait for a call to schedule to come back once the part came in. Again, they claimed there was no shifting issue with the vehicle. At this point the vehicle only had 5079 miles on it. On August 7, 2024, I brought the vehicle in for replacement of the front driver side front wheel bearing. On my drive home I heard the same noise I brought it in for repair for. At this point the vehicle only had 5468 miles on it. On September 4, 2024, I brought the vehicle in for a NYS Inspection and for diagnostic testing on the noise and shifting issues, again they took the car out, did not experience the issue, but put it on the lift and did some testing which determined the car needs a new rear differential. At this point the vehicle only had 6219 miles on it. The rear differential was replaced and the vehicle still has shifting issues. It hesitates, sometimes doesn't advance when the gas pedal is pressed. The vehicle also hesitates at 38-40 and 58-60 mph while just holding your foot steady on the gas pedal.

On December 26, 2022, after running errands for an hour or so and parking outside in parking lots, I restarted the car and pulled out of a parking lot. 3 dashboard warning lights flashed, one after the other: Engine malfunction, have vehicle inspected; Dynamic stability control malfunction, have the vehicle inspected; Safety and driver support systems partially disabled, drive safely. Vehicle was stuck in high gear and would not shift to lower gear as I pulled into the driveway (fortunately I was close to home), forcing me to have to floor the gas pedal to go up the very slight driveway incline. Dealership thought they fixed the problem, exact same thing happened on 12/28/22 (same dashboard warnings, stuck in high gear) when we were on the highway. Car was barely able to make it up the exit ramp in heavy traffic, could easily have been rear-ended. We were able to get the vehicle home by driving in Manual. It would still not downshift, even in manual, but we managed to get home (about 20 miles) in high gear with slow acceleration. Once again dealership thought they fixed the problem. Exact same thing happened (same dashboard warnings, stuck in high gear) for the third time on 1/31/23. Fortunately I was close to home and was able to pull up the driveway by flooring the gas pedal once again. Car is currently at the dealership service center again. Vehicle has 8,156 miles.

While driving, on approach to a stop signal, at an intersection the car stopped moving. The display said engine malfunction, have inspected. The electronics and engine continued to operate, but the car would not move when gas pedal was depressed. I shut off and restarted my vehicle numerous times, with no effect on the problem, the car still would not move. The vehicle behind me had to brake unexpectedly, and I could have been hit by others in the intersection, there could have been an accident.(I put car in neutral and the driver behind me, pushed my vehicle, manually, out of the intersection) AAA towed vehicle to the dealer I purchased it from, they were unable to reproduce the problem or retrieve codes to identify problem.( AAA did something under the hood before towing and I was able to drive vehicle to nearby parking lot to be towed) No other inspection has been conducted. Over prior week I noted intermittent engine revving while driving for very brief seconds and this occurred just prior to the incident that resulted in the inability to move the vehicle.

As reported by others, Engine Malfunction light came on. Car running rough. Mazda dealer says corroded wiring harness and $5k to replace. They bypass the conventional repair and splice it in. Within a hour of driving after pick up, same engine malfunction light and rough running returns. This time they said I need a new transmission. Electrical issues and faulty transmission are both dangerous. With as much posted online regarding the transmission, I would hope to find a recall. $10k in repairs for a barely 4 yr old car!

Received a "LOW ENGINE OIL LEVEL” warning message before the regular oil change interval of 7,500. Light came on 11/20/24 after purchasing the vehicle from a Mazda dealership 8/10/24 (~3 months). Model and VIN were impacted by the Mazda Valve Stem Seal Settlement. This issue was not disclosed by the dealer.

While I was driving on I-90, I lost control of the acceleration of my vehicle. The vehicle was towed and has been diagnosed with a failed transmission! The car would not accelerate or it would accelerate in bursts or rapidly slow down. I was able to pull over and the car failed to move at all after. My safety and others was put at risk as I lost the ability to control the speed of the vehicle on a road where the speed limit is 65mph in traffic around me. When the problem began no lights illuminated, until ~30 seconds in the yellow engine failure light illuminated and then the yellow transmission failure light illuminated. The car was brought to a dealership for inspection and they diagnosed it as a transmission failure. This is unacceptable for such a young vehicle (2021). It should be noted that the car manufacturer immediately approved the replacement the same day it was diagnosed (dealership said it usually takes 48 hours), but the part is back-ordered for months (probably because they know this is happening and trying to cover it up).

My oil changes were affected as well.

On multiple occasions, low oil warning lamp illuminates and I have confirmed low oil level. Dealer is unable to confirm and refuses to address Mazda TSB because oil level is no longer low since I topped it up. The failure lies in the valve seal assembly. My safety and that of my passengers is affected because in the event of a low oil incident, my ability to safely drive the speed limit and/or accelerate quickly is compromised. Should a catastrophic failure occur, engine would lose all power. Date of most recent incident marked below.

The car's battery has failed two times. The second time is after the battery was replaced -- so the problem was with two different batteries. Both times, I had to call & wait for roadside assistance. Dangerous situation. Both times, the car required a jump-start then a full charge. The dealer denies a battery problem or electrical system problem. However, a Mazda Roadside Assistance service provided advised me on 12/3/2022 that the (second) battery was dead and that something in the electrical system is clearly draining the battery. The car is driven every day. *** Several times a week there is a dashboard notice of "low battery risk". *** This has been consistent, starting with the first week of owning the car. It appears that something(s) in the electrical system is draining the battery to the point of failure. The car is 18 months old with @ 16,500 miles driven. It is a 2021 Mazda CX-30 Turbo Premium Plus. It is available for inspection.
