Mazda CX-50 — Recalls, Reliability, Specs & VIN Decoder

The contact owned a 2024 Mazda CX-50. The contact stated that while driving at an undisclosed speed, after exiting the freeway, the contact was distracted, and when the contact turned to face the road, the vehicle rear-ended the vehicle in front. The contact stated that from the impact, the vehicle that was rear-ended was pushed into the vehicle in front. The contact stated that the crash imminent braking and the forward collision warning failed to function as intended. The contact stated that the driver-side air bag and the knee air bag were deployed. The contact was unsure whether there was a warning light illuminated. A police report was filed. EMS was called to the scene. However, the contact refused to go to the hospital by ambulance. Afterwards, the contact went to the hospital. The doctor diagnosed that the contact had a swollen spleen on the left side. The contact stated that the shoulders and back were sore, and the left knee was swollen. The contact attended physical therapy. The contact was able to drive the vehicle back to the residence. The insurance company towed the vehicle to an unknown location and deemed the vehicle a total loss. The manufacturer was notified of the failure, and a case was opened where assistance was declined. The failure mileage was 16,937.

I am reporting a potential airbag system/emergency brake failure in my 2023 Mazda CX-50. I was involved in a rear-end motor vehicle accident at approximately 60 mph while my vehicle was completely stopped. I then hit the person in front of me. At the time of the impact, the airbags did not deploy, and I received a dashboard message indicating an airbag system malfunction. Since then, the emergency brake turns on and off on it's own at any time. Due to the severity of the crash, I am concerned that the airbags should have deployed, and their failure raises a serious safety concern. I sustained injuries (multiple fractures) as a result of the collision. I am requesting a formal investigation into possible defect or malfunction in the airbag system and emergency brake system.

The contact owns a 2023 Mazda CX-50. The contact stated that while driving at approximately 38 MPH. The contact stated he was approaching an intersection when a vehicle in front of him attempted to make a left turn but slowed down. The contact was unable to depress the brake pedal and turned the steering wheel to the left to avoid the crash, but he crashed into the corner of the passenger side rear bumper of the other vehicle. The contact was not sure of the damage to the other vehicle; his vehicle had damage to the right headlight and the front quarter panel. The contact stated that his vehicle was equipped with a front collision avoidance system, but the system had not engaged. The contact stated that no persons were injured. The contact stated that the police were on scene and wrote a report. The vehicle was driven to a collision center for repair. The contact had not had the vehicle diagnosed. The vehicle had been repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 57,000.

On 1/14/2026, I was pulling into a parking space in a parking garage when the vehicle abruptly accelerated causing the vehicle to hit the concrete wall in front of me. No braking assist or front collision warning issued. Airbags deployed. The car is currently at Joe Myers Collision Center in Houston, Texas to obtain an estimate for repair. The police did not respond to reported incident. Incident was reported to my insurance company immediately.

I have had my 2023 Mazda CX-50 for almost two years. Since I got the car, I have had no issues with the i-Activsense until June 2025. The reason I got the newer car was to ensure the safety of my family; however, Mazda failed to do their part. My car was recently involved in a car accident due to a faulty system. It appears that the newer Mazda CX-50s were included in a recall, but the 2023 model was not and it should be. On the day of the accident, my daughter was driving my car. The traffic was slowing down, and two lanes of traffic had to merge to one lane due to construction and all of a sudden, the car in front of her slammed on their breaks and the car could not stop in time before hitting them. My car never sent an alert until contact was made with the other car, and the emergency breaking did not activate. After my car hit the other car, an alert came on screen that indicated the i-Activsense was disabled. Once the car was turned off and then back on the alert disappeared. Additionally, I am now having issues with the rear camera not alerting if someone is behind me (car or pedestrian). I have a 2019 Jeep Grand Cherokee that will slam on the break for you if you get too close to an object when you are in reverse. Isn't that what the Mazda CX-50 should be doing?

The Collision Avoidance System did not activate, to avoid a front-end collision. The vehicle in front of me stopped, making a right-hand turn onto another road. I moved forward, not seeing him stop. My car rear-ended the vehicle in front of me, with no warning or activation from my system.

I am reporting a severe safety defect on a brand-new Mazda CX-50 Turbo Premium Plus involving a complete failure and malfunction of the Advanced Driver Assistance Systems (ADAS), specifically the proximity, forward collision, parking collision, and automatic emergency braking sensors. The safety sensors continuously malfunction, creating an immediate and erratic hazard while driving. The chief concern is the risk of uncommanded, sudden automatic emergency braking at highway speeds, or the complete failure of critical safety warning systems during a real collision event.Upon identifying this safety risk, I contacted an authorized Mazda dealer to arrange an emergency repair. The dealership explicitly promised a loaner vehicle so they could hold my car safely for diagnostic testing. However, when I arrived, the dealership reneged on the loaner vehicle and refused to check the car into service.Instead, dealership sales and service personnel drove my vehicle into the service bay and instructed me to get inside the cabin. A staff member then entered the vehicle settings menu and manually muted the auditory safety alerts to conceal the active sensor malfunction warnings. I immediately protested, stating that muting a critical ADAS safety warning system was unsafe, did not diagnose or repair the defect, and put my life and public safety at risk. Despite my clear objections, the dealership's management instructed me that I must continue to drive the vehicle with the disabled/muted safety systems anyway and to bring it back if anything else happens.When I refused to accept this hazardous vehicle modification and sought alternative resolution, the dealership owner issued a written communication banning me from the property, entirely refusing to honor the manufacturer's warranty or perform mandatory safety repairs. The vehicle remains unrepaired and unsafe to operate on public roads due to random sensor failures, and the primary local dealer has outright refused service.

I was pulling into a parking spot and the emergency braking system applied the brakes very forcefully as if a collision was imminent. I backed up and saw nothing in the parking spot and then proceeded to pull back into the same spot with no issue. There was a loud and rhythmic thumping sound that I perceived as the abs system engaging. This is a rental car so I am returning it to the company, National rental car, and swapping out for a new vehicle. I contacted Mazda about this and was given a case # 00434431.

Cruise control surges beyond normal limits, has tried to take curves on exits so fast the tires slide and i have to slam on the brakes. Also, when pulling out from behind a car, the cruise control kicks in too fast and is flying toward stopped cars, and i have to use the brake to stop it or rear-end the car in front of me. Also, the fuel system would not allow me to fill up the gas tank, and i was stranded. Computer would not open the fuel tank for me to put fuel into it. Has to pry the entire assembly off and break it. Then fuel would not go into the fuel tank, air pressure kept turning off the pump. After those incidents got the car back from the dealer and two days later it was completely dead in the garage, nothing worked, locks, back latch, etc. When they recarged it there were dozens of codes on.

When approaching cars at an intersection, the brake warning does not give any warning, but the cars brake, lock up, and throw me and anything in the seat flying into the floor or side compartment. It was not even necessary to stop that quickly. Totally random and could cause an accident.

TO NTSA - 2025 Mazda CX-50 Premium Turbo Plus - Purchased [XXX] - Less than 2,000 miles Driving north on [XXX] , I took exit [XXX] . When slowing to change to the right-hand lane, it surged then rapidly accelerated. Stepping on the brake did not slow it down, increased acceleration. To avoid hitting cars in my lane, I jumped the curb to the frontage road, continually pumping on the brake. The left front wheel and axle broke off and landed 20 ft away. The vehicle did not slow down; It was stopped by snapping a power pole in half. While trying to grab my purse, two Good Samaritans yelled at me to get out of the car, it was smoking and there were power lines overhead. Miraculously, I walked away. The Mazda salesman we purchased from was notified with photo. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On 1/14/2026, I was pulling into a parking space in a parking garage when the vehicle abruptly accelerated causing the vehicle to hit the concrete wall in front of me. No braking assist or front collision warning issued. Airbags deployed. The car is currently at Joe Myers Collision Center in Houston, Texas to obtain an estimate for repair.

At 10:16 am, I was driving home on Hall Rd. in Michigan. Hall Road is currently under construction and only two lanes are open and the speed is 40mph. It was raining pretty hard and also very windy. I was traveling West in the left lane and i noticed people in front of me began slowing down to about 10mph and going around an object I couldnt see. By the time it was my turn to pass said object, I realized it was a speed limit sign that had been knocked over by the wind. I went around it and pulled off to the side of the road where there was a small patch of flat, clear land (I believe there is a fire extinguisher or some kind of service system there). Try to act fast, I opened my door, removed my seatbelt and after looking for cars behind me, I ran across the road and picked up the large sign and moved it out of the way. By the time I had moved the sign, I noticed cars slowly approaching but were not willing to pass me. Then I heard them honking their horns but because it was raining hard, I couldnt see who or hear what they were saying. I figured Id look back at my car in case that was the reason and sure enough, it was and I jumped out of the way, and watched my car slowly fall off the ledge of the open roads and into the construction area of the new roads (there was a 2-3 foot deep and maybe 1-2 feet wide trench between the open road and the newly paved roads). My car then stopped abruptly, hanging over the ledge. Seeing the car had stopped completely, I opened the door and slowly got the car off the ledge. This did minor damage to the underside of my front and rear bumper but nothing serious. The problem I feel that is evident is that the car never engaged the electronic parking brake. This was a similar issue to what led to the death of [XXX] (granted, his shifting mechanism was an Audi style shifter and was shift-by-wire). I am not sure exactly what kind of automatic transmission is in my Mazda other than a 6spd. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

There is a recall for earlier models regarding "break clunk." The parking break, when sitting overnight in cold or wet environments, makes a loud bang noise when going into motion for the first time. The parking break seems to be sticking to something.

When using adaptive cruise control, during SOME cornering, SOMETIMES the car brakes unexpectedly, very aggressively, without warning. Very dangerous, especially when another car is behind you.

The contact owns a 2024 Mazda CX-50. The contact stated that there was uneven brake wear on the inner brake pad. The contact stated that the inner side of the brake pads were wearing before the outer sides. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed and determined that the front brake pads and rotors were defective and needed to be replaced. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was approximately 2,500.

I am reporting a potential safety-related defect in my 2025 Mazda CX-50 Preferred, which is approximately four months old. On one occasion, the vehicle moved backward while in Drive mode. This occurred twice on the same day under similar conditions on a slight incline. After starting the vehicle, I shifted into Drive and applied acceleration; however, the vehicle moved backward instead of forward. The rearward motion continued despite active acceleration input. This behavior is not consistent with normal rollback on an incline. The continued backward movement under acceleration indicates a possible issue with transmission engagement, gear recognition, or electronic control systems. I reported the issue to an authorized Mazda dealer. I was informed that shifting the gear too quickly may cause a delay in system response, resulting in the vehicle behaving as though still in Reverse. I consider this explanation unacceptable for a modern automatic vehicle and indicative of a potential defect. This condition presents a safety risk. Unintended rearward movement while in Drive could lead to collisions, especially in situations involving other vehicles, pedestrians, or objects behind the vehicle. Although the issue has not reoccurred since that day, the intermittent nature raises concern about reliability and the potential for recurrence without warning. I request that this issue be investigated as a potential safety defect.

After about six months of ownership, a knocking noise started happening from the front of the vehicle when turning the wheel all of the way to the right. A month or so later I brought it to a Mazda dealership in Green Brook, NJ. I was told by the service advisor that she had the same vehicle and was advised that this was normal. She explained everything exactly as I had experienced it. She told me I could wait in the dealership for 3/4 hours, but the technicians would most likely just tell me the same. Over time, the suspension deteriorated. Bumps felt more and more noticeable and a lot of noise inside the cabin. Specifically, a lot of vibrating on the right side of the vehicle: windows, front passenger seat, and the trunk window. Looking over the internet, it seems like this problem is apparent in multiple vehicle years, but never properly addressed via a recall: [XXX] . The vehicle is currently in Sansone Mazda in [XXX] . They replaced the right CV and the problem did not go away. I was told they would have to contact Mazda corporate. They did and I was then advised that they would need to replace the left CV axel, as well. Not surprisingly based on the frequency of this issue, that part was unavailable and on back order. I don't know how long I'll be without my car at this point. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Clicking /rattling noise when turning

Driver side and passenger side axle-area damage, making loud clicking and popping sounds on turns indicating major damage to CV joint, at around 5000 miles. Primarily heard on sharply turned wheel acceleration, particularly on slightly uphill inclines.

Vehicle: 2025 Mazda CX-50 Hybrid Mileage at first failure: ~6,000 miles Component: Front CV boot / axle assembly — loss of grease Safety Concern: Early-life component failure with unresolved uncertainty in root cause Description: At approximately 6,000 miles, the left front CV boot of my vehicle was found leaking grease. The dealership initially stated the failure was due to “external impact,” but no conclusive evidence was presented to support this determination. The photos and inspection notes did not identify a clear puncture or specific point of impact. Mazda Corporate later informed me that their engineering team concluded the issue was not related to a material or manufacturing defect, and offered a goodwill repair. However, the underlying root cause remains uncertain due to the lack of definitive evidence. Safety relevance: A CV boot failure at such low mileage is extremely unusual for a modern vehicle, and premature loss of grease from the CV joint can lead to: joint degradation, reduced steering stability, potential loss of vehicle control. If similar early-life failures occur on additional Mazda vehicles, this may indicate a broader design, material, or assembly concern. Requested Action: I am submitting this report for documentation purposes in case a pattern emerges or if the issue recurs on my vehicle or others.

At only about 6,100 miles and during my vehicle’s first service, the technician found grease leaking from the left front CV boot. The dealer stated this was caused by an external puncture, but they were unable to provide clear evidence, detailed photos, or a written diagnosis proving that the damage was external. The mark they referenced was extremely small and not consistent with a clear impact. A CV boot should not fail at such low mileage, which raises concerns about a potential early-life component failure or material defect. A torn CV boot can lead to CV joint wear, loss of power, or loss of vehicle control if it progresses. Because the root cause is uncertain and the failure occurred unusually early in the vehicle’s life, I am reporting this to NHTSA in case this represents a broader quality or safety issue affecting other vehicles of the same model.

I brought my vehicle to Modern Mazda of Thomaston, CT on Friday January 30, 2026 due to a front-end passenger clunking noise that occurs during left turns. The master tech test-drove the vehicle to duplicate the noise and video of the damage. I was informed that the front passenger axle was leaking grease in video and recommend to replace the front axle. I was told the necessary parts are on back order 6-8 weeks. I was told Mazda is aware of the manufacturer workmanship defect in the CV axle parts. The service manager did provide written documentation ordering the parts. I did file a complaint with Mazda Corporate, documenting the issue and the dealership's findings as well as I was informed the fact Mazda is seeking a new supplier of CV parts. A Mazda corporate case number was assigned. I believe this is a safety issue and a recall should be issued.

I am reporting a potential safety-related defect involving premature axle failure on Mazda CX-50 vehicles. The axle appears to be prone to early failure under normal driving conditions, sometimes at relatively low mileage. There are multiple reports from other Mazda CX-50 owners describing similar axle or CV axle failures, including clicking noises, vibration, loss of power to the wheels, and complete axle failure. These reports are publicly documented on online owner forums and Reddit, suggesting a pattern rather than isolated incidents. Axle failure can result in sudden loss of propulsion and may increase the risk of a crash, especially at highway speeds or during turns. This appears to be a design or durability issue rather than normal wear and tear. I am concerned this defect affects multiple vehicles and warrants investigation and a potential recall before more failures occur.

I brought my vehicle to Safford Mazda of Fredericksburg on Monday, December 15, 2025 due to a front-end clunking that occurs during left or right turns. A service representative test-drove the vehicle with me and was able to hear and duplicate the noise. Shortly afterward, I was informed that the front axle has internal damage and that the vehicle would need to be retained by the dealership for repair. I was told the necessary parts would not be available until sometime in February 2026. The dealership retained possession of the vehicle and arranged a loaner vehicle for my use. The service manager declined to provide written documentation stating that the car was unsafe to drive or describing potential consequences of continued operation. However, the vehicle was not released back to me pending the axle replacement. I have filed a complaint with Mazda Corporate, documenting the issue and the dealership's findings. A Mazda corporate case number is available if needed.

On three separate occasions, while in reverse backing out of my driveway, the car failed to engage the transmission when shifting into drive, acting like it was in neutral. There were no warning lights or messages on the dashboard. The only way that I found to engage the transmission was to turn off the vehicle, turn back on, and move selector to drive. This is a safety issue as I've had cars approaching in both directions with the CX-50 behing immobilized and not able to move out of the roadway.

Vehicle was dormant overnight and caught fire. Battery disintegrated and fire tore across the entire engine compartment and front end. Fire department conducted investigation and determined mechanical failure. Showed no signs of issue before hand was driven shortly the night before to move parking spots.

Stopped at a convenience store in [XXX] . Upon return to vehicle, it would not start. A check engine light and steering alert came on. According to ChatGPT it appeared to be an electrical problem. AI recommended that the vehicle be "rebooted". That entailed putting the car in Park, turning the ignition off, turning off all accessories, getting out of the car, locking it with the FOB, and walking away from the car with the FOB. Don't return until after 5 minutes or more. The second incident occurred on the out skirts of [XXX] . The instrument panel went dark for a half a second or so. Once it became illuminated, another warning alert appeared: Telematics Communication Unit Malfunctioned. AI suggest not turning ignition off until we reached our final distination.

We have had this 2025 Mazda CX-50 hybrid for a couple of months. On January 21, 2025, my wife tried to start it after shopping at a Dollar store. All the warnings lights came on, blinking, and the car was unresponsive to drive. After repeated attempts to start the car, the warning lights, finally, did go off, but a message of "hybrid system malfunction have vehicle inspected" came on. It finally started and allowed her to drive home. The alert about the hybrid system went off. So far, it has not happened again. I called the service department, and all they said was to bring it in if it does it again. No one has looked at it. Really wasn't any risk to her since she was in town. But had it happened somewhere where she didn't have phone service, it could have put her at risk. I don't really know what happened, but the biggest thing is the worry that it will do it again.

The vehicle had the original OEM battery fail at 15 months. It dropped to 7v under light load. It's a bad battery. Upon being jump started, the power steering went in and out while driving and the dashboard blinked on and off...throwing a lot of errors that are unrelated to the battery problem. The failure state of the vehicle with a bad battery is unlike any vehicle I have ever seen and it is extremely dangerous. Furthermore, Mazda roadside assistance does not know about this issue and only offers jumpstarts, putting customers into danger by suggesting that the vehicle is safe to drive with a battery that is not stable.

The contact owns a 2024 Mazda CX-50. The contact stated that while reversing at approximately 2 MPH into a parking slot, the rear back up sensor warning was illuminated. The contact stated that the sensor was designed to alert the driver whenever the vehicle was too close to an object. The contact stated that the rear collision braking system warning was also illuminated. Additionally, the contact stated that a factory installed trailer hitch warning was also illuminated intermittently. The contact stated that the electrical failure was intermittent and occurred at various speeds. The contact stated that while depressing the brake pedal, the front brakes were making an abnormal rubbing sound. The contact stated that after releasing the brake pedal the sound stopped. The contact stated there was no warning light illuminated. The contact had taken the vehicle to a local dealer, who was unable to duplicate the failure. The contact stated that the vehicle had been taken to the same dealer several times. The vehicle was not diagnosed or repaired. The manufacturer was informed of the failure. The failure mileage was 13,522.

Automatic transmission failure, engine malfunction, safety driver function. My car will not accelerate, or move out of 1,2,3 gear.

The temperature control dial on the climate control system behaves erratically and inconsistently. When turning the dial to increase temperature, the displayed temperature sometimes decreases. When turning it to decrease, it sometimes increases. The dial also jumps multiple units rather than incrementing one degree at a time. The behavior is unpredictable and occurs regardless of whether the engine is warm or cold. This issue has been confirmed by multiple other 2023 CX-50 owners in owner forums, suggesting a manufacturing defect in the encoder mechanism for the temperature control knob. The dealer confirmed the bumper-to-bumper warranty has expired but has not offered a resolution.

When adjusting the temperature in the car with the dial, it does not respond correctly. It either jumps up or down by multiple degrees. This causes to take your eyes off the road to try to adjust the temperature. No warning lights came on and pushing lighter or harder on the dial does NOT fix it. Only driver side is currently having this issue.

1) Climate Control System Malfunction I am reporting a safety-related defect involving the climate control system in my vehicle. Specifically, the temperature control knob is malfunctioning and behaves erratically. When adjusting the temperature, the system does not respond consistently and will unpredictably change temperature settings without corresponding input. This was diagnosed at The Autobarn Mazda of Evanston to be a failure within the HVAC control system. I see it is a common issue discussed in online forums. The issue has been diagnosed and confirmed by a service technician. At this time, the vehicle has not been fully repaired and remains available for inspection upon request. This malfunction creates a potential safety risk because it may cause a distraction while driving. The erratic behavior requires repeated adjustments and attention to the climate control system, diverting focus away from the road. The problem has been reproduced and verified by a dealership technician, who confirmed the abnormal operation of the temperature control knob and system. A repair was recommended, with replacement cost $690.24. The vehicle has been inspected by an authorized dealership, and I also contacted Mazda to request goodwill repair assistance. However, they declined to cover the repair cost. My car has 55,000 miles, but this is an issue that has been present early on if not since day 1. Prior to the failure, there were no consistent warning lights or system messages indicating a problem. Given that this appears to be a known issue with this type of system, I am concerned that other vehicles may be affected by the same defect.

The contact owns a 2024 Mazda CX-50. The contact stated that while opening the doors, the door stop detent had failed, causing the door to rapidly close and swing back, and making contact with the occupants. Both the contact and the wife sustained leg bruises, and the wife sustained a head contusion due to the failure. No medical treatment was required. The contact indicated that the failure was present on both the driver's side front and rear doors and the passenger side front and rear doors. The cause of the failure was not determined. The vehicle was taken to the local dealer, who examined the vehicle, and no failure was found. The contact was informed that the door operated as intended. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 100.

Door handle cables detach easily which prevents the door from being opened from the inside. It has happened to me twice on my driver side door the last 5 months. Research online shows this is a very common problem with newer Mazdas and it is a major safety hazard as it prevents easy exit from the vehicle in the event of an emergency, especially if there is power loss so the windows cannot be opened.

An indentation in the rear bumper may be noticed SAME AS sa035/22 BUT DEALER said is not applicable to my vehicle even when is the same deffect.

First issue: Rough idle at start. The interior cabin vibrates enough to question the vehicle quality. The rough idle lasts about 40 seconds then engine switches to smooth vibration. It's actually unnerving. Second issue: it's well known in 2025 Mazda installed the Toyota RAV4 hybrid engine and transmission into the CX-50. The current ICE engine model had to be modified. As a result there are some structural issues that may become problematic. The front passenger door scrapes against the interior fender. During manufacturing to cover up the defect Mazda purposely offset the passenger side fender mask the defect. This should seriously can into question the structural integrity of the vehicle. The primary concern is by offsetting the fender have the impacted the ability of the crumble zones in this area? Additionally, the front passenger door may become stuck since there is no uniformity in the panel alignment. This should raise caution since the modifications necessary to accommodate the hybrid system my have impacted overall vehicle integrity.

I was attempting to mount my bike rack. To get the clips to properly fit I needed to partially open the liftgate. Upon triggering the door release the power liftgate and began opening the door. The anti pinch system did not detect the pinch and it crumpled the roof and liftgate at the seam. I tried to stop it but there was too much pressure and by the time it stopped lifting under my body weight significant damage had occurred. If a finger had been there it would have been chopped off.

The vehicle hood has an angled section near the windshield that causes sunlight to beam intensely, directly into the drivers eyes when driving with the sun in front of the vehicle.

Window shattered while idle.

Water leaking to right rear cargo area after rain that makes the roof trim wet, the cargo floor and spare tire compartment flooded. The water seems to flow out from seat belt opening.

The driver's door is not opening from the inside. To open the driver's door while I am in the vehicle, I have to roll down the window and use the exterior door handle to exit the vehicle. This is a huge safety concern, as the window cannot be rolled down manually. If the car did not have power, I would have to break open the window. The potential for being trapped in the car with this defect is high.

My ball joint failed on my brand new 4 month old vehicle at mile 2077. You absolutely have the ability to inspect it if you would like. This caused a MAJOR safety issue to both me and people around me as I lost complete control of my vehicle. Luckily, no one was injured. I believe this is an independent claim thus far on a CX-50. Mazda claims they had it inspected but I never saw anything in writing but I did have a damage adjuster of my insurance checked it out. I was stated my an independent mechanic and a tow truck driver that I did not cause this and something failed. Mazda also claims the district manager has looked at the vehicle and they don’t know how or what happened but they do not claim responsibility even though my car is covered in warranty. There were no warning lights or anything that told me this was going to happen, when my control arm popped off it veered me into a curb and blew my tire, losing control of the car, and skidding to a stop across an intersection

Gradually increasing knocking and clicking sounds from front end suspension through first 400 miles of new car miles was observed. Researched this issue and found known recall for this specific problem for same model/year but VIN was not identified within the known range. Reported to dealer/mazda service center and told to bring vehicle in for inspection with reported confidence that this is the same known problem.

Driver side and passenger side axle-area, making loud clicking and popping sounds on turns indicating major damage to CV joint, at around 10,000 miles. Primarily heard on sharply turned wheel acceleration. Two dealerships said they "couldn't reproduce the issue" even though I showed them the issue on recorded video. I demand that this be taken seriously as a recall.

Mazda CX-50 at 22000 miles CV joint on passenger side making clicking sound under moderate acceleration. Scheduled service with dealer on 1/28 received appointment date of 3/2 for inspection and possible repair.

Vehicle CV joints failed at 6000 miles, dealership took over 3 weeks to replace them. They claimed multiple CX50 hybrid vehicles are impacted and lots of them already returning under the same problem

I am reporting a potential safety-related defect involving premature axle failure on Mazda CX-50 vehicles. The axle appears to be prone to early failure under normal driving conditions, sometimes at relatively low mileage. There are multiple reports from other Mazda CX-50 owners describing similar axle or CV axle failures, including clicking noises, vibration, loss of power to the wheels, and complete axle failure. These reports are publicly documented on online owner forums and Reddit, suggesting a pattern rather than isolated incidents. Axle failure can result in sudden loss of propulsion and may increase the risk of a crash, especially at highway speeds or during turns. This appears to be a design or durability issue rather than normal wear and tear. I am concerned this defect affects multiple vehicles and warrants investigation and a potential recall before more failures occur.

I purchased my vehicle early August 2024 at Knudson Foothills Mazda in Spokane, Washington. Within the first five hundred miles of use, I noticed that my steering wheel would not maintain center alignment. I took it into the shop explaining my issue and they were fast to acknowledge the alignment was off and that they realigned the vehicle. The steering was off center alignment within 20-40 miles so I again, contacted the dealer and told them I expect a more thorough inspection. They took a brief inspection and realigned the vehicle again. At pickup, the service advisor said "the suspension is settling, this is normal. If it happens again, don't bring it back for 5K miles." They also proceeded to tell me they could not determine the cause, so they called the Mazda Technician hotline which is where they claimed to have got their answer for me. The center alignment did not last more than 20ish miles and has gradually gotten worse. If this were "normal", they would have been able to tell me on the first visit instead of two and having to call their own tech hotline. If this were "normal", I would be able to find reputable sources online confirming this. If this were "normal", I would not have been told to endanger my life for an extended 5K miles before asking for this to be fixed again. I do not feel safe in my car. Each time I call the dealer they tell me to wait until 5K miles. I have filed a complaint with Mazda USA but have not heard anything since. I'm currently looking into attorneys to go after Mazda USA as I feel the vehicle is UNSAFE to drive and they are being NEGLIGENT on their approach with total disregard to consumer safety. Searches online indicate this is likely a result of faulty parts used when the vehicle was manufactured. I do not know what else do to besides file this complaint so a large entity can question Mazda on this SAFETY ISSUE. 1st service/realignment: 9/16/24 - approx 750 miles 2nd service/realignment: 9/25/24 approx 1251miles

Vehicle steering failed and caused the vehicle to go in opposite direction than intended, ended up almost hitting a streetlamp due to this. Issue had happened before and ended up on opposite side of traffic but had attributed it to loss of traction and wet weather at the time, but likely related to this. reported to dealer and they were unable to recreate or find any issue

Wear of Strut Bearing causing crunching sounds at low speed braking and turning. Dealer reports this is due to dirt and debris getting up there. Vehicle has 34,000 miles (out of warranty due to time) and has had only light use off-road on dirt roads (2 camping trips). Not repairing can cause further damage and failure of suspension components. Vehicle marketed as off-road capable but components not protected properly from dirt/debris from driving off-road.

On [XXX], our 2023 Mazda CX-50 experienced a failure of the control arm, which was confirmed by Auffenberg Mazda of O’Fallon, IL, to be a manufacturer’s defect. Despite this, the dealer informed us that the vehicle was safe to drive. However, Mazda corporate contradicted this, stating the vehicle is unsafe to drive and instructed us not to operate it. We were informed that the replacement part will not be available until sometime in July 2025, leaving us without a safe vehicle for nearly two months. Both Mazda corporate and Auffenberg Mazda of O’Fallon, IL, have refused to provide a loaner vehicle or commit to reimbursing rental car expenses during this period. Additionally, Mazda corporate has failed to maintain consistent communication, not returning calls when promised and leaving us without timely updates or resolution. This situation poses a significant safety concern and financial burden, as we are left without a reliable means of transportation due to a confirmed manufacturing defect. We request that the NHTSA investigate this issue, including the conflicting safety assessments provided by the dealer and Mazda corporate, the delay in part availability, and the refusal to provide a loaner vehicle or rental car reimbursement. We also urge an evaluation of the control arm defect to ensure other Mazda CX-50 owners are not at risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle was dormant overnight and caught fire. Battery disintegrated and fire tore across the entire engine compartment and front end. Fire department conducted investigation and determined mechanical failure. Showed no signs of issue before hand was driven shortly the night before to move parking spots.

On 1/14/2026, I was pulling into a parking space in a parking garage when the vehicle abruptly accelerated causing the vehicle to hit the concrete wall in front of me. No braking assist or front collision warning issued. Airbags deployed. The car is currently at Joe Myers Collision Center in Houston, Texas to obtain an estimate for repair. The police did not respond to reported incident. Incident was reported to my insurance company immediately.

First issue: Rough idle at start. The interior cabin vibrates enough to question the vehicle quality. The rough idle lasts about 40 seconds then engine switches to smooth vibration. It's actually unnerving. Second issue: it's well known in 2025 Mazda installed the Toyota RAV4 hybrid engine and transmission into the CX-50. The current ICE engine model had to be modified. As a result there are some structural issues that may become problematic. The front passenger door scrapes against the interior fender. During manufacturing to cover up the defect Mazda purposely offset the passenger side fender mask the defect. This should seriously can into question the structural integrity of the vehicle. The primary concern is by offsetting the fender have the impacted the ability of the crumble zones in this area? Additionally, the front passenger door may become stuck since there is no uniformity in the panel alignment. This should raise caution since the modifications necessary to accommodate the hybrid system my have impacted overall vehicle integrity.

Check engine light came on at 600 miles. Took it to the dealer and the code was a p3400 code, cylinder deactivation fault. The dealership replaced both solenoids, part #PYFA-12-360A, found metal in OCV valves. When we got the car back I changed the oil, cut the oil filter open and found large metal shavings. At about 1300 miles the same check engine light came on. Back to the dealership with the same code. Now Mazda says to replace the head.

The vehicle jerks while slowing down/low speed.

Automatic transmission failure, engine malfunction, safety driver function. My car will not accelerate, or move out of 1,2,3 gear.

I purchased this brand new 2023 Mazda CX-50 at the end of this July, and it has no incidents, no hits, no scratches at all. Last Sunday while driving it, out of no where, the 'Vehicle System Malfunction' message showed up and I dropped my car at the dealership right away. There was the weird sound from the front of the vehicle every time I braked to 10 mph, and I don't want to take risk of my own to drive it anymore. The front right-side lower active grille shutter was broke, and three lit damages were spotted on the condenser behind it. Luckily no leakage happened at that time. The dealership gave it a rounded inspection and told me 'it might be hit by a little rock'. Yeah, a little rock broke the entire grille shutter. I realize that there is no protection of any sort in front of the shutters, and it is very easy for any little object to break the shutters and the condensers as well. You can see easily from any picture of a CX50, there are two open big holes at the lower front, and the shutters are inside. This makes the shutter entirely expose. It's only two months since I bought this car, I believe I will not be the first CX50 owner that has this problem. It is highly possible that this is a design flaw, there should be some protective manners in front of the shutters to reduce the possibilities of something hitting it. Mazda's warranty is not covering this since they told me 'it was damaged by hitting a little rock', but this damage was because there is no protection to the shutter at all.

I am reporting a severe safety defect on a brand-new Mazda CX-50 Turbo Premium Plus involving a complete failure and malfunction of the Advanced Driver Assistance Systems (ADAS), specifically the proximity, forward collision, parking collision, and automatic emergency braking sensors. The safety sensors continuously malfunction, creating an immediate and erratic hazard while driving. The chief concern is the risk of uncommanded, sudden automatic emergency braking at highway speeds, or the complete failure of critical safety warning systems during a real collision event.Upon identifying this safety risk, I contacted an authorized Mazda dealer to arrange an emergency repair. The dealership explicitly promised a loaner vehicle so they could hold my car safely for diagnostic testing. However, when I arrived, the dealership reneged on the loaner vehicle and refused to check the car into service.Instead, dealership sales and service personnel drove my vehicle into the service bay and instructed me to get inside the cabin. A staff member then entered the vehicle settings menu and manually muted the auditory safety alerts to conceal the active sensor malfunction warnings. I immediately protested, stating that muting a critical ADAS safety warning system was unsafe, did not diagnose or repair the defect, and put my life and public safety at risk. Despite my clear objections, the dealership's management instructed me that I must continue to drive the vehicle with the disabled/muted safety systems anyway and to bring it back if anything else happens.When I refused to accept this hazardous vehicle modification and sought alternative resolution, the dealership owner issued a written communication banning me from the property, entirely refusing to honor the manufacturer's warranty or perform mandatory safety repairs. The vehicle remains unrepaired and unsafe to operate on public roads due to random sensor failures, and the primary local dealer has outright refused service.

I get an error that rear side radar obsured, I activsense temporarily disabled almost everytime I drive at freeway speeds. It disables the blind spot monitoring making the vehicle less safe. It disables for long periods of time in all conditions. Took to Mazda and they indicated it’s an issue, but no solution.

The blind spot monitoring stops after a few minutes on the highway. Dealer said no trouble foun d. When in traffic it stops working, backing up no notification cross traffic, cargo door stuck open. Adter 10 minutes shutting off car. Restarting, trying inside button, door button and the remote. They all failed to close door. Had to manually close cargo hatch. It worked the next morning. The blind spot, cross traffic doesnt work! It works for a few minutes after starting car but under traffic condtions it fails to notify on both sides of the vehicle. It failed first on passenger side. Now both sides fail in heavy traffic conditions. I have videos to prove the failures.

For about one week now. The blind spot monitoring system fails in heavy traffic. It works when you start the car, works in lite traffic. But on the highyway or heaver traffic it stops working. The dealer said it worked when test driven for 10 minutes. After blind spot stops functing then the cross traffic alert fails. Our cargo bay door refused to close yeaterday. All buttons just cause a beep to sound. After 10 minutes , restatring the car, locking & unlocking the doors by remote & inside switch. I had to physically close the hatch against the motor. The blind spot failed on the ride home from the dealer when surrounded in traffic. Video made of failuer.

Automatic transmission failure, engine malfunction, safety driver function. My car will not accelerate, or move out of 1,2,3 gear.

Safety systems disables when Sunlight hits directly on the car. I own Toyota and honda, they Never had problems with sunlight. sudden loss of safety systems, caused warnings on dash, which was a distraction, especially when Sun hits directly at the car/driver. I verified the camera and sensors, there were very clean.

Lane keeping assistance does not prevent the vehicle from departing the lane nor does it provide corrective steering. LKA is fully activated and vehicle travelling over 45 mph on highway with clearly marked lanes; vehicle drifted across three lanes with zero corrective action from LKA.
