ENGINE

42 complaints

Vehicle experienced sudden engine malfunction including rough idle, hard misfire, and flashing check engine light. Vehicle was diagnosed with a collapsed lifter and internal engine failure. Metallic debris was found in the engine oil, including silver and gold/bronze particles consistent with bearing material. A Chevrolet dealer inspected the vehicle and determined that the engine requires complete replacement due to internal mechanical failure. Vehicle is equipped with the 6.2L V8 (L87) engine. The failure occurred without warning and presents a safety concern due to potential loss of propulsion. This vehicle is not currently included in the existing GM 6.2L engine recall, despite exhibiting the same failure characteristics reported in other affected vehicles with the same engine and year that were included in the recall. Vehicle has not been driven since metal contamination was discovered to prevent further damage

Went into limp mode on 11/6/25, took to the dealership where they found metal shavings in the oil due to a “stuck solenoid ‘A’”. Originally said that I’d need a whole new transmission, decided to do the cheaper easier repair and just replaced the valve train (not my choice) got it back on 11/13/25. On 11/24/25 I was on a very busy highway, at a red light, hit the gas when the light changed and the car didn’t move. Just revved the RPMs, then it suddenly lurched/surged forwards. Took it back to the dealership and they said “it doesn’t have any codes showing”. This is not normal behavior for a 4 year old vehicle with less than 40k miles on it.

Nov 25, 2025

We have a defective engine that stopped working after 120 miles. We can drive the car because it can leave us on the road or catch fire, this is what the mechanic told us, GMC option is to buy another car.

Nov 21, 2025

Engine is shaking like a bearing is going out, I've seen multiple recalls on this engine but for some reason my 6.2 isnt apart of them.

Nov 08, 2025

CAR BURNS EXCESSIVE AMOUNTS OF OIL AND HAVE TO ADD REGULAR QUARTS OF OIL BETWEEN THE MANDATORY OIL CHANGE. CONSIDERED VEHICLE COULD MALFUNCTION AND CAUSE AND ACCIDENT OR CATCH FIRE. DEALER SAID THEY HAVE RECALLS FOR OTHER CHEVY SUVS AND TRUCKS WITH SAME ISSUE BUT NOT MY PARTICULAR MAKE AND MODEL. THIS ISSUE WITH CHEVY'S BURNING OIL WARRANTS AN INVESTIGATION SINCE CHEVY IS NOT ADDRESSING THE ISSUE.

Jul 07, 2025

The vehicle started rumbling/vibrating/shaking when getting up to speed and at a consistent speed. Brought to an independent service center and was old that the torque converter is failing. No warning lamps or other problems prior to rumbling/vibrating that started on 5/22/25.

Jun 19, 2025

While driving at normal highway speed, the vehicle speed is suddenly reduced and it feels and sounds like the transmission has shifted into low gear. The following warning light activated: Reduced Acceleration Drive with Care. The GM dealership service center stated that the transmission control valve body needed to be replaced. They indicated that this was a known issue. I believe a safety recall should be issued for this defective part.

May 20, 2025

History of transmission shifting issues shortly after purchase (CPO from Dealership). Vehicle was taken to two separate dealerships, several times for this issue while still under the 100,000 mile CPO warranty. Dealerships claimed they could not replicate the issue, however problem continued. Now at 1198xx miles, the transmission failed while driving. was accelerating from stop and and the vehicle bucked, the rpms jumped, the service indicator illuminated, and when the vehicle stuck in limp mode. I spoke with one of the dealerships and explained the history and suggested my vehicle failure was exactly as described in the safety recall and they informed my VIN was not included in any recall or service campaign and the could do nothing for me. I called the GM customer service number, pled my case and was told the same thing

Apr 02, 2025

After making a left turn on the street and picking up speed to 30mph the vehicle suddenly almost stopped and the engine raved up. It was so dramatic and unexpected that we thought the vehicle behind us was gonna hit us. Now vehicle only drives forward without shifting gears and doesn’t go reverse.

Driving vehicle on a highway at 55mph, tried to speed up, no propulsion. Fuel injector went bad.

Aug 31, 2025

I was standing at a red light with my foot on the brake and the car went into neutral and stalled. I could not restart the vehicle and had to be towed to the dealership where there confirmed a fuel pump module failure. There were no precipitating factors or warnings. This is extremely dangerous. The car is only 4 years old and many people have reported the same incident online, which often recurs, even after replacing the fuel pump. The dealership has ordered the part however it is on backorder without any estimated ship time. For a vehicle I paid over $70K for, this is concerning and frustrating. There is a known recall for 2021 Suburbans for this exact issue.

Car would not start. towed into dealer for repair. This is the second time this has occurred, a well-known issue with GM trucks. on both occasions was a defective part, Fuel pump power control module.

Apr 27, 2025

The fuel tank strap bolts became loose and fell out, causing the fuel tank to drop. The vehicle has the original fuel tank and to our understanding, it has never been removed. We purchased the vehicle new and are the only owners.

EXTERIOR LIGHTING

5 complaints

The headlight adjustment screw is broken. Was never used or adjusted and now the headlights point to the ground. GM does not offer a replacement part for the adjustment screw, the only fix is to purchase a whole new headlight assembly which is roughly $1,000 before installation costs. This causes a dangerous situation since the drivers side headlight points to the ground and it is hard to see in front of you at night.

Sep 17, 2025

The headlamps are defective and unexpectedly break causing them to aim basically straight down towards the pavement making it unsafe to drive at night. In February of this year I took the vehicle to Cox Chevrolet in Bradenton and they said the headlamps would need to be replaced and it would cost several thousand dollars. I rarely need to drive at night and have been taking our son's car since then. There is a chance one broke and I didn't notice at first then the second one but, at this point, it is unsafe to drive the vehicle at night. I have found several posts on online forums where owners of other GM/Chevrolet vehicles with the same headlamps have had the same experience. Some have mentioned that an adjuster pin breaks and is not repairable (which I have confirmed with a service advisor at another Chevrolet dealership). I am [XXX] who drives responsibly (i.e. not going off road in my Suburban) so having an issue like this is of concern as it makes the vehicle suddenly unsafe to drive at night. This is not a defect that is noticeable during the day so anyone purchasing a used vehicle with this problem wouldn't know they essentially don't have headlamps (I can see maybe 10 feet in front of the car) until they get on the road at nighttime.

The headlight adjuster failed. As a result, the headlight points straight down creating a safety issue at night. I have read online this is a common problem on suburbans and tahoes. This happened on my car around 60k miles and only ~3 years.

Oct 25, 2024

While night driving driver noticed the driver side headlight completly pointing down providing no visibility. Vehicle was brought into GM dealership where is was discovered the Driver LED headlight adjuster screw broken causing a safety issue, where the light beam pointed down. Vehicle light assembly is currently being inspected for replacement under manufacture warranty under 36,000 miles.

The contact owns a 2021 Chevrolet Suburban. The contact stated while driving 45 MPH, the driver’s side low-beam headlight was pointing inward, affecting his visibility of the roadway. The contact stated that the failure later occurred with the passenger’s side low-beam headlight. There were no warning lights illuminated. The vehicle was taken to the dealer who diagnosed that the headlights needed to be replaced. The manufacturer was not notified of the failure. The vehicle was not repaired. The approximate failure mileage was 62,000.

ENGINE AND ENGINE COOLING

4 complaints

See attached document for complaint. To Whom It May Concern, I am writing regarding the recall on my 2021 Chevy Suburban. While I understand there is currently no active solution for the issue, I want to stress the seriousness of the situation. As a mother of [REDACTED] living in Wisconsin, I am deeply concerned that if my truck were to shut down due to engine failure and we could not get help quickly, my family would be exposed to the risks from the fire that inevitably could arrive. Given the harsh winters there, this poses an unacceptable safety risk. Additionally, I paid for an extended warranty, believing I had plenty of coverage left. I recently brought my vehicle in only to be told that I was 500 miles past the 60,000-mile limit, I was under the impression the warranty had not expired, and if I had known otherwise, I would have brought it in much sooner. This issue has been ongoing for at least 6 months, and I have been aware of the mileage restriction, I would have scheduled service well before this point. On top of that, my Suburban continues to emit the smell of burnt oil. It is embarrassing to have my vehicle smell like it's burning every time I drive it, and it raises serious concerns about my health. Breathing in burnt oil fumes regularly cannot be good for my lungs or overall well-being. This issue has also created a financial burden for me, as I am currently trying to sell the vehicle. In its present condition—with the burning oil smell and unresolved recall—it is essentially unsellable. No buyer wants to take on these risks and uncertainties, leaving me stuck with a vehicle I can neither comfortably drive nor reasonably sell. This matter is not just about inconvenience. It is about safety, that matters, and other concerns, trust and accountability. Chevrolet has marketed its vehicles as reliable, family-safe transportation, and I want to feel assured that GM takes immediate action to properly address this oil consumption and/or issue. Anything less is unacceptable when it comes to the safety of families who trust your brand. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

SERVICE BRAKES

3 complaints

My wife was driving the vehicle and was pulling into a parking lot. The brakes failed and would not stop the vehicle. She pressed on the brakes very hard, multiple times, for several seconds, before the vehicle finally came to stop. She then proceeded into a parking spot where the brakes again failed to stop the vehicle promptly. Several lights illuminated and a “System Brake Failure 43 MPH Top Speed” message appeared, alternating with several other messages appearing. The vehicle is in for service at Classic Chevrolet in Granbury, Texas. They are telling me that they reset the codes and that the codes are not returning. I am extremely concerned that if I pick up the vehicle at this point, the brakes could fail again and cause an accident with serious injury.

Jul 16, 2025

brake master cylinder failure, took car to chevy after brakes got super hard to push , luckily no accident , felt like no brakes, at the point of failure, brake light, abs light, check engine light all went on ,at some point abs and brake light went off but check engine light stayed on and screen on Dash indicated max speed 62 then in a couple of minute screen showed max speed 42 mph , then lights go off except check engine and vehicle works as it should it randomly does this in one day so vehicle was taken in to dealership where they had a hard time figuring out if thats the problem and contacted gm tech support gm and they said with these codes it should be the brake master cylinder, and it would cost me 3000.00 to fix. on an 80 000.00 car that's a 2021 with 82,000 miles and they are pretty certain that will fix the problem, I'm pretty sure I don't want to get in an accident at 65 to 70 mph and die I feel this is a huge safety issue and thank god wife and kids weren't in the car considering this is my wife's car to drive the kids around in

Jan 07, 2025

At approximately 43,000 miles driving down the highway and lost power braking followed with a number of dash messages and lights. Took to dealer to discover the ABS Master Cylinder is bad and needs replaced and parts are 2 weeks out to have repaired. It appears after reading online this looks to be a problem with numerous people leaving comments etc.

There is an issue with the transmission when i accelerate at a slow pace. The car shakes and vibrates. Theres a possibility of an issue with the transfer case 4x4. When i turn the steering wheel and drive, it feels like it locks. It feels like 4x4 is on and theres a odd sound as well. I took my car to Hamilton Chevrolet and paid for inspection. They told me that there was no issue, but the issues i mentioned earlier in this message was mentioned to them. Those issues are still occurring. This is a recall issue but when i put my VIN number in, my car shows that there is no recall on it. There was many people who mentioned this problem.

I am contacting you regarding a critical engine failure in my 2021 Chevrolet Suburban LT, which is equipped with the L84 5.3L V8 engine. Due to a valve lifter malfunction, the engine suffered catastrophic failure, with metal shavings found throughout the oil system and internal components. I’ve been quoted approximately $14,000 by the dealership/service center to replace the engine, and the vehicle is currently awaiting repair. I was driving the car with my son when the vehicle began to shake, make ticking noises, and the check engine light went on. I pulled off the road and several error codes popped up including "Service ESC" and "Service Traction Control." This is the second time that a lifter valve has failed on this vehicle. In 2022, the lifter valves on the left side were replaced under warranty. It appears one of the left side lifter valves failed again, this time causing significant cam shaft damage and damaging the engine. Given that this issue appears to be affecting many owners with similar engine configurations, I would appreciate your assistance in investigating this matter to see if these issues stem from possible manufacturing defects which could result in engine damage or failure. I reached out to General Motors to ask if I qualify for extended coverage or any known service programs to address this situation and they told me I should talk to the dealership because they are unwilling to offer assistance. I've attached receipts for repair of the lifter valve in 2022 and the current diagnosis of engine failure, cam shaft damage, and lifter valve failure. This vehicle is only four years old and was regularly serviced by General Motors. It is available for further inspection. Please let me know what other documentation or information you require. Thank you.

I was driving our 2021 Chevy Suburban, which had ~107,000 miles on it, at approximately 75 miles per hour. With no other indication, the low oil pressure light came on, then within two seconds I lost all power (motor shut off) and lost electronics in the car. I had to man-handle the vehicle to get it off the road without power or dash controls. Our family was stranded near the California/Nevada border with no cell reception in the middle of the night for over seven hours. I spent a fortune having the vehicle towed to a Chevy dealership (Wild West Chevrolet in Yerington, NV) where they indicated that there was a main bearing failure which caused the engine to seize. A full L87 motor replacement is required. The motor is currently on backorder with GM due to the high number of L87 engine failures. GM has not provided an estimated date of when they plan to have the motor replaced.

Jan 23, 2025

We have had several incidents of issues with the engine and electrical system. There are as follows: - NO CHECK ENGINE LIGHTS and engine failed. - Engine continues to be sluggish and hesitant. Headlights do not come on when in "auto" and it is dark outside. - Doors lock with the keys inside and the engine is off. - Keys are showing in sleep mode or not present when they are present. The engine went down on May 6, 2021 and I was on the highway with 2 of my children. I could not accelerate. There was traffic and could not keep up. I was able to get the truck to the delearship to have inspected and repair attempted. NO check engine lights.

SEAT BELTS

3 complaints

3rd row middle seat belt covers (2) detached and fell off and seat belt retracted inside roof of vehicle. I had to fish out the seatbelt and tie to a metal clip to prevent the seatbelt from retracting inside the roof again. Third row middle seat belt is not usable.

May 01, 2023

I'm writing to complain about the proposed temporary resolution of the recall. I received a letter today advising me that repair parts were unavailable and that I should simply not use the third row seats until the inspection/repairs are completed. Like many people who own Suburbans, I bought this vehicle because we are a family of six. This is the only vehicle in our home that can fit both adults and all four children. Not using the third row is simply not an option for us. This is an unacceptable solution, no matter how temporary.

Crash: 1

I was driving on the freeway about 65 mph on Saturday June 18. In a sudden instant, there was a message on my dash "brake module failure" and "speed limited to 62 mph". Also warning message that "forward collision warning was off" , etc. The ABS light, the "check brakes light", and the check engine light all were on. Also, the power brakes went completely out and to stop I had to press really hard with manual brakes. I don't think a small framed person would have been able to stop and if I had been at a moment where I needed to stop quickly I don't think I would have been able to stop had there been a need to stop quickly. The dealer tells me that the brake master cylinder failed. The car has 43,000 miles and has been well maintained.

Jun 21, 2022

While driving, I received a notice identifying a problem with the ESC system and that there was a brake system failure. I have received an advanced diagnostics alert about the antilock braking system. the vehicle was difficult to stop and required excessive pressure on the brake pedal.

POWER TRAIN,ENGINE,FUEL/PROPULSION SYSTEM

2 complaints

I have a 2021 Chevy Suburban with the L87 6.2L V8 engine. At 7k miles, we have lost propulsion, leaving the car undrivable. resulted in the dealer replacing all 16 lifters under a recognized bulletin. I never received extended 6yr 100k mile powertrain warranty as described in the bulletin. Since then, There have been 3 other issues with loss of propulsion, resulting in replacement of fuel pump modulator. belt pulley system, One of the incidents left us without power or control of our vehicle on the interstate, with no where to pull over or get out of the way of oncoming semi trucks. The last incident again left the vehicle undriveable at 84k miles, with the dealer currently reporting that it is a lifter and cam shaft issue. Resulting in a 10k bill. They state that it is not covered under the recall of these engines because it is the top of the engine versus the bottom. Clearly, the engine oil problem noted in the recall has contributed to these issues . and the crankshaft not syncing properly with the lifters.

Hi, my name is [XXX] . I have two major issues with my 2021 Chevrolet Suburban: The value body failed for the 2021 Suburban in December, causing engine power reduction and the engine transmission was not shifting properly. This was covered by my extended warranty, which I paid $2500 extra for at the time of purchase. Also, this VIN is for a Chevy Suburban Duramax Diesel. The Emissions Control Module ( ECM ) light has come on several times, starting from about 20K miles to now 61K miles. I noticed the ECM light comes on at about a 8K mile interval. I take it into the dealership and they have told me this is due to a software issue and then they reset the light. This has happened on at least 4 occasions since about 20K miles. However, now at 61K miles, they are telling me that the exhaust system has a leak and it may not be a covered repair under even my extended warranty. Basically, General Motors has kicked the can down the road on the ECM issue until it is no longer under warranty, and now they want me to pay for this expensive repair. This is wrong, I hope you can protect me and other Duramax owners from GM's unscrupulous business practices. You can reach me at [XXX] for more details. Thank you, I am considering legal action against GM for this issue. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving and then the vehicle started running rough. There was no indication or warning lights before this happened. This is a huge safety issue because I could have had a wreck and injured people and my very own family. I took it to a Chevy dealership. They inspected the suburban and number 4 cylinder had a pool of oil in it. And they told me it need a new engine. Which it has the L87 engine that all the GM recalls are on. However, they are telling me mine isn't on the recall. They don't know if GM is going to cover it because it has 111,000 miles and it's out of the power train. It's the same engine they're having trouble with engines failures on. And I believe mine should be under the recall.

Purchased the new 2021 Chevrolet Suburban, 4 miles on odometer and left the dealer. Less than 20 minutes from dealer AC stopped working. Called dealer thinking it was small error. While on phone I looked under the vehicle which was now emitting foul burning odors. Noticed a very large amount of oil(1quart+) dripping from everywhere from engine to exhaust mid way down vehicle,oil cooler line was blown off. Towed newvehicle to dealer. Chevrolet wants me to keep this vehicle even though there was a TSB issued last year about this same issue. Chevrolet was supposed to fix before shipping vehicle and demanded dealers to do the same but did not follow its own advice. Now they want me the consumer to take a vehicle that now has 17 miles on it that has been repaired even though the issue was supposed to be remedied by manufacturer. GM/Chevrolet considers this a new vehicle even after major service for a known issue and wants me to marry this vehicle for 6 years of payments. I put down $22500 cash and this is the slap I get as consumer!

ELECTRICAL SYSTEM

After a major HVAC repair involving the evaporator core (performed at a Chevrolet dealership), my vehicle began experiencing serious electrical issues. The second-row 12V outlet no longer functions, and the vehicle has gone completely dead three times while the engine was off due to the auto stop/start system — once while stationary on a major highway, creating a dangerous situation. Each time, the engine failed to restart automatically, and the entire electrical system became unresponsive.

This evening while driving the windshield wipers started (while the wipers were in the off position). When using the turning signal it speeds up to approximately 3 times the normal speed. The display says the back hatch is open and the cargo light is on (the back hatch is closed). We turned off the car multiple times and the conditions persist.

For the past 2 years my windshield wipers will fail randomly while using them during a rain storm. I will have to pull over and completely turn the vehicle off turn back on and they may start working again or restart a couple more times. I’ve taken it to the dealership twice over it and the one time it was when they didn’t work and no codes showed up. It just happened again while on the turnpike during a rain storm. It’s very scary because some roads you can’t pull over right away and It’s very hard to see when the windshield is completely covered and the wipers won’t work. A major safety issue. I wanted to take a video but it’s not safe when I’m driving and trying to see out the window. I have 2 little kids and currently pregnant so this is very scary with my kids in the car.

Yesterday marked the 2nd time that the front windshield wipers on my 2021 Chevy Suburban (58k miles) randomly stopped working while driving down the highway in a rainstorm. They would not come out of the resting position regardless on what setting they were put to on the wheel switch. They continued to not work for the hour drive back to my house. The last time this happened all fuses, motor, etc were checked and tested good. The wipers started working again a day or so later, using the windshield wiper fluid button to test. This marks the second time my family has been put in a situation driving on the highway in a rainstorm with the wipers randomly stopping to work and having to navigate to safety with extremely limited visibility. This appears to be a fairly common issue with newer GM vehicles with the auto sense technology, found plenty of forums with the same experience. The major concern I have is that when this happens the wipers don’t work at all in any mode. Even trying to run in manual mode rather than auto sense the wipers will not move from the resting position. It leaves a driver with zero way to clear rain and see when this randomly occurs.

The 22 inch rims on my vehicle are cast aluminum I'm assuming. I have had several cracks causing me to rapidly loose air on the tires while driving at highway speeds. I have had three cracks in different rims within the last week and have had the rims repaired twice. The vehicle has 75k miles on it. This is a major concern and safety issue. I've never seen that many cracks happen at once. Some say well your hitting potholes but that isn't the case here.

Oct 19, 2024

Rims keep cracking on the inside where the tire is sealed. This has happen a total of three times to both front and rear passenger side. Tire pressures are 36psi as recommended by manufacturer. No major pot holes or other road hazards have been hit.

Service safety restraint constantly reappears. Taken into dealership 3 times and still has not been fixed. This could cause serious injury or harm and I have 4 children 10 and younger. This has been an on going problem.

A warning message appeared on my 2021 Chevy Suburban dashboard that says "Service Safety Restraint System". This impacts the airbag control module under the driver seat. After doing some research on my own this is a TSB PIT5759 but it is not covered under a recall, as per my local dealership. I took the vehicle to the Chevy dealership where purchased and was told this is not a recall or warranty part. This is very disappointing as it impacts the airbag controls which in an accident could cause severe injury or death.

FORWARD COLLISION AVOIDANCE

2 complaints

The contact owns a 2021 Chevrolet Suburban. The contact stated while driving at an undisclosed speed, the Forward Collision Avoidance system activated and abruptly applied the brakes, dramatically reducing the speed of the vehicle. Later, the contact stated that while driving at an undisclosed speed with the Adaptive Cruise Control activated, the vehicle inadvertently accelerated, requiring the contact to depress the brake pedal to avoid a collision. The vehicle returned to normal functionality, but the failure became a regular occurrence. The Forward Collision Avoidance warning light was illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the Forward Collision Avoidance warning light and the Adaptive Cruise Control module. The vehicle was repaired, but the failure reoccurred. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 28,000.

We were traveling approximately 30 mph approaching an intersection of a 5 lane road. A vehicle in front t of us had pulled into the turn lane. As we approached the vehicle that was already completely in the other lane, our car suddenly braked to a complete stop even though my foot was only on the accelerator as it is a 40 mph speed zone.

Originally we had an engine light come on upon the engine chugging and the vehicle lunging forward at times. The diagnostic showed a bad lifter on the passenger side. They then replaced the passenger side lifters. We asked them to replace both sides since this was a known problem with our year, make, and model. They said they weren't replacing both sides of the lifters. Luckily we were still under the warranty for this repair. Now, a little over a year later on the day we were taking it to trade in, the engine light came on and the engine started chugging again. I knew immediately what the problem was. I took it to the same dealership and they quickly diagnosed it with a lifter failure on the driver side. Unfortunately we are out of warranty at 80,200 miles. The vehicle is only 2 years old. We have been advised not to drive the vehicle until it is repaired. I should not be responsible for the cost of the repair when this is obviously a known defect with the lifters for my year, make, and model. They should have replaced all lifters when the vehicle was originally brought in for the passenger side lifter failure. This should already be a recall by GM for the amount of vehicles that have and will experience this lifter failure. There is actually a class action lawsuit filed against GM for the lifter failure.

Came to a stoplight and the car came to a stop. The car then automatically shifted into park on its own. The car would not shift out of park an the engine would not start. The car just died. Police showed up as I was in the middle of traffic and no one could even get the car to shift into neutral to push it out of the road. Very dangerous situation. Tow truck came and they could not even get the car in neutral. So they had to drag the car onto a flat bed. Dealer has examined the car. The starter was bad, the fuse box was bad but the major issue was in the engine where the lifters went out. To have the lifters go out at less than miles is unacceptable. The dealer commented that they are seeing this issue constantly from 2021 Chevy SUVs. This is a major safety issue in that there is no was to put my 2021 suburban in neutral when this happens to clear the vehicle from a busy highway. Please investigate this.

I was driving when I received messages saying service ESC, Forward collision System Unavailable, & Service Traction Control. The vehicle began to shake hard when I applied brakes, had loss of power when pressing the gas pedal, and sounded like metal grinding. All of this put my children & I at risk as we were on interstate 35 with cars flying past us and I’m losing power. Initially the spark plugs and coil was were changed to no repair. It was towed to a dealership where they confirmed the lifter & cam failed which put metal in the oil. My only option is a full engine replacement costing 20k on a vehicle that’s 4yrs old. It’s not ok that I have to spend that in order to get my 70k car drivable. Im now without a car, still paying a car note, unable to get my kids places, and having to get help from friends all bc GM can’t build a quality vehicle. I also haven’t been able to get a loaner car. This isn’t happening in only the 6.3L. This is a widely known issue with the 5.3L as well. *There were ZERO warning signs that something was wrong. Drive just fine that morning*

SUSPENSION

I bought the vehicle on January 11, 2025. Within 2 weeks the service leveling system indicator light came on the dashboard. The vehicle's front left air suspension system was not working properly and the vehicle lowered to the crash shield. The vehicle would not go over 55 miles and hour and was bouncing all over the road. The vehicle went back to the dealership and they reset and calibrated it. A few weeks later, the same thing happened. The vehicle again went down in the front, and was unsafe to drive. The dealership had the vehicle for 3 weeks, had difficulty assessing the situation and changed the front left air suspension arm. They told us it was fixed. We picked it up and as we were driving it home the service leveling system indicator came on, we brought it right back. They had the vehicle another 2 weeks and changed the solonoids, reset and recalibrated and had us pick it up. Within a few weeks the same thing happened, but worse. As I was driving it, an explosion sounded from the vehicle and the whole entire front of the vehicle lowered to the crash shield, making it extremely unsafe to drive. I have asked for the dealership to get a certified mechanic from GM to come and look at the vehicle and to start the repurchase process, no one is getting back to us and the vehicle is unsafe to drive.

I was sold a vehicle from a dealership in Green Bay Wisconsin under the impression all safety regulations were met. The day I drove it off the lot, I had issues with the back drivers' door, making wind noise. I had messaged the salesman, he stated it may have been the door seal. Days went by, it wasn't sitting well with me, I made an appointment with a local body shop in. regard's to the door and suspicion of something not right. I brought it to the body shop, they informed me, that the back air bags were deployed and stuffed back into the roof, body work on the left side was done incorrectly and is very unsafe to drive, seat belts where my children sit were finger tightened, frame is held on by a bolt etc. The body shop states that if this vehicle were to be in an accident, it would not sustain impact the way vehicles are designed to do so. The owner of the dealership I had bought from refuses to come to an agreement about this situation. I have all the paperwork and documents from the body shop along with another local dealership near me who I also brought it to look it over as well so the owner could understand that this vehicle should have never been able to be sold on his lot. They also agree that this is super unsafe and should not be driven until it is fixed properly and all safety standards should be met. They believe that it should have been totaled out, it is very obvious that the left side was hit and smashed in. I also asked the owner if he would feel safe for his children to drive in this vehicle and he said, “no” I have many documents/pictures/reports to share once needed.

Seat, mirror, steering column pre-set driver adjustments do not come into proper driving configuration on a regular basis when starting vehicle. This is a dangerous situation when a malfunction does occur. Seat has tendency to squeeze driver torso into steering column and knees into dash. LH mirror inadvertently and unexpectedly tilts down toward the ground and ofter unnoticed. This makes for a dangerous condition where the driver assumes that there is no oncoming rear traffic and it's safe to pull away from a curb from a stopped position. This condition has occurred for over a year and while the vehicle was covered under factory warranty. Numerous trips to Bonner Chevrolet in Kingston service department for remedy have yielded nothing. Bonner Chevrolet walked away from this serious issue and told us there's nothing more they can do and said, sorry. In contact with Chevrolet through Chat messaging, the recommend other surrounding dealers. None are interested at this point. the chat messaging is as useless as Bonner Chevrolet. Meanwhile I'm driving and paying for a useless and dangerous vehicle which no one knows how to repair. This has been an ongoing event since June, 2023.

Since I couldn’t start my car I could not put it in neutral to move the vehicle out of 2 way traffic. We want the issue confirmed by the dealership but the police who aided me and my children inspected the vehicle and recommend getting the fuel pump look at. No warnings were displayed.

The computer component surged, and the vehicle is available for inspection. The vehicle brake function is lost. Stepping on the brake paddle did not apply brake. Brake function was disabled by the computer. I took the vehicle to dealer, they said it was a component that has high resistance that cause it. But not sure why it has high resistance at that time and the resistance is gone after driver restarted the vehicle. No one else inspected the component beside the dealership. There was no warning at all and this is the first time it happens. Driver was just driving normally and suddenly all the light in the instructment panel started blinking and driver tried to apply brake but nothing happen. Luckly it wasn't rush hour, and driver was able to let the vehicle roll to the freeway exit on ram and use the up ram to slow the vehicle until it almost stop and changed gear to Park to stop the vehicle. Driver then restarted the vehicle and the problem is gone.

I have had to the dealer multiple times, several repairs, told it is safe to keep driving by GM. The inverter is bad and told me it was ok to drive until they can repair. GM will not give me a fair response or answer. The dealership won't buyback, and offered to purchase for nearly 30k less than I bought it for 18 months ago brand new.

With cruise control activated, at least 10 times since I bought this expensive vehicle the automated emergency braking activated at highway speeds - causing the vehicle to full brake without warning and nearly causing an accident each time (handling risk and risk of being impacted from behind by a following vehicle). I have formally reported this issue to dealers in MN and MT, and they only thing they said was they could not duplicate the condition during brief test rides and this was not a know problem. I personally know this was a known problem and GM did a safety recall for this condition on MY15-20 Suburbans. This condition is definitely an unreasonable risk to motor vehicle safety. In additional, the original tires supplied by GM (Firestone) failed under normal driving conditions after only about 35,000 miles, and both GM and Firestone denied there was any warranty coverage. Since then, new Les Schwab tires failed at about the same mileage. Something is obviously not right with this vehicle, and this condition is also an unreasonable risk to motor vehicle safety. Finally, last week my front passenger wheel cracked. I have not hit anything significantly hard with that wheel - but it is nonetheless cracked. This is also obviously defective and an unreasonable risk to motor vehicle safety.

Car suddenly swerved, loud knocking started. Multiple system failures started flashing. Forward collision, ECS, traction control, the car was vibrating, jerky. I have multiple videos as well. The dealership literally told me they’d seen a ton of these when I called immediately and then told me to keep driving because the damage was done and if the engine died well then it’s under warranty. I have 3 children under 5 and that is NOT an appropriate answer when I asked about it being safe to drive considering it’s jerky/shaking/knocking, and has multiple systems down. I’ve also googled and joined forums and this is apparently a common issue in the 2021 V8s and Chevy refuses to issue a recall. Would be more than happy to provide videos as well it won’t let me upload them with the photos. Was told it could be weeks before they even have parts
