ENGINE, POWER TRAIN
On[XXX], at approximately [XXX], while driving on [XXX] at a speed of 80 mph, my vehicle suddenly lost all power and shut down without warning. I had no choice but to steer to the shoulder lane amidst high-speed traffic on the busy interstate. After coming to a stop, the car would not restart, leaving me stranded in a highly precarious situation. As the weather conditions worsened, turning into a blizzard, and darkness set in, I contacted GM Roadside Assistance for help. I was informed that assistance would take at least an hour to arrive. Feeling unsafe, I called local law enforcement. The officers arrived and parked behind my vehicle with their flashers on to ensure approaching drivers would slow down and avoid an accident. This was an extremely distressing and frightening experience. After an hour, GM Roadside Assistance called back and informed me they were unable to find an operator to tow the vehicle. By this time, the officers on-site had contacted a local tow company for my safety. The tow company advised me that I would need to pay in cash for their services, which I accepted due to the urgency of the situation. They towed the vehicle from [XXX] to their yard in Douglas, Wyoming. I then arranged for a ride to Cheyenne, Wyoming, where I had to report to work that night. This incident not only jeopardized my safety but also left me with significant unexpected expenses and inconvenience, all due to what I believe is a manufacturing defect in the vehicle. A new vehicle should not experience such catastrophic failure, and the delayed response from GM Roadside Assistance compounded the problem. I respectfully request the following actions 1. A thorough investigation into the root cause of the sudden failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Loud ticking noise coming from the engine bay and extreme shaking. All happened after dropping off clients and getting on the highway on September 5, 2023. Took vehicle to two different mechanics and they said the camshaft and lifters had to be replaced. They recommended it would be cheaper and better if I replace the whole engine, which I did and had to pay out of pocket.

ENGINE, ELECTRICAL SYSTEM
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.

On April 7th 2024 we were traveling on vacation 2 1/2 hours from home and our vehicle started making a ticking noise and traction control, engine light, service emissions, and front collision warning all came on. It was idling very rough. We had to stop for the night with our kids and take it to the closest dealer the next morning. They diagnosed the car and confirmed that the lifters needed repair. We had to leave our vehicle and get a rental to make it back home. The dealer made repairs and sent vehicle back to us. Fast forward to 1/15/25 I was on the way to work and the same thing started happening. I then had to tow the vehicle to the dealership and they have diagnosed it with the same issue on the other side of the engine. As a brand new vehicle this should not be happening. Each time we were stranded with kids and without a vehicle for a long period of time.

The lifters failed in April 2024 and was replaced by the GM dealer and then the engine failed again in September 2024 however I couldn't afford to pay GM $2000 for a diagnostic and they still have my vehicle and only offer me $1500 off of a new or unused vehicle.

The dealer stated the 6.2L engine had a bearing failure. When driving on 12-24-24 to a family event the dash lights all lit up and the car shut off. I was barely able to put the Suburban into neutral to pull off to the side of the road. Once stopped, the Suburban wouldn't start or even go into neutral so I could push it further off the side. This is extremely dangerous. My entire family was in the car on a very busy day (Xmas eve) without the ability to move the car in any way. Even when the tow truck driver arrived, he stated there isn't a way to force it into neutral. I also first learned about the 6.2L bearing issue from him. His 2023 Suburban was in the shop for the exact same issue. My 2024 Suburban has less than 13,000 miles on it before the failure!

At a stop light the stabilitrack and check engine light came on. Engine began running very rough. I pulled around the corner and was able to get into a parking lot. When I stopped the vehicle the car shutoff completely, including all the electrical. I tried to start the car but when I did there was no engagement of the starter and all electrical shut off again. Car was towed to a mechanic shop and was advised that the engine was seized after they could not turn the engine using manual means. I had to have the engine replaced.

SERVICE BRAKES
On October 23, 2024, my 2016 Chevrolet Suburban was stopped in a line of traffic on a downhill. As traffic began to move forward, the brakes failed to hold, despite pressure on the brake pedal. This resulted in a low-speed collision with the vehicle in front, which then impacted another vehicle. Component/System: The braking system failed to engage despite pressure on the brake pedal. The vehicle is a total loss; however, documentation of the damage is available through my insurance company, New Jersey Manufacturers, claim number 2024-884575, and the police report from the accident scene. Safety Risk: This brake failure posed a significant safety risk to my family (who were occupants), and other drivers. The collision caused substantial vehicle damage. Confirmation: The vehicle has not been inspected by a dealer or independent service center due to it being a total loss. It has been inspected by my insurance company. Inspection: The vehicle has been inspected by police at the accident scene and by my insurance company. Warnings: There were no prior warning lamps, messages, or symptoms of brake problems. The vehicle has been consistently maintained by All American Chevrolet with all recommended services performed. This incident raises serious concerns about the vehicle's braking system integrity, especially given its consistent professional maintenance. I request an investigation into this matter.

While driving my family home from our christmas vacation on the Garden State Parkway (NJ) the engine shut off and would not restart. This happened on a stretch of the highway with no shoulder while traveling at 65mph. Thankfully we were able to coast far enough to a section of highway with a shoulder. This incident left my [XXX] , [XXX] , my wife and I and our dog stranded in the freezing cold 100 miles from home. After a stressful next few days the Chevrolet dealership diagnosed it as blown bearings in the motor. It has now been over three weeks and no word from GM when a new motor will be available.

When traveling at highway speeds our vehicle suddenly lost all engine power. Driving in the passing lane of [XXX] at 75 mph our 2023 Chevrolet suburban RST 6.2 lost all engine power and went into neutral. We were barely able to make it over to the right breakdown lane without getting hit and making it with no power. We were stranded on the busy interstate for three hours with my wife and three young kids in a very dangerous location. They were scared and because we barely made it into the breakdown lane and so close to speeding traffic had to stand outside of the vehicle close to the woods further from dangerous traffic. The Suburban was flatbedded to nearest Chevrolet dealer where we were told the engine was seized and would need to be totally replaced. We were lucky to be alive but now stranded 1000 miles away from home as we were returning from a vacation in Florida. The sudden lose of all engine power traveling on the highway with our entire family was both scary and dangerous. The suburban has now been in the shop for three weeks with no date in sight to be ready and 1000 miles away. This was a truly dangerous situation and thankfully we came out unscathed but I fear someone else may experience the same type of failure and not be so lucky.

Driving at 65MPH on a three-lane highway with heavy traffic, there was a sudden loss of motive power without any prior warning. As the motive loss occurred, the check engine repair light illuminated. I immediately illuminated my hazard lights. Luckily I had enough momentum to safely glide the vehicle over three lanes to the breakdown lane. I was fortunate that other vehicles gave way to me or that I was not on an incline, otherwise the vehicle would have been stopped in the middle of the highway. After repeated attempts, the vehicle would not restart and had to be towed to a dealership. The dealership confirmed the problem and repair was covered under warranty.

POWER TRAIN, FUEL/PROPULSION SYSTEM, ENGINE
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)

On January 1st driving east bound on road 520 in central florida. I was driving around 65mph when the vehicle suddenly shut off. The displayed showed a warning saying that something of the sort that I needed to press the brake to start the engine even though I was driving normally. I had to coast to the side of the road and I pressed the brake. once the brake was engaged the vehicle immediately went to park and will not start. I press the ingition button and the screen would go blank and no sound or warnings were displayed. I had to call the police to provide a safety as the vehicle was in a very dangerous area and all my family was on the vehicle. the police laid down flares and I contacted a tow truck using onstar. Onstar was unable to communicate with the vehicle to diagnosed the issue and no warnings or errors were displaying. The vehicle was towed to Carl Black Chevrolet of Orlando Florida. The dealer stated that the engine is locked (L87) and was not able to turn, therefore the vehicle does not start. The dealership technicians have informed that the vehicle needs a new engine and GM needs to approved, the vehicle is still under warranty and I've contact GM and until today, 17 days later, GM has not responded or allowed the dealership to fix my vehicle.
