STRUCTURE:BODY, FUEL/PROPULSION SYSTEM
I was driving down the road at roughly 30 mph when my fuel tank dropped. The front fuel tank strap fell off and the bolt was gone. The fuel tank drug on the road, which prompted me to stop driving. There are scrapes on the front of the fuel tank and the strap was bent. This is a huge safety concern because had the fuel tank cracked or fell off completely this could have caused a fire. Had we been traveling at higher speeds, this could have been a very serious accident. The potential for gasoline or diesel to ignite was absolutely present. It could cause a fire or even an explosion, potentially injuring occupants and causing damage to the vehicle. I was travelling with my kids and mom, so the risk of injury to multiple people was present. The manufacturers only response so far is that it was not an open recall issue so it is not covered. No warning lights came on when this happened.

FUEL/PROPULSION SYSTEM
Engine lost power and stalled without warning while driving down the highway. Coasted to side of road and was unable to restart engine. After engine stopped, dash indicated low fuel, although tank was 3/4 full. After coming to a stop, was unable to shift out of Park (which could have been a major issue if I had not been able to clear the highway before coming to a stop). Towed vehicle to closest Chevrolet dealer, who replaced the fuel pump control module. Dealer indicated that this is a common failure item to the point that they stock the part and suspected what the failure was based on my description. When pressed, the dealer representative also noted that GM has not updated or redesigned the factory installed fuel pump control module ("the new module installed is exactly the same as the one that failed"). Fortunately, traffic was light and I was able to pull to the side of road. This would be extremely dangerous if it happened while driving on a multi-lane expressway and we were trapped at a stop in heavy, fast moving traffic.

ENGINE AND ENGINE COOLING
The contact owns a 2021 Chevrolet Suburban. The contact stated that while his wife was driving at undisclosed speeds, there was an abnormally loud banging sound coming from the engine compartment. The contact stated that the failure was related to NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). There were no warning lights illuminated. The vehicle was taken to the local dealer where it was diagnosed and determined that the rods were bent, and the lifters needed to be replaced. The vehicle was repaired. The manufacturer was not contacted. The contact called the warranty company, who confirmed there was no repair coverage on the vehicle for the failure. The failure mileage was approximately 109,069.

SEAT BELTS
The rear seatbelt in my 2022 Chevrolet Suburban RST became dangerously tight around my daughter's waist while she was lying down in the seat. The belt would not release despite multiple attempts. She was hanging off the seat and in distress, and I was forced to cut the belt to prevent injury. This raises serious concerns about the seatbelt retraction mechanism. I request a formal investigation.

POWER TRAIN
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.

Since that day we also received numerous warning light which include. Driver window. Esc. Winshield fluid. Tire pressure. Lift gate open. Forward Collision System Unavailable. Your 2021 Chevrolet Suburban detects a battery, starter or connection issue. Lastly the check engine light came on and the car won’t start.

ELECTRICAL SYSTEM, ENGINE
While driving on the highway at 55 mph during a long-distance trip, the engine of my 2022 Chevrolet Suburban (6.2L V8) failed suddenly without any warning lights, messages, or prior symptoms. The vehicle lost power unexpectedly, creating an extremely dangerous situation. I was traveling to a national wheelchair basketball tournament and had a passenger in the vehicle at the time. Our safety was immediately at risk due to the abrupt loss of power in a high-speed traffic environment. The vehicle was towed to the dealership, where the issue was confirmed as a complete engine failure. The dealership later replaced the engine under warranty. I was informed that the engine installed was the same model currently under active recall (N252494001), which affects the 6.2L V8 engine in this vehicle type due to defective crankshaft or connecting rod components. The failed engine is no longer available for inspection, but the dealership should have records of the inspection and replacement. There were no warning lamps, error codes, or drivability issues prior to the failure. The malfunction was immediate and severe.

ENGINE, ELECTRICAL SYSTEM
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.

ENGINE
My 2021 Chevy Suburban Premier suffered a sudden internal engine failure due to collapsed lifters and a damaged camshaft. The vehicle began experiencing performance issues, including rough idling and loss of power. After taking it to a certified mechanic, it was confirmed that the lifters failed and caused significant damage to the camshaft, requiring a major repair that I had to pay for out of pocket. This issue is widely known among GM vehicles with the 5.3L and 6.2L V8 engines and has been the subject of numerous technical service bulletins and customer complaints. While my vehicle is not included in the current recall (NHTSA ID: 25V-274), which covers crankshaft and rod failures on L87 6.2L engines, this lifter failure is part of the same engine family and indicative of a broader defect in GM’s V8 engine platforms from 2021–2024. I’m requesting that NHTSA investigate these lifter and camshaft failures as a safety and reliability concern, and urge GM to expand the existing recall to include these known engine issues. Many customers, including myself, are incurring thousands of dollars in repair costs for problems that are clearly tied to manufacturer defects.
