The contact owns a 2021 Chevrolet Suburban. The contact stated that while driving on the highway, the vehicle experienced reduced engine power and failed to exceed 30 MPH. A message pertaining to the deceleration was displayed. The following Monday, the vehicle failed to exceed 35 MPH, and a friend followed the contact while driving to the dealer. The dealer recommended a fuel filter replacement. The contact declined the repair because the fuel filter life was at 47%; however, the dealer proceeded with the replacement. The contact provided the diagnostic trouble code to an independent mechanic, who informed the contact that the failure was associated with TSB Numbers: 20-NA-197 and 18-NA 361. The contact then advised the dealer of the TSBs, and the dealer determined that the fuel pump module and fuel tank module needed to be replaced. The vehicle was repaired. Additionally, the contact stated that the second-row passenger’s side seat belt buckle failed and was replaced under an extended warranty, although the part was previously replaced under a recall. The manufacturer was notified of the failures several times, but no assistance was provided. The failure mileage was approximately 92,709.

The fuel pump module on this vechicle failed, and there's a recall for 2021 I believe other years should be considered as well since this was a known issue as soon as we arrived at the dealership and they wanted over $400 to replace this part which is only $45.

My 2023 Chevrolet Suburban Premier is covered under GM recall 25V-274 for the 6.2L L87 engine defect (loss of propulsion from connecting rod and crankshaft failure). In XXX, the dealer notified me my vehicle required a full engine replacement under this recall. Wareing Sheridan Chevrolet in [XXX] replaced the engine, and the vehicle was out of service approximately 12 to 14 days. Approximately 6,000 miles later, on XXX, the replacement engine failed while I was driving on the interstate highway near Billings, Montana. There were no warning indicators of any kind until I suddenly lost power. Only at the moment power was lost did the check engine light come on and a low oil pressure warning appear. I was barely able to get the vehicle off the interstate before it died. I had my family in the vehicle, and losing power on the interstate with no warning created a serious risk of a crash. The vehicle had to be towed to Denny Menholt Chevrolet in Billings, MT. On June 13, 2026, the dealer confirmed the vehicle needs a second complete engine replacement under the same recall. This is the second L87 engine failure and second full engine replacement on this vehicle under recall 25V-274. No crash or injuries occurred. I have an open case with GM (#XXX).

What component or system failed or malfunctioned, and is it available for inspection upon request? The fuel delivery system has failed. Specifically, the fuel lines are leaking at the connection point on the top of the fuel tank. The vehicle and the affected components are currently available for inspection upon request. How was your safety or the safety of others put at risk? This defect poses an immediate fire and life-safety hazard. Because the fuel leaks while the vehicle is powered on, any spark or heat source could ignite the fuel tank, leading to a vehicle fire or explosion. Additionally, the cabin environment has become toxic; the concentration of gasoline vapors is so high that it causes physical illness. One of my children vomited due to the fumes. The vehicle is currently undrivable because the vapors are intoxicating and hazardous to the health of all occupants. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the leak has been inspected, reproduced, and confirmed by an independent service center. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, the vehicle has not yet been inspected by the manufacturer, law enforcement, or insurance representatives. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lamps or dashboard messages (such as a Check Engine Light) prior to or during the failure. The symptoms—specifically a strong odor of raw gasoline—first appeared four days ago. The intensity of the odor and the rate of the leak have increased significantly since the initial onset.
NHTSA complaint #11740901 — an unverified report by a vehicle owner.
Fuel line leak caused by design flaw in which line plastic fuel feed line (GM part #84200271) is installed too close to the undercarriage, causing it to rub against the frame due to vibration and wear a pinhole. This is known by gm in service bulletin Service Bulletin 17-NA-304. This is a fuel leak, that can causes significant fire danger to people, property, and nature. Eventually putting first responders at risk. Also the environmental risk of continuous leaking fuel. Luckily, I could smell it before anything bad happened. But if GM knows about this issue, it’s big enough they should do something about it and so should the NHTSA.

My 2021 Chevrolet Suburban experienced a sudden no start condition which required the vehicle to be towed for repair. A diagnostic inspection determined that both the fuel pump and the fuel pump control module had failed. I paid out of pocket for the full repair, including replacement of both components. Several months later, GM issued a safety recall for the fuel pump control module on this vehicle. I submitted a reimbursement request to GM. GM agreed to reimburse only the control module , but refused to reimburse the fuel pump, even though the pump failure was directly caused by the defective module that is now under recall. Federal recall reimbursement guidelines require manufacturers to reimburse the full cost of the remedy for the defect. In this case, the defective module caused the fuel pump to fail, making the pump replacement part of the necessary remedy. GM’s refusal to reimburse the full repair cost leaves me paying for damage caused by the recalled component. I am requesting NHTSA’s assistance in reviewing GM’s refusal to reimburse the full repair cost associated with this recall related failure.

2/24/2026 Sitting at red light, very busy road, vehicle cut off and said push to start. Vehicle would not start and would not shift out of park to push out of road. Very dangerous to be stranded in moving traffic. Had to be towed to dealer and it's still there waiting on engine replacement.

My vehicle was subject to a GM recall involving inspection of the 6.2L engine. The recall inspection was completed by an authorized GM dealership at 58,581 miles. The vehicle was cleared as passing the recall criteria and returned to me. Within fewer than 10 miles after leaving the dealership following the recall inspection, at approximately 58,590 miles, the vehicle experienced a sudden loss of propulsion while traveling at highway speed (approximately 65 mph) on a divided U.S. highway while ascending an incline. The vehicle shifted into neutral and lost engine power without warning. Steering and braking remained functional, but the vehicle lost forward motive power in the left lane of traffic. Attempts to restart the engine resulted in a loud mechanical thud, and the engine would not restart. The vehicle was towed to the dealership. The engine is now being replaced. Prior to this incident, the vehicle had previously undergone an oil consumption test related to engine concerns before the recall campaign. This failure occurred shortly after the vehicle was inspected and cleared under the recall procedure. I am reporting this due to the sudden loss of propulsion at highway speed following recall inspection and the subsequent need for complete engine replacement.

NHTSA complaint #11718829 — an unverified report by a vehicle owner.
I own a 2022 Chevrolet Suburban RST that has experienced ongoing mechanical and safety issues over several years. I first began reporting drivability concerns to General Motors and the dealership in 2023 and continued contacting them throughout 2024 and 2025. During one dealership visit, a sales advisor rode in the vehicle with me and stated they did not observe any issues, despite my continued reports. The vehicle later suffered a loss of propulsion and required a full engine replacement. The radiator and cooling components were also replaced by a Chevrolet dealership. Due to ongoing concerns for my safety, I contacted General Motors multiple times, requested an executive buyback, and asked about Lemon Law options. GM advised that the engine had been replaced and that I needed to take ownership of the vehicle. After picking up the vehicle last Wednesday, I immediately noticed a persistent sweet coolant/radiator odor inside the cabin and outside the vehicle that continued for nearly a week. I also experienced engine hesitation/stuttering when stopped at traffic lights as the auto start/stop feature reengaged. I attempted to contact GM again regarding these concerns prior to today’s incident. Today, while driving, the vehicle displayed an engine overheating warning instructing me to turn the car off immediately. I safely pulled over and shut the vehicle down and am currently stranded roadside. Given the repeated failures, history of loss of propulsion, multiple repair attempts, denied buyback requests, persistent coolant odor, drivability issues, and now overheating shortly after engine and radiator replacement, I believe this vehicle presents an ongoing safety risk and request formal investigation.

My 2021 Chevrolet Suburban stalled while driving in late September 2025 and had to be towed to a dealership. The vehicle is subject to an active fuel pump power control module safety recall that has been in effect since 2021. The vehicle was brought in specifically for repair of this issue. The work was processed under warranty, and I was charged a deductible. After learning the repair was directly related to an active safety recall, I requested reimbursement of the deductible, as recall repairs should be completed at no cost. That reimbursement request was denied. I have since been informed that the recall repair was never “completed,” and the recall still shows open in the manufacturer’s system. I am now experiencing shuddering and symptoms consistent with a potential stall recurrence. The original stall occurred while I was transporting my children, including special needs children who require regular transportation to school and therapies. The vehicle failure left us stranded at night in an unsafe area. Due to the prior stall, the unresolved recall status, and the recurrence of symptoms, I do not feel the vehicle is safe to operate.

The front of the fuel tank is hanging down and nearly dragging on the ground. This was with normal driving on a highway. No hitting bumps or aggressive off-road anything. We noticed when we heard a scraping noise going slowly over a slight incline in a driveway that it was hanging down.
NHTSA complaint #11713809 — an unverified report by a vehicle owner.
On Saturday, 11/29/25 @ 3PM, while driving on I-75 from GA to MIA, our 2022 Suburban VIN: [XXX] sudden & unexpected had a mechanical failure. Without warning, vehicle stalled/ stop while traveling at highway speed, leaving us seconds to maneuver to the side. This failure created an extremely dangerous situation that could have resulted catastrophic or fatal accident for my family. Check engine light came on (code P102A). An officer stopped to assist & arranged car to be tow which we had to pay $135 to nearest Chevrolet dealership. Since the dealership was closed, I was forced to stay an additional night in a nearby hotel and paid $106.46. The vehicle was inspected by Countryside Chevrolet, who diagnosed the issue as a failure of the fuel pump control module however I was informed that this VIN was not covered under warranty or any special coverage, despite the fact that we experienced the exact same failure on our 2021 Chevrolet Tahoe, which was covered under warranty for this same defect. I was forced to pay $708.72 for the repair. This inconsistency is unacceptable—especially considering GMs extensive history of complaints, recalls, & class action litigation involving defective fuel pump & fuel system components, which present a well-documented safety risk. I filed a complaint with GM Customer Care (Case XXX). I submitted all required receipts for repairs, towing & hotel, however GM denied my claim without providing any explanation, only stating VIN was “not covered.” Also, GM refused to provide a written justification & my request for a manager callback was ignored. No consideration was given to the safety implications of this failure. This response is unacceptable & demonstrates a failure to take responsibility for a known safety defect. Demand: Given the seriousness of this incident, the documented defect, & GM’s prior knowledge of same failures, I demand full refund of $950.18 for expenses. This situation could have ended tragically. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA
