I took my 2024 Chevrolet Suburban to get repairs associated with GM safety recall N252494000 - L87 Engine Loss of Propulsion. My vehicle "passed" the test, so the "correction" employed by GM is that "vehicles that pass inspection will be provided a higher viscosity oil, which will also require a new oil fill cap, an oil filer replacement, and an owner's manual insert." All of this was done free of charge. However, the owner's manual insert states that "For future engine oil changes, use SAE OW 40" oil. This updated owner's manual insert, which is provided as a solution to GM's recall of a faulty connecting road and/or crankshaft, causes the future costs of oil changes to increase from $160.00 to $230.00. Assuming quarterly oil changes, this will increase the cost of operating this vehicle to increase by $2,800 over an estimated 10 year lifespan. This increase should be covered by GM. GM sent me a letter that states, "If your dealer fails or is unable to remedy this defect without charge, or within a reasonable amount of time, you may submit a written complaint to the Administrator, NHTSA." By passing on the cost of the increase in oil change for all future oil changes, GM failed to remedy this defect without charge. I submit this claim because GM filed to remedy this defect without charge. Please see highlighted portions of attached documents in support.

I managed to coast into a parking lot. The engine light was on. I turned the vehicle off and waited about 5 minutes and turned it back on, The engine light remained. The first time this happened I was going down the road and the vehicle started sputtering, the emergency brake light came on the dash and the car shut off. It has a rough idle when you start it. I am terrified of this car. I have grandbabies in the car with me, Had i been on the highway either time i would have caused a terrible accident. The dealer says they can't get the car to do it so they can't fix anything. It has happened twice so you know it will again.

If I stop and turn of the vehicle and restart the rpm's will be better but the truck still seems to have a difficult time increasing in rpm's and accelerating gears. It's incredibly dangerous as if I'm driving at a substantial speed on the highway or freeway and it drops rmp's rapidly I'm likely to be in an accident which could be detrimental. The dealer has had my vehicle on two separate occassions. The most recent time they've had it for 5 days and still do not know what's wrong with it. The engine light will not turn off.

Since purchasing the vehicle on September 27, 2024, I have experienced a series of troubling issues that raise serious concerns about its design, manufacturing, and overall safety, including: Airbag system malfunction: My airbags were nonfunctional for over a month. Tire-related issues: Required full replacement of the initial set of tires. Persistent alignment problems Bluetooth audio problems: Poor quality and connectivity with multiple phones, resolved only after a service visit in May 2025. Defective seat frame: Rear passenger-side bucket seat required full replacement. Defective paint: Blisters and bubbles in the rear quarter panel paint. Fuel module failure: Most concerning, the vehicle abruptly stopped on the road last week and required towing. I was later told the cause was a fuel module failure. Each of these issues is concerning on its own. Taken together, they represent a troubling pattern of unreliability and potential risk to my safety and that of others on the road. They’ve also resulted in a significant loss of my time. This vehicle has spent over a month at the dealership for service—astounding for a truck that’s only eight months old. These are the kinds of delays and disruptions I specifically try to avoid by purchasing and maintaining new Chevrolet vehicles.

I was entering the interstate, at 65 miles per hour, and went to set the cruise once I reached 70mph, and noticed that I was losing power, the engine had stopped and we dangerously lost speed on a interstate where folks were traveling north of 75-80 mph. I costed to the shoulder and tried to reset with no luck. We called Onstar and had it towed to Hendrick or Monroe NC. We found out that this was an engine failure and the long block had to be replaced. This left us stranded without a car to drive to our cruise —GM told me I could buy plane tickets and they’ve never denied reimbursement. Unfortunately they denied it once I submitted all the receipts. It been a horrible experience with no help from GM.

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)

On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001. This investigation was opened to assess the remedy effectiveness of Recall 25V-274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V-274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GM’s recall remedy for Recall 25V-274 consisted of two different repairs, either an oil viscosity change or an engine replacement, based on the results of the remedy inspection procedure. ODI continues to receive reports of engine failures after the completion of the recall remedy.
