2024 Chevrolet Suburban

Upon stepping on brakes, the car shifts into Neutral and says “press start Button again.” This happened to me 2x now.

Complete and sudden failure of the L87 V8 engine at 70 mph on the highway. Had to maneuver to the right shoulder and coast to a stop. Engine was seized and would not restart. Waited 4 hours on a dangerous highway for a tow truck which took the Chevy Suburban 200 miles to my home Chevrolet dealership. They have ordered a new engine but it is on backorder so no ETA. Vehicle was built 06-26-2024 and has not been recalled so Chevy says I do not get the extended warranty on the replacement engine.

The vehicle went into limp mode! Everything associated with it happened so quickly,no brakes,no steering ,it was terrifying. We got safely to a gas station. We were advised to take it to a certified Chevrolet dealer which we did We had it towed to the certified Chevrolet dealer in Charlevoix, Michigan.They hooked it up to the diagnostics and said they found absolutely nothing wrong with the vehicle.Very Frustrating! After experiencing this terrible incident will never feel safe in this vehicle!

Both front CV axles have had to be replaced multiple times. Less than 70,000 miles on the vehicle.

Sudden power loss on highway. Engine would not respond. We were fortunate to have been able to pull over to the side of the road but in an unsafe merging area. Vehicle restarted after multiple attempts, but engine would not exceed 3000 rpm causing unsafe speed on highway. Engine died again causing total power loss. I was able to coast down the hill to safely park out of the way of traffic. Tow truck was needed. Vehicle was towed to dealer where it was purchased. After inspection, the engine was confirmed to have failed. The dealer advised for engine replacement as part of the L87 recall. This engine was previously inspected less than 10,000 miles prior as part of the same recall, and the higher-weight oil had been used since per the manufacturer's recommendation. However the inspected engine appears to have failed regardless. This sudden loss of power happened about two weeks prior, with the driver able to pull to safety and restart. It was dismissed as a fluke since it did not occur for the next two weeks.

i pulled on to the road and i heard a loud knocking and my vehicle started skipping and wouldn't go. the lights on the dash lit up and said, "brake failure" and "emergency brake failure" and i had no brakes. 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.

The vehicle was previously repaired under NHTSA Campaign Number: 25V274000 (ENGINE AND ENGINE COOLING); however, the failure persisted. The local dealer was contacted; however, the vehicle was not repaired. The manufacture was not notified of the failure. The failure mileage was 27,300.

The vehicle only has ~39,000 miles on it and the transmission went out and the car is not drivable. The dealership said it is a faulty valve body and that the part is on national back order and could take 2 to 6 months or even longer to get the part before they can start work.

The engine light comes on and then the rpm's drop to 35 and a notification comes up that says "reduced acceleration. driving with caution". 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.

I have had my cruise control set and my car will slam on the brakes with no vehicles in front of my car or on each side. This has happened multiple times, it doesn’t matter if I am going 40MPH or 60+MPH. I have taken it in and they say there is nothing they can do for the issue. I’m worried for the safety of myself, my family, and my unborn child. As well as any cars around (behind me potentially) when this happens. I do not want to unintentionally cause an accident.

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 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.
