I parked at my home, approximately 5 minutes after arriving home my grandson ran in yelling papa your car is on fire. The engine was on fire, shooting flames onto the windsheild. The cause of fire is unknown at this time.
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. …
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. …
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. …
On May 2, 2026, while the vehicle was in operation, the engine suddenly shut off without warning. At the time of failure, the instrument panel remained illuminated; however, the vehicle would not restart. In an effort to resolve the issue, the battery was replaced, but this did not correct the problem. The vehicle was then towed to a local Chevrolet dealership for further inspection and diagnosis. Following their assessment, I was informed by the dealership's service department that the engine had seized and that metal debris was present in the engine oil, indicating significant internal engine failure. I was further advised that a replacement engine has been ordered. At no point prior to this incident were there any warning indicators, abnormal noises, or performance issues that would have suggested an impending engine failure. …
While driving in the left lane of a two lane highway at highway speed of approx 65-70 mph the engine shut down. The instrument cluster said to "Press button to start engine". I had no power. There was no throttle response. Luckily I was on a slight decline and was able to safely change lanes by coasting into the right lane then the shoulder. I was able to put the vehicle into park. The vehicle did restart. I took the vehicle to a Chevrolet dealer and was immediately told that there was an internal engine failure. I could have been rear ended or worse. This is a very serious issue. Upon doing some research, I found that the same thing has happened to many other people. This is very dangerous. Apparently this is becoming a major issue for the GM 6.2l eco tec engine. I hope that the next person this happens to doesn't freak out and have an accident. …
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.
