general problems of the 2024 Chevrolet Suburban

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. The sudden nature of this incident raises concerns regarding the cause of failure and whether it may be related to a defect or internal mechanical issue.

The vehicle would jerk when changing gears and would have a rattle and vibration when accelerating.

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!.

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.

The contact owns a 2024 Chevrolet Suburban. The contact stated that while depressing the accelerator pedal, there was a loud rattling sound coming from the engine. The contact stated that while depressing the brake pedal, the vehicle failed to respond as intended while driving with her grandchildren inside the vehicle. The brake failure warning light was illuminated. The contact stated that the vehicle lost power and coasted and slowed down, and the contact shifted into park(p). The contact stated that the failure had occurred on two separate occasions. A dealer was contacted. The vehicle was taken to a dealer, where it was diagnosed; however, the diagnostic result was unknown. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 16,600.

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 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.

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.

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.

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).

6. 2l engine failure at 9600 miles.

The dealer stated the 6. 2l engine had a bearing failure. When driving on 12-24-24 to a family event the dash lights all lit up and the car shut off. I was barely able to put the Suburban into neutral to pull off to the side of the road. Once stopped, the Suburban wouldn't start or even go into neutral so I could push it further off the side. This is extremely dangerous. My entire family was in the car on a very busy day (xmas eve) without the ability to move the car in any way. Even when the tow truck driver arrived, he stated there isn't a way to force it into neutral. I also first learned about the 6. 2l bearing issue from him. His 2023 Suburban was in the shop for the exact same issue. My 2024 Suburban has less than 13,000 miles on it before the 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. If this happens to the wrong person, someone is going to lose their life.

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.
