2024 Chevrolet Suburban owner complaints

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 pers

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 veh

Driving our 2024 Suburban, 6.2 L engine, on a 2-lane highway in southern Utah, traveling on cruise control at 70 mph, felt 2 hesitations (jerking movement), and turned off cruise control. Immediately after, heard knocking/thumping sound in the front of the vehicle, followed by a whining sound that got louder. Immediately found a turn-off from the highway, pulled in, and engine died while vehicle was still in motion. Attempted starting again and would not start. People stopped to help us and tried to jump vehicle without success. Suburban was towed to a Chevy dealership and we were told the Suburban's engine seized. In researching this issue, we came across NHTSA's investigation case EA26005. Our VIN does not fall in to this recall.

While driving down a two-lane blacktop road at 70 MPH (the posted speed limit) the engine, a 6.2 L L87 with a little over 15,000 miles, grenaded and seized. At the time I recall a warning message that said something like "engine shutdown". Fortunately the electronic transmission self-shifted into neutral so the car could coast to a stop. Had it not done this a loss of control would have been likely at this speed. The vehicle was towed to the local Chevrolet dealer in Bozeman, Montana (Resseler Chevrolet) where it was confirmed the next day the engine had seized. The dealer is currently replacing the seized engine with a replacement long block. The dealership currently has the engine and is planning to ship it back to Chevrolet or GM for tear down and inspection. They are also replaci

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.

Persistent, intermittent total audio cutout disabling critical crash avoidance alerts. Failure Summary & Safety Impact: The vehicle experiences intermittent, complete failures of the audio system across all sources. When this failure occurs, all audible safety warning chimes are completely silenced—including Forward Collision Alert, Front Pedestrian Braking, Lane Departure Warning, and Park Assist. This places occupants and other road users at immediate safety risk, as the driver receives no audible warning prior to an impending crash or hazard. Diagnostics & History: The issue first was brought to an authorized Chevrolet dealership for inspection and repair multiple times (first on April 29, 2026) and has not been remedied. They even replaced the radio system (through which all audio

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.

Subject: Formal Safety Complaint—Cracked 22-Inch Polished Aluminum Wheels on 2024 Chevrolet Suburban To Whom It May Concern: I am submitting a formal complaint concerning repeated failures of the original 22-inch polished aluminum wheels installed on my 2024 Chevrolet Suburban, which I purchased new. Two wheels have cracked without any known impact, collision, road-hazard event, or other incident that would reasonably explain the damage. The first wheel cracked at approximately 25,000 miles. Tire pressure began dropping unexpectedly and ultimately fell to zero. The wheel was inspected and replaced by a dealership in Cincinnati. A second wheel later cracked and caused another sudden loss of tire pressure without warning. During that incident, I experienced difficulty maintaining steering
