CHEVROLET Complaints

Suburban started to have shudder at lower rpm on acceleration. I took it to the dealer and they confirmed the valve is bad. They are unsure at this time but depending on damage from the bad value my Suburban may also need a new torque convertor or transmission.

I own a 2015 Chevrolet Silverado equipped with a GM V8 engine that experienced significant engine failure symptoms consistent with known GM engine defect issues and related recall/service campaign concerns. Prior to failure, the vehicle began exhibiting abnormal engine noises, warning lights, performance issues, and symptoms indicating internal engine damage. The condition worsened and resulted in major engine failure requiring extensive repair or engine replacement. The failure created safety concerns due to the potential for sudden loss of power and loss of propulsion while driving. Based on the symptoms, model year, and engine configuration, I believe the failure may be related to known GM engine issues involving internal engine components, lifter failures, AFM/DOD system failures, bearing damage, or related defects that have been the subject of recalls, special coverage adjustments, technical service bulletins, or investigations affecting GM trucks and SUVs. I believe the vehicle should qualify for coverage, repair assistance, recall-related repairs, or special policy consideration from General Motors due to the nature of the engine failure and the known history of similar failures affecting comparable GM vehicles. I am requesting that GM review the vehicle history, diagnostics, and failure condition to determine eligibility for recall coverage, special coverage adjustment, warranty assistance, or reimbursement related to the engine failure.

The contact owns a 2023 Chevrolet Silverado 2500. The contact stated that while driving or while parked, the tailgate unintendedly opened on several occasions. The contact related the failure to the tailgate exterior touchpad switch. The dealer and the manufacturer were contacted and informed the contact that the VIN was not included in NHTSA Campaign Number: 24V060000(LATCHES/LOCKS/LINKAGES). The vehicle was not diagnosed or repaired. The failure mileage was approximately 47,000.

Odometer Fraud. The contact purchased a 2015 Chevrolet Colorado. The contact stated that they discovered a mileage discrepancy after the purchase. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 193,073. The contact began having unknown issues with the vehicle and obtained a Carfax report. The report indicated the vehicle was due for an oil change. The report indicated the mileage was 292,500. The Birmingham police department was contacted and referred him to the NHTSA hotline.

While driving my 2019 Chevrolet Silverado 1500, the brakes unexpectedly locked up and multiple warning messages appeared at the same time, including “Service ESC.” There were no warning lights, messages, or symptoms before the incident. The problem occurred without warning while the vehicle was being driven normally. The sudden brake application made the vehicle difficult to control and created a significant safety risk because it could have caused a loss of control or a collision with other vehicles. The vehicle is available for inspection. At the time of this report, the exact cause of the failure is unknown.

Car cut off in the middle of driving it entire screen goes black and disable, OnStar does not go off continues to blink green even when vehicle is disable, vehicle is not completely powering off after shut down causing the battery to drain overnight.

I was driving on freeway and went to pass a semi. The suv hesitated and had terrible turbo lag. It almost caused an accident if it hadn’t been for the truck behind me taking action to avoid a collision.

When I first got this vehicle 2019 brand new off the lot the dealership in newark ohio had to completely rewire it. It took them a month to figure it out. I just replaced the transmission and now the engine is out. A piston rod snapped hit both sides an cracked the sides and the oil pan.

Electronically controlled thermostat and sensor fail or get stuck at a much lower coolant temperature causing the dash to display the “steering assist is reduced drive with care.” It isn’t just a message, the steering is much harder to use potentially causing an accident. The ac completely doesn’t work causing potential for sensitive, elderly, or young children and pets to overheat inside, it’s significant risk of injury or death from the hot summer temperatures. The engine coolant temperature gauge is all the way down on C position which isn’t registering how hot/cold the engine gets potentially causing damage to the vehicle and a total loss of the vehicle entirely due to damage from the engine overheating. GM sent out letters to 2021 blazer owners which included a special coverage number N252508350 applying to people with this year having this problem and they have until 2036 or 150,009 mi to get the repairs made free of charge, they just bring the document with the special repair codes to the dealer and they fix it free of charge. After doing research online, this problem is affecting all years of the 2019+ blazers with the 3.6L V6 engine AND other known problems with other models and years of their other lineup of cars, it’s very widespread across their platforms. So what are people supposed to do when it isn’t the 2021 year? Pay an $800+ repair bill to GM when they KNOW it’s more widespread than just this year/make? This is a scam. I can’t even do the repair myself because I’m having trouble finding the correct parts online and not only that the repair is extensive, the whole top half of the engine needs to be taken apart just to get to the thermostat, we’re talking the airbox and intake manifold, all the plastic parts and shrouds and sensors covering engine, the fuel rail and injectors, pipes and clamps, engine coolant needs drained and refilled. It’s a major fix. I’m reporting this complaint to raise awareness and hopefully GM will do the right thing.

While driving my 2021 Chevrolet Silverado 1500 Trail Boss, multiple warning lights and messages suddenly appeared related to the ABS and brake system. The brake pedal became extremely difficult to press and the truck became unsafe to drive. The issue happened unexpectedly while the vehicle was in operation, creating a serious safety hazard and risk of accident or injury. After the incident, the truck was inspected by a mechanic who advised that the brake booster had essentially fallen apart and that I effectively had little to no braking capability. I was also informed that the condition and quality of the braking components were not acceptable for a vehicle of this age. This vehicle is only five years old and has been regularly maintained. For approximately the last three years, routine maintenance including oil changes, tire rotations, and inspections were performed at a Chevrolet dealership. At no time was I warned of any brake-related issue or safety concern. A major brake system failure should not occur suddenly on a properly maintained vehicle, especially without warning. This incident was extremely dangerous and could have resulted in a serious crash. I am submitting this complaint because I am concerned there may be a defect involving the brake system, brake booster, ABS system, or related components on this vehicle.
