NHTSA complaint #11744808 — an unverified report by a vehicle owner.
The transmission or torque converter has slippage and shuddering that has caused one or both to go bad. My safety was at risk due to this item beginning to fail to cause the inability to accelerate to maintain my position in traffic. The problem was recreated for the service technician. There was no warning or indication before this became an issue.
NHTSA complaint #11734708 — an unverified report by a vehicle owner.
The vehicle accelerated without input and the brakes failed to respond. I am notifying you that this vehicle is a life-threatening safety risk and should not be rented again until a master technician clears the electronic throttle control and breaking system. This condition presents a serious safety risk and could lead to a car crash or injury. Additionally, the vehicles, climate control system behaved erratically, alternating between extremely hot and extremely cold air without adjustment. This may indicate a broader electronic or system malfunction affecting vehicle city.

For about a week and a half my car had made a high pitched wheezing/hubbing sound when started cold. This occurred at all temperatures cold and warm. Yesterday December 13th I went to run some errands and about a mile into my drive my 2021 3lt 3.6 V6 Chevrolet Blazer lost the ability to power itself. There was no electrical problem however the power train lost power all gears drive and reverse. I was able to get off the roadway without incident. I scan my check engine light and had several check engine lights including a P 0796.

Increasing speed by itself, let foot off gas pedal and gas pedal sticking, 1st time I tapped brakes and it quit. 2nd time it did not. I had to slam brakes and hokd until the point they had overheated and smell burnt and filed a separate complaint for that today. Gas pedal sticking and self accelerating. Pedal to the floor accelerating. I do not drive like that and scared the hell out of me. I bout it 5 days ago from a Chevrolet dealership. I'm tired of rip offs. Next one best be brand new and they reimburse me for outside mechanical I inspection period. Bc I trust no dealer now. Went from 7p to about 95 in 10 seconds for 10 min. Not sure what braking did bx I coukd care less about the phone whike I am trying not to hit cars in front of me literally almost jammed an 18 wheeler and moving truck with me pushing the brakes as gmhard as I could.
NHTSA complaint #11687753 — an unverified report by a vehicle owner.
What component or system failed or malfunctioned, and is it available for inspection upon request? Multiple components in the engine timing and transmission system have failed. These include: Camshaft actuator solenoid valve failed twice (at ~30,000 and ~60,000 miles), each time with different DTC codes. Camshaft positioning sensor failed, triggering P0024 (“timing advanced and bouncing around”). Timing chain tensioner spring failed, requiring re-timing. Camshaft carrier case gasket experienced a major oil leak at 59,000 miles. Thermostat failed. Battery was replaced, but no diagnostic testing was performed—only code clearing. At 82,000 miles: Torque converter has failed, transmission fluid is tarnished, and the radiator is leaking internally. Yes, the vehicle is available for inspection upon request and has been registered as non-operational. How was your safety or the safety of others put at risk? The vehicle exhibited repeated hesitation, delays when accelerating, and revving while braking. In stop-and-go traffic, it now sputters as if it may stall. These behaviors create unsafe driving conditions, especially at intersections and in congested areas, putting both myself and other drivers at risk. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The torque converter failure and transmission issues were confirmed by National Transmission in Long Beach, CA. Prior component failures were confirmed by Martin Chevrolet, who performed both camshaft actuator solenoid valve replacements under warranty. Multiple DTC codes were recorded and cleared, but no electrical testing was performed. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has been serviced by authorized GM dealerships, but GM did not escalate the issue to their TAC (Technical Assistance Center) or assign a field engineer, in violation of GM's internal escalation policy. No inspections
NHTSA complaint #11659014 — an unverified report by a vehicle owner.
engine - code p0128 engine coolant thermostat. This is a safety issue because it reduces the power steering on vehicle, auto stop stopped working, unable to remote start vehicle. Issue has been confirmed at an independent service center (I work at an auto collision center). Warning lamp - check engine light. Message on dash - power steering reduced. Appears everything came on at the same time. Per dealership items most likely needing replacement are engine coolant thermostat and engine coolant temperature sensor but ecm module could also need replacement. Advised common problem but no recall power train - transmission shutters when accelerating. Safety is at risk because vehicle will not accelerate or accelerate too quickly. Called to dealership advise flush transmission fluid twice to fix issue. We have done this 4 times in the past year. Shutter temporarily reduces but does not go away. Per service advisor it is a "function design" and if flushing transmission fluid does not fix issue then transmission will need to be replaced. There are no warning lights or messages on dash electrical - vehicle says shift to park when vehicle is in park and will not allow vehicle to turn off. It is a safety issue because vehicle will not shut off. Problem confirmed by an independent service center we have already replaced the in-line wire harness jumper. This did not fix the issue. Advised from service center that entire shifter would need to be replaced.
NHTSA complaint #11656851 — an unverified report by a vehicle owner.
I bought a 2019 Chevy Blazer in February 2023 . The vehicle has issues when I fill it with gas. As soon as I gas up to full it starts jerking immediately afterwards. It makes loud popping sounds. The engine dies completely. It starts to tremble and will not go. When I try to turn in back on , the starter works very hard before it will turn back on. It does turn back on eventually but I have to pull over to the side and accelerate the engine until it finally stays on. I drives that way turning off at lights and stops. After about 10-15 minutes of this , it finally stays on long enough to drive another 20 minutes or so to get home. After it rests for a few hours, it goes like normal. This is a big safety concern for me since these episodes happen every week when I fill up my car with gas. I have almost been hit from behind during these episodes and it is very scary and such a hassle to have to deal with this every week. I have already had several Chevy dealers and mechanics work on this problem and it continues to act up like this. I have all the paperwork for the work that has been done. $15, 000 have already been spent on this problem and the problem still continues. Please help me. I like chevy vehicles and have always bought chevy but this is the second chevy vehicle that has given me problems when I gas up. Please look into this problem. My phone number [XXX] if you need to make contact with me by phone. Thank you [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
NHTSA complaint #11653151 — an unverified report by a vehicle owner.
I was driving down the highway at 70mph using the adaptive cruise control. There was nobody in front of me, and suddenly the vehicle started picking up speed. I looked at the cruise control and it said 115mph, so I hit the brakes to override it and slow down. when I reset it for , ~70mph again it worked fine. This happened to me two other times with the same basic scenario. The speed is always over 100mph, and it always occurs when the adaptive cruise control has been in use for at least 30 minutes. I have an appt with the dealer that I bought it from to have it looked at. No warning lights and no other symptoms.
NHTSA complaint #11630250 — an unverified report by a vehicle owner.
The contact owns a 2023 Chevrolet Blazer. The contact stated that while driving approximately 50 MPH, the vehicle experienced unintended acceleration and the speed increased to over 70 MPH. The contact indicated that while depressing the brake pedal the vehicle failed to slow as needed and the parking brake was activated to eventually stop the vehicle. The vehicle was later towed to the local dealer who was unable to determine or confirm the unintended acceleration failure. The contact was informed that the brake rotors and brake pads needed to be replaced due to excessive wear. The contact stated that during a previous unintended acceleration failure, the speed was reduced while depressing the brake pedal; however, the vehicle would accelerate when the brake pedal was released. The manufacturer was notified of the failure, but no assistance was offered. The approximate failure mileage was 9,000.

When slowing down (at the end of a street for example) foot is on the brake but the car will jerk and engine revs as if it is trying to still accelerate forward without moving the gas pedal. The rpms increase. No warning lights, vehicle has been inspected. No issue found by dealership.
NHTSA complaint #11453869 — an unverified report by a vehicle owner.
The service advisor at the Chevrolet dealership denied a repair to my abs control module because it was a “known issue”. He told my wife and I our car is unsafe to drive And still wants to give it back to us. Other Gm vehicles have recalls open for the same issue one needs to be open for this. Abs lights and multiple others no brakes or random braking.
