Chevrolet Camaro sudden acceleration problems

Filed Apr 26, 2026 · Transmission · FL

The vehicle is experiencing a severe and dangerous transmission defect that manifests as intense shuddering and vibrations followed by instances of random, unintended acceleration. Specifically, while operating the vehicle at various speeds, the transmission fails to engage properly, causing a violent vibration/shudder. This is frequently followed by the vehicle surging or accelerating unexpectedly without increased pressure on the gas pedal. This condition creates a significant safety hazard as it compromises the driver's ability to maintain a constant speed and control the vehicle in traffic or during low-speed maneuvers. The random acceleration is unpredictable and poses an immediate risk of rear-end collisions or loss of vehicle control. General Motors (GM) has issued multiple Technical Service Bulletins (TSBs) regarding this specific 8-speed transmission defect (shudder/vibration), yet they have failed to issue a safety recall. My vehicle began exhibiting these life-safety symptoms approximately two weeks after the 100,000-mile powertrain warranty expired in August 2025. A licensed transmission specialist has diagnosed the issue as a torque converter failure and transmission fluid contamination, consistent with the known defects identified in GM's own TSBs. Chevrolet has refused to remedy this safety defect at their expense, citing warranty expiration, despite their documented prior knowledge of the systemic nature of this failure. I am reporting this to the federal safety agency because the random acceleration component of this defect is a clear and present danger to myself and other motorists on the road.

Vehicle is doing a hard shift from first to second, severe shuddering, sometimes when braking vehicle acts like it wants to surge forward took to a transmission shop I have a bad torque converter and was told this is a problem with the 8 speed transmission from GM. This is a known issue with these transmissions that GM /dealership knew and refuse to fix. The vehicle stalled on me on a road at night where there's no stores, I'm a female alone on a dark road for about 30 minutes trying to get car to start. Luckily it did. This could've caused an accident and my safety was at risk being stranded alone at night. I was told to not drive the car until fixed. I do not have the funds to fix this issue and GM does not respond to requests, Chevrolet is not helping either.

The contact owns a 2020 Chevrolet Camaro. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated, prompting the contact to pull over to the shoulder of the roadway and shift into park. Upon shifting back into drive, the vehicle suddenly accelerated independently. The contact was able to regain control of the vehicle before a crash could occur. The vehicle was taken to an independent mechanic, who was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the vehicle was inspected. The failure mileage was unknown.

I’ve been experiencing my acceleration and brake pedal engaging without my intervention. While driving , a sudden unintended acceleration will occur followed by the brakes engaging by itself. With the sudden acceleration, fail to accelerate, & delay stopping, all of these factors can cause danger to both the passengers in the car, including myself & others on the road around me which is a very big safety issue. In addition , with the problems i was experiencing & engine light being on my display i took the vehicle to be inspected by Don Mealey Chevrolet in Clermont, Florida 347811 on March 31st 2023 . The DTCs Read showed Active, failure code0x00: P0700 Transmission Control System(MIL Request).

I would consider this as an incident.

Water shorted the app circuits and caused the throttle to activate with out driver input. Water is a potential cause for sudden unintended acceleration in vehicles equipped with potentiometer type app sensor's through extensive research between august 2019 and september 2020, I have determined that a water intrusion problem into the instrument panel (ip) to body harness connector, which carries the app sensor signals to the ECM/PCM has the potential to cause sudden unintended acceleration in many of the 2005-2018 gm product line. Water can enter the connector through body leaks and may cause an increase in voltage on app 1 and app 2. On some vehicles this can also cause a malfunction in the bpp/brake switch status circuit. As a result this malfunction can mistakenly appear as a pedal misapplication in the edr report from the sdm. This finding applies to many other vehicle using a potentiometer type app sensor but the research was done specifically on gm vehicles. I have also determined water intrusion into the connector 109 on the full size truck line has the possibility to cause false activation of the app circuit. Using water I have confirmed that water can cause the voltage increase on app circuit 1 and app circuit 2 and not enter reduced power mode, it all comes down to surface area exposed and sodium content in the water as to the final results. As these vehicles become older the likely hood of these events occurring increases. Vehicles near salt water or where salt is used on the roads are more likely to fail with higher app %. Because of the known water leak into the connector's containing app wires and verification that water can cause false activation of the app circuits. It is my conclusion in rare events this water could cause false activation of both app signal in many of the 2005-2018 gm vehicles. This vehicle was used for confirmation.

10/26/2012 - pulling into parking space at low speed. Car suddenly accelerated. I assumed that somehow it was my fault. Impacted a second vehicle. 02/23/2015 - exact same thing. Pulling into parking space at low speed. Car suddenly accelerated. I was able to slam on the brakes and prevent a collision. I googled "camaro unintended acceleration" and found a video clip of another person appearing to have the same problem.
