2019 Chevrolet Camaro: shudder or vibration when accelerating

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.

Was stoped at a stop sign. When I tried to accelerate the car acted like it didn’t want to go and the back wheels locked up causing a screeching noise. Before coming to the stop sign it felt like it was having a shuddering affect. Luckily there was no traffic and it finally shifted out but wouldn’t accelerate very well. I was able to make it home and the Check engine is now on. It was definitely scary experience and now I’m kinda afraid to drive it. This car is low mileage (less than 50k) and a daily driver.

I am reporting an issue with my 2019 Chevrolet Camaro 2LT RS involving a faulty torque converter. The vehicle began showing symptoms consistent with transmission shuddering and performance issues. After diagnostic evaluation at a certified Chevrolet dealership, I was informed the torque converter needs to be replaced and the transmission fluid flushed. Upon researching, I found that this problem is covered under a Technical Service Bulletin (TSB) issued by GM for this specific model and year, indicating it's a known issue. However, my vehicle is now out of warranty, and GM has not issued a recall despite the safety and drivability concerns. I believe this defect should be investigated further, as it poses a risk to vehicle performance and potentially driver safety.

2019 Chevy Camaro transmission is shuddering. In other words it feels like my car is running over rubber strips on the road between 40 mph to 80mph. I know there is several TSBs that GM has put out on this issue with the A8. Went to Lynn Smith Chevrolet on 07/06/2023 and was told since my car is out of warranty it would cost me 625 dollars to have the transmission flushed and have the new synthetic transmission fluid in it. They said that’s the first step GM wants service depts to do. I’m sorry but if GM knows this is a problem then there should be a recall on it. I know there are already class action lawsuits on this problem. I can’t afford to have my transmission drained 2 or three 3 times. It is causing safety risk when you accelerate and lose power on the interstate or it is sluddering as you pick up speed at a red light.Thought the problem was my tires so had 2 new sets put on and realized it wasn’t the tires.
