Chevrolet Camaro shudder problems

Filed Aug 31, 2026 · Transmission · FL

I am writing to express my frustration and concern regarding the well documented transmission shudder issue affecting my 2018 Chevrolet Camaro LT. My vehicle currently has only 29,800 miles, yet it has begun experiencing the same symptoms described in Technical Service Bulletin (TSB) 18-NA-355. The vehicle's RPM gauge fluctuates noticeably, moving up and down while driving, and the car develops a significant shudder or vibration that can be felt throughout the vehicle. The issue is most noticeable during steady acceleration and cruising speeds. Not only does this affect the driving experience, but it also raises concerns about the long term reliability and safety of the vehicle. What is particularly troubling is that this problem has been widely reported by numerous Chevrolet owners and acknowledged by General Motors through TSB 18-NA-355. Despite the widespread nature of the defect, there has been no recall issued. As a customer, I find it difficult to understand why owners are expected to bear the financial burden of repairing a problem that appears to stem from a known manufacturing or design issue. A vehicle with fewer than 30,000 miles should not experience transmission problems of this magnitude. Many owners face costly repairs, including multiple transmission fluid exchanges, torque converter replacements, and in some cases transmission replacement. These expenses can be significant and create a negative ownership experience. General Motors has built its reputation on quality and customer loyalty, but issues like this damage consumer confidence. When customers encounter known defects and are left responsible for expensive repairs, it discourages future vehicle purchases and harms the brand's reputation. Many current owners, myself included, are reconsidering whether we would purchase another Chevrolet vehicle in the future. I respectfully request that General Motors review this issue and consider issuing a recall or extending warranty coverage for affect

Oh wow I don't even know where to start. The second I came home with the car for $32,995 off the used dealership it was a horrific disaster. I have replaced the rear fuse panel 2x already(water damage). The amp was fried from water damanage. The ambient lights and screen along with the gear lights only sometimes work. My morimoto aftermarket headlights wiring all have completely melted and needed to be replaced and that is just the small things. The car has always had severe driving malfunctions. These include: Jerking when putting into gear (any gear), shudders, it will rev up when i am braking, usuallu after a small hill or bump it will get really loud like it is in a much higher gear, it looses power and goes into random limp mode, the car has recently died in mid drive just completely lost acceleration power until it died. It will start right back up, but then same thing. Now when driving it will slightly jerk and steer to the side ever 3 seconds. Enough for me to hold the steering wheel tight. These are a few of the codes it reads, although some codes come and go, but these remain on: P12E7, P12EC, P12F4, P12F9, P0121, P0171, P0161, P0131, P069E, B097B, B1395, B1516, B1517, B260E, B260E, B2615, B2745, U0800, U1808, U0109, U007C. nOW MY BIGGEST PROBLEM IS THE CAR IS SO BAD IT IS NOT DRIVABLE AND NO ONE CAN TELL ME THE PROBLEM. IT VIOLENTLY JERKS WHEN TURNING AS IF SOMEONE HIT ME FROM BEHIND GOING 50MPH. iT USUALLY DOES IT WHEN I TURN THE WHEELS SLOWLY LIKE ON TURNS, BUT IT ALSO DOES IT WHEN STOPPING AT A RED LIGHT AND THE LIGHT TURNS GREEN IT JUST BOOOOOOM. iT IS SO LOUD AND AND SO VIOLENT IT IS AS IF MY BACK END FELL OFF. aLSO THE TIRES ARE LOCKED UP AND WHEN I TURN IT MAKES MY TIRE SCREAM. THESE PROBLEMS HAVE BEEN GOING ON SINCE I PURCHASED THE VEHICLE AND GOT IT HOME AROUND 70K MILES AND NOW I AM AT 160K WITH THE SAME PROBLEMS AND THEN SOME. The car twice now has driven itself when in park with car running. I put in park and was on phone at store and it drove

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.

The contact owns a 2016 Chevrolet Camaro. The contact stated that while driving at various speeds, the transmission unexpectedly shifted from first gear to third gear, the vehicle shuddered abnormally, and then jolted into the next gear. The failure also occurred while the transmission was downshifting. There was no warning light illuminated. The vehicle was taken to a local dealer, where it was diagnosed, and it was determined that the torque converter needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure and referred the contact to the federal safety agency Hotline to report the failure. The failure mileage was 32,670.

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.

Transmission Failures.The issue initially presented as intermittent trasmision shuddering, hesitation during accelaration, harsh and delayed shifting, and noticeable vibration, particularly at low speeds and during gear changes. These symptms progressively worsened over time and affected drivability and safty. Prior the failure, there were no warning lights or dashboard messages displayed. Based on professional diagnosis, they are consistent with internal transmission defects commonly reported for this model.(GM's-8 speed automatic transmition 8L45/8L90)Technical Service Bulletins TSB18-NA-335 and TSB16-NA-175.

I would like to report a safety concern with my car having a strong shuddering or vibration, including the steering wheel which I’m unable to move. When this happens RPM remain below 3000 rpm as if the the gears were having trouble changing, the shaking remains while driving in the city at around 25-35 mph and highway speeds at around 65-76 mph. My car was under warranty when this started happening, the dealership flushed and replaced the transmission fluid and it took care of the problem for about 2000 miles (GM has several bulletins in regards to the “shake” on different model vehicles since 2014). When the shuddering returned, I returned to the freedom Chevrolet where I bought the vehicle (actual mileage 53768) and explained the shuddering returning. I was advised to leave the car which now has been at the dealership for months and they refuse to fix the problem stating it is out of warranty. I provided all the bulletins I found on related issue which GM has stated they fix the problem by swapping the transmission on new cars but nothing has been done on the cars that have the existing problem because “there is no recall” as the service advisor stated. This problem could’ve been resolved when I took the car the first time but I wasn’t aware of the severity of the problem or that I would have so much trouble with the dealership now. All I asked is to honor the warranty as the issue was brought up when the vehicle was still under warranty and has less than 60,000 miles.

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.
