The contact owns a 2015 Chevrolet Corvette. The contact stated that the vehicle experienced severe shuddering and vibration while accelerating from a stationary position and while driving at slower speeds. The cause of the failure was not yet determined. The manufacturer and local dealer were notified of the failure, but no assistance was offered. The contact was provided information of a TSB related to the failure. No further information was available. The failure mileage was 13,000.
Torque converter shudder and noise (definitely and issue related transmission). Around 1,500 rpm the vehicle starts to experience the shudder, shaking, and noise. Additionally there is a feeling of a surge in power, like if the vehicle shifts to an upper gear un intentionally, the vehicle launches forward occasionally (lurching forward). There is absolutely no issue while the vehicle idles, not at low or high rpm. The issue only occurs while the vehicle is in motion and at around 1,500 rpm. Using a v4 to v8 delete (range technology ra003b afm/dfm disabler) helps the issue significantly but it's still an issue. If that disabler is removed the issue is extremely pronounced. I purchased this vehicle as a used vehicle. I wouldn't have purchased the vehicle if I had the slightest idea of such a major issue with the vehicle.
The transmission flutters when shifting on my 2015 Corvette. A potential catastrophic failure could cause a fire from transmission fluid hitting the hot exhaust. General motors is aware of the issue and has issued a TSB. I believe a potential fire and or collision exists if transmission fluid spills on the pavement. Transmission fluid could cause spinouts of vehicles on road behind a car with failure. My vehicle has been experiencing this for the last couple months. Two different dealerships offer to change the fluid in the transmission but no guarantee the internal components have sustained damage.
Transmission shifts hard between first and second, intermittent shudder every 2 to 3 seconds when driving down road at normal highway speeds coming from transmission.
TSB 18-na-355 - vehicle is experiencing a shake and/or shudder during light throttle acceleration between 25 and 80 mph (40 and 128 km/h) steady state driving when transmission is not actively shifting gears. The experience is similar to driving over rumble strips or a concrete road surface with rough expansion joints. Took to dealership to repair, but they are stating the warranty ended in January and requiring me to pay for the fix. Will join the class action lawsuit.
The vehicle is equipped with an 8l90 automatic transmission. It has a severe shudder problem when cruising down the road at 50 to 70 mph. Can get almost undrivable. Also will not upshift after a performance downshift. Dealer flushed transmission per gm bulletin but problem is still there. Looks like almost all of gm 8 speed transmissions have this problem circa 2015-2016.
I've almost been hit twice pulling into traffic on a city street with this car. Shifting when the transmission is cold into 2nd gear from 1st gear is near impossible and appears to be a known problem based on my internet search. Several times I've pulled into traffic and couldn't shift it into 2nd gear. By then the car is slowing down with traffic bearing down on it and you have to slow down even more to go back to 1st gear. The local dealership says this is normal but I disagree because it's a safety issue. I have to rev the engine higher and go directly into third gear to protect my life.
Torque tube or drivetrain (known issue by gm) causing danger to driver & passenger life while driving on road at any speed. Car purchased from official gm dealer in dubai, united arab emirates = al ghandi auto. Both gm & dealer in dubai refuse to acknowledge the several service bulletins (tsbs) for my affected vehicle, and are expecting me to pay a large amount of money for replacing a part which is already known by gm to be manufactured as defective and cause engine and transmission damage (and cause for probable accident and/or death) irrespective of mileage or warranty status. Car has been serviced only by gm dealer at 10 routine service intervals, and this issue or relaed TSB was never reported to me (the customer). Car is driven less than 60,000 miles and has zero accidents. Gm is endangering my life and the lives of all Chevrolet Corvette owners driving high performance cars with major known issues. I am fearful for my life and the safety of my family. Both gm and the local gm dealer refuses to acknowledge or discuss this serious and deadly issue. Is there any level of accountability from american auto makers, and can NHTSA please help my voice, concern, and complaint reach the right people at gm USA, gm uae, or al ghandi uae? afraid to drive & die, rahul sainani rsainani@gmail.

Slow down shift. When you hit the accelerator while the car is down shifting, there is a 2 second delay. I came off express way and turned on to road then hit the gas to merge into a lane when there was a 2 second delay. Very dangerous. How do I fix problem? why is Chevrolet not fixing problem.
8-speed automatic transmission always shifts erratically when starting out cold (lazy shift, slow shift, etc. ) and occasionally does not downshift when car comes to a stop, only to slam hard into 1st when gas pedal is pressed to resume travel. Dealer says gm claims this is "normal," but no car I've ever owned behaves like this. Appears to be fluid starvation internally. Any fix/replacement would be costly for gm, so given their history w/faulty ignition switches, not surprised they're trying to avoid it. Transmission is definitely not normal and behavior is unpredictable + unacceptable -- especially at this price. When car is moving & transmission is in drive and trying to lazily shift gears, you temporarily lose ability to apply power, which is both dangerous and unnerving. Clearly, this transmission was put into production w/inadequate testing & development. A recall is necessary to fix properly.
The a8 automatic transmission in the 2015 Corvette is prone to occasional hard downshifts from 2nd to 1st gear when driving at slow speeds (less than 10 mph). Sometimes the downshifts are so violent that the car jerks forward several feet. The first time it happened I thought I had been rear ended by another car. The unpredictable behavior of the transmission is especially dangerous in proximity to pedestrians or other vehicles.
