I have a 2015 corvette stingray with 35k miles. The vehicle has been to the dealership 2 times already once at 11k miles and second time at 22k miles where the car should shudder while cruising at low speeds. Also in the morning during a cold start when I would shift the car from park into reverse then the car would do a hard shift. Twice the dealership changed the fluid in the transmission and rebuilt the entire transmission since the car was under warranty. But my car's extended warranty expired on 03/01/20, in 06/01/20 the issue came back. Now gm is refusing to take responsibility to fix the vehicle. When refueling, tank filler pipe accepts fuel only very slowly. Several different gas station pumps were tried, all kept clicking off every 3 seconds (as if tank was full). Tank was empty to take in several more gallons of fuel.

Veh purchased 9/2015 and so far I have replace four rear rims and one front. All have hair line cracks on the inside of rim causing radical air loss, vibration and tire wear. Navigation screen flickers and goes on and off at least two times a week and I have to open and close to restart screen. Blower motor went out at 37k miles and the transmission is bucking, vibrating, shuddering and going into 5th gear at 31mph and feels like it is hanging up in 5th gear the clunks down to first at 10mph. Went to dealer, they claimed they did a software up date and things are fine. Left the dealership and came back 5 min later with same issue. Took service manager for a ride and he confirmed the horrible ride. Have to take back on tuesday 5/28 and it feels like the drive shaft or rear end will fall out. They said it was fine. I hope nothing happens to me or the car.

8-speed automatic transmission 'bucks' and 'clunks' during acceleration or during up shifting. It does this either in full automatic or manual shifting mode.

2015 corvette stingray z51 - 8 speed automatic transmission torque converter. With only 7,500 miles on the car it started to run jerky and rpms would fluctuate for no reason (especially at highway speeds when fully warmed up). Often felt like driving on a washboard dirt road. After a cold start, there was a delay after shifting into drive. When it engaged after several seconds it would do so violently, lurching the car forward suddenly. Dealer diagnosed faulty torque converter as defective and a known problem with these transmissions. After less than 2,000 miles the symptoms returned and the dealer again replaced the torque converter. So now I'm on my 3rd defective tc. After 1,700 miles, symptoms returned again! Dealer said that chevrolet and gm have ordered a stop on replacing the tc's since no fix was available. Gm advised to drain and flush tranny, refilling with mobil1 transmission fluid. This seemed to work (only for a little longer) but is worrisome because in the future service, a technician will likely refill with gm fluid, not mobil1. Especially if a second owner. Now at 16,100 miles the symptoms are returning! Jerkiness, slamming into gear after a delay on cold starts. Gm seems to have turned their back on stingray owners by kicking the can down the road beyond warrantee (with the mobil1 "band-aid fix"). On the forums there are so many owner complaining about this same issue. I am amazed that there is no official investigation resulting in a recall. This z51 lt3 stingray was $75,000 otd! For this cost we should be able to expect a quality vehicle and a motor company that stands behind it! Can somebody please help us with this serious and potentially dangerious problem?

Automatic 8 speed transmission had to be replaced at 2000 miles on the odometer due to hard shifts and shifting automatically to low gear at highway speeds nearly bringing the car to a stop in interstate traffic, now 700 miles and 4 months later the transmission is stuck in second gear and you cant drive fast enough to get out of the way of traffic. And I know of several other cars like it that have similar problems. This is a real safety problem and gm seems to ignore it, probably until someone gets hurt or killed.

8 speed automatic transmission down shifts at a stop with such force it feels as you have been hit from behind by another car while coming to a stop. Transmission also will not always engage properly and will over rev and slam into gear possibly causing an accident. Transmission at times will disengage while going forward then slam into gear with great force. I was told by a gm insider that gm is aware some transmissions are defective and is working on a kit to fix the fluid starvation problem internally but has done nothing to inform owners of the potential dangers of erratic shifting that it's causing while driving. This also causes the transmission to over heat and to illuminate a warning lamp.

I was driving on the freeway at night on my way home around 11pm when my low beam lights went dark and would not turn back on.I've checked all the forums about this problem and it is happening a lot, but apparently gm wont include the 2008 vehicles even though ones like mine have the same equipment as earlier models with the same problems. A few days prior, my girlfriend was driving the car, and complained about the same problem, but I just thought it was because she didn't know how to operate the car. Once I get it fixed, how do I know the lights wont mysteriously go off again?! I'm very disappointed in all the electrical problems with this vehicle, and this is the last straw. (after only 38k miles the fuel tank gauge stopped working. At 60k miles the car was having issues with overheating because the fans wouldn't turn on. At 75k miles a clunking noise started coming from the differential. It's a stock car mind you. And now at 85k miles 2008, the headlights wont turn on. Gm simply won't stand behind the car, and so I've been left to figure it out on my own. So much for buying my dream car. It seems more like a nightmare.)
