The engine light has come on 3 times with a truck with only 9000 miles on it I took it to the dealership who gave me a code of p12a6 they told me Chevrolet is aware of this problem but has not come up with solution yet or even wrote a program to reflash the computer. Now I have a paper weight in my driveway and being that I live in a dual town trying to find a dealership that will fix it and provide rental car or truck. This defect can be multiple reasons with the engine harness wires chaffing or torque converter or transmission plus the whole electrical system not cranking over the truck from what I was told last time. Now I'm waiting till 730 to call a dealership see if they have a roll truck to pick it up and get it to a dealership where they can try to fix this problem.

2020 silverado rst 1500 4x4 allstar with 8 speed transmission. At 4,000 miles developed a shutter in transmission and slipping and hard shifting mainly between gear 1-2. Bad enough when you start from a stop when it shifts you fall forward. The acceleration pushes you back and then it just slips to no where till it catches and goes. Contacted shop and was told at 1st oil changed they would flush the fluid per the service bulletin. This made it way worse. Shifting is more rough and shudder is more frequent. Took it back for the 2nd time and had to drive with a tech so they could experience the issue. It is going back to the shop tomorrow 1/11/2020 with only 7,500 miles with hopes of a new torque converter. This should be a recall and result in a class action. This issue is so common and this truck is brand new. Had it in shop with 2,000 miles with an oil leak.
