One week ago received a manufacturer OTA update to install in vehicle which I always download. A few days later I drove vehicle to store and turned vehicle off in parking lot for 5 minutes. Upon returning to vehicle, unable to start vehicle. Vehicle display provided message -??Battery Low Start Vehicle-?? but vehicle would not start. Tow company attempted to jump vehicle multiple times but not successful. Vehicle had to be towed for service. My vehicle is always stored in garage and plugged into battery charger when not in use and should not be dead. Vehicle Information System displays message -??Service Brake System-?? and -??Service Transmission Unable to Shift Soon-??. Vehicle unable to operate and awaiting scheduled service at dealership.

At under 3000 miles car started sputtering sporadically and stopped driving while in motion. We were able to get the car home. Tried to start the car back up and it violently surged. Car had no idea what gear it was in. Transmission service now light came on and car sent me an email stating to take it to the dealership. Had car towed to dealer and used tow company they requested me to use.. Dealer says valve body flooded and replaced it. Still not working correctly and dealer says transmission is being flooded. Gm engineers not sure why. Car has been at dealer over a month and have no clue when it can be fixed. When you shifted from park to reverse car would lunge violently like you threw the transmission into park while the car was moving down the street. Car is not safe to drive as it just started to have issues during regular use. Dealer has confirmed and recreated the problem. I was told if valve body didn-€™t fix it that gm would overnight a new transmission. Now I-€™m being told they want to continue to debug the issue and they have no clue on what the issue is or when it can be fixed. I-€™m out a vehicle I count on and am still paying for a car that I can-€™t have use of. Dealer is dodging my calls now. Here is my open case with Chevrolet asking about lemon law protections since it may be another month before I get my car back. [SR:9-7132169239 Car has under 3200 miles on it and is their flagship product.

At approximately 700 miles, my check engine light came on and the car produced an error message that said "Idle Creep Temporarily Disabled". Soon after that the car would lurch, buck on acceleration, and would only drive in even numbered gears. I felt the car was extremely dangerous and unpredictable to drive in this state since the car was unpredictably bucking and lurching forward and not shifting smoothly as usual. The dealer ran an OBDII poll and found five codes relating to transmission issues. GM has admitted to me that my vehicle is one of several that have "Assembly Debris" in the TREMEC supplied DCT. This "Assembly Debris" made the transmission filter completely black in appearance at 750 miles in addition to triggering the check engine light and dangerous driving behavior.
