Hello, first post here unfortunately but I have been a long time lurker.
2014 LTZ RS with 1.4L automatic and 34,000 on the dot. Located in the U.S.
I went to pass a car doing about 30-35 and gave half throttle. The car downshifted to ~3,000 RPMs and I began accelerating. Suddenly the car began bucking horribly and the check engine light and the TCS light come on. The DIC showed "Service Stabilitrak" and "Service Traction Control" messages. I pulled into an Advanced Auto to have the code read, but they no longer read CEL codes. Get back in the car and drive, without issue or any CELs to Autozone right down the road. They can't read the code unless the CEL is on, but it turned off and the car was running fine. Go to head home, the car is driving fine until I have to accelerate from a stop light up a hill. The same CELs and DIC messages from before but this time without the TCS light. Limped it home and parked it but anytime under load it feels like the TCS kicks in and the engine cuts power. Similar to trying to floor it up a hill in slush. It's going to the dealer Monday but I wanted to know if anyone had experience with this.
