Accelerator Pedal Sensor problems of the 2016 Chevrolet Traverse

Stabilitrack message comes on and reduced power for no reason. Loses power instantly and have to pull over. Turns back on and check engine light still on, but can drive as normal until I turn it off and who knows when it comes back. Several times has acted like it is stuck in 4th gear while in drive. Reverse is okay. Other times it has not started, at all. I brought it in and dealership said it was battery. Replaced it, then worked ok for couple days, then same problems started showing back up. Brought back in and code p2138 showed up indicating pedal position sensor. I replaced pedal and the issue of reduced engine power has not come back yet (3 weeks). Other issues have recently shown back up (not starting sometimes, stuck in 4th gear). I have had the car for just over a year (bought it from enterprise with 14,500 on it), and now have 71,000 miles and having way too many problems for it being all highway and driving it easy. Too many other people with same problems not to have it fixed/recalled by chevy. I used to be a chevy guy, now may move elsewhere. . . . .
