On January 17,2020. I was drive with my son going about 35miles when all of a sudden my stalled out or felt like it did but continue to drive. The check engine light turned on and the dashboard screen stated engine power was reduced and my stability needed to be serviced. Or something like that because it wasn't on to long. Luckily wasn't going to fast and there were no cars behind me. I've researched other complaints and I'm not the only one. This needs to be addressed because if that would to happen on a busy highway.

When driving the car will not respond correctly to the accelerator, delayed response. The car will also not shift correctly (as thought you are shifting manually). While driving the vehicle's gauges will jump up and down followed by the check engine lights coming on. Car will then go into reduced power mode. When pressing on the accelerator the engine will rev and then the car slams down into 2nd gear. The car has been in a GMC certified garage 7 times and out of service while in the garage 40 days and counting. Numerous attempts at repair have obviously been unsuccessful. Gm is refusing to by the car back because I bought it at premier Chevrolet GMC in morgantown, wv used with 27,768 miles on 2/5/17.
