NHTSA Complaint #11626993 — 2016 CADILLAC ATS

I’ve only had this vehicle for about 2 years now. I purchased it off of Carvana and had 30 days I could’ve returned the vehicle if there was issues. When I first got it, I noticed the vehicles gas pedal would shutter a tad while going up a hill or at a higher speed like on the highway. It would also jolt a little while taking off but when I took it to the dealership they were saying everything is normal and I believed everything was fine since there was no lights on the dash, it was my first time ever buying a car myself, and I had no reason not to trust them. The vehicle is now at a little less than 85,000 miles and I can’t drive it because of how bad it’s jerking, I did a little more research and come to find out this is a huge issue with GMs vehicles transmissions within that years range however my vehicle in particular isn’t on that list. The CTS and i believe even a few ATS Vs were on there but mine is doing the same exact behaviors as they’re describing. If there’s any way you guys can help me out it would honestly be a blessing
