Been loving my 2019 SCREW. It has been the perfect truck for me until today. I am have an issue that hopefully you guys can help me with. I was driving home and the truck was running fine until suddenly it felt like I was going oved speedbumps or more like a washboard dirt road. Other indications are the engine light is flashing, the AC stopped working (including cooled seats) and white smoke is coming out of the exhaust. The bumpy feeling is still there even when stopped. The throttle response is pretty much gone. It seems to do better when I put it in manual and use the paddle shifters but I still feel the bumps when stopped on idle. I just drove it home and won't drive it again until I take it to service. Or should I get it towed? It's still uder warranty. Any help is appreciated.
