Headlight Switch problems of the 2013 Jeep Grand Cherokee

I have a 2013 Jeep Grand Cherokee, I have taken my car to the dealership twice now for the engine stalling as I climb a hill and for it kicking into gear when sitting still with my foot still on the brake. The car jerks extremely hard to the point where you think you have been hit by another car. It also does this when switching between the first 3 gears. The first time I took it in, the dealership told me they had to adjust the computer on the engine. This did not work as I am still experiencing the same issue. I also have noticed a decrease in my mileage per gallon. I was getting 14 and am now getting 9 miles per gallon. My outlet buttons are all sticking on my dashboard and are hard to the touch to turn on. When trying to turn on one button, all buttons light up. Ie. . Parking assistance, skid control, etc. My headlights also would not turn on when driving. The only lights that worked were the high beams. This has happened to me three times while driving. The dealership states that they can not replicate the issue.
