I have a 2015 fwd Renegade, and have had ongoing transmission problems. I finally found a dealership that was willing to help me look into the problems. I dropped it off to them, so they could let the car sit for a bit, and they were able to feel the jerking after going from reverse to drive, like the jeep couldn't shift fully into 1st gear for a moment. They did several updates and gave me the car back. It was actually a lot worse once I got it back, would jerk in the first 4 gears, instead of just one, and my gas mileage went from 26-32 mpg down to 17-19 mpg! Took it back in and they said they had to "re-train the transmission manually. I just picked it back up yesterday evening and on my drive to work today, I noticed my RPMs jumping between 2 1/2 to 1 1/2 and then back to 2 1/4, all while the jeep was in cruise control with no speed change, or hills, like it couldn't make up its mind what gear it wanted to be in. I can also really feel when it shifts and downshifts, something that never happened before the updates. I did get my gas mileage back thankfully. So I guess my question is, is this normal after the updates? Should I take it back again? My full warranty will be up in about 1,400 miles and I just want a normal shifting jeep!!
