NHTSA Complaint #11428440 — 2015 JEEP CHEROKEE

When I go to put the the vehicle in park and reverse it wants to shift really hard, not really a shift but more of a jerk. It doesn’t happen every time but it does 50 percent of the time. There was this one time where i went to go put it in reverse and it wanted to rev more then usual. When it MAINLY shifts hard is when I first turn it on and start moving a couple feet it wants to fall on its face. We haven’t had any incidents in it yet but I wanted to see if I could get anything done before any. Me and my boyfriend travel a lot and when we are in traffic it has fallen on its face. There is a gas cap light that keeps coming on and I have replaced my gas cap 2 times.
