NHTSA Complaint #11619952 — 2020 JEEP WRANGLER

My vehicle had been experiencing loud acceleration as well as difficulty while driving. Upon taking the vehicle to the dealership where purchased they informed me the rear differential on the vehicle was starting to fail. They informed me they had ordered the part from Mopar with no recollection of when it would be in other than it stating it was on backorder. We have tried getting in touch with Mopar over expediting the piece to be told they also have no idea when it will be in, but they are working on it. The vehicle has been messed up for over a month and is worsening. I am having greater difficulty driving it and at points it begins to bounce while moving. It is getting to the point I am now starting to worry for my own as well as others safety because I am unsure when it will fully stop working.
