NHTSA Complaint #11698910 — 2015 JEEP CHEROKEE

My Jeep has been returned to the Dealership I purchased it from now for the 3rd time to have the Rear Differential completely replaced. The first time, because the Rear Differential axle seal was leaking. The 2nd time, the rear differential had another axle seal leak. This is now my 3rd time where I have dropped off my Jeep because of a noise coming out of the Read Differential, and the Dealer states it needs to be replaced, with under 1 year from the previous replacement. My Jeep has been sitting in the Dealership since Oct. 17 and the dealer is saying that Stallantis has over 400 of these rear differentials on back order. On Friday November 14, will be 5 weeks and now I cannot get my Jeep back, because the Dealership is saying the manufacturer has no estimate for when a new Rear Differential will be available. This has been a major defect since I purchased the vehicle as well as other Jeep owners saying the same thing. Now my dealership cannot release my Jeep, due to the mechanical breakdown, and I may never get my Jeep back due to Stallantis not manufacturer the parts fast enough for dealers to make the necessary repairs. I need someone's help!
