One problem related to differential unit has been reported for the 2016 Jeep Wrangler. The most recently reported issues are listed below.
I have gone through over 4 sets of mud terrain tires over the last two years that are unevenly worn and no one knew why. Most recently, the rear right tire had a sidewall gash and had a flat tire, we began smelling smoke and ended up taking the Jeep into brakemasters and was told the entire rear differential was failing and falling apart. We had the rear diff replaced, brakes, rotors and paid $5000 out of pocket and as I was driving from home to tucson the other day to my maternity appointment, the back right tire began screeching while not braking and began sizzling and burning with oil coming out from the tire. I immediately stopped at the nearest brakemasters and they said that an entirely new rear differential is needed. Not only could the Jeep have caught on fire with this safety issue but I kept losing control of the steering in the middle of the city with a 2 year old and one on the way. I am hoping to see some sort of resolution on this and to be communicated with other Jeep owners of this safety issue.
