Three problems related to transfer case have been reported for the 2014 Jeep Wrangler. The most recently reported issues are listed below.
The oil cooler broke and is leaking oil all over my engine, transfer case and exhaust. Jeep says it's common and they expect me to pay $850 out of my pocket for a plastic part that will fail again. Shame on them. It was sitting in my garage and oil is everywhere on the ground. It's too dangerous to drive.
The mechanism of what happened to my vehicle is undetermined whether it was stationary or while driving. However I noticed a massive oil leak after driving. The entire under side of the Jeep where the transmission and transfer case are were completely soaked in motor oil. After taking it to a Jeep dealership, they diagnosed it to be a leak coming from the actual oil cooler housing. Come to find out my vehicle has already passed its warranty coverage date. And after doing a little bit of research, it seems I'm not the only person who has had this problem with their Jeep, not specifically just the 2014 models others as well. Other than the complaints from individuals who have purchased a Jeep, I have yet to find any comment from mopar, Chrysler, or the Jeep manufacturer themselves addressing the issue of having a plastic oil cooler housing. Fyi its not that easy of a repair so it could be quite costly to some.
Transfer case rear main seal leak as diagnosed by two different Jeep dealerships (Jeep of hollywood and massey yardley Jeep). I have taken the car in twice for repair and the leak continues (02/24/2017 [hollywood Jeep] and 03/08/2017 [massey yardley]). The car is in for reevaluation and repair as I am writing this making it the third time in three weeks the car is being repaired for the same issue (03/17/2017 [massey yardley]). This involves the motor oil in the vehicle and leaks regardless of whether the vehicle is idle or being driven. Once the Wrangler is driven the the oil heats up, and thins out, causing the oil to leak in larger amounts and faster. This is a safety issue because leaking oil can start an engine fire or too much oil lost can cause an engine to be damaged or even seize. Jeep corporate customer service has been notified of this issue and their "case management" team has been involved in attempting to resolve the issue, however, to-date all customer service reps indicate there is no recall or investigation into these issues. As an aside, the car was taken to the dealer, by the original owner (per carfax report), for transfer case related issues 11/18/2015. I implore NHTSA to investigate this issue as this has the potential to be a life threatening issue.
