One problem related to engine burning oil has been reported for the 2012 Jeep Wrangler. The most recently reported issues are listed below.
The oil filter housing has a manufacture flaw, which causes engine oil to leak in the engine bay and onto the exhaust. Thousands of customers have had this same issue in their Jeep Wranglers. It does not matter the age or mileage of the vehicle. The malfunction has accrued in Jeep Wranglers with as little as 2k miles on them. The malfunction is not only a health but safety risk to drivers and their passengers. When driving the cabin fills up with smoke from burning oil and has a high potential to ignite and cause a fire. When Jeep repairs this issue they use a new part number, and not the stock application. I want to point out that I'm finding this is the case with a number of Chrysler fiats brands with the penastar 3. 6l motor. I my have this issue now, and have had it on both of my 2012 and 2013 Jeep Wranglers. Again, there are thousands of reparota online with Jeep owners with the 3. 6l penastar motor. 2012-2014. The issue was fixed by Jeep engineers in mid 2015.
