No crash or injuries. My Jeep only has 45,000 original miles and it is leaking oil from the oil cooler. I researched and this seems to be a very common issue with the 2015 3. 6 l Jeep Wrangler. It cost over $1,500 to repair. As the other gentleman stated in his complaint, I feel this is a major issue that needs to be addressed by Jeep. See the other post below for further detail: I own two Jeep Wranglers, a 2013 and a 2015. I had the 2015 repaired at a cost of over $1,000. 00. Now my 2013 has developed the same problem; to wit, the oil cooler/ oil filter housing cracks on Chrysler 3. 6 engines and the oil is spread onto the exhaust pipe which has the potential of causing a fire. If this is not discovered, the oil will spread to the rear tires which will cause a traction or braking hazard. Chrysler has not modified the housing and when you replace , it is replaced with the same part that will fail in the future. Chrysler has to know that this problem exists by the # of units that they have sold, not to mention the thousands of units that are sold on ebay and automotive parts stores. There should be a recall on this situation before people are injured or killed.
