One problem related to manifold/header/muffler/tail pipe has been reported for the 2018 Jeep Compass. The most recently reported issues are listed below.
We bought the Jeep new with 8600 miles on it. 4000 miles after our first oil change at the dealer, the engine oil light came on while turning a corner. I checked the oil level to which I needed to add three quarts to bring it back to normal. We have 20,000 miles on our car. This seems to be a lot of oil. There are no oil spots or drips under our car and no smoke is coming out from the muffler. Engine bay is clean. I searched online and found many other new Jeep owners with the same complaint. Is anything being done about this?.
