One problem related to crankcase (pcv) has been reported for the 2018 Jeep Renegade. The most recently reported issues are listed below.
I had purchased a brand new 2018 Jeep Renegade trailhawk and before it had even reached the appropriate mileage to bring the vehicle in for its first standard service, I had discovered the engine was burning an excessive amount of oil. The vechile has stalled on me before while the car was in motion and whilst driving on busy highways. I have made multiple complaints with the dealership and made attempts to have the issue corrected (oil consumption test, replacing the pcv valve) and yet the issue still exists. Jeep staff members through the dealership along with members from Jeep headquarters keep attempting to inform me "it's normal, just keep putting oil in it. . " I am not satisfied with this response. I do not feel safe driving this vehicle. It is not only hazardous to myself as the driver, but also the public when the car does stall.
