One problem related to crankcase (pcv) has been reported for the 2010 Jeep Wrangler. The most recently reported issues are listed below.
Vehicle is consuming excessive oil. I check the dip stick every time I get gas to be sure it doesnt go dry. It started being very low at just 3,000 since last oil change and progressively got worse. The dipstick will now be below the safe line at 1,600 miles since last oil change. I have had the pcv value replaced and it didnt not fix the problem. I have been to several specialty Jeep machines who have said I will need a new engine.
