One problem related to car will not start has been reported for the 2016 Jeep Compass. The most recently reported issues are listed below.
Vehicle will without warning stall in the middle of driving, in city traffic, on country roads, starting up a hill as well as driving on flat straight road. I've been driving 55mph, 45 mph 25 mph and it will stall, the traction control light will come on. Sometimes the car will not restart for 10+ minutes after stalling. Each time I was driving in traffic, and had children in the vehicle with people behind me. Engine just cuts all power, power steering is lost. Also have noticed a huge drop in fuel efficiency, used about 1/4 of a tank in 30 miles, acceleration and vehicle not shifting normally. This is the 6th time in two weeks it has stalled, and 2nd time to take it into the dealership with this issue. I've only had about 6 months, it was cpo and have driven it about 10,000 miles.
