One problem related to starter has been reported for the 2014 Jeep Wrangler. The most recently reported issues are listed below.
Randomly the instrument panel gauges would go crazy, the "idiot" lights would come on, and if the cruise control is on, that will disengage. I've had other incidents where the vehicle would not have any power when the key was engaged, until 4 different times of trying it. Also when starting the engine, the starter would continue to crank even with the key disengaged.
