Three problems related to starter have been reported for the 2009 Jeep Wrangler. The most recently reported issues are listed below.
The vehicle has some type of short in the starter circuit, so power does not transmit to the starter when the key is turned. This is a common complaint on jkforum as well with a solution of adding a ground wire.
Started my car with the remote starter. Everything from wipers to alarm to window washer to lights went on a fritz. Smoke came out of the hood. I made sure car was turned off and opened the hood to discover a fire. I had a small fire extinguisher and was barely enough to extinguish the fire. Once extinguished I called the dealer who had just serviced the car and am waiting for an idea why it happened. It melted the electronic components next to the air dam, wires around the battery etc.
The contact owns a 2009 Jeep Wrangler x. The contact stated that the vehicle failed to start after several attempts. The engine restarted after three hours and resumed normal operation. The failure occurred twice. The vehicle was taken to an authorized dealer for diagnostic testing. The technician was unable to duplicate the failure. The failure mileage was 2,000.
