One problem related to power train driveline has been reported for the 2003 Jeep Wrangler. The most recently reported issues are listed below.
I have an 03 Wrangler, yellow that has the paint chipping off in several places. This vehicle has less than 8k miles & is never taken off road. These are all inner city miles. I have been advised by 2 diff dealerships that this is caused from bugs! this same Jeep has also had driveline problems. So much for a heavy duty off road vehicle.
