One problem related to wiring has been reported for the 2002 Chrysler Concorde. The most recently reported issues are listed below.
From the time of purchase we noticed the interior lights flickering. This could occur while driving, while parked, and even while the car was turned off at night. The car's alarm would also chirp when the car was off. This has continued, and progressed to the battery draining if un-driven for over 12 hours. We couldn't get any of our mechanics to take an interest in the issue. They couldn't offer any suggestions. When having a minor accident repaired, a mechanic suggested a problem with the wiring harness.
