My 2005 GC SXT has 1179 miles on it and just came back from its second multi-day stay at the dealership. At 500 miles the instrument panel went dead due to Body Control Module (BCM) failure. This included the following: a) instrument panel dead including no odometer changing with driving b) headlights default on regardless of headlight switch position c) no windshield wiper function d) no A/C function e) no power door functions
This condition remained constant until after the car was parked overnight. In the morning all functions returned but the Engine Service light was active. The dealer read out the OBD port multiple communication failures. Chrysler instructed the dealer to replace the BCM which took several days to arrive. I filed a safety complaint with the NTSB for windshield wiper failure.
Two weeks later the condition repeated itself only the functions reset themselves immediately resulting in Engine Service light activation again. The Engine Service light remained active for several hours (driving + non-driving) and then went out. The dealer read the OBD port again showing the same failures. Chrysler instructed the dealer to flash the BCM with TSB 08-028-05.
I'll see how long this last and whether it really fixes the problem. Out of 3 new Chrysler vehicles I have purchased since 1997, this is the second one with catastrophic problems. Chrysler Customer Service was useless both times. The first vehicle was voluntarily replaced by the dealer when the camshaft broke at 1000 miles and the engine seized. I will never go through this hassle again. No more Chrysler products for me.
