The headlights, dashboard instrument cluster, and radio, cd player, interior lights, and tail lights on my 2002 Buick, Rendezvous kept going out for no apparent reason while driving on the freeway. I took the car to the shop and they said it is the body control module. It is my opinion that this malfunction is a very serious problem. In my situation the several times that the lights went out, I was in a dangerous place (on curvey highway between pennsylvania and ohio at speeds between 55-70mph) the situation when the headlights and dash lights were out could have had fatal consequences especially when tall hills surround curvey freeways and roads and such as a deer crossing the road or worse yet, a person on the side of the road. The problem is still occurring and the bcm keeps malfunctioning every few minutes turning off all lights and dashboard clusters and it costs too much for me to fix-almost $1400.
