One problem related to exterior lighting has been reported for the 2005 Buick Rendezvous. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2005 Buick Rendezvous based on all problems reported for the 2005 Rendezvous.
Update: prior issues were due to bcm failure which that was my assumption based on numerous owner reviews. This part is a major safety issue if fails and Buick is aware and won't recall. These should last for the life of the vehicle. Occasionally one will go bad but shouldn't. The fact that many Rendezvous models face this issue of failure prematurely shows that it is a defective product! many have almost dies due to this failure. Car shutting off and lights going out while driving down highways/ expressways.
