Starting sometime at the end of October 2007 into November of 2007 my 2002 Buick Rendezvous started having starting problems associated with the security system. Vehicle would intermittently not would be hard to start or not start at all. If jumped off the alarm system would go off. Sometimes the radio would not come on, A/C would not come on, lights would flash, etc. In late November the vehicle finally went haywire and started blowing the horn, lights blinking and lights not going off after vehicle was turned off. Disconnected battery repeatedly to reset until that would no longer work. Took it to the dealer to have it checked. Was told it was the BCM. Had BCM replaced and reprogrammed. On March 14, 2008, vehicle started doing the same things that lead up to this part being replaced. Am taking it in again this week if I can keep it started. Doing this complaint because after reading various internet blogs, forums and chats this problem seems to be a recurring problem for many 2002 Buick Rendezvous'.
