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'.

Our 2002 Buick Rendezvous began acting up shortly after purchase. Once when it happened, we called the Buick hotline number on the window sticker & the onstar people. Buick guy said sorry not under warranty & a certified center would have to look at the problem as it was happening. Onstar couldn't offer any advice. When the vehicle was taken to Buick for a recall/latch repair, we asked about this problem & were told unless they saw the problem right then they couldn't help. Obviously, I was driving the car & it was starting and running like it should. The problem: Pulled into a non-Buick garage to get vehicle inspected. When mechanic was done he pulled the car out of the bay & parked it turning off engine. I got in to leave & engine cranked but wouldn't start. This happened before in our driveway but we thought it was a fluke. The mechanics couldn't figure it out so we left it there for them to work on. When staff went to start the car an hour later it ran just fine. Another time, my finger slipped while turning the ignition key so I went to turn it a second time. The car would not start, or if it did it would stop, as if choking out & not getting gas to the engine. I tried several times then gave it 30 minutes to sit & it then started. Another time we pulled up to a gas pump, got gas, got back in, & the same problem...had to let vehicle sit where it was for 20 minutes without cranking the ignition then it started fine. Again: On a weekend while shopping, pulled into a parking space & cut off the engine; realized needed to go to the bank first & when attempted to restart the car, it kept shutting off. Now, finally, I am very lucky if this car will start at all. Took it to my friendly garage, thinking it needed a new starter, & they cannot find the problem. Am now on my way to a local Buick service center, which will no doubt cost me an arm & a leg for something it seems like has been problematic with this vehicle since purchase!

After running for a while if you shut the vehicle down and try to restart it within minutes it doesn't always want to start. The first time it happened I had the vehicle towed to the dealership. It was afterhours, so it sat overnight. The next morning when the service dept. Checked the vehicle it started right up. They put it on the computer and found no problem. The problem has happened 3 more times since then. I just let have to let the car sit for upto 30 minutes and it will start up again. I spoke with GM and they said there is really nothing they can do. The dealership can't duplicate the problem and therefore can't find a solution.
