Vehicle overheated to the maximum, then it stalled. I waited a bit and was able to restart it. The temp. Returned to normal. While continuing to drive home at 35 mi per hr. It stalled again, and I was able to restart it, and make it home. I phoned my mechanic, and had it towed there. He informed me there was water in the exhaust which indicated expensive head gasket problems. He suggested I sell this vehicle asap. I had only owned it 2 months! when this problem occurred I was in motion at 35 mi per hr. On a city street. Very dangerous!

One day I was on my way to drop of the kids at daycare when the care suddenly turns off, I was going at least 60 mph;I was on the highway. Thank god nothing happened, I was able to pull over safely I waited for a while then maybe 15 min later it turns back on.I started to notice that the car started smelling, like gas, I took it to the mechanic, several times but they never could figure out what it was. After that incident it went down hill it started to heat up on me, wasted more gas, would turn off on me a lot and air/heat stopped working. I replaced the transmission because it started to slip, thinking that it will fix the problem and boy was I wrong. It was still doing the same, the smell was getting worse, I took it back to my mechanic. He told me that the head gasket needed to be replaced, I didn't have more money. He did't let me drive home, he was very worried because the smell of gas was so bad, he said that I should risk my kids and myself, the care can catch on fire. He had the truck towed to my house didn't charge me for it and I haven't moved it since then..ive put so much money in that truck, I kept up with the maintenance like clock work. I was just lucky that we never crashed we got close and we didn't blow up. I don't know weather I should take it in to a GM dealer to have them evaluate the truck to see if it is part of the recall.

We found out that we had a problem with my wife's vehicle. Initially, the vehicle was stationary. I took it to get an oil change and was asked to come into the shop to be shown that the antifreeze was like yogurt in the reservoir. We were told that we needed a coolant flush. This led to being told that we needed a new radiator; bypass hose; and last but not least, head gasket job amounting to approximately $1600. We were told that there was no open recall but yet there was litigation going on regarding dex-cool antifreeze and that it was causing all of the problems that were and are having with this vehicle.

On, Thursday, July 9th 2005, I tried to start my vehicle, it started but the ignition seemed to keep trying to start. None of the start up lights worked (oil, brake, service engine, seat belt), so I knew something was wrong. I turned the engine off and tried restarting it and it wouldn't start. I kept trying to start it for about 10 minutes. I finally gave up and went inside. I came back out and tried to start it again about 15 minutes later and it started up just fine and everything was working inside. On Monday, July 13th 2005, I tried to start it and nothing happened. I waited about 10 minutes and it started right up like nothing was ever wrong. I feel like there's a problem with the ignition somewhere. I'm afraid of what will happen if the car stalls while I'm driving it. The ABS seems to come and go as it pleases as well, I don't know if there have been any complaints about that.

Intermittent loss of power, loss of ABS brakes and loss of AWD. When you apply pressure to the gas pedal (accelerator) if you depress the pedal for what feels like over a 1/2 inch you lose power and the rpms go sky high and you can hear it trying to rev up. To get going you have to release the gas and press lightly. I loss power, esp. Going uphill since it needs more to go, but you can't give it more gas else it won't go. I and my fiancé were almost hit in an intersection because of this loss of power. You can gain speed, but very slowly and anytime you depress the gas pedal further it again fails. Replaced three wheel bearings, all brakes, two calipers and the throttle position sensor. Nothing shows on the readout except for the front bearings aren't reading right, but they're brand new and have been re-checked for defect. Still that hasn't fixed the issue. Upon problem has actually been occurring for almost two months now.

The car stopped automatically at a stop light on a major hwy. I thought quickly and put it in neutral thank you jesus it started. I could have been rear ended. That is a major problem it does it periodically. I never know when its going to do it... I have replaced the wheel hub assembly on the rear 5 times and 2 on the front.. my gas gauge goes crazy or doesn't work at all. My speedometer has quit working and the other gauges work when they feel like it. It seems. I have had people check the vehicle out no one seems to know exactly what is wrong they say the cluster is out because of the gauges I don't have $900 to fix it. I am always putting wheel hub assembly on it. That gets very expensive..

When turning into my driveway the engine shuts off losing all steering. This has happened several times in the past (since 2009) usually when turning right from a stop sign or turning right into my driveway.

Rendezvous 6-cyl

  • 81,000 miles
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.
