2005 Buick Rendezvous Engine problems

I bought my car from a used car lot. I had it about 3-4 months and out of the blue it overheated very quickly, the warning light was on, some type of loud buzzer was going off so I pulled over and let it cool off, it took about 45 minutes but it started back up. I checked all the fluids and coolant levels and everything was ok. This continued to happen for about 3 weeks, quickly overheat, lights, alarms pulled over, checked fluids over and over. After about 3 weeks it would quickly overheat and then shut off on its...

Rear wheel bearings failed at 30k mi. Cooling system failed at 110 k mi. Car in motion on highway.

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!

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 1600.00. 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...

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 fianc were almost hit in an intersection because of this loss of power. You can...

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...

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. *Tr

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. *Tr

I took my car to the local gas station about 3 minutes from my house. I went in came back and out and before I was even halfway home my car started to overheat. I hadn't even driven half a mile. The thermostat and the coolant temperature sensor have been replaced and the radiator flushed. There was all sorts of brown gunk in the line but the issue still is not resolved. The heat only works occasionally after this and the car still will run hot and then drop back down to a normal temperature all within 2 minutes. No one is sure of what is going on with it. The cause cannot be found at this point. *Kb

My 2005 buick rendezvous would periodically stall in turns or at red lights. 1 Instance it wouldn't start again and it had to be towed to a buick dealership. They said they fixed the problem with a new battery. After that it would still stall at lights and intersections. I told various mechanics about this problem. They would look into it and never found a problem. I even had my fuel filter changed etc. Well, on january 21 2011, I was making a routine left hand turn into work across 2 lanes of traffic when my car stalled... It wouldn't pick up and go. I was then hit hard on the passenger side totaling out my vehicle and resulting in minor injuries on both parties. *Tr

2005 Buick rendezvous stalling. On 4 occasions to date this vehicle has stalled on me. The first time I was going 70 mph on the highway and it just shut down completely. I almost was rear ended. I managed to get it to the side of the road. It started back up. The next time I was in a school zone going about 10 mph turning a corner and it went dead. It started back up. The third time I was slowing down to stop at a light and it stalled. It started back up. This is very worrisome and I would hate to think of the accident that could happen due to this. *Tr
