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.

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.

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.

I write to report an occurrence of uncontrollable acceleration in a Buick Rendezvous. I rented the current model year Rendezvous from avis at lax airport on 5/14/05. That evening as I was accelerating to get on the freeway, the car accelerated uncontrollably. I immediately took my foot off the gas pedal, and put both feet on the brake, yet the car continued to accelerate. I noticed that even with both feet on the brake and pressing as hard as I could, the speed was increasing. Fortunately, at the on-ramp where I got on, the traffic was light, and there was approx a half mile where there was no traffic in my lane. I pulled to the right and was getting ready to turn the key off, since I could not otherwise slow the car down. After a total of 8 " 10 seconds, the throttle went back to its normal condition ? ie the run away acceleration ceased. I spoke to the return agent at avis who assured me the car would be taken out of service. I write this note to make sure that avis knows what the problem was. I certainly could have caused an accident if there had been other cars near mine.
