Dash lights lit up, bells, battery light on/off until car stalled. Mechanic said alternator and battery. Did it again next day so far 800$ still not fixed. 2 alternators, 2 batteries, also said it was a short that was fixed. not done, should I try new mechanic or sell it for parts? also gas gauge does not work, smell of gas with heat on. I bought it used with 150000 miles and put 7500 miles on it. I'm on disability sick from working WTC ground zero. I can't afford this. never buy a rendezvous. I have heard all bad, not good, about this car.

Power Input and everything is ok alternator is charging . But I till need another battery 4th one within 7500 miles I hope that's it I paid total so far 800$ and I figured it out myself I realized now that they are many more problems I noticed horn goes off radio turns on by itself when car is off and parked dash lights don't work sometimes radio lights off and on traction control does not work check engine light shoes no code when on . Don't buy one.

Update from Sep 22, 2014: Car still having problems dash lights and gauges killing batteries alternator not fixed yet

I bought this lemon 6 months ago and it has given me nothing but problems. The first week I received it, my car died in the middle of the road, the next day I had the battery replaced. The next week I was at a store and when I entered my car, it would not start. I had to call a repair shop to have it towed and repaired. They said my fuel pump needed to be replaced, $700. Two months ago my AC stopped working, only blows hot air. Still have not repaired that problem.

Now my car goes haywire when I drive it where everything goes off and on, my door locks, my windows stops working, my radio shuts off, and my battery light comes on. I took it to a shop and they said it was something with the power, paid $325. After 2 weeks, my car is doing it again. I am afraid to even drive my car because I know it will just shut down on me or will lock up on me or leave me completely stranded. This car is unsafe to drive and being a single Mom of a baby, scares me so much.

I think GM/Buick needs to take responsibility and call this a recall since it is happening to 100's of people. Why should we continue to throw money into a car that is faulty do to their error in building them. This is why American cars get a bad name. Please help!

The security light came on, radio wouldn't work, lights wouldn't shut off, or the lights and radio stayed on. The positive cable had to be disconnected and rebooted. I finally replaced the BCM. There has been similar problems and than the drivetrain. The windows all wouldn't work. It was put together with plastic parts. The rear window wiper wouldn't shut off and finally fried itself. Never worked again! I would never own another one. The loaner I used also had a problem with its AWD light shutting off.

There should have been a recall on this car but Buick is too cheap. I have a friend that replaced all his wiring in his Rendezvous. Good Luck Rendezvous owners!!!!
