This is a great looking SUV. Really love the style. It has had a multitude of electrical problems plus leaking gas lines. The ECM computer has issues that are too many to mention. Quoted 1600, to fix by dealer. If you replace the computer you have to have the dealer flash it. They won't do it unless I have the work done there.

Rendezvous Ultra 3.6L-L Ohv V6

  • Automatic transmission
  • 41,000 miles

We've owned this car for 10 months, and this is the 3rd major issue we've had. I'll be posting the others as well, but I'm pretty sure all 3 are known issues. In this case, we went to turn the car on (at the airport @ 1:00am) and it wouldn't start. The odometer read 'error', the fuel gauge read nothing (even though we had 3/4 of a tank in it) and it didn't even try to turn over. Had it towed to a Pontiac dealership and after telling us the car was "kicking their butts" they fixed it by replacing and reprogramming the ECM (when they first replaced it, it wouldn't recognize the car)

All in all it took 4 days to get it fixed, cost us a cab ride home after our vacation, along with towing fees. Do yourself a favor, don't buy a GM car
