Within a month both of my rear windows quit working. Instead of spending a crap load of money we took the door apart and clamped the window so it would not fall down. Then soon after our gas gauge quit working (so now we keep up with mileage).Now there is something wrong with our drivetrain (we have replaced passenger axle, bearing assembly, new tires and an alignment) and it is still not fixed. The car vibrates so bad it sounds like the dash is going to fall in your lap. And nobody seems to know what is wrong with it. This is the last Pontiac I will ever own (anymore I think I would rather ride my horse to the grocery)

I have a 2000 Pontiac Bonneville SE with 98000 on it. I have replaced the drivers door window regulator and the right rear passenger in less than 2 months of owning this vehicle. This is the first GM product I have owned. It probably will be the last at this rate. I have spent more than $900 dollars on repairs to the windows and have done the work myself to save costs. I went through three after market window regulators on the drivers side and am crossing my fingers on the fourth. This is a terrible design and GM should honestly look at the problems people are having. I'm sure the folks on the higher side of GM are still collecting their profits at our expense. GM if you care about people and your product check into this and be honest. I know vehicles need repairs but this is getting to be a joke!!

A little less than a year ago my driver's side window regulator went out. Last month my passenger side went out and guess what? Last night my freaking rear left one went out too. I am so freaking pissed right now. The hell if I am paying 300-400 to fix this, it is OBVIOUSLY a factory problem. I found some after market regulators on ebay but it is still gonna cost me $218 just to get the parts. I'm gonna try the epoxy like that guy said before and if that doesn't work I'm gonna throw a sh*t fit with Pontiac. UUUUGGGGGHHHHHHH I'm so disgusted!!

I had a total of 3 window regulators break within 1 month of each other. I could only afford to have one replaced at a cost of $365.00, unfortunately the window is not aligned so it still doesn't work. When I spoke to the dealer I was told that there was no reported problems, however after I got the car and it was under warranty at the time my back window regulator broke and was fixed. However, the other 3 waited until the warranty ran out. I have the windows propped up with a clamp. I also had another bonneville that the same thing happened. Not a problem Pontiac???

Have replaced each window cable twice and starting on third round in back. My dealer says there are no reported problems that he knows of with these window motors/cables. Well, he will be given this website to read! so glad I found it as I thought I was the only owner with this problem. 5 times while under warrenty and I have paid for 4 myself. I am going with the epoxy fix before another one breaks. In the shop now to replaced a/c compressor and hose, bad shocks, some sensor to stop surging problem. This is the first and last Pontiac I will ever own. Have never had these kinds of problems with my Chevys or Buicks.........

The back window broke off it's track while raising the window. Since it was out of warranty I took off the door panel and inside I found A TREE BRANCH!!! It has to have been put in at the factory because the door was sealed with plastic. I called Pontiac Customer service and was told it was not under warranty and they wouldn't fix it. The service rep actually laughed at me. I guess pranks from the factory are funny to them. They will never again hace the chance to laugh because this is the last pontiac I will ever own. I will also highly discourage anyone else from buying one.
