2000 Pontiac Bonneville with 32,000 miles. The drivers side rear door window dropped out of track while driving. I do not use the rear windows and it was in the up position and not in use. So far I have taken it to a body shop and had them prop the window up temporarily. They advised me to get it fixed because of fear the side air bag May be affected by disconnecting the power to the window. I called the dealer in our town and asked if there have been others with this problem and they said not that they were aware of. I was told they don't sell the track separately from the whole assembly including the motor and the cost of parts would be at least $350.00. I know of another owner with the same year and model as mine and both of their rear windows did this in a matter of days of each other. He lives in my town and this makes me think it must be a widespread problem. …
I have had my 2000 Bonneville in the shop several times for various reasons. My radio had to be replaced, my drivers side window stopped working and they replaced the motor, now my passenger side window does not work and needs to be repaired. My trunk leaked and was told the extended warrenty did not cover it and the expense was on me. My air conditioner would blow cold air and then hot air or not blow cold air at all, it was in the shop 2-3 times for that. Now my car hesitates when speeding up and you can feel it jerking into gear when it shifts between 1st and 2nd gear or 2nd and 3rd. For this reason I had my transmission fluid replaced and an additive put in and was told this should take care of the problem. It has not!! My next step is to take it back to the dealership to find the problem. Is there anything I should know about concerning the transmission jerking, recalls,etc..?
The motors for the windows in my vehicle are an engineering defect. The motor for the drivers window went out. I've never had a motor for a window go out before however I know it does happen and I do use this window probably once a week or so. The problem is that I use my car for work only and all my children are grown. Both back window motors have also gone out and total for the back to windows they have been rolled down 5 times only by accident when I was intending to roll down the drivers window. At $350.00 to repair the back windows have been made to stay permanently shut. I don't think it would be very safe to have all the windows made to not roll down but it is agrivating that I should have to pay for their poor design.
I purchased a GM certified 2000 Pontiac Bonneville in May 2002. Since that time I have had to replace 3 window regulators in the vehicle, one for the drivers door and one each for the back doors. This seems to be quite excessive for a vehicle that is only 5 years old & has less than 80K miles on it. Further, I have a small child so I can count on one hand the number of times that I have lowered the rear windows. I am confident that this is not a wear-and-tear issue, since I have replaced both regulators with GM parts and as I stated seldom roll the windows down. I have noted an approximate date for the first incident below. The most recent replacement was in August 2005.
July of 2005 left front window regulator failed. Replaced window regulator. November 2005 left window regulator failed. December 2005 right window fell down while driving because regulator failure. Car has air conditioning and windows are not used much. Rear window switches are locked out from drivers control because of a child in back seat. Reason for not being used much. I only have fixed the drivers window because of the expense and need to pay tolls. I have contacted GM about covering the parts and I will perform the install. They refused because of the 100K miles. This car is a 2000 Pontiac Bonneville.
1. Right rear window motor failed at 30 months, but 60,233 miles. Window had been raised and lowered less than 25 times. Pontiac agreed to 40% reimbursment. 2. After 60K mi check up, car began shifting very rough. Service engine light came on at 63,266 then off,no problem, again at 66237 in shop now, with two trans diagnotic computer msgs. Will not know cost until problem found. Before dealer did 60K check up was getting 29 mmg on interstate, since check up, getting 23-25mpg on interstates. I believe direct correlation between two, but I know dealer will not agree.
I've had 8 failures where the power windows fall down without warning. The first two failures were under warranty. Since then he regulators had to be replaced at a cost of $200 to $250 each. I stopped using the power windows years ago but they still keep breaking. On the last two occurrences I glued the windows closed with construction adhesive. Probably not the safest thing to do but I'm done paying for a factory defect. One broke and fell down when the door was closed, five broke and fell down while driving and two broke and fell down while the car was parked.
Bonneville with 37,000 miles. Numerous problems worst being upon attempting to make a right turn car keeps going straight then a clunk is heard from the front end of the car and the car finally goes right. This happened more than once. Dealer was also able to get the car to have the same problem. Dealer finds some type of metal lodged in between the links on the rack. Rack is replace under preferred warranty. Car has been in the shop 3 times in the past 14 days for a rear window seal leak, and is currently in the shop for a catalytic converter problem.
Tl contact owns a 2000 Pontiac Bonneville. The contact stated that the rear driver's side window will not go up or down. When he attempts to open it, the window does not move. The window automatically goes down when driving over a bump in the road. The contact took the vehicle to the dealer because the failure previously occurred on the front passenger side window and he was charged $409.41 for the repair. As a result, he will not pay to repair the window again. The failure mileage was 88,800. Updated 10/16/08 updated 10/21/08.
Within a months time I have had to replace both rear window regulator assemblies in my 2000 Pontiac Bonneville. The first window went down on its own and would not go back up. Less than a month later, the other window did the same. I took the car to a local dealership on 2 separate occasions to have this fixed. These parts are very expensive. I find it odd that a 5 year old car with only 60,000 miles should have such a problem, especially in such a short period of time. Could you give me some insight on why this could be.
