2001 Pontiac Bonneville: power window failure

Filed Nov 9, 2010 · Visibility · 52,000 miles · ME

First incident happened when I was just driving to work I went to lower the rear window heard a noise and the window fell down. I tried to shut it, but it would not close, the motor did not work and I only had 52,000 miles on the car. Second incident happened last week when I was driving to the store with my baby granddaughter and the window on the other side did the same thing. Difference here it was a cold day in maine and my 16 month old granddaughter was in her car seat in the back. Tried to get it closed but it would fall right back down. I had to get the parents to come get the baby because it would have been to cold for me to drive her home with the wind coming through the window I now have 62,331 miles on this car. This is very unsafe, all 2001 bonnevilles should be recalled, and have the windows fixed.

Tl*the contact owns a 2001 pontiac bonneville. The contact noticed coolant leaking underneath the engine compartment. The vehicle was taken to the dealer and they replaced the intake gasket, valve cover gasket, oil pan, and several piping components at the cost of $1,400. The repairs were made at the contact's expense; however, the vehicle continued to leak coolant. The dealer stated that the contact should not be concerned. The contact later took the vehicle to a different dealer and they found that a coolant elbow pipe had been knocked out of place, which caused the leak. The necessary repairs were made to the vehicle for the second time at the cost of $10, due to the failure of the initial dealer. The failure mileage was 93,767 and current mileage was less than 105,000. Updated 07/08/09 *bf the front passenger electric window motor failed and needs to be replaced for a second time. Updated 07/08/09.

When the rear window motor of 2001 bonneville fails, it causes the window to lower even though it is in the fully raised position. The window position was not being changed at the time. It was just a sudden clunk sound from the back seat and the window went down. This happened when driving at night in very heavy rain, on the interstate with infant in the rear seat. This may seem like a minor item, but if we had been in a north dakota snow storm, temp. Of 5 degrees and wind chills even worse.. The situation would have been life threatening. The window should be designed remain in it's selected position in the event of motor failure. The second rear window failed in the exact same manner about 4 months after the first..no baby on board this time.

Both rear windows have fallen down (at separate times) without operation by driver/passenger. Approximate cost of regulator/installation for repair = $350-400 each. First incident (rear passenger side) occurred, and I taped up window pending repairs. Tape came loose, and window fell down again during rainstorm. I was alone in car, and had to try to find location on highway to attempt to get window back up. Safety issue with being on shoulder of highway during torrential rainfall. Window is still taped because once the second window fell, cost became too prohibitive to fix at this time. Second incident (rear driver side) occurred approximately 2-3 weeks after first incident. Granddaughters were in rear seat, (window locks were on because 1st window had already fallen), granddaughter gave small scream of fright when window fell, surprising my husband (driver), causing him to jerk wheel in traffic because her scream caught him off-guard and he didn't know what had happened. Second window is still taped. Safety issues with children in rear seat and window down, with no way of putting it back up at that time; plus, the unexpected fright to driver.

Rear window regulators have both failed, allowing the rear windows to drop and cannot be raised. The only way to fix the problem is to replace the regulators ($350.00 each). Both passenger and driver side regulators have failed. This is a well know (both by owners and by gm) problem on pontiac bonnevilles. This is a safety issue, since the rear windows do not raise, they pose a risk to passengers in the rear (especially children), who can be hit by debris entering the windows, cold air in the winter, or children putting arms or head out and being injured.

Dt: the consumer was driving home from work and the back driver's side window fell down in it's window slot halfway without any indication. The driver heard air and wind coming into vehicle and discovered that the power window had opened halfway by itself. The consumer took the vehicle to the dealer who replaced the window regulator which failed. Afterwards, the front driver's side power window has failed and the window will not go up by itself without manually helping to maneuver it back up. There is a grinding noise. The second failure has not been repaired or taken back to the dealer as of yet.

If this is not where I need to send a complaint, please forward this message to the correct persons. I own a 2001 pontiac bonneville with only 52,000 miles. I bought this car in may 2004. *ak in june 2004 the power window went out. I was informed that they could not just replace the "arm" but also the window motor with a cost $300. Then, only 3 months later the check engine light came on and I found out that the ignition module went out which made the ignition coil go out, which made the ignition cables go bad! That was an additional $650! The reason I am upset is because carmax supposedly have their cars "carmax certified". They are supposed to protect against getting a "lemon".

I have a 2001 pontiac bonneville. The air bag warning light displays check air bag. The dealer says it has to be replaced for $650. The same day the left rear window fell down and the cost to repair is over $500. Neither the airbag nor the window have ever been used. The car has never been in an accident or off the road. Two parts failed for no reason.
