66 complaints about the 2004 Buick Regal

Newest first, as filed with NHTSA by owners. Page 1 of 3.

Electrical system

All 4 power window motors do not work. They all failed within 6 months of each other. I checked on you tube and found that almost all buick regals have this problem of power window motors breaking. There are hundreds of complaints on you tube alone for this issue. I believe this is proof that the power window motors are defective and probably made this way to force owners to make expensive repairs. I am asking you to force buick to recall their regal models and have the window motors repaired at buick's expense.

Electrical system

The first time the car stalled was as I was approaching the stop sign.It stalled and the dash light all came on. I was able to re-start it after putting it in park. It then happened again the same as before I got home. The next day it drove normal for awhile then as I was starting it up again it started with a noise and the lights on the dash a lit up again. It seemed to run normal again. But a bit later as I was slowing down to make a turn into a parking lot it stalled again. I brought it into an independent automotive garage and they hooked up to their tester and could not find anything abnormal with the car.

How long does the nhtsa allow gm to fix recall 15757? It appears that gm is just waiting consumers out because of the age of vehicles, i.E., Affected units are probably being taken out of service and the longer gm waits, more of their responsibility naturally goes away. I called the buick recall hotline and they stated that they had no idea when a "fix" would be issued.
