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. …”

“The driver's door window master switch became inoperative. I had to replace it. You have a notice on the 2006-07 Buick rainier but the 2004 Regal should be on the list. I think the list involves several more Buick models. This problem occurred when the car was parked or in motion. In my case the window would remain in the open position whenever the ignition switch was on. I was not able to close the window. I replaced the switch myself as I did not know about the recall.”

After having towed the vehicle to my home. I was able to release the lock and tested it before I decided to drive it to a gas station for gas. As I pulled out of the gas station the vehicle locked up again blocking two lanes of traffic coming at me on a 4 lane county road. …”
