1 Electrical System problem

Failure Date: 11/24/2020

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.

2 Electrical System problem

Failure Date: 09/11/2020

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.

7 Electrical System problem

Failure Date: 09/24/2012

1st time vehicle wheels and steering completely locked up when making a right turn blocking traffic and had to be towed after police and no one could release it. 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. I sent a letter to gm reporting the problem and the repair that was done, but I am very concerned that there may be other vehicles on the road that could end up with many deaths. And I am not confident that my problem has been solved.
