When I am driving my vehicle will just stall. If I do not let my car run for at least 5-10 minutes before I go anywhere it will stall out on me not long after. It has stalled on the highway, even a few times with my 6 year old in the vehicle. After it stalls out a lot of times I have to park it, turn it off, open my door/shut it, then wait for the inside light go out before I try to start it back up. It does start back up after I let the light go out but not everytime. I have sat there for 30 minutes to an hour more than 3 times. Now i do not have control of any of the master controls for the windows or locks. I have to lock my door manually now. I was told that it could be from my ignition switch which I know there was a recall on before. I would like another recall for this issue and for it to be fixed before something not so good happens.
I was driving down the road about 1 mike from my house. The road is a country road and is straight. I wasn't distracted or speeding. It happened so fast but I think I May have hit a slight bump on the right hand shoulder of the road and then the car started fish tailing and then went off the road and was stopped when it hit a dirt driveway. I had no control of the car and the brakes failed to stop the car. The car was totaled with only 36000 miles on it even though I luckily just sideswiped a tree. The car always seemed hard to steer as if the steering was loose and you really had to pay attention and keep both hands on the steering wheel. The car was my elderly in-laws who bought it brand new in 2007. They both passed away in November 2018 and then I inherited it and had just recently started driving it. The air bags did not deploy.

Head light failure due to passenger side relay harness module failure. Low beam lights failed on dark night on mountain road. This problem has been reported by numerous Buick Lucerne drivers. Buick obviously knows there is a problem because they offer a replacement front light harness module that must be spliced into the existing main light harness to replace the original equipment module. This is an obvious manufacturing design defect and a difficult module to replace. The replacement module is approximately $50 and the replacement labor is around 1.5 hours. With normal use this light module connections shorts out because of the overload on the module. Why hasn't this problem been considered for a recall? GM has admitted it is a design defect with the availability of the replacement light harness module wiring kit. My wife almost went off the road and wrecked when the lights went out.
