2007 Buick Lacrosse: engine stalls while driving

Filed Jun 6, 2025 · Electrical, Lights · OH

Low beam headlights randomly turn off while driving at night and day. Causing not to be able to see the roadway at all. Very dangerous!!! They give no warning at all. Only the low beams do this. Bright lights are not affected. There was a recall for this issue but they said my car was not affected. But it is 100% affected by this recall. Ot seems like the Headlamp driver module is overheating. It gets extremely hot. This issue almost caused a very serious accident .

Taken car to dealership for computer analysis and was told that the issue was caused by P0420cataylic converter needed to be replaced. I had cataylic converter replaced elsewhere and noticed that wasn't the problem. After doing some research I found that ignition switch is the reason my car stalls while driving. There was a Product Safety Recall (14299) Ignition key rotation and replaced on 10- 8-20 but I'm having the same problem.

We were stopped at a red light and the car just died. We called aaa and before they got there the car started up again. Then we received a recall notice from gm (recall #14299). Since parts are not available according to the letter we removed everything from the keychain leaving only one single key as instructed. However, our car again died on august 21, 2014 but after a few minutes started up again. Today, august 31, 2014 our buick died again in the left turn lane stopped at a red light. We had to be towed home by aaa because it would not start again. This is unacceptable!! We are an 80 year old couple and we only have this one car for transportation. We cannot keep worrying about our car everytime we drive it, much less the dangers of having an accident when it stalls in the most unexpected places and times. We need a rental car to use until gm can get these parts. I don't think that I am asking too much.
