When turning,the engine quits. 2003 Buick Regal I am mechanic found the ignition switch weak and when you engauge turn signal switch the engine stalls.
At night if the high beam lights are on, and I meet a vehicle while moving through a right curve, the dimmer switch cannot be activated because it hits the back of the steering wheel. Since this occurs almost every time I drive at night to go home, I'm afraid it could blind another driver and cause an accident. I have gotten bad reactions from other drivers when I can't dim the lights and meet them on the road. (I don't want to be the victim of road rage. ) I have experienced this problem since I bought the vehicle in 2004. The switch broke a few years back and it was replaced, but the new one still had the same problem. The dealership said that was the only model of switch in his catalog. It has a design flaw. It the turn signal handle was designed to be push away from the steering wheel instead of pulling it toward the steering wheel, there would be no problem.
