Driving to work in the mornings recently, I have been having some electrical issues with my car. If I use my blinkers, all the warning lights in my dash cluster will light up for a few seconds, and I could feel my brakes pulse. This morning my car stalled when I made a right hand turn. I managed to pull over and restart the car, but I didn't use the blinkers again. This really scared me, as I was just on the freeway a few minutes earlier.

On multiple but intermittent occasions, when the left turn signal is engaged all dashboard warning lights flash and the vehicle stops running. I was fortunate in that it never occurred in heavy traffic, but it still represents a significant danger. On one particular occasion, it failed to restart and I had the vehicle towed to an authorized gm dealer who kept it for seven days but failed to find or fix the problem. Instead, they replaced "broken and loose connectors on the fuse box." when the problem recurred two days later, I returned to the gm dealer who, despite keeping the vehicle for another three days, still failed to find the problem. I decided to take the vehicle to an automotive electrical specialist but first searched the internet under "2003 buick electrical problems", and found that this was a fairly common problem that gm was aware of (a gm customer service representative had replied on one of the forums - edmunds.com? - that gm reads these forums). Having learned from the forums that the most probable cause was the ignition switch, I took it to an automotive electrical specialist who found a defective ignition switch and replaced it. (regret old part no longer available).

Ignition switch failure. Caused engine to die while driving. Unable to change gear out of drive. All warning lights flashing. Would not restart. Happened in a parking lot, no damage. Temp fix got it started, then same thing happened on freeway, coasted to shoulder, no damage. Towed to dealer, determined ignition switch problem and replaced. Okay since.
