7 Ignition Switch problem

Failure Date: 02/20/2014

About three weeks ago we had to replace a faulty ignition switch in our 2003 Buick Regal. A week prior to that, it began to experience "strange" problems: the "service engine soon" and "abs" lights came on intermittently; there were sometimes odd sounds during breaking and when using the turn signal. Then, one morning on my way to work, the car completely lost all power without any warning. Later that day it happened again. The first time it lost power, I had just put the turn signal on and slowed down to go around a car in order to get into my turning lane. If I had not already begun to turn the steering wheel, I would have hit the bumper of the car in the lane to my right. I was able to come to a complete stop and put the car in park. Fortunately--- especially since it was morning rush hour---I was able to restart the car and continue through the intersection. I proceeded on to work without further incident except that most of the dash lights had come on and remained on. When I pulled to end of the driveway as I left work, the car again stopped. I drove home and scheduled an appointment to have the car checked out the next day. The problem was a faulty ignition switch. Thankfully, there were no accidents as a result of the car losing power as I was driving that day, and everything seems to be back to normal since having the switch replaced. .

11 Ignition Switch problem

Failure Date: 03/02/2011

On mutiple but intermittant ocassions, 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).
