Vechicle shuts off when at a stop light/sign after taking it 3 times to multiple mechanics including the dealer- king pontiac, MD, no one is able to identify and fix the problem, I am told that they can't identify duplicate the problem and identify the code to fix the car.
When using turn signals car dies, all the dash lights flash and click. If I pull over and put the car in park it restarts and drives fine until I try the turn signal again then the same thing happens. I also had to disconnect the emergency brake sensor or else the same thing happens. Flashing, clicking and car dies. Now, whenever car is in gear, constant dinging and it will drive fine but I cannot use the turn signals.
2003 Buick Century 4dr - I have had for almost six years and this happened only one time. Thank god. I left walmart on side street, slowed for stop sign ahead, the engine went completely dead, lights and instruments out, I came to sudden stop. Could not restart car, doorlocks had automatically clicked, locking us inside, we could not release or open doors. We were locked inside our car. Luckily I wore cellphone. About ten minutes later, out of the blue, the power came back on all at once, lights came on. I was able to restart engine and unlock the doors. It was a rather scary situation for a few moments. I thought, "what if there had been a fire in the engine compartment?".
