When my alternator failed it caused an over current through the ABS relay causing damage to the wiring harness melting the bracket and breaking one of the clips the other clip broke when the GMC dealer was doing their inspection. I'm working with an extended warranty that doesn't believe the damage was caused by the alternator and not the dealer.

I drove from South san francisco, ca, to san francisco, ca (8 miles). The car was operating normally. As I approached the 6th St. Exit, I applied the brakes to my car. There was no response; the brakes felt 'locked' under my foot, and the brake pedal would not depress to the floor. The car was moving rapidly forward at freeway speed, and I had no way to slow it down. I then saw the display had a warning something to the effect of 'service brakes soon.' I was travelling at approximately 65 miles per hour and very afraid of a collision due to not having any means to stop. The 6th St. Exit had a high ramp, and there was still no response from the brake pedal. Fortunately, the car slowed enough going up the ramp to avoid a collision, and I coasted to the first intersection where I pulled over to assess the situation. The brake pedal would not move at all, and I turned off the car. After about a minute, I turned the car on again, and the brake pedal was working again. There was no warning on the display. I safely pulled out into traffic and continued for about half a mile before parking to meet my husband. Approximately one hour later, I started up the car again, and it appeared to work; there was still no warning signal at all about servicing brakes. I began to make my way back down the street when, two blocks into the drive, the warning signal came on and I was unable to apply the brakes. I was fortunate to be slowly moving through an intersection, and I was able to safely pull over into a parking space at the side of the road. I called my husband, who came in his car to help me. We called for a tow truck and my husband saw to it that the car was taken to serramonte Chevrolet in daly city where it was repaired (cost: $3727.91, miles: 34,136). The Chevy Spark ev does not have a handbrake to manually stop the car, putting the driver at extreme disadvantage.

This vechicle has been having problems with the braking system and speed. When I brake it's something coming up under my feet and then the traction light comes on, :slippery when it's wet light" on the panel. Now, I had taken it to bob bell twice and they keep saying they fixed it, but my car has been in the same conditioned. I want something done before I lose my life.
