After having brake assembly redone earlier in the month by Chevrolet dealership, I was still having problems with brakes/acceleration. I picked up vehicle from dealership on Monday and later that week (Thurs or Fri) I had problems not being able to accelerate after I had applied brakes when I was leaving a shopping center. On Sunday, I tried to put the car in reverse and it would not move. I tried pressing on brake pedal/accelerator, moving the gear shifter and nothing. Finally I was able to go in reverse with difficulty. I called the dealership the next day and took the vehicle in again. They kept it for a few days but could not replicate the problem I had experienced. I picked up the vehicle and guess what happened? I had the same problem again less than a week later.

I've now called GM and customer service contacted the dealership's manager. Not really sure what will come of this.
