I was driving my 2004 grand am and I was sitting in stop and go traffic on an hwy and it was hot outside that day and when I let my feet off the brake pedal my car start to accelerate by its self very fast and I immediately press my break to the floor and my anti-lock breaks kicked in and the car continued skid and accelerate fast and I had put my cars transmission into neutral and the motor continued to rev even after my transmission was in neral. I ended up skidding up a side walk to avoid a serious crash or being killed in a bad crash. I believe it was a defect in the vehicle speed control accelerator pedal.

Was driving normally down road on way to work. Approached intersection and depressed clutch to down shift and apply brake to stop vehicle. However with clutch depressed, the vehicle began to rev up on its own without the accelerator pedal depressed, until it reached the red line. After pumping accelerator about five or six times vehicle stopped revving up. However several miles down the road the vehicle began to rev up again when clutch was depressed to shift gears. This is an ongoing issue, vehicle has been seen by gm dealerships and gm rep but they claim issue cannot be replicated. Multiple parts have been replaced but issue continues. Will a major accident or death be required for this issue to be addressed? I realize that this is probably not sticking out as a major issue because of low numbers of reports of this same problem, but I would imagine that since this is probably isolated to models with manual transmission which is a very small minority of vehicles. If thought about in the fact that their are few vehicles configured with a manual transmission, the fact of the number of reports of this issue makes it more significant since it would equal a higher percentage of vehicles when compared to the total number of vehicles configured with a manual transmission.

The cruise control on the bottom of my steering wheel has come undone. The case housing around it popped off, and now it won't secure back onto it. The three control buttons used for cruise control now slide out, and the "on" button won't stay pressed. The car works fine, short of the frustrations of not being able to use cruise control, and having that major eye sore inside the vehicle.
