Motor mounts were broken what's resulted in the vehicle lunging me forward when coming to a stop. The check engine light for the hybrid battery also came on. The result is the car shaking and shutting off more than once when attempting to accelerate from a stopped position. Once was in a very busy intersection. It shut off when coming out of a bank parking lot and turning on to a busy street.

When driving around and at a stop light the engine will go into auto stop. When applying pressure to gas pedal the vehicle will hesitate and then lurch forward. Vehicle will also get a high idle between 1500 RPM and 2200 RPM and fluctuate between those rpms. Also when idling below 1,000 rpms the engine will rev up and down as if pressure is being applied to the gas pedal but there is no pressure being applied at all. Been having this issue for quite sometime and I figured it was just some bad fuel but it has been consistent. Also have no lights illuminated on the dash, no check engine lights or anything. I haven't taken to dealer yet because I am waiting on the supplies for the air bag recall so they can work on the vehicle while replacing the air bag.

Started car, put in gear, depressed brake pedal, and it went nearly to the floor. No vacuum assist and the car was very hard to stop even at a rolling speed. The following lights illuminated: check engine light, stabilitrack indicator light, ABS warning light, brake system warning light. The following displayed on odometer screen: service stabilitrack, service traction control, service brakes soon. Vehicle has been at dealership for 2 weeks, with repeated calls to gm engineers, who first recommended replacing the master cylinder, which cost $1000 and did not fix the problem. Since then, the engineers apparently say it is the hybrid brake valve modulator that has failed, which will cost additional $2300; however, the dealer cannot get the part and not sure if this will fix it. This hybrid braking system is defective and dangerous!! I cannot imagine what would have happened had I been driving at full speed. In reading forums, I am not the only one with this issue. I hope the federal safety agency reads this with all the recalls and coverups that gm has had to deal with in the past few months. A recall should be issued.

I had a check engine light on a 2008 chevy tahoe hybrid. I was on the way to the dealer when the engine moved to almost wide open throttle. I tried to stop the vehicle with the brakes but the power of the vehicle was too much. I moved into the center turn lane to not hit anyone and put the vehicle in neutral. The throttle was still almost wot. I was less than a half mile from the dealer when this occured. The vehicle lurched into the dealership parking lot with the smell of burning brakes. I asked the technician to come outside. He noticed the floor mat was wedged inbetween the floor and the brake pedal. This had caused the check engine light to keep coming on. There are no pegs or clips to keep the floor mat from sliding under the pedal. Very dangerous to be driving a huge vehicle with electric and v8 power and it won't stop.
