Vehicle shuts off when moving, turning or stopped at a traffic light. By switching to neutral, the engine may start after 1 or more tries. So far the failures have been on city streets and highways. But not interstates. The failures are many but unpredictable.

The incident happened this morning as I was leaving for work. My car was parked in our driveway and had not been driven in 2 days. I got in the vehicle and put the key in the ignition and as soon as I turned it to start there was a loud bang that sounded like a gunshot which I thought was a backfire. The entire plastic intake manifold gasket had exploded into pieces and white smoke began to rise from under the hood. When I opened the hood and the smoke cleared I began to assess the issue, I noticed the manifold gasket cover had been blown completely off and the manifold itself was in pieces. I've done some research and this seems to be a common but uncommon thing among early 2000's GM vehicles.

Coolant system has been an ongoing problem with the vehicle. After refilling coolant and oil, it was discovered that oil and coolant were dripping underneath the car. According to a GM representative, there are service bulletins out for this year make and model, but I've been told my VIN is not one of them. It has all the same symptoms described in other bulletins. I'm not sure how/why this VIN isn't included when the same symptoms exist.

Under the hood fire and unintended key rotation. Maybe 5 days after I took my vehicle into tc Chevy (in ashland Oregon) to have the 2 recalls repaired on it. I tried to start my car and it caught on fire down by the front bumper and the flames made it to the back side of the motor and ignited the fuel lines causing a MINIexplosion under the hood, mean while I'm sitting in the driver's seat. I jumped out of the car nearly having the life scared out of me, I popped the hood and grabbed my house garden house and started to try and put the fire out and minimize the damage to my vehicle while I waited for the fire department to reach my house. The fire department showed up and was able to get the fire put out almost torching one of the firefighters head when the fuel pump kicked on without the keys in the ignition and started shooting gasoline reigniting the fire. I'm lucky the fire didn't burn down my house and my neighbor's house that day seeing how the fire caught the bush next door on fire and there was flames 14 ft in the air. See Chevy and GM have been trying to act like the fire and the damage to the vehicle is my own fault and none of their own even though the technician says none of the repairs were actually done. I've been trying to get an investigation done and they're trying to push my claim aside and sweep it under the rug. My vehicle was parked in my driveway at my home right next to a bush not my neighbor's house is right up against. Please look into this so that it doesn't get swept under the rug. Please help me. I also have the firefighters report.

When I am driving down any road, stopped and turning the ABS system engages causing grinding noise. Loss of power and periodically brakes lock up and gas pedal locks. When pulling off from a stop I can not accelerate & RPM goes almost red line, car starts to jerk and and transmission doesn't shift. I have to let off gas pedal and allow to shift. It has stalled numorus times when pulling into traffic and almost caused me to be hit. The service traction control/ABS warning light dings and stays lit. I manually turn off ABS but problem still occurs. Also the wiring thru out the car has failed to my rearview mirror, domelights and radio panel. My gas mileage has significantly decreased. The problem started around the beginning of the year and has progressively gotten worse to the point I and scared to drive my car.
