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.

2003 chevrolet impala 3.4l is difficult to start, replaced many parts to try and fix: fuel filter, fuel pump, spark plugs and wires, oxygen sensors, fuel evap valve, and throttle control. Vehicle currently has 52,xxx miles. Security light flashes, was able to pull error code p1626: theft deterrent fuel enable signal not received. Keys are original to car, I have tried to re-learn keys to vehicle with no success. Numerous repairs are listed under this error code, including the replacement of the bcm, and this doesn't always fix the problem. This issue needs to be researched further.

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 mini explosion 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.

Vehicle is in parked and im about to start the vehicle it seems to slowly fail or backfires during multiple times of trying. While in motion on the streets driving at 10-35 MPH or in motion on hwy 40-65 MPH the vehicle will shut off or sometimes it would loss power even if my foot is on the gas petal. On hwy this could cause a series accident

The car will not start randomly for 10mins sometimes. Or sometimes it won't start for hours. The security light flashes and locks up. Gm needs too recall this, it leaves us stranded somewhere random when ever it locks up. Unable to start the car for a minimum of 10 minutes. When you are parked and try to start the car it will flash the security light. It does nothing but prevent the owner from using his vehicle, make gm permanently fix this on their dime. This has been happening since I've owned the car.

Found a gasoline leak at the quick connect fitting where the fuel line meets the fuel rail on top rear of engine. I believe its the fuel return line. The quick connect fitting is leaking fuel down onto engine and could drip onto hot exhaust manifold causing a fire. Car was stationary when I noticed the leak. I smelled gas first then traced the smell to the leaking quick connect fitting. This may be related to the recent gm recall of valve covers leaking oil causing the fires.
