general problems of the 2003 Chevrolet Impala

Fuel line leaking gas under engine.

I just recently bought this vehicle 03/11/20 and it ran great till yesterday when the intake manifold exploded and caught fire to the engine from the fuel lines melted this happened when I was getting a jump. It says there are no recalls pending it is the 3. 8l and it looked original all the parts did can you please help me out.

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.

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.

Yes my engine oil is leaking and it making my car hot and I think my oil pan is full of oil every time I put oil in it it run straight out and I can't drive my car more than 20 minutes straight or it will just cut complete off and my brakes is going out they want stop on time.

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.

Tl-the contact owns a 2003 Chevrolet Impala. The contact stated that while driving at any speed, the vehicle would start to shake with a knocking noise then it stalled without warning. In addition the vehicle transmission leak flued and also failed to start. The vehicle was taken to an independent mechanic where it was diagnosed that the engine is bad and needed to be replaced. The manufacturer was not notified of the failure. The approximate failure mileage was 149,000. Aw.
