“In feb of 2003 my Pontiac Grand Prix caught fire after I parked for the evening. Since then, insurance refused coverage for suspicious in nature. In 2003 Pontiac claimed no responsibility, GM's 100,000 mile warranty was a refused. After complaining again in 2006 Pontiac called again to say they were not at fault and had no responsibility. I asked them for corresponding VIN numbers and was refused. I have located over 15 additional Grand Prix engine fires where GM / Pontiac is claiming no responsibilities. Once ? Twice ? 10 + ? …”

During routine maintenance, the mechanic discovered that there was only a piece of plastic used to close the etr valve at the fuel injector rail. This is where the fuel line connects with the motor. The failure causes the gasket to overheat, and could lead to an engine fire due to fuel leaking into the overheated motor. The contact is afraid to drive the vehicle.
