2003 Pontiac Grand Prix Owner Comments

Grand Prix

  • miles


The contact owns a 2003 Pontiac Grand Prix. 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. There had been no failure to date.

There is a web site www.edmunds.com that talks of a oil leak from the supercharger, I think a closer look at the fuel connection is the place the fires are coming from.

Once " twice ? 10 + " I read that NHTSA had begun another investigation in Feb 07 and would like more information on this. I would be happy to forward copies of any of my materials including 2 separate fire investigations that claim my fire started by the drivers head lamp under the air filter assembly, including receipts that show where GM serviced my fuel assembly 2 weeks prior to the fire...
