2009 Pontiac G6 fuel system NHTSA complaints: Fuel System, Gasoline

NHTSA — Fuel System, Gasoline Problems

CarComplaints.com Notes: The 2009 is starting to have the same problems as previous model years, including the headlights blowing out due to bad connectors.

The wiring harness connections aren't a big deal to replace, as long as your dealer or mechanic doesn't charge you an arm & a leg to "diagnose" the problem.

Was on thruway going 65mph car shut off for the third incident in approximate of a year from other 2 incidents. This time was or could of been killed due to this problem due to rate of speed and where I was driving onto an on ramp where I broke down.car dealer replaced engine control module #12612397. I no longer feel safe driving this car because I know this will happen again. I think this vehicle should be added to the recalls going on with GM because the same thing is happening to my car.

I have already made a complaint about the Pontiac now I am making another complaint. The Pontiac G 2009 is already starting to do the gas tank expanding. There is something that needs to be done about this.
