NHTSA — Fuel/Propulsion System Problems

2009 Pontiac G6 (Page 2 of 2)

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.

G6 4-cyl

  • 3,000 miles


I purchased a 2009 Pontiac G6 in Dec 2009. When the vehicle was taken into the dealership for its first oil change (@3000 miles), a fuel odor was detected coming from the rear wheel area. This smell was mentioned to the dealership and the owner was told by the service writer that it was a 'shop spill' and not from the car. On other occasions a fuel odor was detected by the owner, but they were dismissed as flukes. Recently, (06/13) a very strong fuel odor began coming from the rear wheel area of the car. The hotter weather seemed to make the problem more noticeable. Research was done on various blogs and forums, and the owner determined that the problem was most likely a cracked fuel line or fuel return line on the top of the fuel tank and that the dealers charge $800 or more for the replacement of the fuel pump assembly. The problem has been a known issue for the G6 since the 2006 model and as yet, General Motors has not done the "right thing" and issued a recall. If my vehicle was much older or had a lot of miles on it, I might feel better about this problem occurring, but the vehicle only has 33,000 miles on it, and is only 3 1/2 years old. I hope that no one dies from this design/manufacturing defect before General Motors takes appropriate action and recalls these vehicles. I know that it would be very costly, but much less expensive than the potential lawsuits they will have to settle if someone dies or is injured or property is destroyed due to fires. I know that I would stand up in court with this message and the internet postings that show this is major problem and testify that "GM knew about this problem and took no action". hopefully, somehow G6 owners can get together and force GM to take the corrective action that they should and reimburse the owners that have already made the repairs.
