Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

NHTSA — Fuel System, Gasoline Problems Seal Of Avoid Like The Plague Notes: The 2005 Pontiac G6 has major problems with two areas fairly critical to the act of driving... steering & safety.

The 2005 G6 has a major defect trend with electronic power-assisted steering failure. The power steering cuts out while driving, making it extremely difficult to steer. G6 owners typically report spending $600 - $1,200+ to fix the problem, replacing either the entire steering column or the power assist motor.

In March 2010, GM recalled 1.3 million vehicles for this exact problem "...after receiving 1,100 complaints of power steering failures." However the 2005 G6 wasn't included in that recall.

In July 2010, GM issued a "Special Coverage Adjustment" — TSB #10183 — covering "certain" (not all) 2005, 2006 & 2008 Pontiac G6's for power steering problems, up to 10 years/100k miles.

As of early 2013 the NHTSA had 300+ steering complaints on file for the 2005 G6, with 12 crashes & 4 injuries. The NHTSA closed their initial investigation in 2007, having determined that losing your power steering going over 15-20 mph isn't a big deal & that most crashes occurred at slow speeds, so not a safety risk. Ridiculous? Yep, we think so too.

The 2005 G6 also has an expensive problem with "popping" or "clunking" noises when turning, & that issue extends to newer model years as well.

Factor in the 2005 Pontiac G6's poor side impact protection & you end up with a vehicle you should steer clear of.

For several months now my 2005 G6 hesitates and jerks significantly when I push down on the gas pedal from a stopped position. From 0-10 mph the car takes a significant amount of time to gain enough power to move forward for the level of depression applied to the gas pedal. I've taken the car to several mechanics, including a GM dealer. Not a single mechanic including GM can figure out what the issue is. I called GM to place a complaint, and I stupidly thought with all the GM issues and law suits going on now possibly their assistance as 1) this is a safety issue. 2) my car only has a little over 63K in mileage. I explained to GM that I cannot at this time safely accelerate onto a busy highway, go through an intersection, or accelerate quickly should I god forbid have to. I requested them to investigate further as the dealer could not find issue. They told me to spend more money and take it to another GM dealer to try and diagnose. Told them that's stupid,4 mechanics including a dealer could not locate issue. Like my steering issue (before the recent recall) GM basically told me to drop dead. The GM representative told me if no mechanic can find it, maybe its time for a new car.

I had parked my car in my driveway, when I noticed a gas smell coming from the back end of my car. When my father in law came out he saw that there was gas leaking onto my exhaust. After doing research online I have come across a recall for the full pump seal. I contacted GM and are claiming to not have any information on this recall. I as well called airtrex productions and they will only take it after market. Why was I not warned when I bought this car less than a year ago. GM needs to buy these cars off of us! because it is their fault we have such issues.

The contact owns a 2005 Pontiac G6. The contact stated that there was a gasoline odor present inside the garage where the vehicle was parked. The vehicle was taken to an independent mechanic, who diagnosed that the odor was caused by a crack in the high pressure fuel line and that the fuel pump needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 87,000.

Friday shortly after returning home from work and parking my car in the garage, I walked outside to retrieve something from the garage and upon opening the garage door, I nearly fell over from the gasoline fumes that I encountered. My entire garage was filled with the vapors of gasoline. I was very concerned but did not see any leaks around my car. I did not dare attempt to start the vehicle for fear of fire. I did not drive my car all weekend. Monday morning I took the car to a mechanic and he discovered the fuel assembly unit had a leak near the fuel arm mechanism leading to the engine. This required replacing the entire fuel assembly unit. The plastic piece should show no signs of wear and tear since it is encased within the fuel assembly unit. This is clearly a flawed design and it should be recalled. It is an extremely dangerous situation to have a fuel leak and had I been parked at my office in the underground parking structure, a lighted match or cigarette would have been disastrous. This defective fuel assembly must be recalled as it poses a great safety risk to persons and property. My check engine light never came on nor did any other warning message alert me to the potential danger this defect caused.

Deteriorated/cracked elbow on fuel module assembly caused fuel to pool on top of the fuel tank. Severe fuel vapor smell noticeable in enclosed garage, which could have been ignited by gas water heater. Fuel also could have ignited while driving, if it had come in contact with the muffler. Research indicates this is a common problem with the G6.

My grandma owns this car, when I visited this week there was a very strong odor of gas in her garage. She told me it has been present for more than 6 months. I immediately had her open the garage door and made an appt with a mechanic. It was the cracked elbow on the fuel pump that had been continuously leaking gas onto the top of the gas tank. The fuel pump was replaced, which cost more than $700. After speaking with the mechanic and a simple computer search I realized that GM is well aware of the problem. It is outrageous that GM allowed this to go unannounced. She runs a kiln in her garage at heats over 1800. she had essentially a bowl of fuel sitting on her gas tank for over 6mo. While she drove and while it was closed in her garage. Thank god she's safe, because it was no thanks to GM.

The vehicle has a very strong odor of gasoline around the perimeter of it that is very noticeable when near the car. Vehicle just recently was inspected for emissions and passed the California smog check. The smog check technician advised that the vehicle needed to be inspected further. I found online that other Pontiac G6 owners have experienced the same symptoms. I have contacted GM Pontiac customer service and they have not indicated one way or the other if they will pay for repair as the vehicle is out of warranty. The dealership gilroy Cadillac Chevrolet has ordered part and is going to repair and indicated cost of >$1,100 they said that a plastic elbow fitting on outside of fuel tank is cracked and spraying gasoline on top of fuel tank and that the entire fuel pump module needs to be replaced. Fuel pump is functioning and car runs fine, with the exception that it is a fire hazard!

I have been smelling gas from vehicle but did not notice leak. Did notice lower miles per gallon. Took vehicle in for brakes and mechanic informed me I was lucky the car hadn't caught on fire. Took pictures of gas pool on tank. The fuel pump elbow is cracked and the entire unit needs to be replaced.
