NHTSA — Fuel/Propulsion System Problems

CarComplaints.com Seal Of Avoid Like The Plague

CarComplaints.com 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.

My car is smelling like gas I have a leak and im thinking its the fuel pump leaking. My son is a certified mechanic and he looked at my car. He is the one who also said that is probably the fuel pump.there were recalls on 2006 and up in years on the fuel pump. I have one a year 2005. I think they need to check on the 2005S for this problem.

When I drive my car, a strong odor of gass fills up my car. It is so strong that it gives me a killer headache. I have a gas leak coming from the back of the car. The shop I take my car to have told me that it is more than likely a fuel pump leakage. They have told me that they have had to fix many, many fuel pump leakages on Pontiac G6S. Also, my tail lights have stopped working for some reason. They both stopped working at the same time. The gas leakage seems to leak durring and after I drive it. The tail lights... I had just gotten off of work when I got into my car and the police officer I work with told me they were not working. That same night I got home and locked my car. I went to get something out of it and they were working fine. After a few days I was pulled over again because they had stopped working again. They currently do not work. The officer also brought up the strong smell of gas she present.I got pulled over on an innercity road.

I first noticed the smell of gasoline when the car was parked. If it was parked on a slight incline, there was a puddle of gas on the driveway. Because I saw online that many others were having a similar problem, I checked to see if there was a recall...but there wasn't. I finally had the fuel pump replaced because I was afraid of a fire. Will I be reimbursed if there is finally a recall done on this very dangerous issue?

Took my car to the GMC. Dealer to get recalls fixed. They also noticed strong gas odor. Inspection stated I had a gas leak at the top of my tank and it was dangerous but no recall on this so almost 300$labor +parts... I called GMC and they said my car had too many miles. And 10 years old. I don't feel like I should have to pay for an issue that is clearly from the manufacturer. Any help or advice please! my car could burst into flames.

G6 6-cyl

  • 182,000 miles
On September 2014, I purchased a 2005 Pontiac G6 with about 182,000 miles for the purposes of driving me to work. I was not aware or made aware of a strong fuel smell emitting from outside and inside the car at low or high speeds. I drove the car to my local mechanic for inspection a few days later. I was later advised that a fuel pump connector was possibly cracked and leaking gasoline above the gas tank. My mechanic also advised me not to drive my car any further since it posed a fire danger. In addition, GM recalled the 2007-2009 Pontiac G6 vehicles for the same issue but not for the 2005-6 Pontiac G6 cars. My car currently has two recalls which my local GM dealership will fix in the upcoming week. Many customers have complained about the same issue and no recall has been made to address this problem. Why hasn't this issue been recalled with the faulty fuel pumps" why should I have to pay out of pocket for a manufacture defect"

I smelled a very strong odor of gas as I walked up to my car. The check gas cap display came on. I replaced the gas cap and warning is still displayed. The smell of gas has continued to worsen and seems to be coming from the gas tank. It doesn't matter if the car is running or not. I have researched and found many owners of the same year and make car are having the same problem however, nobody has found the exact cause. Suggestions have been to check evaporative solenoid, gaskets, tubing to and from tank. I've done all and the odor continues to worsen.

We started smelling gas in the passenger compartment a few weeks before 8-27-12 and could not locate the gas leak. Then on Sunday 8-26-12 my daughter drove up and the smell of gas was overwhelming. I looked under the car and saw gas running through the vents in the metal shield covering the gas tank. The car was parked until it could be inspected by a mechanic. I did a online search for a gas leak for the 2005 G6 and could only find reference to this same problem on the 2007 and later models. I called two GM dealers and they showed no recalls on the 2005 model for gas leaks and could not give me an estimate for total repairs unless I agreed to spend approx. $300 dollars for an inspection. I called my mechanic and they removed the exhaust system and gas tank from our 2005 G6. I made a video of the gas setting around the fuel pump and on top of the gas tank. They cleaned up the tank, then did a pressure test which showed a crack in the elbow which is made onto the fuel pump assembly. The old fuel pump assembly is still a working part except for the crack which I believe is defective workmanship. I made a video of the new fuel pump assembly after its installation and I see no difference in the way the part is made. I also have the old working part with a video of where the cracked elbow is located. On 8-27-12 I spent $505.06 for the fuel pump assembly, $44.82 in sales tax and $225 in labor. I am concerned that the new part will do exactly what the old part did and I will be stuck with a leak again. I find no comfort in knowing my daughter could be riding around in a car that could literally be a bomb. If someone checked the facts, I think this particular fuel pump assembly has been used for quite some time and has always had problems but were out of the warranty period. How convenient! I always thought that buying GM meant made in America. Guess not!
