NHTSA — Fuel/Propulsion System Problems

2006 Pontiac G6 (Page 1 of 4) Seal Of Avoid Like The Plague Notes: The 2006 Pontiac G6 has major problems with two areas fairly critical to the act of driving... steering & safety.

The 2006 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 2006 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 this power steering issue, up to 10 years/100k miles. However a large number of 2006 G6 owners have reported they were not covered by this campaign, based on VIN#.

As of late 2013 the NHTSA had well over 700 steering complaints on file for the 2006 G6, with 21 crashes & 12 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 2006 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 2006 Pontiac G6's poor side impact protection & you end up with a vehicle you should steer clear of.

There is a gasoline smell coming from my car at all times. I did research and there are several complaints regarding this problem for the same exact car. This is definitely a safety problem and needs to be fixed. I believe it's a crack in the fuel tank or hose. Ive noticed since a couple of weeks ago.

Owner of a 2006 Pontiac G6. Strong smell of gas coming from the car. It takes a 2nd attempt to start the car as well. I've seen there are many others over the years with the exact same experience but no recall even though there was a recall on other years for the same issue but not the 2006. Since we're long past any warranty, I had hopes of a recall but since there isn't, I'm looking at over $1000 for parts and labor to fix the fuel pump line now right before the holidays. My teenage daughter has been driving this car and it's scary to think what could have happened.

The contact owns a 2006 Pontiac G6. The contact noticed a fuel leak underneath the rear center end of the vehicle. When attempting to accelerate, the vehicle would "kick" before accelerating forward and stall when initially attempting to start the vehicle. The contact would have to turn the ignition key a few times before the vehicle would successfully start. The contact took the vehicle to a certified mechanic who diagnosed that fuel was leaking into the exhaust due to a faulty fuel pump and fracture on the seal to the fuel tank. The mechanic diagnosed that the seal and/or the fuel pump needed to be replaced. The vehicle was not repaired. The dealer was not contacted. The manufacturer was not made aware of the failure. The approximate failure mileage was 134,000.

Just recently I had my Pontiac, 2006, G-6 repaired at the Chevy dealer. They couldn't find any fuel leak until the were going to drop the fuel tank. There they found the fuel leak. They removed the fuel pump and replaced a new fuel pump. I had called GM Pontiac to check on the Pontiac, 2006 G-6 recall. They said there are no Pontiac G-6 recalls. I told them that there are a lot of complaints for the 2006 Pontiac stating that the fuel pump leaks. According to airtec they did a recall on their fuel pumps model no. E3591M. This pump looks exactly like the pump they took out. They stated the fuel pump seal will leak gas.

I have been smelling gas for some time now. Mainly when I park the car. The smell lingers for a great while. I haven't seen a physical leak on the ground but my husband looked under the rear a noticed gasoline on around the fuel system. I have looked for months now on the internet and I am not the only one with this issue. Now looking at the NHTSA website, this issue has been filed about 50 times and no one seems to be doing anything about it. I personally cannot afford to take my car to a dealer since they charge an arm and a leg. Plus I have looked up some of the parts involved and it is just out of my budget. I need my car to get work to make money to pay bills and it amazes me that the manufacture, whom should have gotten word by now about this issue since the oldest complaint filed looks like from 2012, has gone nothing in regards to this and forcing owners to pay out of pocket to get this issue repaired. Like many others who have filed a complaint about this, I say it is a safety hazard that needs to get investigated and recalled. Not eveyone can afford to repair. I just hope that it is not too late and lives are lost before action is taken.

Fuel pump has developed a hairline crack in elbow bend that causes gas to leak on to my gas tank and run down on to my exhaust which my mechanic said it is likely to cause a fire while I am driving since it is a high pressure line and hitting my exhaust. Car has a gas odor at all times even when not running. While parked in your garage my house fills with the smell of gasoline to the extent my family is having headaches and nausea. Friends at work can smell it in the parking lot several cars away from my car. Upon looking online I see this is a common problem with the

The is a significant fuel smell that is coming from the passenger side of the vehicle. The smell of fuel is also very prominent on the inside of the car. I am very concerned for the safety of my family as this issue is a safety hazard. Newer Pontiac G6 models have been recalled for this issue. The 2006 should be repaired through a recall. It is obvious the company is aware of the issue with the fuel tanks.

I have a 06 G6 2.4L 4cyl and lately it has been giving off a strong fuel smell. I smell it when the car is stationary as well as when the car is in motion. I checked for leaks under the hood and car and cannot find any. When I attempt to crank the car it doesn't start until my second attempt. I had a mechanic look at my car and he could not figure out what the issue was. I am becoming more and more worried with this issue. I have a small child and his car seat is located in the passenger rear. I am very concerned for his safety as well as mine. I am afraid that one day my car may burst into flames while we're on the highway, at a red light, at the mall, etc. Putting not only our lives at risk, but also the lives of others nearby. So I took the car to auto zone and they hooked it up to their scanner for free. They gave me this code - P0454 fuel tank pressure (ftp) sensor intermittent.
