NHTSA — Fuel/Propulsion System Problems

2006 Pontiac G6 (Page 2 of 3)

CarComplaints.com Seal Of Avoid Like The Plague

CarComplaints.com 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.

I've noticed a strong gasoline smell coming from the rear of my car. I went to get an oil change and the technician showed me where gas is leaking from somewhere on the driver side of the actual tank. The gas is running down the side of the tank causing it to drip from the fuel tank cover. I have to get an assessment to find out where the problem actually lies and how much time and money it'll cost me to repair it. From the looks of the other posts, I'm not the only G6 owner with this issue. The issue is endangering the lives of drivers and their families/passengers. I would like for GM to issue a recall immediately to repair these issues.

June of 2008, the service airbag light kept coming on. I took it back to the dealership where I bought the car from and they said it was the passenger side seat sensor that needed to be replace and since it was still under warranty at the time I didn't have to pay for it. After getting it fixed it hasn't come back on until about two years ago and it is now no longer under warranty and I was told if I don't get it fixed then when it comes back on then the airbags won't deploy. February of 2011, the check engine light came on and I had to replace all four of my O2 sensors and then the brain in order for the check engine light to go off. But every winter the check engine light comes back on when the temperature is 35degrees or lower and then I am unable to remote start my car. I have had it checked and code that keeps coming up is that I have bad O2 sensors but when they are checked they are still good. Both of these are a real pain. Can you please check to see if there are any other complaints. Thank you.

The Pontiac G6 2006 fuel pump is faulty and there's alot of complaint on the internet about this part.the strange thing about this issue is GM knows about this issue but for some very strange reason recall the vehicles from 2007-2010 and left off the 2006 model which seem to suffer most from this fuel pump defect from the plastic made part on their pump.the dealership after charging me $134 just to diagnose the problem which they knew from before wanted an additional $1200 to replace their own defective pump which they recalled on the 2007 model and many other vehicle....its a major rip off and a damn shame ! this issue is a major issue, gas is leaking on the exhaust and its a fire hazard.there are over 300 complaint on this on the internet from the 2006 G6 model and I am only one of them...GM should do right and recall these vehicles for the proper repairs...like they did for the 2007...

My car has been smelling like a gas station my husband has looked into this and it seems to be leaking near the fill neck. After looking at forums it seems that this is a common problem and you have a possible recall on the G5 I now cannot drive my car it is so bad and it is just sitting in my driveway I guess we will be waiting on yet another recall on my car.

Vehicle was taken in for oil change and put on lift. Technician said, there was a strong odor of fuel(gasoline) coming from the rear of the vehicle. The tech showed me the location of a wet spot and we both touched the area and our fingers smelled like fuel. They want to charge me $850.27 for parts and labor. My choices are clear, get the thing fixed, or burn in an explosion. I strongly believe that many other motorist with this make and model have the same problem.

Hey my car was leaking gas and after driving a ticking time bomb for two weeks actually learned what the issue was the gas cable connected to the fuel pump had a leak from wear and tear and gas was coming out. If someone threw anything lit behind my car it would have blown up this fuel pump issue should be a recall I was charged a hefty repair bill as well im really starting to regret this Pontiac G6 GT coupe the car itself should be recalled if it isnt the steering its something else.

Driving 65-70 mph on highway while raining. Lost quite a bit of power and started to stahl. Message flashed across message screen stating "reduced engine power". had to pull of to emergency shoulder lane. Left car on the side of highway for a little over 24 hours. Came back next day and my car started right up with no problems. This happened 3 more times with the same outcome. Around 4 weeks ago, while driving on the highway, no rain this time, I heard the chime and message screen flashed "power steering." My power steering was immediately lost, I managed to merge over to left lane and into the emergency lane. While merging, the screen chimed once again but now displaying "reduced engine power". my car stalled and completely shut off. Once stopped, I pulled out key from ignition. Replaced key in efforts to restart my vehicle. The ignition would not turn over. My vehicle was completely dead at this point. Around 10 hours later, returned to vehicle on highway shoulder, car started right up on the first turn of key. This exact incident happened 4 days later with same outcome. Recently last week and this week, while starting my car, once I place my vehicle in reverse. My message screen will chime and display "power steering" and loose all steering capabilities. I can fix this myself by turning off the engine, removing key, wait about 30 seconds and try again resulting in normal use.

After returning from a short trip, I noticed the smell of gasoline around the car. After checking under neath the car. Gasoline seepage was observed on the side of the fuel tank. (not filler neck) after dropping the car off at the dealership were it was purchased, the faulty part was determined to be a fuel pump nipple was leaking.the fuel pump assembly was replaced for a mere $998.75. The fuel pump is located at the top of the tank and is totally protected and should not have failed. The car has only 52,000 miles on it.

Fuel pump went out, these parts are supposed to last a lot longer than this. Fuel was leaking from the top right side of the gas tank. Took it to a mechanic and found it was a cheap plastic part on the fuel pump. Unfortunately the plastic part is part of the fuel pump assembly and a totally new fuel pump needed to be replaced. Mechanic reported that this is common with the G6 models.
