NHTSA — Power Train Problems

2006 Pontiac G6 (Page 3 of 3) 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.

I was making a left hand turn at about 20 mph and my power steering cut out. I almost crashed my car into a pole, but was able to tug at the steering wheel and avoid the pole. I had to turn my vehicle completely off and then back on to rest the power steering. This has occurred countless times while driving my car. I have had this happen to me at least 20 to 30 times.

We bought this car brand new, and troubles started immediately. First thing was when you would turn the steering wheel it would make a popping noise, well returned it a few months after we bought it they said it was because of a cap, that use to be metal but are now plastic wears out, nothing dangerous but annoying. Well that was replaced 3 times before some kind of a rod was replaced. Then it always smelled of anti freeze. And would lose it, but they couldn't find any leak. Well after having it in having 2 radiators put in it, it still did lose fluid. Until recently I had an accident where a lady left her car in the middle of the highway and ran off and left it in the middle lanes coming off of a bridge a man slammed on his brakes and I hit the side of his bumper, and caused damage to the front of my car and I got a new front end and a new radiator again. Still leaked fluid. My husband after getting the car back from the repair shop found the leak and bought a part and fixed it himself. Pretty good after 3 radiators and all the techs working on it over the 6 yrs, he had to fix it. It has been in the shop right after I got it because when you would take off, it would act like it skipped a gear. But if I shifted w/the standard shift it wouldn't do it. They said there was no shavings in the transmission tray and all was fine. Took it back again for the same thing, they still said nothing was wrong with the transmission. But to this day about once or twice a week it will still skip when accelerating. I have had the motor on the convertible replaced right after I got it. The stereo was also replaced. The passenger side chair arm release, that allows you to let the seat up for someone to get in the back came off, they put another one on and no adhesive it stripped out again. Refused to fix it. I have all paperwork from all the repairs it has had, will list in anotherpost.

The electrical power steering assist assembly and module locked up nearly cause an accident, I can't drive now until it's been corrected by Pontiac. I just bought the car and just made my first payment. [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

As many owners of this vehicle are experiencing..trouble getting the vehicle in gear from park, have to step on the brakes to the floor. Brake lights work in the reverse direction and 3rd brake light stays on when foot is not on the please..this is a matter of safety and may cause injury or VIN number was not listed on the GM recall. My VIN number was about 1,000 cars after the recall.I am going to a GM dealer and I have been told a new brake pedal comes with the brake sensor..I do not want to throw a ton of money not knowing the exact problem.

The contact owns a 2006 Pontiac G6. The contact stated that the vehicle failed to start. In addition, the transmission failed to shift into park. Also, the contact was concerned that the vehicle would roll away as a result of the failure, possibly causing a crash. The vehicle was not taken to the dealer. The manufacturer was made aware of the failure but did not offer any assistance since the vehicle was not included in any recalls. The vehicle was not repaired. The failure mileage was 70,000 and the current mileage was 90,000.

My Pontiac G6 was running perfectly fine with no lights or warning signs and always well maintained to date. I pulled up to a red light and the light turned green and my car would not move in drive it would only rev. I was able to put it in trip tronic shift and make it to a transmission shop. It was slipping also in trip tronic in first and second. The repair places said that it was internal transmission problems. My only option was to get a whole new transmission put in well a rebuilt one. This should not be happening to a 6 year old car that was well maintained with no warning signs. I talked to several people at GM headquarters and they just don't care and act like its my fault there bankrupt Pontiac company produced unworthy reliable cars. And dixie GM where I took it to get fixed wants to rip me off and charged me double of what other transmission places in the area quoted me. I took it there because I thought they would be honest and give upfront answer and not jack me around because im a young women. Its not as if I went to mcdonalds and asked for a steak. Come on GM I thought you guys were better than this!!

I have had a thumping in the car when turning the steering wheel and was told that the steering gear needs to be replaced and there could be other defective parts once they get into it. At present I cannot afford to fix the problem and am saving up to get the $800 repair started. I feel this is a recall issue that GM needs to be forced to recall the G6's for this problem because a faulty steering system is a safety issue. I do not feel safe driving my car but it is the only means of transportation I have, so at this time I have no choice. Also, I have had other major problems with this car every year since I bought 3 years ago. The first year was a sensor in the transmission, the second was the catalytic converter, and now this year the thermostat and sensor and this steering problem. This car is a lemon and needs to be recalled!

2006 Pontiac G6 V6 stalling while in drive and park. There were no events leading up to this and has occurred six times. While driving at low speeds or in park, the car will suddenly turn off and the check engine light will illuminate. The brake and steering will also lock up. Upon turning the car off and placing it in park it will restart, I have placed the car in the shop two times to have this fixed. Last time (May 18) was to tape engine wires and clean the fuel injector, which they said would fix it. This repair cost me $500. Since then the problem has increased, happening three times in the past three days. I have contacted Pontiac numerous times but they are unwilling to help. Both my GM dealer and I have used a code reader to see if the car is throwing out a code when it stalls but nothing can be found. My car has quickly become a liability to myself and those around me, as the last time I stalled I almost drifted into a busy intersection. Something needs to be done to fix this problem, which is apparently quite widespread in 2006 G6S.

I have a 2006 Pontiac G6 that has started to make a clunking sound when I turn and makes this weird humming sound when I apply the brakes (at times), when I press the gas (at times), when I turn (at times), and sometimes when I am just driving forward, which makes it very hard to pinpoint exactly where the problem is coming from. I have read numerous other complaints about this "clunking" sound when turning and feel this issue should be addressed and resolved asap. J from

My problems started with this car before I even got home with my new purchase. I had 2 children in the car and the tire blew off the rim damaging the fender notes from the invoice state that "parts and labor to be billed to 67D 67F, cannot warr tire that has been mounted wrong on 1st repair" then on 6/26/06 paint was refinished due to clear coat peeling on the hood. On 11/06/06 radio does not play cd's and radio was replaced. 3K mile service with motor silk. Also airbag light was staying on and they said they found a wire to SDM loose and repaired wire. Also right rear tire was leaking air. 4/20/2007 engine was knocking loud when first started in morning at that time they replaced the lifters. The engine was replaced shortly after that and again had problems with the air bag light staying, dealership again said it was a sensor but this is only a few of many issues I've been having with this car. Please contact me and we will go through each one or you can contact the dealership where this lemon was purchased and request the records (I have a copy too)....
