NHTSA — Power Train Problems

2005 Pontiac G6 (Page 2 of 2)

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.

While driving down the road at approx 30 mph I started to accelerate and the transmission seemed to down shift very hard and caused the engine to rev extremely high and when it went to shift up it shifted so hard it seemed the transmission was going to fall out. This was also followed by the check engine light coming on. Since this incident this happens on a regular basis and but not every time I drive it. Nor is the check engine light always on. I also have trouble sometimes putting the car in park and trying to remove my key from ignition. I have to move the shifter back and forth to get the car into park to remove my key. On most occasions when I am at a complete stop and go to accelerate the engine will rev really high and I have to take my foot off the gas to allow the car to shift.

My son was traveling home and discovered that the steering wheel became hard to control. Due to recent shoulder surgery in December, it was very difficult for him to control the steering wheel. In an effort to gain control, he placed pressure on the shoulder and safely got the car off of the road. Due to the pressure on the shoulder, he was taken to the orthopedic center to have his shoulder examined for additional injury. After reviewing over 132 complaints online and the recalls that were made for the 2005 Pontiac G5 but not the 2005 Pontiac G6. My wife and I are very distraught that the G6 was not placed on the recall list and that our son was so close to losing his life. We purchased the pre-owned vehicle in May 2011. Since there has been so many complaints and close encounter with bodily injuries and/or death, we have also contacted the GM manufacture to determine why the Pontiac G6 was not placed on the recall list. We only want this problem repaired to ensure that our son is driving a safe vehicle and therefore are requesting an investigation into this matter.

I was driving approx 30 mph and when I went into a curve the power steering quit working and I almost ran into the ditch and hit a mail box. Luckily, I missed both of them but pulled a muscle in my shoulder trying to keep the car on the road. I pulled off to the side of the road and my 3 point turn turned into a 8 point turn. The power steering light was on the screen flashing. This can be very dangerous and deadly. This needs to be a recall before someone dies and the company is sued, considering the fact that I'm seeing this reported quite often.

We own a 05 Pontiac G6. This vehicle has a chronic issue with the brake pedal sensor. When the sensor is having issues, it is extremely hard to get the car to go from park to drive. More importantly though is then the sensor causes the brake light to work in reverse. When you apply the brakes, the lights go off, when the pedal is not depressed, the light stays on. We have had several sensors replaced and now have been told the "fix" is the electrical lubricant. This electrical lubricant is only good for a few months. Obviously, it is a half[xxx] "fix". we have been to several "former" Pontiac dealers only to have been told we are "out of luck". this is an extremely dangerous situation. While driving at night, if you depress your brakes and no lights come on it could lead to a rear-end collision.thankfully this last time my husband was warned of this event by a gal who was driving behind him. My husband has been pulled over by the police because they thought he was drinking. He was told that a characteristic of a drunk driver is that they "ride their brakes". GM needs to get this corrected!! it is not safe. We purchased this vehicle for my husband who drives 50 miles round trip to work everyday. This is an accident waiting to happen. We are seriously contemplating trading in the vehicle for another one because of this and other issues with the G6. It has been a lemon since we got it between this brake issue, a "clunking" noise when turning (which we were told is "nothing" from our former Pontiac dealers) and the panoramic sunroof leaking and noise issues, which as well we were told nothing can be done about. (we had standing water in the vehicle w/ the leaks) this brake issue needs to be looked at!!!! we will not buy another GM vehicle because of this crappy service and lack of care in getting this vehicle recalled. What is it going to take"?" I have seen other complaints addressing this same thing. I would implore NHTSA to see what can be done about this.

(1.) merging onto the highway at approx. 15mph. Picking up speed. All of a sudden and for the (2.) first time since having the car the power steering light came on the console along with a "dinging". the steering wheel immediately locked up extremely tight. Even as an extremely healthy well built person I could not turn the steering wheel and almost went over the embankment. I hit brakes luckily with no one behind me or infront of me. I managed to bring the car to a complete stop. (3.)turned car off. Restarted. Power steering light off. Steering wheel unlocked itself. In the processes of contacting dealership and/or manufacturer for service.

In October of 2009 I bought a Pontiac G6 2005 after a month of a owning the vehicle my check engine light started turning on and on the display area it would read power steering this was at the beginning of November 2009 since then the power steering had continued to fail on a regular basis, in order to fix the problem I would put my hazards on and pull over turn the car off and turn it on again, this would allow me to regain my power steering. This problem went on for months it is now Aug 2010 and I have gone and had my power steering column replaced at a GM dealer near me... within the past 10 months the power steering failed on a very regular basis I had to pull over multiple times( 4 5 6 ) in one trip and turn the car off and on again to regain power steering, the power steering would give out at not only under speeds of 20 km but at speeds of 60 km or lower.... I am a single mother who drives around with my 3 year old child everyday I do feel that is an issue in many Pontiac G6 made in 2005 that needs to be addressed for my safety and that of my sons..

I have a 2005 Pontiac G6 GM recall # 80317 - the recall does not include my VIN #. my vehicle has every symptom and issue that the recall calls out for but GM/Pontiac will not honor the recall because it does not include my VIN #. is there anyways that my VIN can be included in the recall? I am a safety hazard as my brake lights dont work, my cruise control doesnt work and when I try to shift the car out of park, I have to apply a lot of force to the brake pedal. All of these are issues that are called out in the recall. Thanks aaron slavey
