NHTSA — Electrical System Problems

2005 Pontiac G6 (Page 3 of 4)

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.

I noticed that when trying to park my vehicle the steering wheel locks up. It is difficult to steer and appears that there is no power steering. The problem does not correct itself until you are going more than 20 mph. This continues to be an ongoing problem.

I have been having several problems with the electrical system in my 2005 Pontiac G6. When driving to work my power steering failed, I was able to pull over thank god. My dash lights blink on and off as well as fuses keep blowing. I understand there has been a recall for the G5 and G8 for the power steering and I also know of many others having this same problem with this model. Please check into this problem before someone wrecks.

The contact owns a 2005 Pontiac G6. The contact stated that while driving 60 mph, the wheel jerked violently. The failure would recur sporadically and in addition, the steering wheel would also seize without warning. Also, the interior lights would operate intermittently. The dealer diagnosed that there was a sensor failure and that the alternator needed to be replaced. The vehicle was repaired but the failure recurred. The manufacturer was notified but denied any assistance with repairs to the failure. The failure mileage was 23,000 and the current mileage was 132,557.

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.

2005 Pontiac G6 - water pours from the interior lights splashing the inside of the car and driver which is as unexpected as a child running in front of a vehicle. The sudden downpour may cause the driver to loose control of the vehicle when they look up to see where the water is coming from.. nobody was injured in my incident however, the water is coming from the drain tubes from the top of the car which have a tendancy to become disconnected. I am told this is not considered a safety hazard but a driver does not expect to be suddenly soaked by water when driving a car and can cause the driver to become reckless which may cause damage or injury to a vehicle or a person if it has not already. This is a common problem and needs to seriously considered as a safety hazard. Other than the safety hazard that it is, it also causes the interior of the car to be completely destroyed from mold and/or mildew needing complete replacement. The dealers are very much aware of the problem but yet I have taken my car in twice and because it wasn't leaking at the time, the could not see a problem. Mind you the back floorboard and seat were completely soaked from 8 gallons of water which had been sucked out of the car prior to driving it to the dealership.

I bought the car in April of 2008. In July of 2008 I was experiencing problems with the brake lights working opposite, cruise control stopped working as well as instrument panel. I had a new body control module put in my car and it was fine up until November of 2010 when I started having problems with the instrument panel again. In December of 2010 my brake lights started working opposite again as well as flashing while I am driving. I have been harassed by other motorists who I have gotten mad because of this problem. It is a serious safety issue as other motorists cannot tell if im braking. I have called GM this week and they have told me that the work I had done for the same problem is no longer under warranty. Surprising. I have done some homework and looked up the 2005 Pontiac G6 problems and it shows only a small majority of these cars have been recalled for this problem. Mine was not on this list. Why? I have also found thousands of other owners with the same problem.

The contact owns a 2005 Pontiac G6. The vehicle would not start and it was towed to an independent mechanic where the contact stated that there must be a problem with the computer. The vehicle was taken to another independent mechanic who stated that she needed a new battery. The battery was replaced but the failure recurred and was taken back to the independent mechanic who advised the contact to have an authorized dealer diagnose the failure. The wiring to the fuse pump was replaced by an authorized dealer. Approximately 4 days later the failure recurred. The vehicle taken back to the dealer where the contact was informed that they could not find anything wrong with the vehicle and they were unable to duplicate the failure. The VIN was not available. The failure and current mileages were 86,000.

In early may while in san antonio, Texas approximately 2 hours from my home town my battery died. The reason my battery died is because I have been experiencing difficulties starting my car. A technical bulletin that was brought to my attention for the LX9 engine seems like it describes the problem to a tee. It is on "intermittent extended crank time on hot engine restart, starter may not disengage after engine start". the engine turns but I will usually have to turn the key back and restart it at least a second time for it to actually run. I have taken the vehicle twice now to the dealership and have been told each time that they are unable to reproduce the problem so they cant fix it. Each time calls for another diagnostic test and fee. On May 5th all the extra juice to turn on the car cause my battery to drain completely so I was stranded for hours in a town where I know no one. This is a recurring problem that just cant seem to be fixed.

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

I was diving my 2005 Pontiac G6 when I was turning into a busy intersection my power steering locked up and the light on the dash lit up, almost causing a head on collision by cars doing 50 mph. I was just sitting in the intersection because I could not control my car after that happened almost getting hit by another 2 cars. I turned my car off and back on and the power steering worked again. Took it to the dealership they replaced the power steering motor because it was under warranty. The steering wheel column needed to be replaced but wasn't under warrant so they did not replace it. They said it works for now but it could go out anytime im driving, which can cause an accident. I couldn't believe what happened thought it was a fluke just my luck, only to see so many people having the say problem in the same year, in the same car with the same mileage. The power steering went out with no warning. These cars need to be recalled asap somebody will get hurt or even killed by this. I was only doing around 20mph and almost got hit three times head on and from the back imagine if I was on the expressway or even turning down a side street and loosing the steering and running up a curb endangering innocent bystanders. Since these are newer cars there are so many of these cars out there that haven't experienced this yet but will. Not only people driving these cars are in danger at anytime but other people are to. I almost got hit head on by a Ford truck his life wasin danger just as much as mine. How these cars are not recalled yet blows my mind"????" so many people lives are in danger im driving a car that they said that there is a possibility that it could happen again. Are they just going to wait until people get killed by this if not already or come up with a solution before more people lives are at risk. These cars need to be looked at and recalled asap. I heard something about an extended warranty but they don't make extended lives. Recall asap recall asap.

Owner of a Pontiac 2005 G6. I have had it in to the dealership in the past to work on a knocking noise in the steering column. During hotter months the knocking noise is more active. I have had it in at least twice to the dealer to deal with this. The last time it was serviced they claimed it was the I shaft. It was lubed and repositioned. There was also noise from steering gear. The gear was replaced and set toe in. As of this last Friday, June 12th, I was driving home from out of town and the "power steering" message showed up on my console. I figured there must be something wrong with the fluid and had my son get the booklet out of the glove box. The power steering was drastically tightening up. This startled me since it involved navigating traffic and getting it off the road especially since I also had my son with me. We pulled off the road and could not locate a specific area for putting in power steering fluid. The car was taken to the Pontiac dealership. We were told this was a computer issue with the car - there is no hydraulics - and that the steering column must be replaced for $750. I, too, am filing my complaint with NHTSA today for the safety of families when in transportation. This has been a huge inconvenience to us especially when the car has been in for service for the same similar reasons that others are filing their complaint! when I read that others as well lost power to others, this highly concerns me! I am also not satisfied that without a recall, only a replacement part my be used to fix the problem until an actual recall is ordered and the actual problem is fixed. This means I will still have to worry about driving my vehicle and be cautious of the problem happening again. This is not a suitable alternative for the consumers who have purchased these vehicles!

Well it all started for my stupid purchase of a ?!@#$% car, I have had numerous problems with this car costing me tons of money. 6 times I have had to replace my rotors and my brake pads because of a jolting shaking feeling with this car and I was told that the rotors are warped and that they need to be replaced. They never changed the rotors all they did was mill them down, 3 times they milled them down and the problem kept coming back until my warranty ran out they said your on your own. Sometimes I try to start my car and it will shake and put and die out and then it I will try it again and it will start, but I have had my car not start back up 2 times and had to get it towed and fixed and all they said was it was a dead battery but this happened 2 times with in a year and it still happens now. I started my car and started to drive and my steering wheel would violently jolt it self to the left and the right and it actually hurt my wrist from this and then the car died out and had to pay for towing and problem was a dead battery is what they said. Passenger door some how filled up with water and caused all my electrical to go haywire in my car and showing door ajar over and over again and it would go off causing my interior lights to not go off, my flood lights wouldn't work, cd player and radio only work when they want to work now, and some of the lights in the car go on and off when they want. Power arm in my car has been replaced 2 times already costing me a fortune and it needs to be replaced again, wonder if that has to do with the shotty rotors and brake problems. After revealing this to GM all I have heard back from them was to take it in a get a diagnostic test which I will have to pay for and then they might do something about it. Don"T buy any Pontiac cars, the warranty only means if there is a problem they will do nothing to fix it and when warranty is up your on your own. Still haven't had anything resolved with this vehicle.

The contact owns a 2005 Pontiac G6. The contact noticed that the steering wheel was extremely difficult to turn. She also experienced roughness while driving, accompanied by a loud, indescribable noise. Lastly, it was difficult to remove the key from the ignition. She took the vehicle to the dealer and had the drive-shaft replaced along with a sensor in the instrument cluster. Immediately after the repair, the failure resurfaced. Speed was not a factor. The failure mileage was 31,100 and current mileage was 49,000.

I own a 2005 Pontiac G6 which I purchased from a dealer after it had been leased for 1 year. The vehicle had 12000 miles on it when purchase. Numerous problems have occurred with this vehicle after purchase. Starting with a noise, clunk in the steering. This has been in the repair shop for upwards to 7-8 times, each time new repairs done on different parts. This problem has never been resolved. Now at 64500 miles the noise is still there after repairs only 4000 miles ago. Starting in October of 2007 I began having problems with the brake lights and cruise control. Brake lights working only sporadically as well as the cruise control. There has been documented repairs on the is of 7-8 times as well. This problem also has never been resolved. On September 17, 2008 my car was involved in a rear-end automobile accident in most part and no doubt due to faulty brake light system. Many other problems have occurred with this vehicle as well including poor sunvisor manufacturing, leaky map lights in overhead console, rapid wear of brake pads and rotors, rapid tire wear, starting drags when starting, occasionally the car will not shift out of park when the car is running and brake pedal is applied.

I am the owner of a 2005 Pontiac G6 four door sedan. For the past two months the engine check light has come on along with a warning on the audio display showing "power steering". these incidents were infrequent and no particular reason was found for the warning. Up until last week I attributed the problem to a faulty sensor. Last week I started my car and the check engine light came on, the "power steering was displayed in the audio system, and I had no power steering to for the vehicle. I turned the vehicle off then back on and the problem was gone. On Saturday 08/30/2008 while driving on a straight road the warning lights came on again and I lost power steering in the car again. I pulled to the side of the road, turned the car off then back on and the problem was gone. On 09/03/2008 I started my car and the warning lights again came on and I again had no power steering. I again turned the car off then back on and the problem was gone. I then drove to red hoagland Pontiac in bradenton, fl for repairs where I was told two modules needed to be replaced and it would cost me $1,095. I read a recent blog that stated there had been about 19 similar complaints for this vehicle and that a recall would probably be coming soon from your Agency. The cost of the repair is outrageous but more importantly if there is a serious problem with the power steering this vehicle should be recalled.

G6 6-cyl

  • Automatic transmission
  • 36,000 miles
2005 Pontiac G6 GT: Within the first year of ownership, we had the vehicle into the dealership twice for a leaking panoramic roof. The second time it leaked, the dash shorted out. Then at about 36,000 miles we started hearing popping noises when steering at low speeds. At around 42,000 miles the popping noises got significantly worse. It was at this point, we decided to take the vehicle back to the dealership for service. The man at the service desk seemed to know right away what was wrong with the vehicle without even diagnosing it. He told us that he had seen this problem in a lot of G6S. I asked him if it was something to worry about and he said no. He told me it would cost $550 to fix it and that the cost would be on me as I was out of warranty on mileage. After I returned home I decided to do some surfing on the internet to see if anyone else was experiencing G6 steering issues. I found page after page of people experiencing similar steering issues. In fact, I noticed that the NHTSA was even investigating GM for G6 power steering failure affecting some 176K vehicles. Frankly, this scared me to death! so much so, that the very next day I went down to the local Honda dealership and traded in the G6 for a 2008 Honda Accord ex-L (5-star rating). I took it in the shorts on the trade-in, but I cannot tell you how happy I am to get rid of this nightmare! parting question: Since when is "power steering failure" not worthy of a recall. Shame on GM!
