Selected complaints filed with NHTSA by 2006 Pontiac G6 owners, lightly cleaned up (personal details are redacted by NHTSA).
1. Loss of power assisted steering making it hard to control car. But I turn off car and turn back on, it works. 2. Steering column knuckle or u-joints are making a loud clunking noise when turning steering wheel. 3. BCM or Body Control Mudule is either bad or needs cleaning because cruise control nor traction controls work. I checked fuses and they are ok.

Re: Pontiac 2006 -G6 gt elect. System, elect. Stability control, exterior lighting, service brakes, hydraulic, vehicle speed control --- this car was recalled for above problems in 2014. At that time I brought car to dealer to be fixed, although the car was not in need of repair because no problems had existed, dealer stated he fixed all recall problems at that time. Now two years later I am experiencing all the listed problems above. I took car to mechanic where he did replace parts but still experiencing problem. It must go back to dealer so problem can be alleviated. Brake lights do not go on when braking also when applying gas they sometimes go on. Cruise control is also not working. What's to say that this problem was never fixed in 2014 when the car was recalled due to the fact that I wasn't having any issues at that time. …
We are having the same issue with our 2006 G6. Our exterior light sometimes doesn't work, the cruise control sometimes doesn't work. We had to replace at our own expense the brake rotors due to inferior quality. We were having the vibration issue some mentioned. My wife could not get it out of park one day, we had it towed to the dealership. We got the same story about the recall about not being covered by the recall and having to get it diagnosed at our expense. Last year our brakes completely failed and we rear ended a minivan. Luckily no one was injured. But our insurance is going up. I cannot wait until our lease is up in feb 2010. We will trade this thing in and get a dependable foreign vehicle.
I was driving had the cruise control on at the time I could not get it to go off because there was a curve coming up before I knew it my car just would not stop and ended up crashing into the back of a pickup. I wasn't able to get the car to start braking until about 5 seconds before hitting the other vehicle. My airbag also didn't deploy. This happen 3 weeks ago now I am physical therapy because of the injuries sustained in accident. The recall came in the mail about a week after accident. Go figure prior to the accident I had my car at a shop getting oil change & they had mentioned there was a voltage issue but should be OK.
My vehicle was recently taken to the dealership for a recalled part (brake lamp malfunction) and my vehicle is still locking up. After fixing the recalled part I have purchased a battery, a caliber, starter, and two hubs. My car is still not working it will function for a couple of miles perfectly, and then it returns to the same problems. First it will not gear up the car will be on drive and it will take a couple of minutes to catch, then the car will lock up and not be able to move. So I will have to get a tow service because the ABS system will lock the car and I cannot push it to a safe area.
Problems with car started in June of 06, for abnormal noise, from underneath car, condensation was constant in headlights even after replaced. Car disc player would constantly malfunction and was replaced - steering was always seemed not just right. Car would accelerate for short spurts, trunk filled with water after a rain really feel the whole stability of the car needs to be seriously looked at. Husband received brain injury from what looked like he just plowed into a block wall for no reason. He held a clean driving record with a current cdl license.

Transmission feels as though it enter overdrive- brakes feel unresponsive and if responsive only slightly, and continues to accelerate with the transmission stuck. Car will eventually stop when emergency brake is pulled, and then the transmission will not shift out of drive. Steering wheel will become locked as well. After multiple attempts of turning the vehicle off and on, it will eventually unlock the transmission and will allow to be shifted into park. Vehicle is an automatic.
