Selected complaints filed with NHTSA by 2007 Pontiac G6 owners, lightly cleaned up (personal details are redacted by NHTSA).
Tl* the contact owns a 2007 Pontiac G6. While the vehicle was parked with the engine turned off, it began to reverse out of the driveway and rolled into a lake. There were no warning indicators illuminated. A police report was filed. The vehicle was towed by the police department to the contact's home. Bradley Chevrolet of parker (2500 industrial park place, parker, az 85344, [phone]) was contacted to schedule a diagnostic appointment. The vehicle was not repaired. The manufacturer was made aware of the failure and informed the contact to bring the vehicle in to be repaired per two unknown recalls. The failure mileage was 136,000.
Replacement part (cable kit # 23238001) under recall 14152 has subsequently failed and as a result has not remedied the original safety concern which states, "if the transmission shift cable fractures while the vehicle is being driven, the transmission gear selection May not match the indicated gear and the vehicle May move in an unintended or unexpected direction, increasing the risk of a crash. Furthermore, when the driver goes to stop and park the vehicle, despite selecting the 'park' position, the transmission May not be in 'park.' if the vehicle is not in the "park" position there is a risk the vehicle will roll away as the driver and other occupants exit the vehicle or anytime thereafter. …
I'm on a busy city street and I went to put my vehicle from reverse into drive and I noticed that it wasn't going into gear and when I would accelerate on the gas to make my vehicle go it would just rev up like it wasn't a year and then I would you know take it back to reverse and then back to drive and it would still not go into gear finally after about two or three tries of this it finally got to go into drive and I made it to home the next morning when I went to leave I tried to crank my vehicle and it would not start so a friend of mine pop the hood and he noticed that the thing that puts my car into gear was not attached anymore and that is why my vehicle would not start and I had the problem that I had the night prior. …
There was recall on this car for transmission cable that caused May have caused the shifter to not properly stay in gear. My car did not have this issue, but the recall was fixed anyways. A year and half after recall was fixed the problem actually happened despite so called being "fixed". I called GM to report this and they stated they could only do something a year after the recall so I am 6 months out of this. Either their fix didn't work or their fixed caused the problem. Either way my car is now completely inoperable and I'm being forced to fix this out of pocket. I'm hoping you can possibly help get GM to actually fix this problem as it has been documented. I can get the copies of recall and it actually being fixed if necessary. How the problem happened: car was parked in park position at a parking lot. …
After coming to a complete stop - when I begin to accelerate the car does not want to move - then I have to let off the gas and try again it will slowly move and then jerk. It does a hardshift and will do this at random times- no matter if I have driven 0 or 10 or 100 miles . Sometimes it will hardshift when I first leave in the morning and sometimes it doesnt. Sometimes it hardshifts mid day - but it is always after a complete stop. If I use the tap shift then it does not do this. Others have been recalled for transmission problems exactly of this nature - but I do not see my specific VIN listed with a recall for this - I know 1 other person with this same car and they also have the same problem. Campaign# 14V224000 - recall # 14152 .my make, model and year are listed & I have owned my car since August 2013 and have never received anything regarding this recall. …
Tl* the contact owns a 2007 Pontiac G6. The contact stated that the exterior brake lights failed to illuminate when the brake pedal was depressed and the brake warning indicator remained illuminated. The contact also stated that the gear shifter would engage into neutral, park, or drive independently. The failures occurred numerous times. The vehicle was taken to bay ridge Chevrolet (1575 86th street, brooklyn, ny 11228, [phone]) where a diagnostic test located a failure code for the body control module, which needed to be replaced. The manufacturer was made aware of the failures and informed the contact that the vehicle was previously repaired per NHTSA campaign number: 14V252000 (service brakes, hydraulic, electrical system, exterior lighting, vehicle speed control, electronic stability control). The contact stated that the repair did not correct the failure. …
At red light, when light turned green, I stepped on gas and car acted as tho it was in neutral. It will not go except in reverse. I was able to drive it in the manual mode to get closer to home and same thing happened in manual mode in stopped traffic. I've since seen several other complaints on the Pontiac G6 owners forum, this is a problem with this year/make/model. I've gotten verbal estimates from a few transmission repair facilities and the cost to repair ranges from $2200-$3400. I cannot afford to fix this, and it's an issue that should be recalled as it has happened to so many other people. Just because no one has reportedly died it appears GM won't issue the recall. If this happens to someone on the highway in traffic it could very well cause injuries/fatalities. GM refuses to help when contacted. …
Tl* the contact owns a 2007 Pontiac G6. While driving 35 MPH, the vehicle stalled and was unable to be restarted. In addition, the brake warning light illuminated. The vehicle was towed to an independent mechanic. The contact was unsure about what parts needed to be replaced. The vehicle was repaired; however, the failure recurred. The vehicle was towed to the contact's residence. The vehicle was inspected by an independent mechanic. The mechanic diagnosed that the battery, rotors, and brake shoes needed to be replaced. The vehicle was repaired; however, the vehicle failed to start. The manufacturer was not notified of the failures. The VIN was included in NHTSA campaign numbers: 14V252000 (electrical system, electronic stability control, exterior lighting, service brakes; hydraulic, vehicle speed control) and 14V224000 (power train). The failure mileage was 150,000.
I had car in for recall of shift cable in 2014. On August 4 2016 I went to park car and there were no gears, car rolled into a fence before I could get it stopped. I had a mechanic look at car. He found what was wrong, which is part of shift cable that was recalled. I was told the shift cable was not replaced as the parts are original. I have pictures of original part on my car. I would like for the shift cable to be replaced properly but have gotten nowhere with any dealers, including the dealer who supposedly fixed part in 2014. I have been told that because the car was supposedly fixed that I am responsible to fix part on my own. This is an outrage! I will be in contact with a lawyer to sue the dealer and GM if car is not fixed. Thank you
