G6 6-cyl

  • 55,000 miles
Two weeks ago, it became increasingly more difficult to remove my key from the ignition after putting my key into park. At times, it may take up to 5 minutes to remove my key. Within a week, I noticed that it was becoming more difficult to shift from park to reverse. Last Sunday, (June 1, 2014) I was at the grocery store, shifted into reverse, then drive. When I put my foot on the gas, it was as if it was in neutral. I had to drive the car home in the manual setting. My husband then test drove the car and noticed the same things. He added that when in drive, it was as if the car was in neutral and it would actually move backwards if on a slanted road or street. My husband drove my car into bradshaw motors, wade hampton, greer, SC the next day, Monday, June 2, 2014. They said we need a brand new transmission. With only 50,000 miles on my car, (which I bought new) I became very upset and began to investigate recalls. I found a recall #14V224000 on the www.pontiacproblems, com/recalls/G6/2007 website. I called the 1-800 number and have been getting the run around on the phone sense.

G6 6-cyl

  • 64,245 miles
Pontiac 2007 G6 GT started to show signs of issues shifting automatic trans into park around 50 thousand miles. The issue became apparent when I put my shifter into park and pulled my keys out and went to get out of the vehicle and it started rolling backwards and almost hit two people and another vehicle in a parking lot. The vehicle will be shifted into park but isn't actually in park. I was informed by the dealer that supposedly my shifter cable has started to "fall apart" my vehicle is now at 66 540 and it has become to the point where I am forced to have this issue fixed because the shifter cable is completely destroyed almost. I am under the belief that this is not only a huge safety concern if someone doesn't realize the car isn't in park but it is ridiculous that I am asked to pay 400 dollars for a repair that should be covered under the powertrain warranty. I have requested for GM to pay for this repair and they have denied my request because they are already trying to repair the fact that my airbag's don't work that I filled in a separate complaint on here. Huge safety issue that almost cost me my car and could have cost two people their lives or at least their mobility. GM refuses to accept that there is a defect in the shifter cable and clip on the 2007 model of the G6 and not just the 2009 that they claim. This exact same issue is present in the 2009 G6 and has been recalled but not the 2007. I am requesting that this be investigated further because GM should be paying for these repairs... a part starts to fail 3 thousand miles after I receive the car as "certified" from GM.

G6 6-cyl

  • 6,500 miles


Situation: The G6 was on cruise control at about 50 mph, the road was in Vermont hills/mountains, the weather was raining -- from light to an increasing intensity. The wipers were turned on to the low pulse setting, and as the rain intensity increased the pulse frequency was increased one step at a time. When the pulse was at its fastest, and the G6 was proceeding up an incline and the cruise logic was in the process of deciding to shift gears, the windshield wipers stopped enough to obscure all vision. This condition repeated itself until I changed the pulse setting to constant. Then, again, but this time in West lafayette traveling from the main road North out of town up route 443 between route 43 and 52 on cruise at 35 mph in a rain with the wipers on fast pulse the wipers stopped and vision was obscured. Sooo, the hill/incline does not have to be 'mountainous' or very long in duration. The dealer in vt suggested I should just put it on constant pulse to avoid the issue -- duh. The dealer in Michigan attempted to replicate the condition but city traffic, etc. Prohibited the 'experiment'. the GM customer relations contacts simply kept telling me that the condition 'did not exist' because it could not be replicated -- which was the same as calling me a liar. Duh. Yet the GM cr would not allow me to discuss the issue with anyone involved with the vehicle design or build -- because "it could not be duplicated" yet I duplicated the vt occurrence in Illinois in different terrain. Since the 'hill' in West lafayette is very typical of hills in most of the states in the usa it is likely that anyone driving in the conditions noted would experience the same result. Yet, no one in GM will sit and discuss this at a functional level. When the wiper stops and no one can see out the front windshield, whether traveling at 50 or 35 mph the condition is very critical and a serious accident can occur. I have been trying to discuss this frequently since it occurred.

  • 32,200 miles
Automobile purchased as new. Rotors not vented properly and were replaced with brake pads at 32,200 miles. Insisted that dealer/Pontiac corporate handle under warranty. At 32,900 miles car stopped at light and did not advance when accelerator was depressed. The transmission required full replacement because the sprag "blew up" and was covered under power train warranty. Will never lease or buy Pontiac again.

I purchased a used 2007 Pontiac G6 for my daughter in November 2008. Since that time the car has shut off unexpectedly or not started on occasion. Recently she has been experiencing difficulty in turning the steering wheel and the power steering fluid light is on. Upon research we were informed that the G6 does not have a power steering pump and has an electrical engine. Upon further research I have found that many owners of the Pontiac G6 have complained of this problem to no avail. My daughter's safety is a concern and I want to know what GM has offered to its consumers to solve this issue.

G6 4-cyl

  • Automatic transmission
  • 10,000 miles
The contact owns a 2007 Pontiac G6. While driving less than 70 mph, the contact noticed that the transmission slipped when switching lanes. The vehicle would not accelerate when the accelerator pedal was depressed. The dealer made the necessary repairs. On a separate occasion, the steering wheel made a loud clunking noise when it was turned. The dealer repaired the steering column. While traveling less than 70 mph on another occasion, the engine made extremely loud noises, especially while idling. The failure mileage was unknown and current mileage is less than 10,000. Updated 03-06-09 the consumer also when the headlights were on, the turn signals would activate and the headlights would go off. Updated 03/12/09.

G6 6-cyl

  • Automatic transmission
  • 1,200 miles
We own a 2007 Pontiac G6 gtp. My wife backs out of the driveway in the morning stops completely, puts the car in drive, however the car sometimes will not go forward for 5 to 15 seconds. We have taken it to our dealership many times for this problem. They ended up replacing the transmission. At the time there were less than 2,000 miles on this car. The problem still continues, it is still doing the same thing.they just finished putting in 2 new front axel shafts. The car now has 4,700 miles on it. My wife is very afraid of this car as she almost got hit because it would not move forward. She refuses to take this brand new car out of town, because she has no idea what might happen next.
