The drivetrain: automatic transmission parking lock cable (or shift cable) malfunctioned. The vehicle is available for inspection upon request. I am able to put the car in 'park' and remove the key. However, when I attempt to start the vehicle, it won't start because the battery gets drained. I have to constantly get a jump off. My safety and the safety of others are at risk because I never know how much the battery has been drained, and the vehicle shuts off in trafffic. The problem has been confirmed by an independent service center. The vehicle has only been inspected by an independent service center. There have been no warning signs of the problem before shutting off or not starting. The vehicle was purchased in 2019, and the first occurrence was the same year. We knew something was draining the battery. We just did not know what. So we would not let the vehicle sit for more than a day without starting it, and we would always be prepared to charge the battery.

What owners say
I have had to get 3 new keys made for this car due to the security light coming on, sometimes it will not crank or start, so I have replaced the starter twice, have replaced relays and fuses, and the security light will come on while drive down the road and all gauges drop to zero, even the gas light says empty and every light on the dash comes on. But the car will still drive. But once you turn it off it will not start for a few hours! It’s impossible to find parts for Pontiac anymore so everything has to be ordered! This should’ve been recalled a long time ago!
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. Next problem I have is my airbag symbol pops up off and on while I'm driving and we'll stay on for a while and then go off and then it'll come back on about a week later and then it'll go off again and this happens when I'm driving on the highway down the street just randomly. Next is my power steering power steering when I start the vehicle and put my car into gear and attempt to turn my wheel to reverse or you know to get out of a parking position my power steering will be really hard really tight I try to turn it and I can't turn it very far because of the pressure behind it I will put my car back into gear turn off the car and turn my steering wheel as much as I can to the left as far as it'll go and then to the right as far as it'll go and then finally it will loosen up so where I can turn my vehicle.
Car wouldnt start thought it was alternator, then tried the battery and found out it was the brake switch. Brake lights stay on while car is driven and turn off when depressed
This is a 2006 pontiac g6 with the 3.5l lx9 v6 engine. At 90,000 miles I am having transmission problems (automatic). The transmission slips in 2nd and 3rd gear. The car reverses normally. All maintenance is done by myself or the dealer. I changed the transmission fluid with genuine gm parts and fluid. I noticed the fluid was slightly discolored and very tiny pieces of metal were in the pan. The transmission still slipped in 2nd and 3rd gear after changing the fluid. Obviously I want to avoid putting in a brand new transmission. I want to check the computer and and any electrical pieces that correspond with the transmission first before I decide. As a side note,I did bring the vehicle to gm for a diagnosis and apparently there was a code for a transmission position sensor. However I attempted to start the vehicle in drive on many occasions and the vehicle would not start which is what that sensor is suppose to do so I know it isn't the sensor.
The air bags like say service but no one see what's wrong, the fuel car will not crank after gas is put in. It ask to check gas cap even put new cap on and sti not working
On the night of decemeber 31, 2018, the family and I were getting ready to go out when we noticed the car wouldn't start and all the outside lights were staying on and dim. Prior to this night, my spouse noticed that the interior lights were staying on as well so he removed the fuse as a temporary fix so that I may go to work. I believe this may be due to the recalls that I recently found out about. Im uncertain of the exact cause of this issue but from what I've read about the recallsb I believe it may have something to do with either the ignition or the brake pedal shorting out the electrical system.
