I was driving and my car started to reduce speed, hesitate, and jerk when put my foot on the gas at a light to pull off or even with my foot on the gas pedal driving. My car couldn't pick up speed past 25 miles and sometime less. A message came up on my dash board stated flashing reduce engine speed. I was near auto zone when it happened so I asked to have a dianostic completed and it stated throttle/ pedal position sensor/ switch "e" circuit low input meaning code p2127.

The catalytic converter in my car needs replacement. I have been the only owner and have maintained it properly. The car has a little under 67,000 miles and occasionally loses power. It is a major safety issue as this happens sporadically. I can not with 100 percent certainty merge into traffic knowing that it will accelerate fast enough. I had a diagnostic run on the car and was told that the catalytic converter is the issue and needs replacement. I contacted the dealership in el paso, tx and they claim that some pontiac g6 models (based on VIN) have been recalled, but that mine is not one of them. I have looked up related cases and don't understand why my car's VIN is not included. I love my car and it has served me well, until now. I hope that someone, anyone with some authority is reading this. I hope that that person does some investigating and realizes that this issue is not isolated and should be an open recall. It is most definitely a safety issue. I do not feel that it is safe to continue to drive my vehicle, but am forced to as I cannot afford to have it fixed. The acceleration issue has happened on the freeway and on city streets. I have stopped using the freeway for safety reasons. Please look into this issue.

Gear shifter moves but car rolls as its in neutral no matter what when I went to put my car in park it still rolled forward, when I put it in reverse it still rolled foward. Its as if the gear shifter isn't putting it into the correct gear. Now I have turned my car off and it won't restart because it doesn't think its in park? What could this be?

"takata recall" in my pontiac g6 after I hit 100000 miles I started having all kinds of problems. My ABS light keep coming on and off. My theft-deterrent alarms comes on and stay on while I drive. Then it goes off stay off for a day maybe then come back on. The traction control warning light comes on and stays on then goes off and come back on. The car pulls forward, which is scary. I drive slow because I want to make sure I can stop if I have to. I took my car to the shop. Put it on the diagnostic machine the codes that were coming up contradicts what the car is actually doing. The mechanic said I may need a computer but I may he really did not have a definitely answer on what is going on with my car. There is no recall for my (VIN) but I believe their should be.
