Driving on the fwy and suddenly all of my hazard lights start turning on at once. My car started to lose power and I had to pull off to the side, not even my emergency lights would work. This is the 2nd time this has happened, the last was a few months ago and had the alternator replaced. Could it be the alternator again? I think not, I have also had issues with my power windows. I am not a mechanic but, I believe there is an electrical problem that is causing a shortage.

Car is a 2008 Pontiac G6 gxp - the car is called cybil due to it's issues going on one day and not the next. I bought the car brand new with 128 miles on it. Latest activity is the engine light coming on and the radio screen scrolling low engine power and service ESC. If you turned the car off then back on a few minutes later it would seem to run right, engine light would stay on and 3 cycles later go off. Once off it would stall and lights and messages would go off again. This happened for 10 days in a row and on the 10th day the car stalled out completely on busy main road in the middle of rush hour. Managed to get the car started, moved off the road, and towed to a certified dealer. Dealer took 3 hours ($360) to run diagnostics on the car due to generic code of P0651 showing up. At time dealer moved the car into their facility all the warnings and lights had already reset and didn't present themselves. Diagnostics showed history codes for the brake peddle sensor (which has gone off before and was an issue before the recall notice and other $$ spent figuring out why tail lights went on and off at their own will) other was cam shaft sensor (which I see other complaints on) and throttle body sensor which I see no complaints on. There are service bulletins for the cam shaft sensor for the 2.2 and 2.4, but not the high feature L7Y - this is a safety issue and if GM knows the sensors are shifting and pushing into something this needs to be recalled to fix. I am lucky I wasn't on the highway when one of these stalling issues happened. Car is currently at dealer waiting on parts to arrive to the tune of $700 - no christmas thanks to GM. The brake peddle sensor should be included in the recall for the tail lights and it is not. Please open an investigation into the cam sensor issue and make them extend the brake light recall to include the peddle sensor!

At times im not able to go over 15 mph, or the engine will send a read out on the radio that states " engine reducing power", then the traction will state (on the radio) that the traction has turned off and the light comes on, also the powersteering notification appears on the radio and the car is not abel to be steered. The engine will no allow me to give the car gas to accelerate, and the engine will jerk, the rpms will go up and down by itself I called the Pontiac number for help they told me that there was not a recal open for my car and they they were not abel to do anything for me very rudely.

  • 135,000 miles
To sum it up started getting "engine power reduced" message from message center in vehicle. Shortly afterward the vehicle will begin flashing the traction control off light and shifting hard. Now the vehicle still shifts hard with the two above messages and is also stalling out when "engine power reduced" message appears. Many times after this the vehicle will not accelerate at all. Have to pull off the road, cut the vehicle completely off for a few minutes and then continue driving. Problem started intermittent and now happens every single time I drive the vehicle. I have had it stall out on the highway going over 50 mph, very dangerous was almost hit. Vehicle has been at the used lost service center three times, no luck on finding problem or repair. Car has been with my local GM certified dealership for 3 days and still no proper diagnosis problem or repair. Has sense received the two recall letters BCM/transmission but dealership is reluctant to repair because they said GM may not pay for time and parts. Worse car purchase I have every made.

I was driving down the road and all of a sudden my car jerked to the right and put me and my kids into the ditch. This has happened twice. The second time it did it in the same direction(right) but when I hit the ditch smoke was coming into the heat vents while my kids were in the car. Brought it to the dealership they told me that my power steering line was broke and also I had a major oil leak and that it was a fire hazard. They then told me the price of how much to fix it. It is no longer under warranty. I don't feel I should have to pay for something that seems to be factory mistake. I've also had an incident of my car shutting off while driving. The ignition turned off while driving only going around a corner. I only had three keys on my ring at this time. This car has been the most dangerous car I've ever owned. The brakes and oil light constantly come on. The air bag light has been on since for over several thousand miles. Also the tire psi sensors are always going bad. The hazard switch hasn't worked in over two years as well. But every time I brought the car in even with a warranty they never fixed any of these problems. What's it have to take for this company to make this car safe?? dos to make my to fix their mistakes seems like someone's going to have to get in a fatal accident for something to be done. Also my back left seatbelt locked up on my son squeezing him and it wouldn't release. The belt had to be cut to get him out.

Driving and suddenly engine light came on, across the radio it said engine power reduced and service traction. It would barely accelerate. It has done this twice in a week. Then after a while the engine light goes off and it will seem ok. At stops though, the car seems very shaky, feeling like it will stall, but hasn't yet!!!

Car accelerates without pushing on the gas, or when I am breaking car speeds up. A chime sounds in the car and I can't find anywhere in the manual about sounds other than the typical seatbelt to low fuel. Very scary!

I was driving about 40 mph then my vehicle started decelerating even as I pressed the gas pedal it would not go faster. It would slow down about 5mph and then accelerate maybe 3mph. I took the vehicle to get inspected but they could not find out what was wrong. It was a very scary experience and I guess my main question is has this happen too anyone else? it has only happened 1 time. I look forward to hearing back from you.
