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.

I have owned this car since new. All service work was performed on time. 6T70 6 speed automatic transmission failed while taking my kids to school. No warning and slipped into neutral while driving. None of the drive gears would work. Lucky we were able to pull over without incident. We were traveling on a secondary road at 45 mph and could have been rear ended! took car to dealer and they wanted $800 to diagnose what was wrong with the transmission. Called GM customer relations, but they were not helpful since my car was out of warranty. Car had 5 year 100K warranty, but my car with low mileage was too old. This repair will cost me $3300 from a private shop. GM products are terrible. This 6T70 transmission is in GMC acadia, Buick enclave, Chevrolet traverse, Ford Explorer, and several other GM/Ford models. Should be recalled for bad reliability and safety!

At hutchinson mall, the car was being parked when the gearshift were placed in park the gearshift moved freely, we were not able to move the shifter to 'park' and remove the ignition key. The car was bought from conklin in hutchinson, plagued by problems. Conklin's "[xxx]" came and drove the car from the lot. We were charged over $200 to replace the shift cable. Looking on the internet it seems that it is a fault on the G6 that must be repaired free. Conklin replaced this without authorization from us and did not want to release the car without payment.

I have a 2008 Pontiac G6 that constantly has issues where the low beam bulbs will burn out. It kept getting worse as I was replacing them every 8-9 months. I just went to go take out the burned one the other day only to find that the whole socket the bulb is connected to was completely melted along with a nasty burn smell emitting from the back of the headlight assembly. Thankfully GM gave me an extended warranty due to constant problems with my car surrounding electrical issues so my car is being fixed my a local GM shop this coming weekend. This seems like a serious problem because other G6 owners have reported the same problem. There is something seriously wrong with these Pontiac G6 cars and GM needs to reimburse each of us for the full price we paid on these vehicles. Of you compare the amount of problems on this car vs all other cars on the market, this one by far has the most complaints on the national highway safety site. Of I had the money I would buy a new car that is not american. I hate my car so much. I hate GM for making me drive such an unsafe vehicle. There are two recalls still pending (according to the dealership) involving the brake light issue and shift cable issue. The dealership doesn't have the parts for either recall. This is such bs. Also, the dealership told me that they don't have to give me a loaner to address the recalls. From what I've read online this is illegal and they must provide one.

G6 6-cyl

  • 65,700 miles
Was driving and, car started to shake and kept missing gears. Rpms were up, exhaust was up but car would not catch and when I was going to park my car in the garage my car would not reverse at all, so I had to push it into the garage. Upon speaking with several Pontiac G6 owners, it is said that the 3,5 R wave plate was very weak, which made this transmission prone to failure in GM products. Updated wave plates were released for clutches in 6T70, the old design wave plates weren't stress relieved and could break with use. For it just being a $10 part this is outrageous that I would need to get a whole new transmission which costs 2-3K. Something needs to be done about this immediately before anyone gets hurt.

Was backing out of the parking spot, I stopped and tried to place it in drive when the shifter suddenly dropped straight down and the car started completely shut off and started rolling backward. Hitting the breaks and E brake to get the car to stop. My friend and his neighbor came and helped me push the car out of traffic. Friend who's a licensed mechanic looked at the car, checked the shifted and mentioned the link cable had snapped which is why the car was stuck in reverse. As of right now the car will not turn over since it's stuck in reverse. The shifter will not put the transmission back into park. Doing a little bit of research I found there is a recall on the model of car (14152) but GM has not placed my VIN as a concern.

From the time I bought this car, I have had an issue where when driving the car, as the transmission shifts from the different gears, the shift will be extra hard. It's like the car jerks as it shifts. I have taken this car to three different dealerships and had it placed on the computer at other different auto shops and no one can seem to find anything wrong with this car. It seems to really jerk when I have used the air conditioner or driven for extended periods. I am at my end with it..

The steering makes a constant popping noise when accelerating or turning the wheel. Radio buttons, especially on the steering wheel do not work. Transmission clutch pressure control solenoid malfunction. Transmission control module failure. Stuck in 2nd gear, reverse does not work, wont rev past 4000rpm. Started as a jerky acceleration, then warning lights came on the next day, limp mode engaged, transmission rebuild needed on a car with less than 60K miles!

Had recall part put on car 10/1/13 even though I did not have any problems with gear shifter. Ran an errand yesterday, stopped car, key would not come out, jiggled it, then it came out with difficulty. Came back, put key in, it would only go in half way. Then noticed shifter was not locking, it was loose from park to drive and steering wheel did not lock either. 4 weeks after shifter cable put on, I have a big problem, was stranded at store.

My vehicle was not able to shift out of park even thought the shifter would move. I brought it in to the dealer because it should have fallen under. Us NHTSA campaign id: 12V460000. They bill reads:"repair a: replaced transmission cable" cable end separated. Repair B: fractured shift cable end fitting locking tabs cause recall: Install transmission shift cable kit per 12106" I feel I have been lied to and taken advantage of. I don't see a way that the fractured transmission cable could be a result of anything else but the fractured cable end fitting locking tabs. I was forced to pay $300 to pay for something clearly related to the recall. Please help me fight back against the dealership.
