NHTSA — Electrical System Problems

2009 Pontiac G6 (Page 4 of 6)

CarComplaints.com Notes: The 2009 is starting to have the same problems as previous model years, including the headlights blowing out due to bad connectors.

The wiring harness connections aren't a big deal to replace, as long as your dealer or mechanic doesn't charge you an arm & a leg to "diagnose" the problem.

The car has had significant electrical problems since its purchase. To summarize: I had an ignition fuse repaired in 2009 when the car turned off suddenly while I was driving. Replaced a faulty headlight socket that was melted to the inside housing, have replaced an excessive number of light bulbs in the car, and have also had the power door locks fail. Most recently, remote ignition was not working, but was later fixed after a major repair last month to the power steering. I was driving the car when my power steering failed. Had it towed to a local GM dealership, who said my power steering control module had to be replaced at a cost of $750 dollars. Was aware of a recall for 2009 G-6's for power steering, but dealership seemed to have no information regarding recall. Was told that my VIN was not included in any recalls. Contacted GM, who told us to wait for a new round of recall letters to be distributed. In the meantime, it takes 6 days for the repairs, and only after significant questioning did the dealer admit that parts were hard to find due to the recall. We asked the dealership to let us have the faulty part to pursue action from GM. Dealer told us they had thrown parts away, despite this being against GM protocol. They located our part after we pushed them to investigate (car had been repaired that very morning, parts had not been thrown away), and assessed a $100 core charge. Have been bounced back and forth between GM and dealer since, with no responsibility taken by either party. Most recently, GM said they will not pay for reimbursement, and dealer said the parts they repaired were not recalled so they are not responsible either. As these parts are unlikely to break without cause, and don't need frequent servicing, it's clear that they are faulty. This is a major safety issue. GM needs to reexamine their recall.

On two separate occasions the headlamp wiring assembly failed (first the driver's side, then the passenger's side a few months later). Headlamp wiring on both driver and passenger side showed evidence of high heat (melted wiring and plug) at the rear of the connector in headlamp assembly. Dealership identified this as "normal" for cars with daytime running lights. Car had approximately 57,000 miles at the time.

The driver side headlight has been fixed several times over the past two years. The light continues to burn out within weeks. The connectors are burning out also. I am scared to drive at night because I am not sure if the light will go out. I am the 1st and only owner of this vehicle. The interior lighting is also malfunctioning. The lights get low by themselves while driving. The radio monitor goes blank. This is all electrical. Please help! thank you updated 12/1/2014

2009 Pontiac G6 GT sedan. Intermittent problems with the following for the last year: Brake lights come on when accelerating and turn off when braking (doing opposite of what they should be doing). Cruise control and traction control system both keep going out. Sometimes it's just the cruise control, other times the traction control system turns off first which in turn disables the cruise control. Whenever the cruise control starts going out, the brake lights start malfunctioning soon after. I suspect this is an issue with the BCM (body control module). Front drivers side headlight keeps going out, but the bulb isn't burned out. Replaced bulb twice. If I smack the plastic headlight cover, the light comes back on. The wires don't look damaged, so I'm not sure what is causing the problem with the headlight.

My headlight on the passenger side of my car continually goes out even with a new bulb. New bulbs last maybe two weeks and then the light shuts off, and will turn on only if I hit the light. I have spoken to several other G6 owners and they have had the same issues with the passenger side headlight. I have a 2009 G6 GT with approximately 118K miles. This issue has been going on since approximately 85K-90K miles.

The headlight went out, could not replace it, took it to the dealer and was told it was an electrical issue and the repair would not be covered by the warranty. The dealer fixed it about a $180. The headlight went out again in March 2013, at first it kept clicking and could be put on again by hitting the light cover but then finally went out. That light was never fixed again until May 2014 when the state inspection was due, the fix lasted less than 24 hours and now the car is back to having only one headlight.

2009 Pontiac G6. Problems with ignition switch. Fails to start car. May not be able to turn steering wheel. Cannot turn ignition switch to any position. You have to jiggle the key to eventually start vehicle and this may not work at all. My scenario points out that gms recall is not up to date on all ignition switches and further accidents will occur. There is currently no recall on this ignition switch. Updated 6/27/14

The low beams say on anytime the car is motion because of the day time running lights and the wires for the H11 bulb connector melt from over heating. The wire is not heavy duty enough to be day time running light. I've replaced both headlamp because of this problem and soon I will have to again. It is ridiculous.

Rear passenger door will not lock/unlock. Heater on front passenger seat will not work. Tire service monitor comes on randomly. Cruise control works intermittently, but does not work more often than it does. Loud, rubbing noise coming from steering column when making turns. Low beam headlights work intermittently (got stopped by a policeman and warned of a citation the next time I would get stopped). I had one bulb changed. Two weeks later it went out, but the bulb was not burnt. Then, it started working again. A month or so later the other one went out. I had both wiring harnesses changed and new bulbs put in. Recently, I was told I had a burnt headlight (low beam again). I have been stopped on the interstate to be told that my brakes were flashing (while driving) and then they were working opposite of what they should be (brake lights on while driving and off while braking). I have seen other Pontiac G6's with the same issue. This is a very dangerous issue in my opinion as I could easily be rear-ended due to faulty brakes. I have read similar issues by other Pontiac G6 owners. Will recalls be issued for any of these issues? I am a single parent and do not have money to pour into this car so most of it stays broken! sad considering I paid over $26K for this car and still owe over $10,000, yet it's worth probably $7,000. I can't even sell it with these issues!!! I would love to travel, but I don't even feel safe in this car any longer.

Was on thruway going 65mph car shut off for the third incident in approximate of a year from other 2 incidents. This time was or could of been killed due to this problem due to rate of speed and where I was driving onto an on ramp where I broke down.car dealer replaced engine control module #12612397. I no longer feel safe driving this car because I know this will happen again. I think this vehicle should be added to the recalls going on with GM because the same thing is happening to my car.

I see that there is a recall for this very issue for years thru 2008. My brake lights are on when not braking and off when braking and of course the cruise control will not work during this issue. I see many complaints about this and I find it so hard to understand how this cannot be a safety issue and recalled to fix. I have almost been rearended many times and am wondering if someone has to be involved in a fatal accident before the nhsta forced the expansion of the recall to include all years that are having this issue.

I have 2009 Pontiac and I have replaced the headlight like five times still doesn't work were I live I see alot of the same car with the same problem. I already had the latch for shifter replaced cause it went out while I was driving seeing all the things that can go wrong as the post of everybody with headlight brakes the engine I think the whole car should be recall before alot of people get hurt its a death trap all kind of things wrong with this car and in this day and time people don't have the money to keep fixing a car that has so many problems not by wear and tear but by not properly putting it together my car was 16,000 dollars and to pay that much and have so many problems is ridiculous.

Low beam light on both the driver & passenger sides keep going out. I keep replacing and immediately they go out. Bulbs were not burnt out. Every once in a while, while driving my headlights will randomly come on and go off again. The metal in the connectors are fried. I have researched and read multiple reports of the same issue that this is a wiring problem and a fire hazard. Something needs to be done about this before someone gets hurt or there is a fatal accident. Not only is this a fire hazard, but intermittently working headlights could cause accidents if randomly going out. It is clearly a safety hazard and Pontiac should be held accountable for this problem.

While following my wife in our 2009 G6 I noticed that she was ridding the brakes. When I asked her why she said she wasn't using the brakes at all. The brake lights are coming on and staying on even when the brake pedal is not depressed.

While operating vehicle, brake lights work the opposite of what they should. They are on when the pedal is not depressed and go off when the pedal is depressed. I spent ~$300 having the brake pedal position sensor diagnosed and it turns out that the BCM (body control module) has corrosion and required dielectric paste to correct the issue. Approximately 14 months later the problem returned and I had a mechanic check for recall and he found a tech bulletin describing exactly this maintenance procedure. They performed it and the problem was corrected but this needs to be 100% corrected as someone is going to get killed. Searching forums online I see that this problem is far more common that one would think and this should be addressed immediately.
