NHTSA — Electrical System Problems

2009 Pontiac G6 (Page 7 of 9)

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 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.

I have a 2009 Pontiac G6 GT. Since the time that we have bought our car we have had nothing but problems with the passenger side headlight. We have replaced the pigtails and all the wiring. We replaced the bulb every few weeks for it to only burn out a few days later. No one can tell us why this problem can not be fixed. There have been hundreds maybe thousand of complaints on online forums about headlight problems and even fire and melting of the housing. I am constantly pulled over due to the headlight being out. This is an extremely dangerous issue that needs to be addressed. Without properly working headlights people are going to get seriously injured or kill someone because we can't see properly.

Less than a month ago I replaced my passenger side headlight. This week it went out again. I have already had to replace the driver side light about three times. I bought this car brand new. I changed the fuse for the headlight and it did not solve the issue. Two days ago my tail light stopped working. The following day it worked in the morning and stopped working in the afternoon. After finding so many complaints on different forums online I'm not sure how GM can not be recalling these vehicles for this problem. I have already gotten pulled over and told that I would be cited the next time. I am afraid that the driver side headlight will go out before I can get the passenger side fixed. Oh yes and my lock chamber on my passenger side back door has gone out. I had the driver side back door fixed when my car was under warranty however, I am on a tight budget and cannot afford to pay over $300 for the dealership to fix this. Apparently this is also a problem with the G6. I am nervous to drive my car (that is not even 5 years old mind you) at night!

This is on my daughter's car. I was following her and I noticed she was driving with her foot on the brake. I motioned her to pull over and asked her why she had her foot on the brake. She said she was not driving with her foot on the brake. Upon further investigation I found out the brake lights were staying on when the brake pedal was not depressed, but when she depressed the brake pedal the brake lights actually went off. This is an extremely unsafe condition. Doing research online I have found many other Pontiac G6 owners with the same problem. This needs to be addressed and fixed by GM.

When traveling above about 10 mph the brake lights came on and the cruise control no longer worked. When the brake pedal was depressed, the brake lights went out until the car slowed to about 10 mph at which point the brake lights came back on. Braking was normal at all times. When pulling away from the stop, the brake lights came back on again around 10 mph. The car consistently did this over a trip of about 60 miles. When I took the car into the dealer, the issue wasn't present. The dealer replaced the brake switch and lubricated a connection. The issue has returned 2 days later. This issue could become dangerous especially during braking above 10 mph when following vehicles would not be aware that the car was braking.

2009 Pontiac G6 low beam headlight failure: "unable to find the problem" as beams work intermittently; my local mechanic replaced left light bulb, but referred me back to dealership as "this was a known defect in this car." Replaced light bulb (repaired (mechanic was unsure, but replaced anyway) and low beams worked a couple of days, now one (right more randomly left), and sometime both low beams fail intermittently. My wife has received one warning from police; headlight was working again when she restarted car after the warning. With increasing frequency both low beam head lights fail while driving at night. These random failures in low beam illumination requires the driver (my wife usually) to immediately switch on high beams. Both high beam lights are working at this time, but these events tend to infuriate oncoming drivers who high beam back at us, so both drivers are blinded. In my opinion, this vehicle is unsafe to drive at any speed at night or in the rain due to random low beam headlight outages. Therefore, we use of the G6 is limited. Though we like the model and had hoped for several more years of use, my wife does not trust the lights will stay on at night, or when it rains. I feel bad about dumping this car on the used/pre-owned car market without filing some form of official complaint. From a brief internet search, the manufacturer (GM) appears to be ignoring this safety issue as a statistically insignificant problem. Sadly, GM will continue to do so until people die and a class action suit is filed. I would not call the Pontiac G6 a lemon, it is just plain too scary to drive under certain conditions. There does not appear to be a solution coming from GM and my mechanic can't fix it. This situation makes this vehicle useless and unsafe half the time, I.e., unsafe at any speed after dark!

My 2009 Pontiac G6 rear brake lights are working opposite of how intended. When the brakes are not applied the brake lights remain activated, when I depress the brake pedal the brake lights turn off. The cruise control is also inoperative, most likely linked to the brake light issue. I called the dealership where I purchased the vehicle new and was told that nothing would be done about the issue because the warranty was over. I asked for information on how to repair the issue myself and was told none was available. Someone is going to get killed over this issue if fatalities have not already occurred.

My brake lights are intermittently staying on while driving even though I am not using the brake pedal. The scary part is that they shut off when you hit the pedal and then come back on about 5 seconds later. I saw on the web that there is a known problem with corrosion on the BCM connections. There was a recall for previous years and GM has issued a technical service bulletin on how to fix it because there have been so many problems and complaints. I am going to try a quick fix I found on the Pontiac G6 forum before I have to take it to a dealer and spend my own money on an obvious defect.
