NHTSA — Electrical System Problems

2009 Pontiac G6 (Page 2 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.

Drivers side headlight went out while driving in very bad weather conditions at night. Replaced bulb and it worked for 2 days before the same thing happened. Replaced bulb again and it worked for about 10 days before it happened again. Now learning that this happens a lot on this car because the harness connector is melting and needs to be replaced but due to constant overheating it will not permanently fix this problem. GM knows of this problem but deems it not their responsibility. Does there have to be a fatality before Pontiac/GM takes this seriously?

Issues with low beam headlights randomly going out then coming back on at first for a couple of months, then went out completely. Replaced bulbs (low beam) with same problems. Finally found that the low beam light sockets (primarily passenger side) were arcing and shorting out causing bulbs not to work. Recall should be issued to have GM remedy this problem. This is a chronic problem with this line of cars!

Head lights keep going out...the wires connected with the low beam lights are burnt and corroded. I have replace these parts 20 times since 2009. This time on January 1, 2015 the wires and connectors are to burnt to repair and the dealer ship said I will have to buy the whole harness kit assembly instead of just the wires. Why should I, this problems is far and wide on the internet with the Pontiac G6. I travel with my job and I have experienced multiple times both headlights going out on me and I had to use the high beam just to get home. Please let GM know and issue some kind of recall before I die on the highway due to these faulty headlight wires.

The drivers side, low beam headlight has been replaced several times. The wiring harness melts! this seems to be a common complaint with G6 owners.

2009 Pontiac G6 passenger side headlight would intermittently go off and finally stayed off. After removing the headlight assembly, I found a melted connect to the light bulb itself. I found a replacement connector at Napa auto parts and replaced it. It worked for 3 weeks and went out again. Upon opening up the light, I found the new connector melted again. There is a wiring problem causing this connector to overheat. Safety concern is if both fail over time, the driver will not have any headlights for nighttime driving. Also, the headlights are part of the daytime driving lights.

The dim headlights keep going out I have replaced them 3 times and still go out I believe it's in the wiring because if you hit the headlight they will soon come back on. I've read the wiring harness gets to hot and melts the wires seems like a fired hazard to me.

Unfortunately I have experienced about all of the issues that are being complained about on here. The light connectors melting and blowing the headlights, the electrical system messing up and frying 7 brains, the brake lights not working properly, the steering acting funny just to name a few, and although I have taken the car to the dealership several times since 2010 to have these issues worked on, I continue to have the problems. I think that it is ridiculous that car manufacturing companies are allowed to let these vehicles stay on the road without doing recalls on these dangerous and possibly fatal problems. For years I wanted one of these cars after they came out and now it has been the biggest waste of my time and money. But..that's ok! as soon as I have a wreck or something happens due to one of these problems I will be dialing up my lawyer!!!

The driver side headlight burned out. I checked the bulb, and the connectors were burned and melted on the light as well as the harness. I changed the harness myself, and the same thing happened approximately one year later. There is a severe malfunction in the electrical component of the headlight system. I am afraid if this continues to occur, it could start a fire in the vehicle. Possibly while it is being driven.

Driver side low-beam headlight not working. Replaced bulb in 23 November 2013 and again on 5 October 2014. Light went out again on 15 October 2014. Dealer replaced headlight lamp socket as socket was burnt out. Internet searches show numerous issues with Pontiac G6 headlamps having issues with headlight lamp sockets... electrical arcing within socket causing carbon build up and lamp failure. This should be a recall item by GM on this vehicle to fix this safety issue.

On October 7, 2014, as I was waiting for the stop light to change. My car turned off and then on again. On the following day, after I parked my car, I went to start it, and it didn't crank at all. I went to get the battery, starter, and alternator checked, they all passed with flying colors.

I was driving down the road when the driver's side headlight went out. I have replaced the same headlight at least three times. Today, 26 Sept 2014, I attempted to replace the headlight bulb again, but found that the connector has melted. I'm concerned that my other headlight may go out while driving, so I will see what the dealership says after the vehicle inspection. I have heard that it can cost between 400 to 500 dollars. Please have this investigated before someone gets hurt or killed.

As I was driving towards my home after dark, my drivers side headlight (low-beam) went out. Because I was on a rural road, I turned on my high-beams. In less than a minute an I went back to my low-beams due to an oncoming car and I had no low-beam lights at all. I immediately turned my high-beams back on so I could be seen by the other car. After returning home I informed my husband of the problem. The next morning he checked the headlight lamps and found that the electrical plug/sockets to both low-beam lights were shorted-out, burned, and melted. While at a local auto-parts store trying to get replacement pig-tails to repair the lights I talked to one of the sales persons who also works at a local GM dealership. He told me that they see 6 to 10 cars a week that have had this same problem. This is a very dangerous situation and it appears to be very common.
