I lost my low beams about a year ago and also one high beam. Just one month ago that headlight went out also. I have read that there are wiring problems r/t the Pontiac G6. I am unable to drive my car at night without headlights. The fuses, bulbs and relay switches are intact and working. My mechanic says it’s a wiring problem. Is the manufacturing company responsible for this kind of problem? Other electrical issues are present. When my seatbelt is on I get a message that it is not. Sometimes if I wiggle or reinsert it the light goes out, but more often than not it is on. I also get messages that says my airbag isn’t working on drivers side. The check engine light goes on and off if I hit a good size bump. I also had a mechanic spray WD40 under my drivers seat and that made the check engine light go out for several months.

A few months ago, I was pulling out of a parking lot and started to brake , but my car was not stopping. I quickly pumped my brakes and then my brakes worked. All my brake lights came on; ABS, BRAKE, TC, Check engine; and car maintenance light all came on. They periodically would go away but would return when it rained, or if the brakes gave out. Brakes have gone out twice, once while driving on freeway. Before this issue, I had taken it to a mechanic as the brake light was on, and the ‘brake fluid’ message was on my dash- the mechanic scanned it and said the BCM was malfunctioning, to take it to the dealership. I knew who bought the car originally off the lot, so I knew the specific dealership it was bought from (gmc dealership). When I called and told them the issue, they said they will not touch my car (exact words). It’s no longer under warranty and that they would not work on the car regardless. I took it to the main GMC dealership in my city, where they said it would cost thousands to diagnose and fix the car properly, even though I told them I knew what the issue was and what part needed replacing. They confirmed my cars issue was what I said it was, but said it would be VERY expensive to replace and fix, so I decided not to repair it (as the price was not what they originally told me). Now that the brakes fail periodically, I started looking around and saw others had similar issues.

Electrical issue with my pontiac g6 I have had to replace my headlights bulbs multiple times due to the plugs melting I have actively seen the plug smoking and it has happened on both of my drl/low beam headlight bulbs resulting in plugs having to be replaced multiple times as well. My engine light isn't working and yet I have engine codes my service air bag light comes on at random my buckle seat belt light won't go off it stays on when I'm buckled in the driver's seat. My pressure sensor on my fuel tank has low voltage issues. When shutting the car off and opening the driver door all accessories that should of shut off are still active including the radio. The oil light is always turning on but the vehicle isn't low on oil nor does the message appear. When plugging in a car scanner the anti theft system light turns on and at random times will shut the car off. When the car scanner gets plugged in the rpms drop for a second and then go up as well. At times only one of my headlights work and I have to smack the headlight that isn't working to get it working.
