2008 Pontiac G6: key fob or push-button start problems

Filed Aug 19, 2021 · Body, Electrical · NH

The electrical harness going to the drivers door doesn't function properly in any way shape or form. My locks blow a fuse every time you hit the button my trunk pop works with my key fob but not the actual button. My passenger window only goes down if you open the door completely but then only goes up with the pass. Switch and my car radio stays on even if I shut the car off take the keys out and get out of the car... Me not being able to get windows down or trunk open in an emergency is extremely dangerous and unsafe in every way and so is the door locks not functioning properly.... I demand a safety recall be issued on the wiring harness immediately....

I noticed that my driver's side low beam headlight was out. I purchased a new one but upon installation, I noticed that the old one did not visually appear to be bad. I replaced it anyway. A few weeks later the same one was out again. I checked it for connection problems etc and it started working again. A few weeks later it was out again. Approximately a month ago, I was unlocking my doors with the key fob while parked in front of my garage door and noticed on the garage door that both lights were working; however, when I opened the door it went off and stayed off until I unlocked the door with the fob again.

Vehicle battery was drained overnight from consumer electronics (dvd charging, GPS) to the point when attempting to start near zero voltage with inside lights shutting off. Charged with 10 amp battery charger to full battery. Afterwards key fobs would not work. Did not think much of it. After a few days of driving noticed the tire pressure info was all -- (not posting). Tire pressure system monitoring was completely off with no notification to driver. Found several sites that say a g6 can lose it's tire sensor/key fob memory from a slowly draining battery and must be taken to a dealer to fix it. Took it to a gmc (formerly pontiac) dealership, $95 later only got the tires working again. Newer vehicles have a procedure for owners to initiate this setup themselves and reprogram the tires and key fobs, but not 2008. The lack of tire pressure sensors when they were there prior should trigger at minimum a warning on every start. It can tell me I need an oil change every day. For this to happen because of a low voltage event is terrible circuit design / bad programming. If an owner charges his kid's dvd player and it kills the battery the next day the mandatory tmps system may not work, and not work without warning. Hopefully the day the dvd player needs a charge isn't the same day they develop a medium leak driving down the mountains of utah, because the driver won't be notified the system forgot the sensor id's and doesn't care about those pressure readings anymore, even the falling pressure on the tire holding the car in the correct lane at a 8% grade, downhill. #1 fix the safety issue. #2 don't charge me to re-program something that is not safe and was corrected on newer vehicles.

Well it seems the problem that was supposed to be fixed back in sept. 27, 2011 with my 2008 g6 is back (11/4/2013) see correspondence below. I paid $113.14 at pete baur and the problem is back at 75,000 mile (only 20k miles later). The car is a hazard to drive. The brake lights stay on until the brake petal is pushed. Then they turn off. What a messed up way for a safety system like brake lights to fail. The cruise control doesn't work anymore. I also had to remove the third brake light fuse because the third brake light would stay on all the time and the the car would be electrically dead when I would go to start it. The battery was not drained at all. It would just be dead until I gave it a good jump. And another thing the key fobs are totally messed up. They barley work anymore. What a piece of junk this car is. Oh, also the sevice traction control come on randomly. I can't beleive no one has been injured yet. If I could afford to buy another car I would. I don't let anyone else drive this in my family. Gm - never never never never again no matter what they are selling.

I just bought this 2008 pontiac g6 4cyl automatic for my daughter. Everything works fine except - both rear doors will not lock or unlock electrically and nothing works from a key fob and the dealer could not program it. The rear doors must be manually locked, or unlocked. Also, cannot lock or unlock rear doors from the front door switch. Both front doors do lock and unlock properly by the door switch and the park positions, but not the rear doors. The remote keyless entry will not operate anything and the dealer stated I need a new body control module to program the key fobs. The car has the remote keyless entry ap8 code and the dealer said a remote should work after programming, but they could not do it. I paid dealers $200 for scans only to find out the function is locked, they say. And now dealer wants another $550 for a new bcm and approx. $100 for a new remote key fob, and maybe about $300 or so more for both rear door lock latches replaced. I declined. Due to numerous complaints about this problem, it seems to me this should be a safety issue and a recall or a fix at no charge by gm.
