09 G6 GXP Major Electronic Issues
New member here,
I ran across the site while searching for help in regards to issues I am having with my wife's 2009 Pontiac G6 GXP Sedan. Several weeks ago, the A/C quit working suddenly. First we thought this was the only issue and must need some AC work done...however, as we drove it a bit more, we noticed the gauges on the dash (speedometer, rpm, temp, etc.) would suddenly "0" out and then resume working randomly with no explanation while driving. Then suddenly while this would happen the radio would cut out and all the center console lights would go out all at the same time for 15 seconds at a time. Sometimes it would all start working again and be fine for 10 minutes, other times it would start to cut out again as soon as it turned back on. Operation of the vehicle as far as driving works fine, no loss of steering, power etc. We also began to notice the keyless entry would sometimes quit working & the automatic start would not work from time to time. I was just about to take it to the shop, but then it all started working again just fine. It worked great (including the AC) for about 2-3 weeks.
This past weekend we took it on a small road trip and guess what....it started acting up even worse than before. All the same problems exist as they did before, but it seems like it is doing it much more frequently now than before, and there were a few times that we would stop where I turned the key over and it didn't even act like it wanted to try to start (no noise, turnover anything). As soon as I would try it again it would start right up. It is very confusing and frustrating, and I am going to take it to the shop soon. I just wondered if this had happened to anyone else, and if so...what the issue was. I have had a few people tell me the BCM needs to be replaced. Due to my wife commuting for work, I am outside of the bumper to bumper by about 10K miles....just my luck. Any help or insight would be much appreciated!
