2010 Chev Cobalt LT- Electrical Problem...

Hi All,

I have a 2010 Chev Cobalt LT, bought brand new off the lot- at about 15,000 km's, I started to experience some electrical issues.. Basically, what it is the parking brake light comes on in the instrument panel along with the all the other warning lights, both speedo and rpm gauges stop working, -- basically EVERYTHING electrical, but the lights, and turn signals, hazards work-- took it in to the GM Dealer- they cleaned the BCM Connectors, it was fine for about 4 months- now it's doing it again... Same thing as before warning lights come on, and everything stops except last night the Keyless Entry would not work at all... This has me stumped and it's annoying having to take it all the time.. Anyone have any ideas?
