 Some of the items forthcoming happen all together and/or intermittently separate. the initial issues noticeably started upon my arrive in south carolina, but it was not something that immediately recognized before my relocation, because i thought it was something i did myself. i came out to my car on saturday, 6/16/12. my car window was down and some items were stolen. i did not see any glass on the ground so i thought i left the window down myself and someone just stolen items. after speaking with the complex security and reporting the incident to hoa, i came out the truck again it smelled of wires burning and the window was down again. several days later the tire pressure light was on and took the truck to get the wheels balanced and oil change at firestone. the tire pressure light would not go out, nor did the engine and oil light go out. a few months after that the smell of wires burning happened again and the engine remained on for over 2 weeks, then went off. in the late fall there was a really bad thunderstorm and when arrived to truck after work; running in rain, i saw that my window was down and i could not get the window back up for about 5 minutes. i was soaked and so was the car. the truck received an oil change recently and all the lights would not go out and the walmart mechanic who did the oil change stated that he smelled gas and some wires burning, lights on panel would not go out. smell of wires burning. engine light comes on and stays on for days-then goes off by itself. all lights emergency lights on panel intermittently on (oil/traction/tire pressure). fuel gauge shows/clicks as full, smells like gas in truck and runs out of fuel with gauge showing full. driver's window goes down when keys are not in truck. heating knob on off, still blowing hot or cold air and gauge does not turn on past 2. lights dim when using power button for windows. *tr

 The fuel gauge level indicator just went from full to empty, it just went that fast. minutes before it had just been filled at the gas station. when starting, the gauge rises then falls to empty. on occasions the warning message, please tighten gas cap comes on. now months later, same problem; after contacting gm hotline, they still have not shown any concern. i keep track of miles driven since last fill-up and gas used, so i know when it is time to fill-up. i have read many same complaints, and i wonder why gm has not issued a recall. it is now 08/21/2012 and problem is still ongoing. can you please help. please. gm has on numerous occasions suggested that the wire harness on top of the gas tank needs to be replaced, to do so, requires a five (5) hour visit and they expect the customer to pay half the cost. please help.
