Underhood Wiring problems of the 1999 GMC Sonoma

1) boyfriend driving, pulled up to intersection, truck stalled, restarted, died, noticed smoke, opened hood, fire near battery and antifreeze container, put out with snow, vehicle towed to dealership, contacted gm, told a rep would contact me within 24-48 hours, that was a week ago, no call, vehicle just sits!! 2) abs light on, told by dealership to make appointment, not a big deal. When light was on that was true, but light didn't always come on and it was like a brick was behind the brake. Had to slam on it! not good on these winter roads. Dealership did replace left wheel speed sensor harness. 3) noticed oil leaking slightly, dealer replaced engine oil cooler lines 4) stuck in 4x4. Dealer replaced trasnfer case encoder. Said common problem in cold weather. However, only had one cold snap, vehicle is brand new, thought this was unusual. 5) third door handle broke when opening. Replaced by dealer. Trick to opening is having to push in on door before squeezing handle. Forgot to tell trick to other people, and when they tried to get into vehicle, broke handle again. Dealer replaced again. Still have to use trick to open. Could easily brake again!.
