| I have encountered several different chevy/gmc vehicles that are experiencing a lagging start and in some cases no start without a boost. my sonoma has the lag and i have a few friends that have blazers and full size trucks as well. the variation of engine sizes that are affected has me perplexed. i have attempted to run codes with no fault results. this occurs every time i attempt a startup. *tr | |||

| Not sure if belt broke first or fan blade the blade broke off and flew inside of truck causing damage to parts under the hood it was 1000.00 to fix all the parts broken by this. i have all the old parts. the belt was ok but something caused the blade to brake off and there are noticeable cracks in the blade around the nut. because of this failure i had to replace a lot of components under the hood. *nm | |||

| 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! *ak | |||
