Bought the truck in october of 2009, took to dealership on 12/17/2009 with complaints mileage of 96,764 of low engine power, hard to start truck,,,,glow plugs were bad corroded park neutral switch, corrosion on brake lines..paid $ 3,600 in repairs then around late september 9-28-2010truck died a fourway intersection...was almost hit by a car...towed to nearest service fleet source...found out injectors were bad...work was started for repairs...then i found out the glow plugs...which i paid for already...and the injectors were service bulletins...called fleet told them to stop repairs...called the dealership...that had the truck in december...ask why they charged me for the glow plugs and why the did not fix the injectors...when it was in there.....dealership hung up on me...called 1-800-790-5700..spoke with gm told them about my chevy problems...they claim that my injectors would not be covered...as it was not a dealership....funny thing is that fleet source is a certified rebuilder for bosch, and satadyne by the manufacture for these parts that are used in all gm vehicles....so if you take your truck to a dealer...they get their parts from these people.....gm has a history of putting on bulletins for items...and claiming when you bring in your truck that the part does not meet the perimeter for replacement....i about another $ 3,200.00 that makes about $ 5,0000.00 dollars of items that people have complained out...had recalls..service bulletins....never will by anything that gm make again. *tr

Bearing in front axles came apart. causing metals to go through all of the front differential drivetrain. complete front drivetrain needed to be replaced. truck was 1500 miles and 2 months out of warranty and dealer could do nothing to help out with cost of repair. this bearing should have not came apart. fluid levels were good, no leaks, and maint per manufacturers schedule was always performed. *tr

Injectors number 2 and 7 loose connector and oil pump rubbing through transfer case on chevy silverado hd2500 traveling down the highway pulling a horse trailer the truck went into limp mode and would not keep up with highway speed. had to pull over on an interstate and attempt a quick repair along the road. transfer case has not yet caused a problem, however, the aluminum residues in the case oin are very high and when pump goes through case all oil will be lost and the vehicle will stop. *nm

Left rear-axle seal has blown a total of 4 times. the brakes were soaked with axle fluid each time and we were told that it could catch fire if brakes got hot enough. the brakes have smoked, but have not caught fire yet! the axle-seal was replaced by the manufacturer under our warranty. the axle assembly needs to be replaced to stop the problem but, the manufacturer refuses to do this. *jb
