  During the first 3 months my truck was in the shop 6 times. Radio would not return CD, without it for 3 days. Once for extending camper mirrors, passenger side motor bad. Once for A/C, recall part not replaced prior to purchase. Three times for 4 WD, computer chip keeps going out and shifting into 4WD low on its own regardless of speed. Ill go back to the Ford F-250 with the V-10. More power, better gas mileage and reliability.

  Good but could be better! - 2004 GMC Sierra 2500HD

  Thus far its proven to be what was expected. I do like the pick up power and acceleration power, the turning radius needs to be inproved. Another plus would be to install a rear window that is fuctional. Heat controls for the rear needs installed. Overall the performance, handling, and appearance are what I expected. Ive named it the HULK, its big, its green and its powerful!

  I am pleased with my purchase at this time. It tows as is expected for a truck with its power- it is capable in the woods and farm as well as on the highway-- though the fuel economy is a jolt. But then again it is alot of weight to move.

  Truck has been overall a good unit. Windsheild leak when new at passenger floorboard and behind dash. Took 1 year for local dealer to finally fix. Climate Control slow to activate fan, really noticable on hot days, seems I have to press brake pedal to start blower (wierd). Trans will sometimes start in 2nd gear, then shift to 1st. Usual problems with intermiediate steering shaft (now on 2nd fix), drivers seat belt and armrest broke, pass side also (wrty fixes). Also having wierd problem during cold months with intermittent dash light and guages recycling, no fix yet. Orig brakes are still strong at 90k miles, tire wear good, body still tight and quiet, engine strong with no oil usage

  It was nice at $1.89/gal for fuel. - 2004 GMC Sierra 2500HD

  This truck has been used mostly on the highway, carries dirt/mulch and recreational toys. And has done so for 62,000 miles without a single mechanical problem! It was originally purchased for towing a camper. Within 6 months of purchase, rising gas prices made driving this thirsty vehicle downright painful! With the cruise control set at 65 station to station on an interstate,13.7mpg. Disappointments? The ventialtion system. The AC is not cold nor dry enough to defog windows. And the radio is horrible! Did I mention fuel efficiency?
