Was sold a pack of lies

I was told this truck had been well maintained just to find it had been modified by someone who didn’t know what they were doing AND the transfer case was bone dry and even had dirt in it. Was told it was rust free only to find rust painted over.


This is my second GMC Sierra but my first with a D

Absolutely love these year GMC early to mid 2000's so dependable and comfortable to drive, just an all around American made truck I wish they would go backwards and start making this style again


Solid Truck

This truck has been really good. It pulls my camp trailer with no problems, very comfortable on long trips, it looks like I will have it for a long time.


great truck for the money.

truck makes great power, pre emmision diesel, and an Allison transmission. tons of interior room, very few common problems arise from the lb7s.


Very reliable pickup

I purchased this pickup 6 years ago. Never once did it break down on me or left me stranded. Mileage is about 13 to 15 based on speed. Very powerfull engine and frame. Hauls very well. Only issue is speedometer gauge issue with 03 to 07 GMC where it can on few days show incorrect speed because gauge cluster sometimes gets stuck. The gauge cluster is about 300 dollars. Other than that, a wonderfull long lasting 4x4 pickup that will not disappoint.



Contacted dealership on a sunday thru email and I have never ever received a response. They must not want to sell a vehicle very badly.


Great weekly commuter & weekend workhorse!

-This windy input is based on some years of owning various makes & types of trucks & 4x4s prior to purchasing my 2004 GMC w/22K miles in 03/2005 (paid ~$20K & new sticker was $33K)... -7-years later, my base-model non-HD 2500 4x4 has 156K mi. Its aerodynamic design with ext. cab (doubles as a toolbox), LQ-6.0L, & 4L80 trans. has endured workloads that have stranded other trucks while averaging great 3/4-ton truck economy (city-15mpg & hwy-20mpg). Unloaded, the truck effortlessly spins its tires & refuses to downshift while maintaining a ~70mph cruise on hilly hwys. -Routine maintenance & upgrades on this truck can be easily & economically performed by average wrench-turners w/reasonable computer literacy; added to the fact that the GM Vortec & LS-type engines have only improved, adding to increased 2nd-hand & aftermarket support. -Aesthetically, I'm not crazy about the under-bite front bumper or needing fender flares for slightly wider wheels & tires, my cloth seats still look great, but my console lid is now a lift-off.... -I've replaced the recalled gauge cluster & steering shaft. I've also replaced the front hub assys, power steering pump, rear-diff seal, water pump, & crank sensor. To improve fuel mileage, I lessened the intake & exhaust restrictions, lowered the engine & trans temps, upgraded coil packs, & still perform routine maintenance. -From my perspective, automotive wear & tear is so subjective that the true measure of reliability is predictability of failure (not leaving you stranded), coupled with, ease & economy of repair. On that note, it has been my experience that using GM & AC Delco parts will minimize the frequency of repair(s), but bang-for-the-buck, I count myself lucky to own such a great vehicle that doubles flawlessly as a 4wd truck!



These vehicles have the worst made parts ever.Makes me want to buy foreign only!No heat when it was cold and too much heat when its hot out.Very expensive to repair heating and air conditioning.You will have to take out a mortgage on your house.Many things went wrong with the one I owned.


reliable truck

it's awesome, incredible. ...........................................................................


Will never get rid of this truck!!!

GMC has hit the nail on the head with this one. Great truck, comfortable interior, powerful duramax diesel and stunning looks. This is far and away the best vehicle I have ever owned and will drive it til the engine goes or the wheels fall off, i am betting on the latter. Bought truck used with 88k miles and now have over 140k. Only issue that I have heard from several people is the torque converter lugs cracking. In a truck this powerful it has to be braced. Had mine replaced after it craked at 105k, been rocking on ever since. 4x4 is amazing and can go anywhere or pull anything. good leg room in back seat, heated seats are nice. GMC duramax is the only truck i will ever purchase.
