2004 GMC Sierra 2500 consumer reviews

First , I bought gas 6.0 , the diesels are great if you have serious towing needs. You just need to realize no matter how well you maintain a diesel it will at some point have an expensive repair. I've had my truck about 12 years. Regular maintenance , a few batteries , couple sets of tires and a MAF sensor. I tow a couple different trailers and the heaviest is less than 10k loaded. Towing , zero issues , no band aids , no overloads , no equalizing hitch , no sway control. Simply not needed. Drives amazing, stops great, Roughly 10 to 12 MPG towing. Unloaded driving at 60 / 65 on cruise solid 15 to 16 MPG. Yes , it won't pul the hills like a diesel but thats a small price to pay for an absolutely amazing truck. I want a new truck in the worst way but just can't part with this truck. A very good truck if you find a clean well maintained one.

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.

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

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.

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

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.

-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.

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