Great truck, still getting used to the new front end grill( I liked 99-02 best) I previously owned a 2000 z71 sierra slt. Just bought 2004 SLT 2500 crew cab 4x4. They dont include under the hood courtesy light, they eliminated one of the cigarette lighter power input. the 2004 has 6l vortec which is a huge pig compared to 5.3 vortec in my old 2000. the new computer stuff is pretty cool. I am getting on average 10mpg on the 6 liter, I used to get 18- 19 on the 5.3 motor. The first thing to go will be the air cleaner swap with an Air aid or K&N type of element. dramatic horsepower and fuel economy increases should be expected.
Great truck for work or play

I picked this up to replace a 1999 Dodge Ram 2500 V10. I use my trucks for towing my toys and for getting to my hunting camp. I bought the GMC used with very low (50K) miles and I received the service records. The previous owner had a few problems with the worst being the door handle. I have had no major problems. Mine is the 3 door 2500 4x4. The interior is good with very comfortable seats. The seats have some play in the tracks and I have a kit to fix it, but never got around to doing it so I'd rate that minor. Gauges are great with tranny temp and steering is good. 4 wheel disk brakes are excellent. HVAC works well and has not had any problems. Ride is above average. Fuel economy is 15 -17 with the 3.73 gears. The 4L80E transmission (TH400 descendant) is excellent and is heavy duty. It has push-button 4x4 shifting. Auto, high, and low. You can from high to low on the fly, and to low below 5 MPH. Auto works well on wet roads. My 4x4 shifter has not malfunctioned. Mine has the rear locking differential and gets through sand very well compared with the Dodge. This truck has a nice off-road feel and feels very capable The 6.0L LQ4 engine does make the piston slapping sound at start-up, but goes away when warm as designed. Engine makes good power, but power is a bit too high in the RPM range for serious work with the 3.73 gears. This model uses the power steering pump to boost the brakes and my unit had a bit of a leak. Flushing the power steering unit with Prestone anti leak pwr steering fluid fixed it. The stock radio is below average and the speakers were blown when I got it. The body has not rusted, but the black paint is starting to fade on the hood. The 3 door is kind of a pain just having one door and when putting groceries in the back seat since you can't fit the cart in the opening. Other than that I like this truck very much. I've only performed maintenance. Oil every 3K, brake flush, transmission flush, and diff fluid changed.

rear brakes and parking brake leave something to be desired. Rear rotors rust decreasing overall braking power and make the parking brake all but useless. Good power and excellent towing vehicle for horse trailer. Two piece drive shaft failed during our second towing excursion. Dealership replaced with a single piece unit. Now it hums while you drive but has proven to be reliable. Unit stuck in 4wd during -20 degree weather. Again dealership repaired. Dealership was cooperative in making repairs.
Worst truck I'e ever owned

Truly a masterpiece of "poor" engineering. 2004 sierra 2500 with a duramax diesel and Alison transmission. Had to replace the intermediate steering shaft the first year. The vehicle constantly looses prime and shuts down. Here's the kicker . The oil pressure gauge flutters and the annoying chime rings constantly indicating low oil pressure. The cluster panel has been changed twice, the oil pressure sending unit has been changed three times. They even changed the oil pump? Still, no fix. This truck has been a nightmare from day one!
Not Happy!

This vehicle became a nightmare after about 10,000 miles. First the steering shaft failed ... ? That's right, the steering shaft! Next the instrument cluster had to be replaced since the low oil pressure warning kept chiming. It still chimes uncontrollably after replacing the oil pressure sending unit three times, the oil and filter five times (when it didn't need it), and get this ... they changed the oil pump and the thing still chimes at will! The truck rides like a tank. Now the steering gear box needs to be replaced. There are less than 85,000 miles on this pig!
