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.

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.

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

2004 GMC Sierra 2500 4dr Crew Cab SLE Rwd SB (6.0L 8cyl 4A)
4 of 7 people found this review helpful
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!

I have the 2500HD 6.6L Diesel 4x4 Crew Cab SB. This is my third GM 4x4 truck, but first diesel. I tow an RV and put dirt bikes in the back and it drives like I have nothing attached and nothing in the back. I can accelerate going up hills on the freeway fully loaded towing the RV. The interior noise is quieter than my wife's Chevy Blazer. The stereo absolutely rocks, and the seat heaters are so nice - even in San Diego CA! This is the best truck ever made.

I like my GMC very much,it is snappy and has good torque for pulling a medium weight travel trailer. The only complaint I have with this truck is a persistant knock in the engine that is very noticable in the morning starts. My previous truck was a 1976 3/4 ton 4x4 GMC long bed. The ride on the 2000 was my first consideration in buying a new truck. My next step up will be the Duramax.
A Nice Truck!

We've driven a 2004 Sierra 2500HD(crew cab)for about 1000 miles. Roomy, excellent fit and finish and performance. I really like the instruments, (XM radio-rocks!) and seat belts. Yes. It's a nice touch to embed the belts into the front seat backs. Gas mileage is average-13.5 mpg here. The instant fuel economy readout helps optimize mpg. We use 88 octaine. GMC convert. Nice Truck!
Great Power with 6.0 liter

ABS electronic module - replaced by dealer in Virgina only problem. Drove 300 miles to pick up - has one of first 6.0 liter engines. Great power. Engine does not show up as option in parts stores until 2001.
Service 4WD Light

4WD light comes on intermittently lately. Poor troubleshooting procedures from a Chilton manual led me to replace the front diff actuator motor. Seems the real culprit is a sticky selector switch. Humidity may be affecting this switch, apparently the resistors are shot for each position and loses ability to keep voltage signal to transfer case module. Original battery lasted 6 years so that was awesome to get over 6 years from a battery. Also developed a leak at the front differential. First thought it was the output seal but ended up being the plastic vent cap that screws into the diff.
So far, so good

This plain, Jane GMC has a 6.0 liter engine with a 4.10 rear end. Not good for fuel mileage, usually about 14, but has ranged from 9 with a trailer in the wind to 15 on a flat highway. Warranty work on a jerky transmission, radio failure, rattle in the steering shaft, center console latch, and noisy heater fan. Not much really. Basically satisfied & hoping for a long run.
love this truck

I have not logged too many miles yet (about 1000), but my first impression is this truck meets high quality standards. I have not found anything that needs tightning, fixing, or changing and I have looked under inside and around this vehicle.
Good Truck

Overall am pleased with the standard duty 2500. The truck seems to ride and handle much better than the 2500HD if you do not need the extra capacity.

2004 light duty Sierra 2500 4x4 crew cab w/6-1/2' box. A very comfortable, capable hauler of people and cargo. Rear seat area is huge. Seats are very comfortable. Ride is a little choppy unloaded, but that is to be expected. Smoother ride than GMC 2500 Heavy Duty. Tracks down the road very nicely. (This next comment is not a flame, I'm a truck guy, not a "brand guy") Much better than Ford 250, which tended to wander a bit - that may have been due to the more aggressive off- road tires on the Ford. With a bed cover in place, gas mileage went from 17.5 mpg highway to just over 18 mpg highway. Every bit helps. XM radio is worth every cent. On-Star is invaluable. Great dealer support during sale.
great drive train, rough to ride

The drive train is very good at this point. The ride is a major disappointment. I don't know why they come with such small tires for this size truck.

Dependable truck that takes a beating and asks for more. I've never been easy on my vehicles. This one stands up to the punishment. It's a good looking vehicle. Has more ground clearance than Ford or Dodge without being too tall to go in a parking garage. Build quality and materials/ components used are better than competitors also. I've heard (for example) Ford doesn't put grease fittings on a lot of they're front end parts.

I enjoy driving this truck! So far it stranded me once (due to a clip of some sort coming loose and the computer not knowing enough to send fuel to the engine) and that was at about 7k miles. OnStar answered quickly and got me a tow truck pronto! The dealer easily found the problem and my cost for all this was $0. The Bose system is very enjoyable. Acceleration and power are there when you need them. My 13MPG is lower than I expected, unfortunately.
