I got this truck used with 80000. It had a bad intake gasket and got replaced. Engine has not given me any issues since. z71 4x4 is pretty dang nice, its hard to get this this thing stuck in the mud. Issue with the motor in the transfer case... but never stopped working (says service yada yada. been checked. not a big issue). basic maintenance and think I can give this vehicle to my kids (not soon either). GMC seems like a good truck with some quirks, but solid and runs when you need it. The 5.3 has some passing power, and tows like a champ. If you like your girls a little high maintenance, go on and get it. If not, then buy an old truck and forget about all the gadgets. good luck.

Bought new in late 2002 truck has been average for comfort and mileage is good. Reliability is not good to many small issue my truck only has 60k and have replaced both front wheel bearings, replaced two power window motors, had to replace sensor for ABS brakes, steering gear box and now the cluster is going bad. GM know the cluster unit is an issue but refused to help on the repair cost. I think I am going to look at the Toyota Tundra for my next truck. GM just need to have a better warranty on the little things that are always going bad on their vechiles.

I bought the truck new in 2003.I needed something for the snow and thought I would try a GMC for once.There have been no problems with the truck until the 4WD module went out at 55k miles.The truck seems to dance around in the rear end in the snow abit.havent had any problems to speak of until 85k miles when the left front hub bearing went out. Tires lasted until 68k miles and still have the original battery in it.The front/rear brakes still have 50% left and should be good until 150k miles.The interior is still solid and everything still works like the day I bought it.

I have just turned 70k in my 2003 Denali and its been a solid truck. Regular maintenance and I am told by the lube guy that there is a very small fluid leak from the intake. This is common in Vortec engines according too him. I guess overall I have been very impressed I just hope they have used better materials for the interior of newer models. I don't see myself ever replacing my truck it has been a good ride so far.

My 03 Serria Denali is a beautiful truck, but i have had one problem after another. New power steering pump, master cylnder, fuel pump, alternator, 2 starters!, new steering column, lower intake, new front end bearings, and emissions control valve. Now my left blinker turns on my hazards! I give up....give me a new truck!

The automatic dual climate control is nice, but in the auto mode...you cant seem to keep the interior as cool as you might want. The silent recall concerning the rust behind the front bumper was something I was definately unhappy about. I had to learn about it on the internet, and when I took it to two different dealers, I got a bit of the runaround. Both claimed that I had the only truck that had been brought in for this problem.

Bought truck new in 03,I have over 140K and have not had to spend $1 on repairs. Replace fluids and do proper maintenance and it runs as good as the day I bought it.Would like to buy a new truck but cannot justify replacing it as it is so reliable. I drive a lot of highway miles and get almost 19 MPG if I keep it around 70 MPH.

It has had too many problems for a truck that costs as much as it does, with only 6000miles. First the tailgate had to be replaced b/c it had holes in it, not sure from what. Next the mirror display(comp.& temp.)went out, had to be replaced, then I found that the passenger side a/c gets stuck on hot when you turn it all the way up, still working on it, now the front axle housing is leaking oil. This truck has never been in the mud, or ragged. What a waste of my time and money, I will never buy again or recomend a GMC product to anyone.

Purchased this truck with 48K and am very surprised of the quality of this truck. Being five years old I expected the suspension to maybe a tad loose or at the very least expected to hear cabin rattles and squeaks. Nothing; feels like a brand new truck. I have the SLT with the Bose and heated leather buckets. You never want to get out of it! Looked at all the other manufacturers and now know without question, I made the right choice.

This is poor quality truck. In five years I have had five repairs and one recall. My repairs have included a cracked transmission case, bad steering mid-shaft, bad seatbelt, bad water pump, and bad wiper switch. In addition, I am currently losing lights in my dash and have lost most of my fan. GM likes to advertise this as 'professional grade.' However, no professional in his right mind should buy this truck. Please save yourself and buy something else.

Can't say enought about this truck. I moved up from a 4cyl Toyota because I needed to be able to tow a ski boat. With a full bed of coolers and ski supplies and 6 passengers plus the boat, I can't even tell there's a boat back there. I drive 60 highway miles a day to work and have yet to find anything that rides as smooth. I had an issue with a low pressure sensor on the A/C but that was under warranty and fixed several years ago. Other than 3 sets of tires and a bunch of oil and filter changes I have had no reason to work on the truck It's fun to drive and has never let me down. Even in the Georgia heat the A/C will freeze you out.

When I first purchased this truck I thought it was the smothest riding and best handling 4x4 I had ever driven. (Wife has purchased a Yukon 4x4 and it is even smoother riding) It has spent a good deal of time off road. I do not get rough or overly abusive, mostly steep hills, sand, mud under 6-8 inches and a little rock crawling. If yours does not have the locking rear differential it is worth the money. I am sure it has saved me more in tow services than it costs to have installed. I have not had any serious mechanical failures, I did have a u- joint start chirping on me after a week in the hills of western South Dakota. The truck has about 50,000 miles on it and gets serviced regularly.

Traded in a 2002 Silverado for this 2003 Sierra. Got the color and options that I really wanted, plus improved performance with 2003 trucks. Build quality was poor with lots of visits to dealer for minor warranty repairs, but now the truck has been terrific. Looking now to downsize for a smaller truckk with almost same towing for fish/ski boat. Fuel mileage has been 21-23 with 5.3L and 3.42 rear, synthetic oil, tires pumped up to 44 lbs always.

I have owned a Ford F150 extended cab and Z71. I was a little leery of this truck because everybody complained about gas mileage. My Z got about 13 and my F150 got about 14. I'm getting a solid 13.7 so big whoop. I love this truck performance and comfort. My wife drives a Yukon and gets 17. For the 3 difference I'd rather have the quadrasteer and the comfort. I've put 30,000 on this truck and about to turn 50,000 (bought it used). With GM droping the quadrasteer, I plan on keeping it for some time. The big chrome grille let them know you're comin' and the 6.0 let's them know you gone!

Overall, a nice truck, but too many small problems that are now adding up. So far, I've had the steering shaft replaced 3-4 times, the passenger back window replaced, the heated seats on the driver's side replaced, and now the instrument cluster has gone haywire. Oh yeah, I've been complaining about the awful noise the front end makes when the 4WD is engaged, but the dealership (not where I bought it) says that it is normal. Are you kidding me? I still like my truck as it rides and drives great, but I sold a 13 year old Toyota when I bought this one that was a better truck. I probably won't buy GM again if there are other options out there. Too bad.

Overall, an excellent truck. Very quiet and plush on long trips. Excellent truck-like ergonomics, unlike the car- like feel and look of other manufacturers. Great audio (Bose) and Automatic climate controls. My wife and I share time behind the wheel so the seat and mirror memory is great to have. Very solid build quality, which translates into a quite, squeak (silicon lube on the weather striping) and rattle free ride. Front suspension is on the soft side in comparison to the rear. Only evident at slow speed at "bumps" perpendicular to the direction of travel, otherwise a very nice balance.

I own a 1993 GMC 2 door SLE and it has performed well over the past 12 years. It's dependable and rides good. This is why I bought another GMC. I find the 2003 to be just as well built and dependable. The 5.3 engine is a good combination of power and smoothness I want in a vehicle, and my mileage runs around 17 mpg. Of course this drops significantly if I jump on it , or drive in the 70/80/mph range.

I can not be happier with my Sierra. I needed a truck that would tow our 17 foot ski boat and what I got was much better. I traded in a beautiful 1993 Toyota 2.4L pick-up that had 253,000 on her and was still going strong. I hated to do it but I had to have something that would tow a ski boat. I will admit that I looked at other trucks including the Tundra but nothing came close to the comfort of the Sierra. I drive 72 miles round trip in Atlanta traffic daily and this truck is more comfortable than any car. After I replaced the factory GoodYear tires with Firestone's, I had no trouble on wet roads and the ride is whisper quiet. No problems with the truck or repairs needed.

This is the worst vehicle I have ever owned. It has 8000 miles and is always in the shop. It rattles (has been down 1 dirt road for 3 miles), master brake cylinder went out, new front brakes, passenger p/w doesnt work properly (3X to dealer and still not fixed). The rear axle seals have now started leaking. Will never buy another U.S. built auto.

I bought this truck new and have enjoyed over 3 1/2 years of trouble free utility. I've hauled, towed, 4- wheeled, pulled, and just plain driven this truck to great delight and it has met or exceeded expectations all around. Mileage is better than most others trucks averaging 17-18 MPG even with 5.3L, 4WD, SLT luxury package, hard tonneau, running boards, Z71 off- road pkg, and more. Going GMC gives a hiher level of luxury and customer care than you get from Chevrolet. The seat and mirror memory is very useful for getting kids in and out of the back seat. I use the exit position button to bring seat forward enough so they can enter and exit the back easily.

I bought this new and it's generally been great. The windshield wiper control module burned out but that has been the only unscheduled service in 37,000 miles. So far I really like this truck and would buy it again, but I won't really know for another 15 years, which is about how long I plan to keep it.

I couldn't ask for better handling, a better ride, or more power. This vehicle blows the competition away. Quadrasteer makes parking & curvy road handling a breeze, sticks to the road like it's mounted on rails. Interior quality is the best I've found anywhere, the heated leather seats moulds to your body for the ultimate seating comfort. Onstar is a must for safety & convenience. XM satellite radio is better than having a hundred CD's, also the Bose sound system quality is second to none. Select ride smoothes out the bumps in the road lmost as if they didn't exist.

My husband always liked Fords. I talked him into test driving a GMC truck, his experience went well. We were both impressed with the way it handled. I have two babys and we feel we have plenty of room and and a good truck. Were excited. Not to mention we looked at a dozen Fords and we found them to be bubbley and tacky. When we saw the GMC on the Ford lot it was the only one and it was an easy decisionafter seeing.

I bought this truck about a year ago. It was previously owned and I was the second owner. I shopped around looking at all of the "big three" offerings, I even checked out the Tundra and new Titan. I drove all of them. The Dodge was fastest (Hemi Powered) The Nissan Seemed to be the most Techie, Ya know gadgets and such. But the best overall was this GMC, Towing power is top shelf even with the baby 4.8 ltr. I still tow nearly 7000 lbs and it's rated for even higher, not too shabby for a 1/2 ton, If you need to tow more, then obviously you'd be 3/4 ton shopping. But all things considered, The GMC has the all around best value, Mabye not the best in all areas, but certainly superior in most.

I have allways been a GM man, and this truck doesnt disapoint. The heated leather captains seats with two person memory are very comfortable. The steering wheel controls for the Bose stereo are great. Some interior wind noise though, and the suspention is very jumpy on the concrete highways. It is in the shop as I write this having the tranny pulled to find out why it started shifting hard from first to second gear at 15900 miles.

I'm a Chevy/GMC man- have been for ten years; bought my new GMC 1500 Sierra SLE at the end of February, I've enjoyed my truck for months until lately when the quadcab doors started to rattle and my 4wd started to growl. GMC has tried to adjust the doors with no luck and they don't know what the growling is in the 4wd, but other than that the trucks been fine.

This truck has the potential of being everything I want it a truck. It offers a very smooth ride and the leather seats are some of the most comfortable I've sat in. A friend recently purchased a comparable Ford model. After riding in my truck, he's quick to point out the superior ride and comfort of the GMC. Disappointment: I recently scheduled my 2nd service visit because the outside temp gauge constantly reads in the 90's if the temp is above 38 degrees. There are rattles in the dash. This is the 4th GM truck I have owned and this is the least smooth transmission of any of them.

Great truck, only 1 issue. With a little over a thousand miles, sounded like loose sheet metal under the truck. Ended up going back to the dealer 6 times before I went to another dealer. Found out it was the A/C compressor. Mechanic stated that it would build up too much pressure. Thank goodness I didn't put it off. Over $2500 in parts & labor. Not a single problem since. For such a big truck, get wonderful gas mileage. Only one thing I would change... get better viewing side mirrors. Lots of blind spots with the OEM mirrors.

I have owned ford, Nissan, and GMC. My last GMC (2001) was a great truck (SLE ext cab 4x4), but it needed a larger engine and a leather interior. The 2003 was what I was hoping for. Plenty of power, great ride, creature comforts, and can still haul two yards of topsoil. I can look good taking my wife out to dinner and still get the rugged use of a truck!

In January I bought a 2003 GMC Sierra 1500 SLE with the trailering package and the Z71 off-road package. The truck is quite as a church mouse on the inside and runs beautifully. The ride is firm, like a truck, but not so stiff that you have to visit your dentist and have your fillings put back in weekly. Visability is very good and the inside is extremely comfortable (including the back seat). Transmission shift isn't always smooth as GM silk and there is some growl from the front end in 4WD... time will tell if these are normal or not.

The truck has incredible performance and manuvers like a car. Sometimes we get 26 miles to gallon.

I am pleased with this vehicle. Roomy and easy to get in and out of. Plenty of "inside" storage space (rear seats fold down for a huge platform). Plenty of power.

This is the best truck I have ever owned. This is my first Full Size, but my dad has a silverado. My GMC drives just a little bit better,is a little bit quiter, and the exterior styling is the classiest out of all the trucks in the market. Nobody could talk me out of this truck and into anything else. Eventhough the 2004 Ford interior has a good design, you still couldn't pay me enough to own a FORD. The editor that rated the Sierra lost there mind, it should be alot higher than the low 8's. The only thing I regret is not getting the Z71 pkg.

This is a great truck! The ride is smooth and comfortable with great pick- up. My average fuel mileage is around 15 mpg...not real great. Turning radius is wide (watch out in those parking lots). Very nice interior with comfortable seats. Controls are easy to reach and intuitive.

What a Ride

Vehicle weight makes for a comfortable ride. Handles the interstate like a luxury car. The Quadrasteer feature makes moving around the city a breeze. Parallel parking and parking garages with appropriate height clearance are easy to handle. The Denali has good acceleration. Does not get blown around when passing the Big Rigs. Don't expect better than 14 miles per gallon, about 13 mpg at 80 mph. Once you've driven the Denali you'll never want another full-size pick-up without Quadrasteer.

I have the quad door, with the 5.3 engine, and I love it. The Bose stereo rocks, it's a nice looking rig, pulls my 21' boat with ease. I'm 44 years old, and this is the finest truck I've ever owned.

Bought used for 10,500. Low miles 56k. My first real truck. I didn't want to afford a Tundra so this fell in my exact range of price. Drives like a truck and runs like a truck. Its been strong for the couple months of ownership. The seatbelt squeked but some wd-40 after taking off the plastic clip cleaned it right up. BEWARE of installing aftermarket cd players in here. I had to pay 120 dollars for a wire harness do my air bags and door chime worked! The truck is roomy and fits side and rear passengers very well. The spare tire holder under the truck won't work but hey, for the price could not beat it. Looking forward to 4wd this winter and owning a nice big truck.
