Overview & Reviews
The Sierra gets a revised look this year that includes a new front fascia, revised side moldings and an additional wheel design. Top-of-the-line models get power-folding heated mirrors with puddle lamps and turn signal indicators. Inside, the Sierra now offers a Bose stereo system and XM Satellite Radio. The instrument panel and center console have been redesigned, and GMC has added new seats, a more comprehensive driver information center, optional satellite steering wheel controls and a dual-zone climate control system. For increased safety, Sierras now feature a standard front-passenger-sensing system and dual-stage airbags. All 4.3-liter V6-equipped Sierras and California-emission V8s are now ULEV certified, while electronic throttle control is now standard on all V8 engines. Finally, the Autotrac four-wheel-drive system has been modified for less intrusiveness at low speeds, and the brake system received upgrades that provide better pedal feel and improved overall performance.
- Roomy extended-cab models, strong V8 engines, innovative features.
- Spotty fit-and-finish concerns, low-grade interior materials.

Great Truck - 2003 GMC Sierra 1500
By CJB - December 15 - 12:06 amI 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.

Top Truck - 2003 GMC Sierra 1500
By Chazz - November 19 - 8:46 amWhen 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.

Love it but diappointed - 2003 GMC Sierra 1500
By Truck4 - October 28 - 2:00 amThis 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 Ive sat in. A friend recently purchased a comparable Ford model. After riding in my truck, hes 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 90s 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.

Too many small problems - 2003 GMC Sierra 1500
By tedmc - October 10 - 2:30 pmOverall, a nice truck, but too many small problems that are now adding up. So far, Ive had the steering shaft replaced 3-4 times, the passenger back window replaced, the heated seats on the drivers side replaced, and now the instrument cluster has gone haywire. Oh yeah, Ive 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 wont buy GM again if there are other options out there. Too bad.

By Kelvin Bowman - August 29 - 8:30 amThe comfort of the ride is outstanding. Able to pull trailers with ease. Not bad gas mileage for size of vehicle.

Super Truck - 2003 GMC Sierra 1500
By Robert - July 11 - 9:00 amI 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 dont see myself ever replacing my truck it has been a good ride so far.

You cant go wrong - 2003 GMC Sierra 1500
By F. Gibbons - May 22 - 2:50 pmPurchased 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.

Best Vehicle I have ever Owned - 2003 GMC Sierra 1500
By Tony - November 25 - 5:16 amBought 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.

Good Truck - 2003 GMC Sierra 1500
By Geoff2 - September 9 - 2:00 amI traded in a 2002 Z71 silverado for this 2003 Z71 Sierra(new). I was suprised to find the same annoying rattles that I had fixed on my 2002. The windshield rattles, which is because of the exterior window trim. The doors sqeaked, which is because GM is to cheap to oil their doors at the fatory. Other than the annoying issues that took one trip to the dealership I couldnt ask for a better looking,riding and performing truck. Hopefully GM doesnt decide to cheapen it up down the road!

Best Truck on the market - 2003 GMC Sierra 1500
By Russell - January 30 - 1:30 pmOriginal owner. 130k miles. RELIABILITY-Ive only had 2 problems, and 1 (speedometer) was a recall. The catalytic converter went out at 115k, but other than that, no rattles, no squeaks, not even a brake job. Overall reliability is good, better than my Toyota Matrix. DRIVETRAIN-GM says this V6 has less HP than Fords, but this pickup (w/3.42 rear end) sure feels stronger than my brothers (w/3.55). No oil leaks at 130k, no slips in the tranny. INTERIOR-I like it, but most auto critics say it looks cheap. Seats are plush and ride is comfy. Overall reliability may belong to Honda/Toyota, but GMs powertrain sold me. None of the tranny problems typical of Hondas, better engines than Toyota.
