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.

Poor Ride with wheel vibration - 2003 GMC Sierra 1500
By Timmcp - October 30 - 10:00 amAfter about one week of driving, the truck began to vibrate excessivly especially on concrete freeways. Took it in 4 times, each time the wheels were way out of balance. They cant figure it out. They think that maybe the tires are moving on the rim. These are Bridgestones on aluminum wheels. It turns out that you may get Bridgestones or Firestones(same ones recalled by Ford) depending on what they have laying around at GM. It is made worse by a poor suspension design that does not perform well at highway speeds. At this point the tires are still out of balance and the dealer doesnt know what to do or what is happening.

my truck - 2003 GMC Sierra 1500
By wright - August 25 - 10:00 amThe 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.

2003 GMC 4WD Pickup - 2003 GMC Sierra 1500
By Walt Moore - May 29 - 7:36 pmI bought this new and its 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 wont really know for another 15 years, which is about how long I plan to keep it.

Best GMC Yet ! There is no competition! - 2003 GMC Sierra 1500
By Towers - March 30 - 10:00 amI 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!

Couldnt ask for anything more. - 2003 GMC Sierra 1500
By rustysmith - December 11 - 5:53 am6 years later, Im still happy with my purchase. Its been a great truck with no worries. The only problem Ive had is not getting the speedometer fixed before the recall ran out. My own fault. Other than that, only oil changes for over 120k miles. Reliability on these trucks is second-to-none. I have three friends with the same body style (one 04 and two 05s) and all have over 100k miles w/only 3 problems. My speedometer went out @ 105k. On the 05, his alternator went out @ 134k and his tranny went @ 166k. Using the gold standard of reliability, he has an 01 Camry. The starter went @ 150k and the tranny @ 160k. GM seems to be catching up to the Japanese automakers. Great job.

Runs real good.. but still cautious. - 2003 GMC Sierra 1500
By SDW - November 10 - 10:00 amIm a Chevy/GMC man- have been for ten years; bought my new GMC 1500 Sierra SLE at the end of February, Ive 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 dont know what the growling is in the 4wd, but other than that the trucks been fine.

Pleased - 2003 GMC Sierra 1500
By Pop-pop - October 15 - 2:00 amI 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.

Screw the competiton BUY THIS TRUCK - 2003 GMC Sierra 1500
By Z71-Stud - September 22 - 2:00 amOut of all the trucks I have ever owned this has to be the best! From the well thoughtout interior, powerful vortec engine, and classic styling I really cant ask for too much more. Well then again; Hey GM, how about a big block option!

Great Truck - 2003 GMC Sierra 1500
By Jason 95834 - August 28 - 2:00 amI have taken all the makes for this type of truck for a test drive, and this truck was the one. The GMC has the best handeling/comfort, good power and excellent seats and interior(did not look tastless or cheasy).Hardly any wind noise and no annoying vibrations. Build quality I am most impressed with. Someone in a Mustang t-boned the truck on the drivers side and caused 3K worth of damage. Totaled the Mustang. Most importantly no one was injured. I got the truck back after the body shop fixed and cleaned it up.Hats off to the guys at the body shop and to the GMC division for building a great truck keeping my wife safe.
