Review of the 2003 GMC Sierra 1500

  • Powerful drivetrains, classic exterior styling and unique options make the Sierra a pickup worth considering, but Fordís new F-150 has it beat when it comes to interior design and overall refinement.

  • Safety
  • Pros

    Roomy extended-cab models, strong V8 engines, innovative features.

  • Cons

    Spotty fit-and-finish concerns, low-grade interior materials.

  • What's New for 2003

    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.

Just like a beautiful woman

Vehicle: 2003 GMC Sierra 1500 4dr Extended Cab SLE 4WD LB (5.3L 8cyl 4A)

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.




Great truck

Vehicle: 2003 GMC Sierra 1500 4dr Extended Cab 4WD SB (4.8L 8cyl 4A)

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.

Vehicle: 2003 GMC Sierra 1500 4dr Extended Cab SLE 4WD LB (5.3L 8cyl 4A)

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.




Best vehicle i have ever

Vehicle: 2003 GMC Sierra 1500 4dr Extended Cab SLE Rwd SB (4.8L 8cyl 4A)

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.




So far so good

Vehicle: 2003 GMC Sierra 1500 4dr Extended Cab SLE 4WD SB (4.8L 8cyl 4A)

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.




Best truck on the market

Vehicle: 2003 GMC Sierra 1500 2dr Regular Cab Rwd SB (4.3L 6cyl 5M)

Original owner. 130k miles. RELIABILITY-I've 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 Ford's, but this pickup (w/3.42 rear end) sure feels stronger than my brother's (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 GM's powertrain sold me. None of the tranny problems typical of Hondas, better engines than Toyota.
