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.

I use mine as a strict work truck,; cloth seats, rubber floor mat and auto was only option. Easiest vehicle to drive I have own; very docile and predictable. But GM botched the steering shaft coupler; rattles across rough terrain.
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.
