American Brand of SUVs and Trucks. Hummer is an American vehicle brand originally launched as a civilian version of the AM General Humvee military vehicle. The original H1 was produced from 1992 to 2006, with the H2 (based on GMT820 Chevrolet Tahoe/Yukon) and H3 (Colorado/Canyon-based) produced from 2002 to 2010 when GM discontinued the brand. The GMC Hummer EV relaunched the Hummer name in 2021 as a zero-emission electric pickup truck and SUV with extreme capability — 1,000 horsepower, Extract Mode air suspension raising ground clearance to 16 inches, and CrabWalk diagonal driving mode.

For owners of original H1, H2, and H3 Hummers, maintenance involves large displacement GM engines — the H2's 6.0L Vortec V8 and H3's 3.5L inline-5 or 3.7L inline-5. The H2 shares nearly all its drivetrain with the Chevrolet Tahoe and GMC Yukon, meaning parts availability is strong despite Hummer's discontinuation. The H3's 3.5L and 3.7L inline-5 engines are Vortec units shared with GMC Canyon and Chevrolet Colorado; they require 5,000-mile oil changes and have a known cylinder head and valve train design that requires attention on high-mileage examples.

For Hummer owners in Chicago, mobile mechanics provide the most practical service option — H2 and H3 parking in Chicago's urban neighborhoods is challenging given the vehicles' substantial footprint, and mobile service eliminates the problem of finding a capable shop bay. The H2's 4WD system and massive tire clearance make it genuinely capable in Chicago winter conditions, but the high center of gravity requires cautious handling on icy surfaces.
