Hummer size demands expert service. Quality Hummer repair and maintenance. We service all Hummer models—handling everything from routine oil changes and brake service to timing belt replacement, clutch repairs, and engine diagnostics. Trust your Hummer to a shop that understands what makes these vehicles exceptional.
Hummer H1, H2, and H3 are serious off-road vehicles built on GM truck platforms. We understand their robust drivetrains, transfer cases, and the specific demands that come with off-road use in Utah.
Hummer differentials, transfer cases, and engines require specific fluid specifications — especially for vehicles used off-road. We use the correct specs for how your Hummer is actually driven.
Hummers need serious shops. We handle drivetrain, suspension, and engine work that requires proper equipment, experience, and patience.
We tell you exactly what we found. Hummer ownership involves real maintenance costs — we're honest about what's needed and what it'll cost.
These are some of the Hummer vehicles we work on most often at our South Salt Lake shop. We service all Hummer models — if yours isn't listed, that just means we don't see it every day.

These are the most frequent Hummer problems we diagnose and repair at our South Salt Lake shop. Every job starts with a thorough diagnosis so you know exactly what's going on before any work begins.
The Hummer H2 uses the GM 6.0L/6.2L V8 that shares the exhaust manifold bolt breakage issue with Silverado and Sierra. Extraction requires skill to avoid head damage.
The Hummer H3 3.5L and 3.7L inline-5 engines develop cylinder head cracks causing coolant loss and overheating. We replace heads with updated castings.
Hummer 4WD systems work harder than most due to vehicle weight. Transfer case and differential fluid changes are critical maintenance items.
Utah's temperature swings, mountain roads, and high altitude put unique demands on your vehicle. Here's what we've learned from years of servicing Hummers in the Salt Lake Valley.
Hummer H2 shares the GM full-size truck platform. All Silverado/Sierra maintenance recommendations apply. Change oil every 5,000 miles with Dexos-approved synthetic.
Hummer H3 coolant should be inspected at every oil change for signs of cylinder head cracking. Early detection prevents expensive engine damage.
Hummer vehicles are heavy—brakes wear significantly faster than lighter vehicles. Inspect pads every 15,000 miles and expect replacement every 25,000-35,000 miles.
Yes. The H2 is built on the GM 2500 truck platform with a Vortec V8. We service GM trucks daily and the H2 is mechanically identical. Same engine, same transmission, same transfer case. Our GM expertise applies directly.
The H3's inline-5 engine has a known cylinder head cracking issue that affects reliability. The drivetrain (transfer case, differentials) is robust if fluids are maintained. With head gasket monitoring and regular 4WD service, they can be kept on the road reliably.
Hummers are heavy vehicles with large engines—poor fuel economy is inherent to the design. However, we can ensure your engine is running at peak efficiency through tune-ups, air filter replacement, fuel system cleaning, and ensuring no exhaust restrictions. Proper tire pressure also matters significantly on a vehicle this heavy.
Our shop in South Salt Lake is centrally located in the valley — most customers are within 15 minutes. We service Hummer drivers from throughout the greater Salt Lake area.
