2004 Hummer H2 common problems

Owners have filed 59 complaints with NHTSA. These are the most-reported areas in a sample of the most recent — and what to check before you buy.

Electrical System
Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
Service Brakes
Brakes should feel firm and quiet — no grinding, pulsing or pulling. Check for an ABS light and uneven pad/rotor wear.
Engine
Listen for knocks or ticking, check for leaks and blue/white exhaust smoke, and make sure it doesn't overheat. No check-engine light should be on.
Electronic Stability Control (esc)
Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
Air Bags
Confirm the airbag light turns on then off at startup — if it stays lit there's a fault (costly, and a safety risk). Check for signs of prior deployment.
Seat Belts
Check that every belt latches, retracts and locks under a sharp tug, and that none are frayed.
