2005 Chevrolet TrailBlazer EXT common problems

Owners have filed 1,702 complaints with NHTSA. These are the most-reported areas in a sample of the most recent — and what to check before you buy.

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.
Structure
Inspect for rust, fresh undercoating, mismatched paint, uneven panel gaps and any sign of prior collision or frame repair.
Fuel/propulsion System
Check for fuel or battery warnings, hard starts and stalling. On a hybrid/EV, confirm charging and range behave normally.
Electrical System
Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
Exterior Lighting
Confirm all headlights, brake lights, turn signals and reverse lights work, with no moisture inside the housings.
Visibility
Test wipers, washers, defrosters and all mirrors. Check the windshield for cracks and any camera/sensor for fogging or faults.
