2019 GMC sierra 3500 common problems

The most-reported problem areas across all 12 owner complaints filed with NHTSA — and what to check before you buy.

Service Brakes
Brakes should feel firm and quiet — no grinding, pulsing or pulling. Check for an ABS light and uneven pad/rotor wear.
Equipment
Test all accessories — sunroof, climate, seats, electronics — for proper operation.
Electrical System
Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
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.
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.
Fuel/propulsion System
Check for fuel or battery warnings, hard starts and stalling. On a hybrid/EV, confirm charging and range behave normally.
