The most-reported problem areas from 395 owner complaints filed with NHTSA — and what to check before you buy.

Exterior Lighting
Confirm all headlights, brake lights, turn signals and reverse lights work, with no moisture inside the housings.
Electrical System
Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
Fuel/propulsion System
Check for fuel or battery warnings, hard starts and stalling. On a hybrid/EV, confirm charging and range behave normally.
Latches/locks/linkages
Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
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.
