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.
Service Brakes
Brakes should feel firm and quiet — no grinding, pulsing or pulling. Check for an ABS light and uneven pad/rotor wear.
Suspension
Listen for clunks over bumps, check the car sits level, and look for uneven tire wear and worn shocks or struts.
Forward Collision Avoidance
Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
Fuel/propulsion System
Check for fuel or battery warnings, hard starts and stalling. On a hybrid/EV, confirm charging and range behave normally.
