🔥 2 involved a fire 🚑 1 reported injury
🔍 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.
🔍 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.
🔍 Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
🔍 Brakes should feel firm and quiet — no grinding, pulsing or pulling. Check for an ABS light and uneven pad/rotor wear.
🔍 Inspect for rust, fresh undercoating, mismatched paint, uneven panel gaps and any sign of prior collision or frame repair.
🔍 Test cruise control and throttle response, and watch for any hesitation or unintended acceleration.
Pre-purchase checklist
- Match the VIN on the dash, door jamb and title — they must be identical.
- Cold-start the engine; listen for knocks and check for blue or white exhaust smoke.
- Test-drive through all gears at low and highway speed — no slipping, shudder or pulling.
- Confirm every warning light clears at startup (none should stay on).
- Check fluids — oil, coolant, transmission — for level, color and leaks.
- Look underneath for rust, fresh undercoating or signs of collision repair.
- Always get an independent pre-purchase inspection from a trusted mechanic.
