💥 1 involved a crash 🚑 4 reported injuries
🔍 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.
🔍 Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
🔍 Drive through every gear: watch for slipping, hard or delayed shifts, and shudder. Check for transmission/driveline leaks and noises.
🔍 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.
🔍 Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
🔍 Steering should be tight and centered — no play, clunks or wandering. Test at low and highway speed; listen for power-steering whine.
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.
