💥 1 involved a crash 🚑 2 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.
🔍 Check for fuel or battery warnings, hard starts and stalling. On a hybrid/EV, confirm charging and range behave normally.
🔍 Inspect for rust, fresh undercoating, mismatched paint, uneven panel gaps and any sign of prior collision or frame repair.
🔍 Check tread depth, the DOT age date, and that all four tires match with even wear. Look for bulges or cracks.
🔍 Brakes should feel firm and quiet — no grinding, pulsing or pulling. Check for an ABS light and uneven pad/rotor wear.
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.

Cowl vent grille openings allowed normal environmental debris to accumulate, plug drainage and divert water onto electrical components and potentially result in a fire if not addressed. Some of the debris passes through into the hvac system and cannot be cleaned without dealer removal/repair of the hvac motor, which costs the customer more than $500 in rep…

When coming to a full stop at a red light (or any need to idle at a stop), the car frequently begins to hesitate as if it is about to cut off. I assume it has something to do with the ‘fuel saving feature’ which comes on in the form of a green symbol in the lower left of the odometer display (the engine is still running the AC) . When you start to drive ag…
