Medium riskAfter 5 years, expect some battery capacity loss. Check the battery health report for state of health (SoH). Below 80% significantly reduces range.
Charging Port
Medium riskCharging connectors and ports can develop issues from regular use. Check both AC and DC charging work correctly before purchasing.
