Common Issues to Watch For
Based on the 2023 MG 4 SE's fuel type, age, and engine size, these are the most likely problem areas to check.
Battery Degradation
Medium riskAfter 3 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.
Software Updates
Low riskOlder EVs may miss out on manufacturer software updates that improve range and features. Check the infotainment system is up to date.
12V Auxiliary Battery
Low riskEVs still have a standard 12V battery for accessories. These drain faster than in petrol cars and can leave you stranded if flat. Replacement is £100-£200.
Service History
Low riskAlways request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
