• Official figures from laboratory type-approval tests. VCA says they may not be achieved in real-world driving, and should not be used to rank cars with similar figures.
• Electric cars produce no exhaust CO2; range and miles per kWh are VCA’s official figures.
• A version is one line in VCA’s data (description, gearbox, engine and fuel), counted once however many years it was listed. Matched from VCA’s model names “MG4 EV 2023MY”, “MG 4 Urban”. How we use VCA’s figures.

MG 4 safety recalls

DVSA lists 1 safety recall for the MG 4, launched on 7 January 2023.

A recall applies to cars built on particular dates or with particular VINs, not to every MG 4. The details come from manufacturers through DVSA, which says they may be delayed or incomplete. To check a specific car, use GOV.UK’s vehicle recall check or ask the manufacturer or a dealer. How we match recalls to models.
