Common Problems
MG 4 EV Engine Problems - What It Costs to Fix & When Replacement Makes Sense
The MG 4 EV's electric powertrain is generally reliable, but MCU failures, motor bearing wear, and charging system faults can drive replacement enquiries. Every rebuilt motor supplied through EngineMarket includes upgraded internal components designed to address original failure points - plus a minimum 12-month unlimited mileage warranty.

Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| MCU Software Reset/Reflash - Diagnostic reset of motor control software | £450 - £850 | £280 - £520 | OBD diagnostic session, software update, system recalibration | Temporary fix; suitable if fault is software-only, not hardware |
| MCU Replacement Only - Swap control unit, retain existing motor | £1,800 - £3,200 | £1,200 - £2,100 | Remove faulty MCU, install refurbished/rebuilt unit, programming | Viable if motor windings and bearings are confirmed healthy |
| Full Replacement - Rebuilt Motor + MCU - Complete drive unit swap | £3,500 - £6,200 | £2,800 - £4,500 | Supply & fit rebuilt motor assembly with integrated MCU, bench-tested | Best value for high-mileage cars; addresses root cause comprehensively |
Our recommendation
If your MG 4 EV is under the 7-year/80k-mile manufacturer warranty, contact MG first. For out-of-warranty vehicles over 50k miles, a full rebuilt motor often offers better long-term value than MCU-only repairs.
