MG4 EV - Reliability and safety

Following Euro NCAP’s crash test assessment, the MG4 EV achieved the maximum five-star safety rating. While that is one star ahead of the Renault 5, that rival was tested under the more stringent 2023 testing standard, whereas the MG4 was measured against standards set in 2020, making comparisons difficult. 

All versions of the MG4 feature six airbags, active emergency braking with pedestrian and bicycle detection, lane-keep assist with a departure warning function, adaptive cruise control and a driver attention alert system. Upgrading to the top-spec Trophy Long Range adds blind-spot detection, lane-change assist and rear cross-traffic alert, which warns of vehicles approaching from either side as you’re reversing.

The MG4 is too new to have appeared in our Driver Power owner satisfaction survey, but MG will want to improve on its showing in the manufacturer ratings because the brand finished in last position in a 32-strong list. Renault did slightly better, although it too could improve in this area because its 28th place finish out of 32 is nothing to write home about either.

Warranty

MG offers a reassuring seven-year/80,000-mile warranty for all of its models and includes the battery pack (which guarantees repairs or replacement if the capacity drops below 70 per cent during the warranty period), which is almost on par with Kia’s seven-year/100,000-mile policy. This extended coverage might be enough for buyers to consider choosing the MG4 over other brands, particularly when compared with Volkswagen’s three-year/60,000-mile warranty.

Servicing

All versions of MG4 need servicing once a year or every 15,000 miles, whichever comes first. MG Service Plans offer flexible options to help manage scheduled maintenance and also allow you to set your own mileage limits.
