Faults that affect 2022 cars
- Medium severityFrequency: OccasionalChargingCharging faults: on-board charger and interrupted chargingOn the MG4, ZS EV and Marvel R there are owners who see AC charging rejected or interrupted; fiches-auto attributes it to the on-board charger or its software. It is an occasional issue, not a systemic one.
- High severityFrequency: RarePower electronicsHigh-voltage system fault warning and loss of propulsionIsolated cases have been documented of MG4 and ZS EV cars going into limp mode or losing propulsion with high-voltage system warnings. They are scattered testimonies, with no official diagnosis or campaign.
Faults outside the engine in the 2022 MG MG4
- High severityFrequency: OccasionalAirbags and safetyOversensitive driver assistance (sudden braking, lane warning)In an Autopista test, the MG4's adaptive cruise control braked sharply several times for no real reason on detecting cars in adjacent lanes, and the lane keeping and drowsiness warning proved excessively sensitive; fiches-auto.fr records similar complaints from owners.
- High severityFrequency: OccasionalElectronics and infotainmentCentral locking and keyless entry that are unreliable (super-lock)In 2022 the British DVSA recorded a recall of 1,960 MG4s because the car could lock its doors when stopped, with them unable to be opened either from inside or outside; the fix is a software update. fiches-auto.fr adds reports of erratic openings.
- Medium severityFrequency: RareElectrical systemAbnormal 12 V battery drainSeveral owners describe the MG4's 12 V auxiliary battery draining abnormally while the car is parked, which can leave it unable to open the doors or start its on-board systems, according to a French compilation of testimonies.
- Low severityFrequency: OccasionalElectronics and infotainmentCentral screen freezes and restartsIt is the most frequently cited problem among the MG4 owners consulted by fiches-auto.fr: the central screen freezes, restarts by itself or goes black, with temporary loss of the rear camera, navigation or the car's settings.
- Low severityFrequency: OccasionalBodywork and interiorFragile paint and rust in body weldsAmong the 87 reports on fiches-auto.fr, fragile paint is one of the most frequently mentioned complaints about the MG4, with some cases of rust in subframe welds; What Car? also includes the bodywork among the fault areas in its British survey.
- Low severityFrequency: RareClimate controlIneffective climate control or heat pumpThere is the odd documented case of ineffective or inoperative climate control in the MG4, with no cooling or heating, according to a French compilation of testimonies; the source does not distinguish whether it affects versions with conventional air conditioning or with a heat pump more.
