These are issues documented for the MG ZS EV in general - things to check for, not a diagnosis of any particular car. Whether a specific car has one depends on its age, mileage, service history and how it was used.

HV Battery Main-Fuse Failure (Dealer Software Fix, Not a Formal Recall)
High-Voltage Electrical / Powertrain Shutdown (HV battery fuse); Charging System (onboard charger, DC rapid-charge communication); Battery Management System (BMS faults, cell-voltage imbalance) · severity: The HV battery fuse fault is genuinely safety-relevant per owner-forum description - a real, disclosed total loss of drive power combined with loss of power steering and brake assistance simultaneously is a serious driving-safety event regardless of its formal recall status. Charging-system and BMS faults are real but lower-severity - inconvenience/range-availability issues rather than an in-motion safety event in the sources checked. · confidence: 33/100 · 4 cited sources

Symptoms to watch for
HV battery fuse fault (real, owner-documented, addressed via dealer software update): total, simultaneous loss of drive power, power steering assistance, and brake assistance - per owner-forum accounts, this can occur without reliable prior warning, making a direct dealer software-update check more useful than watching for a symptom
Charging-system faults (real, not recall-covered): onboard AC charger failing to complete a charge or throwing an error requiring dealer intervention; DC rapid-charge sessions occasionally failing to communicate correctly with a public charging station
BMS/battery faults (real, not recall-covered): stuck or incorrect state-of-charge readings, a 'vehicle control system fault: HV battery shut off' warning reported independently across multiple owner-forum threads, and reduced DC charging speed reported on some 2019-2020-built cars (originally rated 75kW, reported by some owners as capped lower)
General reliability pattern (real, dated UK survey data): a real, low 2024 What Car? reliability score (69.3%) driven, per that survey's own stated basis, primarily by electrical/software issues rather than mechanical faults - improving to a real 88.9% in the 2025 survey
What To Check
The HV battery fuse fault is NOT reliably test-drive-detectable - per owner-forum description it can occur without reliable prior warning, so a clean test drive does not rule it out; a service-history/software-campaign-status check is the only reliable method identified in this pass. Charging-system and BMS faults ARE partially checkable during ownership evaluation (a full charge cycle, watching for warning messages) but may not manifest during a single short test drive, so a longer evaluation period or direct diagnostic-system check is materially more reliable.
