MG ZS EV I facelift (2021 – 2024)

Reliability score : 7.8/10

The first-generation MG ZS EV benefited from a significant facelift (Phase 2) at the end of 2021, marking a clear move upmarket. Aesthetically, it abandons the fake thermal grille for a solid front fascia, asserting its electric identity. Technically, the evolution is major: the old 44.5 kWh battery is replaced by two new offerings. A 'Standard Range' version with a 50.3 kWh LFP (Lithium Iron Phosphate) battery, and a 'Long Range' version with a 70 kWh NMC (Nickel Manganese Cobalt) battery. The iSMART infotainment system makes its appearance, as does the V2L (Vehicle-to-Load) function. Although primarily targeting the electric market in Western Europe, the ZS remains available with internal combustion engines (naturally aspirated and turbocharged) in many markets (UK, Eastern Europe, Asia,

✅ Strengths

Unbeatable price/equipment/range ratio in the EV market
Reassuring manufacturer warranty (7 years or 150,000 km)
Generous interior space and boot volume (448 liters) for the category
LFP chemistry on the Standard Range version, excellent for longevity
Presence of the very practical V2L (Vehicle-to-Load) function
Clear improvement in soundproofing and finish compared to Phase 1

⚠️ Weaknesses

iSMART infotainment system often slow and buggy
Disappointing fast charging (DC) curve (rapid power drop after 50%)
Front-wheel traction could be improved (frequent wheelspin in the rain with electric torque)
Dealership network still uneven depending on regions (parts delays sometimes long)
Slightly high electricity consumption on the highway (aerodynamics could be improved)
Recurring 12V battery discharge problems

🎯 Verdict

The facelifted MG ZS EV (2021-2024) is an extremely rational choice for anyone looking for an affordable family electric SUV. The hardware reliability (motor, battery) is very good, supported by a 7-year warranty that covers major risks. The chosen battery chemistries (LFP for city/suburban, NMC for long trips) are relevant. However, the user experience is often marred by a fickle software (iSMART) and minor electronic bugs (12V battery, charging communication). It is a highly recommended purchase as a recent used car, provided that all software updates have been applied and that a competent MG dealership for after-sales service is nearby.
