MG ZS EV I (2019 – 2021)

Reliability score : 8.2/10

The first-generation MG ZS EV (2019-2021) marked the spectacular return of the British marque (now under the aegis of Chinese giant SAIC Motor) to the European market. Positioned as an ultra-competitive 100% electric urban/compact SUV, it democratized access to family electric mobility thanks to an unbeatable price/equipment ratio. Based on the existing petrol ZS platform in Asia and the UK since 2017, it integrates a 44.5 kWh liquid-cooled battery and a 143 hp motor. While it excels in cabin space, comfort, and its 7-year manufacturer's warranty, it suffers from a dated and slow infotainment system, a modest range (263 km WLTP) limiting it to suburban use, and some finish shortcomings. However, the basic mechanical and electrical reliability is very reassuring, with the main complaints fo

✅ Strengths

Unbeatable price/equipment/cabin space ratio on the used market
7-year or 150,000 km manufacturer's warranty (transferable)
Overall reliability of the electric powertrain and high-voltage battery
Generous interior space and boot volume (448 liters)
Smooth driving and suspension comfort

⚠️ Weaknesses

Extremely slow, unergonomic, and bug-prone infotainment system
Limited real-world range (often under 200 km in winter or on the highway)
Fast charging speed (DC) capped at 76 kW (and dropping quickly)
Quality of some interior plastics and imperfect sound insulation at high speeds
Charging flap located in the grille, exposed to impacts and frost

🎯 Verdict

The first-generation MG ZS EV is an extremely rational choice for anyone looking for a family electric SUV on a controlled budget. While it doesn't flatter the ego with its onboard technology (the central screen requires patience) or its highway range, it perfectly fulfills its role as a daily 'commuter', comfortable and spacious. The reliability of the electric drivetrain (supplied by SAIC) is excellent, with serious breakdowns being extremely rare. Inconveniences are generally limited to a capricious 12V battery or multimedia bugs. Buy with confidence for suburban use, prioritizing a model with a clear service history (and thus software updates) to benefit from the remainder of the 7-year warranty.
