MG ZS I (essence) (2017 – 2021)

Reliability score : 7.8/10

MG ZS Generation I (2017-2021) The first-generation MG ZS marked the serious return of the SAIC-owned MG brand to the global mainstream market. Positioned as a budget-friendly B-segment SUV, it undercuts established rivals while offering class-leading interior space and a generous standard equipment list. While the ZS EV (electric) variant garnered the most media attention and a 5-star Euro NCAP rating, the petrol variants (which received a mediocre 3-star Euro NCAP rating in 2017) remain the backbone of its sales in emerging markets, Australia, and parts of Europe. The petrol lineup relies on older, naturally aspirated technology (1.5L) or GM-co-developed small-capacity turbo engines (1.0T, 1.3T). Global Note: The pre-facelift model (2017-2019) suffers from a notoriously laggy infotainmen

✅ Strengths

Exceptional value for money on the used market
Class-leading interior space and boot capacity (448 litres)
Long manufacturer warranty (7 years / 80,000 miles in UK/Aus) often transferable to second owners
Generous standard equipment (Apple CarPlay, parking sensors on most trims)
Comfortable, soft suspension setup suited for poor city roads

⚠️ Weaknesses

Sluggish and noisy petrol engines (especially the 1.5L NA)
Poor 3-star Euro NCAP safety rating for petrol models (lack of active safety tech pre-2020)
Infotainment system on pre-facelift models is notoriously slow, laggy, and prone to crashing
High depreciation rates compared to mainstream European/Japanese rivals
Thin paint quality, highly susceptible to stone chips and scratches
Vague steering and excessive body roll in corners

🎯 Verdict

The first-generation MG ZS petrol is a quintessential 'you get what you pay for' vehicle. It is highly recommended for buyers who prioritize space, equipment, and a long warranty over driving dynamics and brand prestige. Buying Advice: If you are buying a petrol ZS, the 1.5 VTi-Tech is the safest bet for long-term reliability due to its mechanical simplicity, even though it is painfully slow. The 1.0 T-GDI offers a better drive but introduces potential direct-injection and turbo complexities. Crucial Tip: Try to stretch your budget to a 2020+ facelift model. The upgraded interior and vastly improved 10.1-inch infotainment system cure the biggest frustrations of the 2017-2019 models. Always ensure the car has a full main-dealer service history to keep the excellent 7-year warranty intact.
