Vauxhall Mokka I (J13) (2012 – 2016)

Reliability score : 6.8/10

The first-generation Vauxhall Mokka (J13) (sold under the Opel brand in continental Europe, Buick Encore in North America/China, and cousin to the Chevrolet Trax) is one of the pioneers of the urban SUV segment (B-SUV). Based on the GM Gamma II platform, it stands out with its compact yet stocky dimensions, offering a high driving position and the availability of all-wheel drive (AWD), which is rare in this category. This sheet focuses on phase 1 (2012-2016), before its facelift where it was renamed Mokka X. Well-built and safe, it suffers from a high weight that penalizes performance and fuel consumption, particularly on the petrol engines.

✅ Strengths

High driving position and seat ergonomics (AGR certified as an option)
Availability of a true all-wheel drive (AWD) transmission on a small SUV
Robust and well-assembled interior finish for its time
Generous technological equipment (230V sockets, AFL+ bi-xenon headlights)
Decent soundproofing on petrol versions

⚠️ Weaknesses

Excessive weight (often > 1400 kg) penalizing dynamics and fuel consumption
1.4 Turbo engine prone to leaks (coolant, oil) and the PCV valve issue
1.7 CDTI diesel is very noisy and vibrates
Modest trunk volume (356 liters) for its size
Center console ergonomics (too many buttons before the facelift)

🎯 Verdict

The first-generation Vauxhall/Opel Mokka is a solid, safe, and well-equipped small SUV, but its high weight limits its agility. In petrol, the 1.4 Turbo 140 hp is the most logical choice, provided you are vigilant about the condition of the cooling system and verify that the valve cover (PCV valve) has been replaced in case of whistling. The naturally aspirated 1.6 is reliable but anemic. In diesel, prefer the old 1.7 CDTI (noisy but indestructible) over the newer 1.6 CDTI, whose gearbox-side timing chain is a real financial sword of Damocles.
