The Opel Mokka B (sold as the Vauxhall Mokka in the UK) marks a radical departure from its General Motors-era predecessor. Built on the Stellantis CMP (Common Modular Platform), it is significantly lighter, more compact, and introduces the striking 'Opel Vizor' front-end design language. Positioned as a stylish B-segment SUV, it prioritizes design and technology over outright practicality. While the petrol engines (PSA-derived 1.2 PureTech, marketed as 1.2 Turbo by Opel) offer excellent efficiency and punchy performance, they are plagued by the well-documented Stellantis wet timing belt issues. A recent facelift (late 2024 for the 2025 model year) introduced a much-improved 48V mild-hybrid powertrain featuring a timing chain, alongside upgraded infotainment systems.
The Opel Mokka B is a triumph of design but a minefield of reliability if you choose the wrong engine. Avoid the standard 1.2 Turbo (100/130 PS) petrol engines unless you are leasing the car with a full warranty, due to the catastrophic wet timing belt design. If you are buying used, demand absolute proof of meticulous servicing. The 1.5 Diesel is only suitable for high-mileage drivers but carries AdBlue risks. The best choices are the Mokka-e (Electric), which is generally solid despite minor electrical gremlins, or the newly introduced 1.2 Hybrid 48V, which finally ditches the wet belt for a reliable timing chain. Buy the Hybrid or the EV; negotiate heavily or avoid the standard petrols.
