Reliability, common problems and owner reviews for the Opel Mokka B 1.2 PureTech (EB2 turbo). Check this before you buy used.
The Mokka B is built on the Stellantis PSA platform, so the petrol is the 1.2 PureTech turbo (EB2 — the same engine as the Corsa F, Peugeot 208/2008 and Citroën C4) — lively and refined, but the engine to be most careful with: the wet timing belt (belt-in-oil) degrades and sheds material that can block the oil pickup and destroy the engine, a notorious, expensive failure with extended warranties and rebuilds, plus oil-dilution and tensioner issues. Later production moved to a chain. Buy a wet-belt car only with documented early belt replacement and obsessive oil changes; otherwise prefer the diesel or a chain-era car.
