Known faults on the 2018 Ford B-Max petrol

Reported by owners, mechanics and buying guides for this model and age. Check which engine the car has, as some apply to one engine only.

• Timing belt that runs in oil (1.0 EcoBoost)

  1.0 petrol (EcoBoost and non-turbo)

  Ford’s 1.0 three-cylinder petrol uses a timing belt that runs in the engine oil on most cars. If oil changes are late or the wrong oil is used, the belt breaks down and sheds rubber that blocks the oil supply, which can wreck the engine. Some later cars have a timing chain instead: a Ford dealer can tell you from the VIN. Ford’s change interval is 10 years or 150,000 miles, and the belt isn’t covered by warranty.

  At the viewing: Ask for a full service history with the right oil, and when the belt was changed. An oil-pressure warning light, a rattle or a rough idle are warning signs.
