Known faults on the 2019 Ford S-Max

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.

• Oil pump belt that runs in oil (2.0 EcoBlue diesel)

  2.0 EcoBlue diesel (most Ford 2.0 diesels from about 2018)

  The 2.0 EcoBlue diesel drives its oil pump with a belt that runs in the engine oil. As it wears it can shed rubber and cut oil pressure, which can wreck the engine. Ford has shortened the change interval on the Transit to 6 years or 100,000 miles.

  At the viewing: Ask when the oil pump belt was last changed, and watch for an oil-pressure warning light.

• May have a timing belt that runs in oil (1.5 EcoBoost)

  1.5 EcoBoost petrol

  Ford used both wet timing belts and timing chains on its 1.5 EcoBoost petrol. A wet belt can break down if oil changes are late, starving the engine of oil. A Ford dealer can tell you from the VIN which this car has.

  At the viewing: Ask whether it has a belt or a chain, and for a full service history with the right oil.
