Period mentioned: 2019 onwards

Possible cause described: Recalls: battery earth on 2020 cars (tightened to the correct torque), a battery connection that could overheat, eCall software (about 300 cars in Germany) and a steering-wheel airbag that could come loose (a retaining spring is added).

1.0 EcoBoost wet belt: blocked oil pumpEngine

Engine / equipment: 1.0 EcoBoost three-cylinder with oil-immersed belts
Period mentioned: Approx. 2014–2021
Symptoms: Low oil-pressure warning just before a loss of power; sometimes the engine seizes without warning. With no oil pressure the vacuum pump that assists braking can also stop working.
Possible cause described: The oil-immersed belt material can degrade and shed debris that blocks the oil-pump pickup screen; the tensioner arm can also break. The US agency (NHTSA) is investigating almost 136,000 cars; most failures happened before the belt-change interval.
Check for the garage: With the oil-pressure warning, stop and do not restart. At the garage, check the belt and tensioner and look for debris in the sump and pump screen; use the exact oil Ford specifies and do not stretch the change intervals.
