Some 2018-2019 EcoSport vehicles equipped with a 1.0L EcoBoost engine and a 6F15 automatic transmission and built on or before 3-Apr-2019 may exhibit a loss of engine oil pressure with an illuminated oil pressure warning lamp. This may be due to a broken/failed engine oil pump belt tensioner which leads to a loss of engine oil pressure. Due to the nature of this failure, an engine replacement may be required. Engines built after 3-Apr-2019 should not be affected. All tensioners built with a manufacture date on or after 23-Jan-2019 are good to use.
