NHTSA Preliminary Evaluation PE23015

On September 20, 2023, the Office of Defects Investigation (ODI) opened PE23-015 to investigate instances of engine failure due to loss of oil pressure in model year (MY) 2018-2021 Ford EcoSport vehicles. Some consumers reported a low engine oil pressure warning lamp immediately preceding a complete loss or reduction of motive power while the vehicle was in motion. The investigation revealed that the engine oil pump drive belt tensioner arm may fracture, separate from the tensioner backing plate, and/or the oil pump drive belt may degrade and lose teeth, resulting in a loss of engine oil pressure. A loss of engine oil pressure can result in engine seizure, which can result in a loss of motive power and a loss of mechanical vacuum pump required to provide power braking assist, increase the risk of a crash. On December 22, 2023, Ford filed recall 23V-905 for certain MY 2016-2018 Ford Focus and 2018-2022 Ford EcoSport vehicles. The recall remedy provides the replacement of the oil pump drive belt tensioner assembly and oil pump drive belt with redesigned parts to improve robustness. In view of the recall action being taken by Ford, ODI is closing this Preliminary Evaluation. The agency reserves the right to take additional action if warranted by future circumstances.
