23V-905Dec 22, 2023
Engine And Engine Cooling:Engine:Oil/Lubrication:Pump

Ford Motor Company (Ford) is recalling certain 2016-2018 Ford Focus and 2018-2022 Ford EcoSport vehicles. The oil pump drive belt or drive belt tensioner may fail, resulting in a loss of engine oil pressure.

Risk and remedy
Risk: A loss of oil pressure can result in an engine stall and a loss of power braking assist, increasing the risk of a crash.
Remedy: Dealers will replace the oil pump tensioner assembly and oil pump drive belt, free of charge. If engine failure occurs due to a damaged oil pump belt and/or oil pump belt tensioner, Ford has authorized dealers to replace the engine assembly as an interim repair before the availability of remedy parts for the final repair.

Timing belt failure. Open.

NHTSA summary
On December 18, 2025, the Office of Defects Investigation (ODI) opened PE25020 to investigate instances of timing belt failure in model year (MY) 2015-2017 Ford Fiesta and MY 2015-2018 Ford Focus vehicles manufactured by Ford Motor Company (Ford), equipped with a 1.0L engine and manual transmission (subject vehicles). Additionally, MY 2018-2021 Ford EcoSport and MY 2016-2018 Focus vehicles with a 1.0L engine and automatic transmission were analyzed as peer vehicles because they utilize a wet timing belt comprised of similar material as the timing belt in the subject vehicles. Through the PE, ODI investigated a potential failure/degradation of the timing belt that may affect oil pump function resulting in a lack of engine lubrication and potential loss of motive power. The complaints commonly allege a low engine oil pressure warning lamp immediately preceding a complete loss or reduction of motive power while the vehicle is in motion. Some complaints allege that a sudden loss of motive power or engine seizure occurred without warning or prior detectable symptoms. ODI’s analysis supports that this failure can occur without sufficient and advanced warning to the driver that a loss of motive power/engine seizure is imminent. ODI found that the timing belt material may degrade and create debris that clogs the mesh oil pump pick-up screen, resulting in reduced oil pressure in the engine. As additional debris accumulates on the screen, this can progress to a loss of motive power

Oil pump failure. Closed feb 14, 2024, led to recall 23V-905.

NHTSA summary
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.

Fuel system · model years 2012 to 2018

Loss of motive power. Closed dec 20, 2024.

NHTSA summary
On September 15, 2023, the Office of Defect Investigation (ODI) opened this Recall Query (RQ) after receiving 98 consumer complaints alleging loss of motive power in model year (MY) 2012-2018 Ford Focus vehicles. The RQ focused on the effectiveness of the remedies of Recall 18V-735 and 19V-515. In October 2018, Ford issued Recall 18V-735, which updated Powertrain Control Module (PCM) software in MY 2012-2018 Ford Focus vehicles equipped with 2.0L GDI engines built prior to April 13, 2017, and those with 2.0L GTDI engines built prior to February 2, 2018. The recall addressed vehicles experiencing a malfunctioning Canister Purge Valve (CPV) that can stick open and PCM software that does not adequately detect a stuck-open CPV condition. A CPV that is stuck open can cause excessive vacuum in the fuel vapor management system, potentially deforming the fuel tank, collapsing on itself. This deformation of the fuel tank can cause a Malfunction Indicator Light (MIL) to illuminate, an inaccurate or erratic fuel gauge indication, drivability issues, and/or loss of motive power. In July 2019, Ford issued Recall 19V-515, which addressed certain MY 2012 and MY 2017 Ford Focus vehicles equipped with 2.0L GDI and MY 2013-2014 Ford Focus vehicles equipped with 2.0L GTDI engines whose PCM software had been reprogrammed as a part of recall 18V-735. The updated software calibrations for these subject vehicles were not properly installed by Ford at the time of production. Approximately one year a

Pedestrian alert sounds. Closed aug 7, 2023, led to recall 22V-063.

NHTSA summary
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

Engine stalling. Closed jan 16, 2004, led to recall 03V-482.

NHTSA summary
CLOGGING OF THE FUEL DELIVERY MODULE (FDM) FILTERS IN THE SUBJECT VEHICLES CAN LEAD TO STALLING AND OTHER RELATED SYMPTOMS.THESE SYMPTOMS BECOME INCREASINGLY OBVIOUS TO THE DRIVER AS THE CLOGGING GRADUALLY INCREASES OVER EXTENDED PERIODS OF DRIVING.STALLING IN THESE VEHICLES IS MOST LIKELY TO OCCUR WHEN ACCELERATING THROUGH A RIGHT HAND TURN SUCH AS MERGING INTO FREEWAY TRAFFIC WHEN THE FUEL LEVEL IN THE FUEL TANK IS LESS THAN 1/4 FULL.MORE THAN 90% OF THE STALLING COMPLAINTS PERTAIN TO THE ORIGINAL DESIGN FDM INSTALLED IN MY 2000 AND 2001 (PARTIAL YEAR) FOCUS VEHICLES. FORD HAS DECIDED TO CONDUCT A CAMPAIGN (03V-482) TO ADDRESS STALLINGIN THESE VEHICLES.THE SMALLER NUMBER AND RATE OF COMPLAINTS ASSOCIATED WITH THE INTERIM AND CURRENT FDM DESIGNS INDICATE IMPROVEMENT BUT ALSO REFLECT A SHORTER TIME IN SERVICE FOR THESE DESIGNS. ACCORDINGLY, ODI WILL MONITOR THE STALLING PERFORMANCE OF MY 2001 - 2002 FOCUS VEHICLES EQUIPPED WITH INTERIM AND CURRENT DESIGN FDMS.

Should you keep driving it?

This page can't tell you that. 0 of 144 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
