2017 Ford Fiesta

Still open engineering analysis · opened July 31, 2026

the engine, the engine and its cooling

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 while driving due to a lack of engine lubrication. The failure data provided in response to this investigation revealed an average failure mileage of approximately 70,000 miles, and that 98% of the failures occurred prior to the 150,000 mile timing belt replacement interval per the vehicles’ maintenance schedule. Based on evidence collected via consumer surveys and an engine teardown, failures have occurred despite evidence of proper and routine oil maintenance. The oil pump pick-up screen is not serviceable, so debris accumulation cannot be inspected or manually removed without removing the engine from the vehicle. On June 2, 2026, Ford informed ODI of a non-safety customer satisfaction program for global vehicles with the 1.0L Fox Classic Timing Belt. This program will notify customers globally of a revised maintenance interval for the timing belt, reducing the original 150,000 mile interval down to 100,000 miles/6 years. This customer satisfaction program will also offer reimbursement to eligible customers who previously paid to have their engine repaired or replaced due to a timing belt related issue. Based on NHTSA’s analysis of the data, failure rates, information provided by Ford, preliminary engine teardown analysis, and precedent recalls regarding loss of engine oil pressure with the presence of driver facing warnings, ODI believes there is an unreasonable risk to motor vehicle safety. ODI is opening this Engineering Analysis to perform component-level and vehicle testing. To review the reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

The A/C vent actuating solenoids under the dash have all failed. They don't allow the cool air to be routed properly. We have had the dealers service center check each time as they would fail, and they found replacement is needed at each visit. The actuators began failing at 6,000 miles, and continued dropping off one by one at various mileage until all three are now not functioning. My car has 11,500 miles now. The solenoids just click now constantly while driving as all three try to activate the vent doors.

The contact owns a 2017 Ford Fiesta. The contact stated while driving at various speeds, the vehicle jerked and experienced hard shifts from first to second gear and from second to third gear. The contact stated that the RPM were significantly high prior to shifting gear, then decreased before the vehicle accelerated as intended. The contact stated that the transmission had failed to shift to reverse(R). The contact stated that DTC: 4P07A5; was retrieved, indicating transmission friction element B stuck On. An unknown dealer was notified of the failure. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and a case was filed. The manufacturer referred the …

I have this car since 2019 with 8000 miles and this is the 3rd time the code came up for the evap system to be repaired. P0456. The first time it was replaced was at mileage 47084 at winner Ford dealership. On June 11th 2021. The second time it was replaced was at Winter Ford dealership on March 17th 2022 with mileage 59,678. The light just came on today and the code came up again. PO456. I now have 102,000 mi on my car. I think that this should be a recall worth looking into. Thank you

The contact owns a 2017 Ford Fiesta. The contact stated that while driving at 65 MPH, there was an abnormal knocking sound coming from the vehicle, and the vehicle started to lose motive power. The contact was uncertain if any warning lights were illuminated. Due to the failure, the vehicle was towed to an independent mechanic, where it was discovered that the engine oil pump belt needed to be replaced. Upon investigation, the mechanic linked the failure to NHTSA Campaign Number: 23V905000 (Engine and Engine Cooling). The vehicle was then towed to a dealer and the cause of the failure was confirmed, but the contact was informed that the vehicle was not included in the recall. The contact …
