Customer satisfaction program 16B11 covers a faulty high speed cooling fan relay. This bulletin was issued on April 5, 2016. I purchased the vehicle on [XXX]. An incorrect relay was installed at the factory, and the program should have replaced the relay with the correct part. This was not performed on my vehicle before I purchased it from Sheehy Ford of Ashland. The faulty relay failed, melting the fuse box in the process and causing the vehicle to overheat and cause permanent severe engine damage. Remnants of the melted relay show the part number, which matches the obsolete part number. Visual comparison of the faulty relay matches the obsolete part as well, and differs from the correct superseded part number relay outlined in the 16B11 bulletin. Ford Motor Company insists my vehicle was not a part of this program and any repairs will not be covered. The build date, make/model/engine, assembly plant and most importantly, part number of the relay and mode of failure exactly match the 16B11 CSP bulletin. Ford denies that there is any issue with my vehicle. Local Ford dealers refer me to Ford Motor Company to escalate this problem, but Ford refuses to investigate.

Vehicle was traveling on an interstate highway when the oil indicator lamp lit, and the car immediately lost power, putting it in danger of being rear-ended. I researched any recalls and found "Part 573 Safety Recall Report 23V-905", which only covers two different models, the Focus and the Eco Sport, with precisely the same EcoBoost 1.0 Liter engine. I recently sent it to an independent service station to perform that which the recall describes, as a recall notice did not happen, but the service foreman stated it cannot be successfully repaired, as the oiling system was completely compromised, causing catastrophic damage to the valves, cylinders, turbo system, and vacuum pump.

At 90,000 miles the Engine Timing Crankshaft Sprocket (i.e Crankshaft Gear,Part #: BE8Z6306AD) holding the timing belt on the vehicle has failed. This resulted in the timing belt backing off the cam gears and coming in contact with and melting through the plastic timing belt cover. Luckily, there was an audible grinding noise coming from the engine that alerted us the problem before the timing belt became dislodged. On further review there are numerous cases on the internet of this situation occurring. Please see examples at: [XXX] , [XXX] , and [XXX] . The service interval for this component established by Ford is 150,000 miles. Therefore, these situations represent an early failure of this engine component and poses a safety risk to drivers if the belt comes off track or breaks during operation because the vehicle could immediately lose power. The attached image shows the timing belt melting through the plastic timing cover. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While changing gears at low speed, the vehicle was shaking and shuddering. While driving approximately 30 MPH, the RPM raised up to 3,000 RPM. While attempting to accelerate from a stop, the vehicle failed to move. Additionally, while depressing the brake pedal, the vehicle accelerated. The check engine warning light was illuminated. The contact called the local dealer, but the vehicle was not diagnosed or repaired. The vehicle was previously taken to the local dealer where it was diagnosed that a vapor valve replacement was needed. The vehicle was repaired but the failure persisted. The manufacturer was contacted and referred the contact to the NHTSA Hotline. The failure mileage was approximately 112,000.

2EA26004 · Timing Belt Failure
Opened Jul 31, 2026 · No close date supplied
Status: open (inferred from source dates) · Engine; Engine And Engine Cooling:engine:gasoline:belts And Associated Pulleys
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.
