The contact owns a 2016 Ford Fiesta. The contact stated that while driving at an undisclosed speed, the vehicle failed to accelerate as intended while depressing the accelerator pedal. The check engine warning light was illuminated. The contact stated that the failure persisted. The vehicle was taken to an independent mechanic; however, no cause for the failure was found. The mechanic informed the contact that it was possibly the battery and the key fob battery that had caused the issues. The contact took the vehicle to the dealer where the key fob battery was replaced. The contact replaced the battery independently. The check engine warning light was illuminated. The manufacturer was not notified of the failure. The failure mileage was unknown.

The contact owns a 2016 Ford Fiesta. The contact stated that the transmission was not working as designed. While driving at various speeds, the vehicle accelerated abruptly. 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.

Defected transmissions were installed on these cars. Ford recalled the least number with the least loss, but they kept the rest with their defected transmissions which cost more money than the car’s value. Ford sold their cars with defected transmissions and they knew it!

FORD DEALERSHIP "FIXED" THE TRANSMISSION ON 7-24-19 EXCEPT IT'S NOT FIXED. AT A STOP WHEN PRESSING THE GAS THE CAR WON'T MOVE THEN SUDDENLY LAUNCH FORWARD RANDOMLY. IT ALSO STILL LOSES ALL ENGINE POWER WHILE DRIVING DOWN THE ROAD. THESE WERE THE SAME SYMPTOMS AS BEFORE THE "FIX". THIS ISSUE HAS CAUSED A MINOR ACCIDENT AS WELL. WE GOT LIGHTLY REAR ENDED WHEN A LIGHT TURNED GREEN, WE STARTED MOVING FORWARD AND AT ABOUT 7-10MPH WE LOST ALL POWER AND THE PERSON BEHIND US COULDN'T STOP QUICK ENOUGH. DAMAGE WAS MINOR, JUST SOME CHIPPED PAINT BUT IT COULD HAVE BEEN MUCH WORSE.

TL* THE CONTACT OWNS A 2016 FORD FIESTA. WHILE DEPRESSING THE BRAKE PEDAL, THE VEHICLE CONTINUED TO LUNGE FORWARD WITHOUT WARNING. AT TIMES, WHILE APPLYING PRESSURE TO THE ACCELERATOR PEDAL, THE VEHICLE WOULD STALL AND THEN SLOWLY PICK UP SPEED. THERE WERE NO WARNING INDICATORS ILLUMINATED DURING THE FAILURES. THE CONTACT ALSO STATED THAT THE VEHICLE SHIFTED INTO NEUTRAL WHILE IN DRIVE, WHICH CAUSED THE VEHICLE TO OVERHEAT WITHOUT WARNING. THE VEHICLE WAS TAKEN TO GALPIN FORD (1000 SANDRETTO DR, PRESCOTT, AZ 86305, (877) 826-2935) WHERE IT WAS DIAGNOSED WITH A FAULTY TRANSMISSION. SINCE OWNING THE VEHICLE, THE CONTACT HAD THE TRANSMISSION CONTROL MODULE REPLACED TWICE. THE MANUFACTURER WAS NOTIFIED OF THE FAILURES AND PROVIDED THE REPAIR COST. THE FAILURE MILEAGE WAS 39,000.

IT WOULD ALSO SEEMINGLY GO INTO NEUTRAL ON THE HIGHWAY WHICH LED TO A COMPLETE LOSS OF ENGINE POWER. THIS ALSO HAPPENS WHEN ON A NORMAL ROAD AT ANY SPEED AND IS COMPLETELY RANDOM AND ONE TIME AT A RED LIGHT WE BEGAN TO ACCELERATE THEN POWER SUDDENLY CUT OUT AND WE GOT REAR ENDED LIGHTLY. I TOLD PETER'S FORD IN NASHUA NH DURING OUR 1ST 3 OIL CHANGES ABOUT THE ISSUE AND WAS TOLD IMPLICITLY THAT IT WAS COMPLETELY NORMAL AND I SHOULDN'T WORRY ABOUT IT AS IT WILL JUST GO AWAY ON ITS OWN.

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.
