There are 14 owner-reported engine complaints for the 2016 Ford Fiestain NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The contact owns a 2016 Ford Fiesta. The contact stated while driving at approximately 30 MPH, and depressing the accelerator pedal, the vehicle failed to accelerate as intended and the vehicle started shuddering. The contact pulled over to the shoulder of the roadway to restart the vehicle, but the failure reoccurred. The messages "Mobilizer Malfunction" and "Engine Service" were displayed on the instrument panel. The local dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 138,000.
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)
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.
I turned my car on July, 14, 2023 , I put my foot on the break to put in reverse, and when I put it in reverse it would not reverse and my brakes locked up and my car would start to roll forward while I was in reverse gear . My car drives forward but will not go in reverse and my engine light is not own. I took it two different shops , both with the same diagnois's , said it is my transmission and to contact Ford dealership directly for any possible recalls.
The contact owns a 2016 Ford Fiesta. The contact stated that while operating the vehicle, there was a continuous swishing sound coming from the engine compartment.
