Symptoms: No-start condition (wouldn't crank w/o jump); delayed or harsh shifting; lost power (stalled going up tiny hill). Warning lights: transmission malfunction - service now; check engine light. Our symptoms and warning lights are consistent with Ford's Fiesta Transmission Control Module recall, however the VIN for our car is not part of the original recall. We meet all of Ford's recall eligibility criteria: reported before June 30, 2025; vehicle is less than 10 years old; vehicle has fewer than 150,000 miles. By virtue of the symptoms, warning lights and meeting Ford's other criteria strongly suggest our VIN should be included in the recall.
