2016 Ford Fiesta power train problems

“I have come to find that this vehicle suffers from premature slave cylinder failure, there are roughly 62,000 miles on the vehicle. Typical failure is reported to Ford between 70,000 and 80,000 miles. First symptoms appeared at roughly 58,000 miles. As I am a single father and a full time communications worker, I was not able to address this issue immediately upon discovering the initial symptoms as it would need further diagnosis. Clutch hydraulic fluids appear to be well sealed and clean. The design flaw with this system should be relatively obvious to a major automobile manufacturer such as Ford. The excessive temperatures caused by the transmission can and will affect any hydraulic systems severely. There are no avenues in which the temperatures can escape due to the bell housing of the transmission encasing the slave cylinder. In my experience as a prior automotive technician, most manual transmission automobiles place the cylinder in a more reasonable location, for example, beside the break booster in a 1991 Dodge Stealth. When observing the firewall in this location on this model of vehicle I can confidently say there is enough room to place a clutch…”

“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.”

“The TCM was defective. It has been known that the TCM, transmission control modules are defective for Ford Fiestas and Focus. My daughter was driving the car and it stalled. If she was in heavy traffic are making a turn when this happened she could have been seriously injured. Ford said that they fixed this issue in the 2015 editions, that's why they stop the recall for 2016 models, but they really did not fix the problem. The vehicle was taken to a Ford dealership in Wisconsin and they confirmed all this information to me. And eight hundred dollars was paid to fix a problem that is on a recall for most models except the 2016, because they supposedly fixed the problem.”
