2016 Ford Fiesta Powertrain & Transmission Problems

The transmission started slipping in 1st and 2nd gear.

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 slave cylinder in this location. The current placement appears to be for no other reason then planned obsolescence. Vehicle has stalled in traffic multiple times, cannot complete shifts due to clutch pedal sticking to floor. Inability to properly operate transmission as expected per mileage with a manual vehicle is a safety hazard. This is a safety concern due to limited ability to engage warning lights being that the shifter needs to be operated as well as the vehicle needing to be steered. Inability to depress the clutch to mechanical certainty limits the drivers ability to confidently navigate to a safe area to assess the vehicle's possible malfunctions. This limits the ability to warn other motorists on the roadways, which can cause accidents that may also cause injury/fatality depending on the speeds driven.

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.

This car has a double clutch transmission that was done overseas evidently this car's transmission does not run right and I've had it tested out at a mechanic shop the transmission slips gears does not operate correctly I was told by the mechanic that is not a normal transmission it can cause an accident you put your foot on the gas the car will rev into the wrong speed stay keep the tachometer running in the red and could cause a serious accident to other people and that Ford will not fix it as it was manufactured incorrectly the first time this car is dangerous and now I'm stuck paying for a used car that could cause an accident Ford denies any culpability.

2016 Ford Fiesta with vin: [XXX] with build date of 7/20/2015 at Cuautitlan plant with 6 speed Powershift auto transmission. Current miles on vehicle are 128,842. Ford Motor Company issued Customer Satisfaction Program (CSP) 14M02 on 6/14/2015. Since this date there have been 7 supplements to this program. The changes are that they are covering more vehicles with this KNOWN defective transmission. The first supplement covers vehicles with build date before 10/15/2014 and the most up to date supplement covers vehicles with build date before 6/30/2015. All of the supplements cover the same transmission. This is the transmission that my Fiesta has. I have spoken with the Ford Vehicle Concern team numerous times requesting to speak with Stacy Balzer, Operating Director, service Engineering Operations, Ford Customer Service Division since she is the one that has been signing the updated supplements. Ford has issued Technical Service Bulletin (TSB) 16-0129 that includes my specific vehicle. My complaint is that Ford Motor Company knows that my transmission is defective per TSB 16-0129 but the latest CSP 14M02 supplement dates don’t currently cover my vehicle. My Fiesta would be covered if it was built 20 days earlier. I see this as an extremely shady form of business and instead of waiting until they issue another supplement that would probably cover my vehicle I have chosen to make a written complaint. The NHTSA website has 88 power train complaints towards a 2015 Ford Fiesta (currently being covered in CSP 14M02) and has 86 power train complaints towards a 2016 Ford Fiesta. I have had the vehicle inspected at my local Ford dealership and they have stated that the issue is a defective transmission. A defective transmission that IS NOT covered under CSP 14M02 because of build date ONLY. Thank you for your time.
