I’ve owned my 2015 Ford Fiesta for about 7 years now. Within the first year, I contacted the Ford dealership explaining noises when driving and my dual clutch shifting gears. I sent them video sound recordings. They said it was typical of this transmission. The car has never felt smooth but “ok enough,” until 18months ago when I reported gears slipping. No error codes were detected but parts of my clutch were replaced. Now, 16,000 miles later I brought my car into ford dealership saying I felt the gears slipping. They diagnosed a few other maintenance pieces like brakes and tires but said nothing was detected with the transmission and clutch. 3 weeks later, I was driving on a highway - lake shore drive in chicago, and my check engine light came on. My car would not change gears or accelerate past the 30mph I had been going. I felt like I was in neutral. I exited, fearing an accident. In stop and go traffic I used my hazard lights because I could not accelerate at each stop sign. I made it to a safe spot to pull over and then realized i could not reverse! I had my car towed to the ford dealer from 3 weeks prior. At this point they could read a few clutch error codes but cannot be certain of the actual cause. In order to do so, they need my consent of a possible $1500 service charge for investigating the issue. Ford costumer service line has said “oh wow, we’re glad your weren’t in an accident. I’m Sorry, your car does not meet criteria for any support from Ford.” Ford has knowingly kept these faulty transmissions on the road and now they are telling me that they will not help look into my vehicle’s transmission and safety issues. This seems unreasonable when the issue is clearly linked to the faulty dual clutch Powershift system. 1.5 million Ford Fiestas may still be registered and driven with Ford offering nothing other than “I’m really glad you dodged an accident and made it off the highway.”

The contact owns a 2015 Ford Fiesta. The contact stated while driving at various speeds, the transmission slipped from drive(D) to neutral(N) and the vehicle shuddered significantly. There was no warning light illuminated. The contact veered to the side of the road. The contact turned off and restarted the vehicle, and the vehicle responded as needed. The contact stated that the failure had been reoccurring while driving and would persist at times while turning off and restarting the vehicle. The vehicle was taken to the dealer who informed the contact that the gear shifter failed, and the failure was related to an unknown Ford Campaign Number that had expired. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

When accelerating, there is a shuddering sensation as you can feel the clutches slipping. The shifting is also sluggish at times. When in "sport mode" an error state can occur where the transmission fails to shift gears altogether and a warning comes up on the dashboard to service the transmission immediately. While that error is up, the shuddering becomes much worse and the engine will try to lurch forward at random times when it chooses the wrong gear. This lurching will fight the brakes too, decreasing stopping distance if the driver isn't extra diligent. This error state is cleared by stopping and starting the car again. There are no other visible dashboard warnings associated with this issue in daily driving. I took it to a local service center to be diagnosed and they determined it was either a worn clutch or a faulty TCM in need of a replacement. I took it to the Ford dealership in the area, and they narrowed it down to the clutch and not the TCM. Ford issued an extended warranty for this issue on other 2015 Ford Fiestas, but mine fell just outside the required build date despite having identical symptoms as what the warranty was for on the other cars. The car is only 7 years old with 92k miles on it, so if it was part of the aforementioned extended warranty (7 years or 100k miles) it would qualify, but not for much longer. This seems to be a known issue that Ford never fixed despite the car being outside the extended warranty cutoff.

Transmission slips out of gear during normal city driving. I have had the car completely lock up, become unable to drive, and needed to be towed to the dealership. This is the 3rd time I have encountered this issue. I've had the transmission computer restarted, one of the clutches replaced, then a few months after that had the car towed to the dealership again due to "immobilizer malfunction" design for the car is great but the mechanics are terrible.

My transmission is slipping. When trying to accelerate, engine will rev, RPM increase, but speed won't change. This is caused safety issues for myself and my passengers as it is difficult to increase speed and keep up with on going traffic. My car is unsafe to drive.

Manual transmission slipping on first gear. I almost have a collision due to the problem, I was ready to turn on a busy intersection when the slipping happen and just because the other vehicle stop, I didn't have the collision head on. So I decided to take it to the ford dealer for repairs, when after diagnostics I was told by the service advisor that they need to do an overhaul on the manual transmission after my vehicle is driving for less than 9500 miles.

Many times, my car does not down shift after being in a passing gear and then letting off the gas. It stays at 5,000 RPM for a few seconds. July, 2018, my car was stopped as I was waiting to make a left turn. As I pressed on the gas to turn left, my car slipped into neutral. Because my brake lights weren't on, my car was hit from behind by an approaching car. September 3, 2018 my car was stopped, I put it into reverse to back into a parking spot. When I pressed the accelerator the car shimmied and moved forward instead of reverse.
