What owners say about the power train

Verbatim from NHTSA complaints, newest first
“While driving, my son's car started to have issues when it was shifting gears (it's an automatic). Then a warning came up on the dash saying something like "Transmission malfunction, service immediately". We were on our way to a mechanic to pick up another vehicle so we left it with them. They confirmed the issue and stated it is related to the clutch system (which I believe is the dry clutch system that has been recalled with similar car models). We have not taken it to the manufacturer/Ford dealership yet, but are trying to figure out our options on this faulty transmission design. Not aware of any issues prior to this incident.”

The car then displayed error lights (yellow CEL, yellow wrench icon, HEAD unit showed "transmission issue service immediately" This is a direct result of the DPs6 transmission put into all 7th gen Ford Focus/Fiesta models. This DCT transmission has been replaced 3 times for this particular car and failed the same manner each time - meaning 3 near accidents have occured because this transmission fails. Across the USA; more than 50 people have been injured as a result of this transmission failing.”

“The contact owns a 2012 Ford Fiesta. The contact stated that upon taking the vehicle to a gas station for servicing, the contact was informed that the brake calipers were sticking, and the calipers and rotors were extremely hot. The calipers and rotors were replaced; however, the failure persisted. The vehicle was taken to the dealer, where it was diagnosed and determined that the transmission axle shaft had damaged the splines. The dealer determined that the transmission needed to be replaced. The vehicle was not repaired due to the cost. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 42,000.”

“Transmission unexpectedly malfunctions. Car lost the ability to shift into reverse and even numbered gears. rough shifting when it can shift. slipping when attempting to drive. Unable to accelerate from a stop sign. Based on simple web searches, the Ford fiesta and Focus with the DPS6 transmission are notorious for defective transmissions.”

“It is widely known that this vehicle has irreparable transmission problems. My car shudders, loses power, has issues shifting, etc because of known issues. It feels dangerous to drive at times. The dealer no doubt willingly sold it to me used knowing about the problem. I feel taken advantage of as I had to purchase the car during Covid when inventory was low and prices were high. I owe over twice as much on car than it’s worth. No one in their right mind would buy it. I’m on medical leave without pay and in no position to trade it. I bought it after all the class action suits were settled. It doesn’t appear to fall under lemon law. I’m basically waiting for it to completely break down. Praying nobody is hurt when it happens. I’m writing because I’m aggravated and feel I have no recourse.”
