“The contact owns a 2016 Ford Fiesta. The contact stated while driving approximately 60 MPH, the vehicle was losing motive power. The check engine warning light was illuminated. The vehicle was taken to the dealer to be diagnosed and it was determined that the spark plugs needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the same dealer who diagnosed the vehicle and determined that the ignition coils needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken to an independent mechanic who diagnosed the vehicle and determined that the TCM needed to be replaced. The vehicle was not repaired. The contact researched online and related the failure to Customer Satisfaction Program: 14M02 (Power Train); however, the VIN was not included. The manufacturer was informed of the failure and referred the contact to NHTSA Hotline to report the failure. The failure mileage was approximately 130,000.”

“The contact owns a 2016 Ford Fiesta. The contact stated that while driving at an undisclosed speed, the vehicle failed to accelerate as intended while depressing the accelerator pedal. The check engine warning light was illuminated. The contact stated that the failure persisted. The vehicle was taken to an independent mechanic; however, no cause for the failure was found. The mechanic informed the contact that it was possibly the battery and the key fob battery that had caused the issues. The contact took the vehicle to the dealer where the key fob battery was replaced. The contact replaced the battery independently. The check engine warning light was illuminated. The manufacturer was not notified of the failure. The failure mileage was unknown.”

“Customer satisfaction program 16B11 covers a faulty high speed cooling fan relay. This bulletin was issued on April 5, 2016. I purchased the vehicle on [XXX]. An incorrect relay was installed at the factory, and the program should have replaced the relay with the correct part. This was not performed on my vehicle before I purchased it from Sheehy Ford of Ashland. The faulty relay failed, melting the fuse box in the process and causing the vehicle to overheat and cause permanent severe engine damage. Remnants of the melted relay show the part number, which matches the obsolete part number. Visual comparison of the faulty relay matches the obsolete part as well, and differs from the correct superseded part number relay outlined in the 16B11 bulletin. Ford Motor Company insists my vehicle was not a part of this program and any repairs will not be covered. The build date, make/model/engine, assembly plant and most importantly, part number of the relay and mode of failure exactly match the 16B11 CSP bulletin. Ford denies that there is any issue with my vehicle. Local Ford dealers refer me to Ford Motor Company to escalate this problem, but Ford refuses to investigate.”

“Trunk latch releases randomly. Like so many other people with this generation of Ford Fiesta. They have taken them in for the same issue and told they don't by the shop that they don't know what the problem is. The problem is random so getting to to happen while at the shop is next to impossible. If the problem can't be reproduced by a garage mechanic, how would Insurance, or police have any luck? There needs to be a recall, because some people are having them pop open while driving at night, and all of a sudden the interior lights come on, safety hazard!!! Some will pop open and kill the battery because the dome light comes on when the trunk opens. Then you're standing in subzero temperatures trying to jump start the car. That in and of itself is a safety issue. No warning lights are associated with this.”

“The contact owns a 2016 Ford Fiesta. The contact stated while driving at an undisclosed speed, while the transmission was shifting between 1st and 2nd gear, the vehicle was shaking until the transmission had shifted to the higher gears. The contact stated that occasionally the vehicle failed to start intermittently. There were no warning lights illuminated. The vehicle had not been taken to the dealer. The vehicle had not been diagnosed or repaired. The contact also stated that the battery had been replaced by a friend approximately 7 times, and once by an O' Riley’s within the past 2 years. The manufacturer was made aware of the failure. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was 80,100”
