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 [redacted]. 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 Visual comparison of the faulty relay matches the obsolete part as well, and differs from the correct superseded part number relay outlined in the 16B11 bulletin.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. …
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 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.
On Sunday December 4th 2022 my car battery died. I called aaa and they sent out a tow company to jump the battery. I noticed for about a month the car made a "ticking" noise. The noise would sound like a "sighing" when parking the vehicle. The passenger side door latch is broken and will no longer lock my door. My minor daughter used to sit up there but now because the door flys open she can no longer sit there. This is a serious safety hazard and needs to be recalled on Ford Fiesta 2016 as well.
Alarm is constantly going off which means I don't know if it's a real intruder or just the door ajar switch, recall affected up until 2015 but the issue keeps going into 2016 ford fiestas, this is a safety issue as we cannot tell if someone is breaking into the car
2016 ford fiesta se has had a transmission/clutch problem. It is doing everything that the recall says it's suppose to cover and Ford is not willing to honor and fix it. It's jerking, shaking, and not accelerating properly.
