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…

What stands out
No new NHTSA electrical complaint has been filed on this vehicle in over 3 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: The 2016 Ford Fiesta shows a cluster of electrical issues that range from inconvenient (non-working horn, dim lights) to serious safety hazards (randomly opening trunk, unreliable door latches, battery failure at highway speed, engine fire, stalling). The most common complaint is a trunk that pops open multiple times daily, creating security and battery-drain problems that dealers struggle to fix. Multiple owners report that critical issues like stalling and acceleration loss can't be reproduced, leaving them unresolved.
Owners of 2016 Ford Fiesta report a range of electrical failures. The most frequent complaint is a trunk latch that releases randomly while driving or parked, sometimes multiple times daily, activating interior lights and risking battery drain. Several owners note the issue is hard to reproduce at a shop, complicating diagnosis.
Door latch failures appear in multiple complaints—driver and passenger side doors failing to latch reliably, some attributed to child locks. Owners cite this as a safety hazard, particularly with children in the vehicle.
Battery-related issues include premature battery death without warning, a key fob battery requiring replacement, and one report of a key battery failure that killed power at highway speed with no warning or brake lights. A cooling fan relay failure is alleged to have melted the fuse box and caused engine overheating and permanent damage; the owner claims the vehicle matched a Ford Customer Satisfaction Program (CSP) bulletin but Ford refused coverage.
Window and accessory controls malfunction: passenger-side window control inoperative, Bluetooth audio pausing without reason, and a non-functioning horn at delivery. Dashboard lighting issues include an airbag warning light that stays on, a tire pressure light, and fluctuating instrument cluster brightness.
Other electrical complaints include a stalling issue at intersections that couldn't be reproduced, check engine light illumination, a defective purge valve (reportedly linked to the capless fuel tank design), an engine fire at 23,500 miles with no warning, and a malfunctioning security alarm that can't distinguish real intruders from false triggers.

The horn does not work. I never tested the horn when I took the car for a test drive, and only discovered this fact 2 weeks after driving the vehicle.. The dealer claims they did a thorough safety check which is not the case. I signed the 'sold as is' waiver so I don't have much recourse here, but the dealer should be held accountable for selling a vehicle that does not meet the basic safety…
Over the summer 2019, passenger left side door did not latch. Child lock was on. Upon discovery of defect, it was taken to Ford to repair. On november 12, 2019, driver's side door did not want to latch. Went to check on the car next day, and the door latches without problems more than once. Filing a complaint because it has happened twice in the same year with different car doors. Will take to…
