Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
Owners report a constellation of intermittent electrical failures in the 2015 Lincoln MKZ. The most serious involve sudden power loss while driving—one owner lost all power at 30 mph while entering a freeway with a "Power Accessory" warning light; another experienced complete shutdown at low speed after months of strange humming near the fuel tank. Multiple owners describe simultaneous failures of the airbag warning light illuminating, AC shutting off, power windows and seats freezing or moving on their own, and radio cutting out—some report this occurring eight times or more. Seat memory functions have failed to engage properly, leaving seats reclined and steering wheels raised, impairing pedal and steering access. Battery problems span repeated failures within short ownership windows: one owner replaced the battery three times; another four times in under 50k miles, though dealers attributed each to bad batteries rather than parasitic drain. Horn failures are intermittent, working inconsistently; seatbelt warning sensors fail to trigger when occupied or unbelted. One owner's brake pedal went to the floor coinciding with dashboard lights flashing and clicking noises. A faulty electrical harness was diagnosed in one case. Repair attempts have been ineffective or inconclusive, with dealers unable to identify root causes despite multiple service visits and warranty coverage still active.

It started months ago with a strange humming noise coming from the back of the car on the right side ,where the gas tank is. It would come and go very couple of weeks. My mechanic checked it out and found nothing. One day, with the humming sound very loud , the car lost power while driving, almost crashed. Had it towed back to the mechanic ,who I trust and again could find nothing. I called a…
In under 4 years/50k miles battery has been changed 4 times. Every time the cause is a bad battery and not a draw. There is an underlying issue with the mkz electrical architecture. Dealer says this is a common problem.
This vehicle has been in service 14 times in 16 months for various intermittent electrical and sensor problems. It was purchased new in june 2015 and currently has 14k miles. It has several major issues but the two safety risks are: 1) the driver seat is supposed to automatically recline and the steering wheel adjusts upward to allow the driver to exit the vehicle when the ignition is turned off.…

Independent shops typically charge around $850 for electrical repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to electrical?
No active recalls currently cover electrical issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
