Ford and Lincoln vehicles equipped with wired keyless entry keypad systems and accessory wireless keyless entry keypad systems may or may not come with a wallet card containing the master code. Unlike the integrated wired keypad, the accessory wireless keypad master code cannot be retrieved from the vehicle using a diagnostic scan tool or from the label printed on the body control module (BCM). The Factory Keyless Entry Code application within the diagnostic scan tool will not provide an applicable master code for the accessory wireless keypad. If the wallet card for an accessory keypad is not available, the "Wireless RF Keypad Diagnosis Guide" can be referenced and provides direction on how

What stands out
Owners have filed 45 electrical complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
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.
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.
This article supersedes TSB 24-2165 to update the TSB Service Procedure. Some vehicles listed in the Model statement above may exhibit various SYNC performance related concerns including but not limited to: Display operation concerns Navigation inoperative Voice recognition concerns Phone connection issues Dropped phone connections Applink related performance Travel Link not present or showing incorrect traffic Slow system response NOTE: Ford has found some of the APIMs replaced and returned for inspection contained an outdated software level and the APIM did not require replacement. The customer concern may have been resolved by updating the APIM with latest level of softwar

The failure pattern owners describe
Owners describe the 2016 Focus as plagued by electrical failures that create serious safety hazards. The most dangerous pattern is sudden engine shutdown while driving—at highway speeds, traffic lights, and during turns—often without warning lights. Loss of power includes dead brakes and steering, making recovery difficult. Owners report multiple restart attempts before the car will turn over, with some vehicles staying dead until parts become available.
Transmission issues are equally troubling: shuddering, harsh shifts, jerky acceleration, and stalling. One owner spent $4,000 on private transmission repair only to have the same problem return; a dealer blamed the transmission programming but couldn't fix it. Water intrusion is a documented failure on Focus Electrics, where rain penetrates the high-voltage battery connector, yet dealerships ignore the technical service bulletin that calls for a splash shield and instead apply temporary fuses that blow immediately.
Audio system random loud popping and screeching, wiper motors that freeze mid-stroke in rain, headlight wiring that melts after replacement, body control modules that kill multiple electrical circuits, and water damage shorting out light circuits—all recur across the complaint set. Rodent-chewed wiring due to soy-based insulation costs owners hundreds in labor. A handful of owners experienced underhood fires. Many report dealers unable to diagnose the root cause, parts backordered, and vehicles excluded from recalls despite matching recall descriptions exactly.

Water intrusion into high-voltage battery connector (Focus Electric)
Rain or car wash water intrudes into high-voltage (318V) battery connector, causing electrical failure and loss of motive power. Splash shield referenced in TSB 20-2004 not installed. Dealership installed 350 amp fuse instead of addressing root cause; fuse subsequently blown.
When: During or after rain; occurs during car wash
Symptoms owners cite: Loss of motive power in rain; Red 'Stop safely now' warning message displayed; High-voltage connector exposed to water; Electrical system failure

When: At 34,600 miles and 55,000 miles reported
Symptoms owners cite: Headlamps and instrument panel inoperable; Door locks and hatch malfunction; Lights go out unexpectedly while driving; Infotainment screen freezes with loud noise; No warning prior to failure
Repairs/costs cited: BCM replacement required; Accessory Protocol Interface Module replacement also needed in one case; parts may be backordered
Recalls/TSBs owners mention: Vehicle not included in recall per manufacturer notification to owners
Wiring damage from rodent chewing
Rodents chew through vehicle wiring due to soy-based wire insulation. Damage causes electrical malfunctions and fire hazard. Repairs costly due to labor-intensive wiring replacements. Owners indicate this is a known problem Ford should have addressed.
When: Various mileage
Symptoms owners cite: Wiring damaged / chewed by rodents; Emission cable affected; Electrical system malfunction; Fire hazard; Vehicle becomes inoperable
Repairs/costs cited: One owner paid ~$500 to replace emission cable (parts only $15); labor costs high; repair required replacement of damaged sections
Headlight wiring overheat / melt

Symptoms owners cite: Headlight socket wire melts; Headlight fails to illuminate; Problem recurs after replacement; Insufficient headlight brightness
Repairs/costs cited: Headlight replaced but wire continues to melt; dealer unable to remedy in one case
Water intrusion into light wiring (hatchback)
Heavy rain or car wash causes water to enter wiring beneath taillights, shorting out multiple light circuits. Results in taillight burnout, brake light staying on, turn signals inoperative, and running lights out.
When: After heavy rain or car wash
Symptoms owners cite: Burnt wiring smell; Left taillight out; Right brake light stays on constantly; Right rear turn signal out; Left front running light out; Right front turn signal out
