Ford Hybrid Pedestrian-Alert Recall: 26S51 Remedy Update

Recall Update

Updated October 16, 2026

Ford recall 26S51 covers certain Explorer Hybrid and Lincoln Nautilus Hybrid SUVs whose pedestrian warning sound can stop working. The current NHTSA record describes a phased software remedy, plus an additional module replacement for some Nautilus vehicles. It also confirms that owner letters were mailed August 7, 2026, updating the earlier announcement’s repair and notification information.

Which vehicles are included?

The manufacturer’s June 30 filing identifies hybrid vehicles with the Phoenix Audio System. The campaign’s 66,383 potentially affected vehicles are divided between two model groups. That number describes the recall population; it is not a count of vehicles that have experienced a loss of sound.

The model name and year narrow the search, but do not establish whether a particular SUV is included. Ford says these vehicles were not produced in VIN order. A matching exterior, hybrid badge or audio-system description cannot substitute for checking the vehicle’s identification number.

Why an audio-system problem is a safety recall

The filing describes intermittent loss of the pedestrian alert while the vehicle is moving in electric mode below 30 km/h, approximately 19 mph. Without that sound, a pedestrian may have more difficulty recognizing that a vehicle is approaching. This is an exterior warning function, rather than simply a problem playing music through the cabin speakers.

Ford says the driver may see “Pedestrian Sounder Fault. Service Now” in the instrument display. The condition can occur without driver input. The filing’s description of an intermittent fault is also why a quiet driveway observation or an absent message cannot establish that the recall has been resolved.

What has changed since the initial announcement?

The original filing said additional remedy actions were under development and forecast interim letters for August 3–7. The NHTSA campaign record checked October 16, 2026 describes an over-the-air update or a dealer update to the Accessory Protocol Interface Module software, free of charge. Nautilus Hybrid vehicles with the 28-speaker system additionally need the digital signal processing module replaced.

NHTSA calls this a phased campaign: remedy availability depends on the model and model year. The campaign-wide description therefore does not establish that an update is currently offered to every vehicle. Owners need the instructions and available remedy for their VIN, including whether the additional Nautilus hardware work applies.

An earlier recall repair is a separate question

This campaign expands recall 25V691. NHTSA specifically says vehicles previously repaired under that recall must receive the new remedy. An old software-update receipt should therefore be checked for the campaign number, rather than treated as proof that 26S51 is complete.

Use the NHTSA VIN lookup and the latest manufacturer notice, then ask Ford or Lincoln to confirm the applicable phase and completion record. NHTSA’s lookup shows unrepaired safety recalls; a general year-and-model search serves a different purpose. Ford lists customer service at 1-866-436-7332. When reviewing repair paperwork, match the VIN and 26S51 campaign identifier, and check whether the record covers all work required for that vehicle.
