Ford & Lincoln Hybrid Pedestrian-Sound Recall: Letters Are Mailing — Most Owners Still Have No Fix

If you own a hybrid Ford Explorer or Lincoln Nautilus, check your mailbox. Ford began mailing interim owner notification letters for recall 26S51 — the pedestrian-warning-sound recall covering roughly 66,000 hybrid SUVs — the week of August 3, 2026. For a small group of vehicles, the letter points to a repair that's ready now. For most owners, it does something different: it puts you on written notice that your vehicle has a safety defect, while telling you the fix is still being developed. This article covers what the letter means, what to do with it, and when waiting on a repair becomes a California lemon law issue.

A quick refresher on the recall

Recall 26S51 covers hybrid versions of the 2025–2027 Ford Explorer and 2024–2027 Lincoln Nautilus. A software error in the audio system can randomly silence the external pedestrian warning sound — the alert a near-silent hybrid must emit at low speeds so people nearby can hear it coming. It's the second recall over this defect, expanding an earlier campaign whose fix didn't hold; even vehicles repaired under the first recall need the new remedy. We covered the recall in detail when it was announced in July.

What the letter does — and doesn't — mean

For Lincoln Nautilus models equipped with the 28-speaker audio system, dealers will replace the digital signal processing module free of charge — those owners can schedule the repair now. For every other recalled Nautilus and Explorer, the remedy remains under development, and Ford will mail a second letter once the fix is ready at dealers. Until then, the interim letter is not a repair notice. It is dated, written confirmation from the manufacturer that your vehicle has a known safety defect for which no complete repair is currently available.

What owners should do with the letter

• Keep the letter. It documents the date Ford told you about the defect and that no remedy was available for your vehicle at that time.
• Confirm your VIN at nhtsa.gov/recalls, ford.com, or lincoln.com — and if you have a 28-speaker Nautilus, schedule the free module replacement now.
• If the warning sound has actually cut out on your vehicle, tell your dealer and ask for a repair order documenting the complaint, even if no fix is available yet. A dealer visit with no remedy still creates a record.
• Save every repair order, loaner receipt, and service note, and write down dates. Repeat visits and days out of service are what a lemon law claim is built on.
• Stay especially alert for pedestrians and cyclists in parking lots, driveways, and crosswalks until your vehicle is repaired.

When waiting on a fix becomes a lemon law issue

A recall by itself doesn't make your vehicle a lemon — Ford is acknowledging the defect and promising a free fix. But California's Song-Beverly Consumer Warranty Act asks a different question: does your vehicle have a warranty-covered defect that substantially impairs its use, value, or safety, and has the manufacturer failed to fix it within a reasonable time or number of attempts? Owners in the strongest position here include those whose vehicles were already "fixed" under the first pedestrian-sound recall and now need repair again, those left waiting months for a remedy that isn't available, and those whose Explorer or Nautilus has other unresolved warranty problems on top of this one. In those situations you may be entitled to a buyback, replacement, or cash settlement, with Ford paying your attorney fees.

If your hybrid Explorer or Nautilus is caught in this recall — especially if it's been repaired once already or keeps going back to the dealer — a free case review can tell you quickly whether you have a claim worth pursuing.
