Lincoln recall 26V104 covers 4,381,878 2021-2027 Navigator, F-150, Maverick, Ranger, Expedition, E-Transit, and F-250 Sd vehicles because the integrated trailer module can lose communication while towing. The failure can cause loss of trailer brake lights, turn signals, or brake function, reducing control and visibility; the dealer repair will be free once Lincoln opens it.

What's wrong?

The integrated trailer module is the control unit that lets an affected 2021-2027 Navigator, F-150, Expedition, Ranger, Maverick, E-Transit, F-250 Sd, F-350 Sd, F-450 Sd, F-550 Sd, or F-600 Sd communicate with a connected trailer. It tells the trailer lights when to show braking or a turn signal, and on trucks with the high-series system it also helps command trailer brake function.

On affected vehicles, a software error inside that module can appear during initial power-up after the vehicle wakes from sleep. The module powers on, but it loses communication with the vehicle. If a trailer is connected when that happens, the trailer stop lamps and turn signals can stop working. On high-series systems, trailer brake function can also be lost.

Owners should see a "Trailer Brake Module Fault" message in the instrument panel before driving. The turn-signal indicator can fast flash, and a "Blind Spot Assist System fault" message can also appear.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific vehicle.

What's the safety risk?

Trailer lights or brakes that do not work reduce control of the trailer and make the trailer harder for other road users to see, increasing crash risk. Watch for a "Trailer brake module fault" message, fast flashing turn signal indicator, or "Blind Spot Assist System fault" message. Schedule the software update promptly. Repair will be free at any franchised Lincoln dealer once available.

What should I do?

  1. Check your VIN to confirm your 2021-2027 Navigator, F-450 Sd, F-550 Sd, F-600 Sd, Expedition, Ranger, Maverick, F-350 Sd, F-250 Sd, F-150, or E-Transit is included in this recall.
  2. Review the owner letter mailed on March 25, 2026 for the latest software update instructions.
  3. Contact a franchised Lincoln dealer and ask whether the free integrated trailer module software update is ready for your VIN.
  4. Reference recall number 26V104 and Ford recall 26C10 when you call.
  5. Avoid towing a trailer until the software update is complete because the trailer lights or brakes can stop working.

What happens at the repair

The final repair is still under development. Once it opens, a Lincoln technician will update the integrated trailer module software, or Lincoln will deliver the same software fix through an over the air update. The recall repair is free, with parts and labor covered when dealer work is needed. Lincoln's standard reimbursement plan covers documented out-of-pocket repairs tied to this recall. If you already paid for a related integrated trailer module repair, keep the invoice and payment record and ask Lincoln customer service how to submit the claim.

Frequently asked questions

What is recall 26V104?

Recall 26V104 covers 4,381,878 2021-2027 Lincoln and listed Ford vehicles with integrated trailer module software that can lose communication while towing. Trailer lights, turn signals, or trailer braking can stop working, increasing crash risk. The software update is free through a dealer or over the air.

What should I do if my 2021-2027 Lincoln Navigator, Expedition, Ranger, Maverick, F-Series, or E-Transit is on this recall?

Check your VIN to confirm your specific vehicle is included in recall 26V104. If it is, contact a franchised Lincoln dealer and reference Ford recall number 26C10. Ask whether your vehicle needs a dealer software update or can receive the over-the-air update.

Is the recall repair free?

Yes. Federal recall law requires the manufacturer to repair the defect at no cost. For recall 26V104, the integrated trailer module software update is free whether the fix is completed by a dealer or delivered through an over-the-air update.

Is it safe to tow with this recall open?

Use caution before towing until your VIN is checked and the software update is complete. The defect affects the trailer connection, so brake lights, turn signals, or trailer braking can stop working while towing. That reduces trailer control and visibility to other drivers.
