The safety recall covers certain 2021–2026 F-150, 2022–2026 Super Duty (F-250 through F-600), 2024–2026 Ranger, 2022–2026 Expedition, 2022–2026 Lincoln Navigator, 2022–2026 Maverick and 2026 Transit models. ## What’s the Problem with Ford Trailer Module Software Issue? ![Ford Trailer Module Software Issue 2]() 2026 Ford Ranger.

If the communication failure occurs while a trailer is connected, the trailer’s stop lamps and turn signals may not function. On vehicles equipped with the “High series” trailer module, the malfunction may also disable the trailer’s braking function. The condition places affected vehicles out of compliance with federal safety standards and could reduce driver control of a connected trailer while also making it less visible to surrounding traffic — increasing the risk of a crash. ## Warning Signs for Drivers ![Ford Trailer Module Software Issue 2]() 2026 Ford Transit.

Given the size of the recall — more than 4.3 million vehicles — it ranks among the larger software-related actions involving trailering systems in recent years, particularly affecting high-volume truck and SUV nameplates. ## OTA Update Begins March 17 ![Ford Trailer Module Software Issue 5]() 2026 Ford Super Duty. (Photo courtesy Ford Motor Company) The fix involves a software update to the Integrated Trailer Module. Beginning March 17, most affected vehicles will be eligible to receive the update over-the-air (OTA). Customers may also have the update performed at a dealership or through Ford’s mobile service. Ford expects OTA deployment to be completed across all affected vehicles by May. Owners can check whether their vehicle is included by entering their VIN at [NHTSA.gov/recalls]() or through the FordPass app. Ford’s internal reference number for the recall is **26C10**. ## Structured page information ~~~json [ { "@context": "https://schema.org", "@graph": [ { "@type": "Article", "@id": "https://pickuptrucktalk.com/2026/02/ford-trailer-module-software-issue-sees-4-3-million-vehicles-recalled-ota-fix-coming/#article", "isPartOf": { "@id": "https://pickuptrucktalk.com/2026/02/ford-trailer-module-software-issue-sees-4-3-million-vehicles-recalled-ota-fix-coming/" }, "author": { "name": "Tim Esterdahl", "@id": "https://pickuptrucktalk.com/#/schema/person/82b06f99329f69a069a5ab6caed18593" }, "headline": "Ford Trailer Module Software Issue Sees 4.3 Million Vehicles Recalled, OTA Fix Coming", "datePublished": "2026-02-26T20:06:50+00:00", "dateModified": "2026-02-26T20:28:27+00:00", "mainEntityOfPage": { "@id": "https://pickuptrucktalk.com/2026/02/ford-trailer-module-software-issue-sees-4-3-million-vehicles-recalled-ota-fix-coming/" }, "wordCount": 399, "commentCount": 0, "publisher": { "@id": "https://pickuptrucktalk.com/#organization" }, "image": { "@id": "https://pickuptrucktalk.com/2026/02/ford-trailer-module-software-issue-sees-4-3-million-vehicles-recalled-ota-fix-coming/#primaryimage" }, "thumbnailUrl": "https://pickuptrucktalk.com/wp-content/uploads/2026/02/24_FRD_F15_ProAccessTailgate_10_R7A7809_V1-copy.webp", "keywords": [ "ford", "ford recalls" ], "articleSection": [ "Featured on Home Page", "News", "Recalls" ], "inLanguage": "en-US", "potentialAction": [ { "@type": "CommentAction", "name": "Comment", "target": [ "https://pickuptrucktalk.com/2026/02/ford-trailer-module-software-issue-sees-4-3-million-vehicles-recalled-ota-fix-coming/#respond" ] } ] }, { "@type": "WebPage", "@id": "https://pickuptrucktalk.com/2026/02/ford-trailer-module-software-issue-sees-4-3-million-vehicles-recalled-ota-fix-coming/", "url": "https://pickuptrucktalk.com/2026/02/ford-trailer-module-software-issue-sees-4-3-million-vehicles-recalled-ota-fix-coming/", "name": "Ford Trailer Module Software Issue Sees 4.3 Million Vehicles Recalled, OTA Fix Coming", "isPartOf": { "@id": "https://pickuptrucktalk.com/#website" }, "primaryImageOfPage": { "@id": "https://pickuptrucktalk.com/2026/02/ford-trailer-module-software-issue-sees-4-3-million-vehicles-recalled-ota-fix-coming/#primaryimage" }, "image": { "@id": "https://pickuptrucktalk.com/2026/02/ford-trailer-module-software-issue-sees-4-3-million-vehicles-recalled-ota-fix-coming/#primaryimage" }, "thumbnailUrl": "https://pickuptrucktalk.com/wp-content/uploads/2026/02/24_FRD_F15_ProAccessTailgate_10_R7A7809_V1-copy.webp", "datePublished": "2026-02-26T20:06:50+00:00", "dateModified": "2026-02-26T20:28:27+00:00", "description": "A Ford trailer module software issue has the automaker recalling 4.38 million vehicles addressing a defect disabling trailer lighting.", "breadcrumb": { "@id": "https://pickuptrucktalk.com/2026/02/ford-trailer-module-software-issue-sees-4-3-million-vehicles-recalled-ota-fix-coming/#breadcrumb" }, "inLanguage": "en-US", "potentialAction": [ { "@type": "ReadAction", "target": [ "https://pickuptrucktalk.com/2026/02/ford-trailer-module-software-issue-sees-4-3-million-vehicles-recalled-ota-fix-coming/" ] } ] }, { "@type": "ImageObject", "inLanguage": "en-US", "@id": "https://pickuptrucktalk.com/2026/02/ford-trailer-module-software-issue-sees-4-3-million-vehicles-recalled-ota-fix-coming/#primaryimage", "url": "https://pickuptrucktalk.com/wp-content/uploads/2026/02/24_FRD_F15_ProAccessTailgate_10_R7A7809_V1-copy.webp", "contentUrl": "https://pickuptrucktalk.com/wp-content/uploads/2026/02/24_FRD_F15_ProAccessTailgate_10_R7A7809_V1-copy.webp", "width": 1200, "height": 800, "caption": "2026 Ford F-150.
