Read by machine from the document NHTSA serves (1 page), read Sep 29, 2026. A part number is shown only where it matches Ford’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

My Ford Ranger is on a safety recall. They sold it to us on May 9,2025 then kept the truck. June 1 they told use the recall issue was solved. We were not given documents on this. We are now seeing the parts needed are not available until the end of June. A Fedaral and State law was broken in selling us a vehicle on a safety recall.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford TSB 26-2301 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the TSB 26-2301 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does TSB 26-2301 cover?
The manufacturer filed it against 3 model years: 2026 Ford Ranger, 2025 Ford Ranger, 2024 Ford Ranger. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: 2024-2026 Ranger: built on or before 12 Jan 2026 — the build date is on the certification label in the driver’s door jamb.
