Read by machine from the document NHTSA serves (13 pages), read Sep 30, 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.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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.

After the Ford recall software update, the gear shifter will turn itself out of park and either into drive or reverse. The software update was in regards to the PCM resetting itself. We took it to the Ford dealer and because they can not duplicate the problem, the truck was returned to us.

Purchased this truck new and took on a trip over the weekend. Put on just under 800 miles no issues. This morning while driving to get my wondows tinted I noticed my truck flashing to apply brakes as it was trying to shift itself into 4wd low setting.

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 26B08 a recall?
No. A manufacturer communication 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 26B08 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 26B08 cover?
The manufacturer filed it against 6 model years across 2 brands (Ford and Lincoln): 2025 Ford Bronco, 2026 Ford Explorer, 2025 Ford Explorer, 2025 Ford Ranger, 2026 Lincoln Aviator, 2025 Lincoln Aviator. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
