Ford filed this with NHTSA as a service bulletin dated Apr 16, 2026, received Apr 22, 2026, about the electrical system. It names 1 model year (2025).

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as the document itself states it — the build window in the manufacturer’s own words, read by machine from the PDF NHTSA serves. The build date is on the certification label in the driver’s door jamb; the dealer settles a borderline vehicle by its VIN.
Some of the vehicles listed in the Model statement above may exhibit various electrical symptoms and/or a no crank/no start condition related to an intermittent 12v battery drain. This may be due to the software in the instrument panel cluster (IPC) and/or the air conditioning control module (ACCM).

Read by machine from the document NHTSA serves (2 pages), 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.

At 3k miles the turbocharger and parts within the transmission failed on my 2025 ford maverick, there were no warning lamps or messages on the dash but I had the symptoms of lack of power, the truck struggled to climb hills, it sounded like the turbo sound was coming through the air vents, and going uphill it almost stalled.

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 26-2170 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 26-2170 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 26-2170 cover?
The manufacturer filed it against 1 model year: 2025 Ford Maverick. 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: 2025 Maverick: built on or before 9 Oct 2025; built on or before 17 Feb 2025 — the build date is on the certification label in the driver’s door jamb.
