Mitsubishi filed this with NHTSA as a service bulletin dated Feb 12, 2026, received Feb 7, 2023, about the visibility/wiper — 2 documents under this number. It names 11 model years (2016–2022). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

Read by machine from the document NHTSA serves (2 pages), read Sep 30, 2026. A part number is shown only where it matches Mitsubishi’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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mitsubishi TSB-23-55-001 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-23-55-001 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. Every Mitsubishi warranty extension on file lists the ones Mitsubishi has filed.
Which vehicles does TSB-23-55-001 cover?
The manufacturer filed it against 11 model years: 2022 Mitsubishi Eclipse Cross, 2020 Mitsubishi Eclipse Cross, 2019 Mitsubishi Eclipse Cross, 2018 Mitsubishi Eclipse Cross, 2022 Mitsubishi Outlander, 2021 Mitsubishi Outlander and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
