Land Rover bulletin TUCC_MAY2026_04
Land Rover filed this with NHTSA as a manufacturer communication dated May 15, 2026, received Jun 3, 2026, about the unknown or other. It names 6 model years (2025–2026). A manufacturer communication 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.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5; the full text comes from the manufacturer or a dealer. 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. Quote it at a service desk; it is what the dealer’s system is keyed on.

Common questions
Source: NHTSA, 49 CFR 579.5Is Land Rover TUCC_MAY2026_04 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 TUCC_MAY2026_04 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 TUCC_MAY2026_04 cover?
The manufacturer filed it against 6 model years: 2026 Land Rover Defender, 2025 Land Rover Defender, 2026 Land Rover Discovery, 2025 Land Rover Discovery, 2026 Land Rover Range Rover, 2025 Land Rover Range Rover. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
