Land Rover bulletin N892v3 - 01MAY26
Land Rover filed this with NHTSA as a service bulletin dated May 1, 2026, received Jun 3, 2026, about the engine. It names 20 model years (2020–2026). 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.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationArduous customer drive cycles have been found to accelerate the degradation of engine oil, leading to generation of engine oil sludge deposits in high pressure engine oil galleries of the engine and inside the Continuous Variable Valve Lift (CVVL) unit.

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 Land Rover N892v3 - 01MAY26 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 N892v3 - 01MAY26 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 N892v3 - 01MAY26 cover?
The manufacturer filed it against 20 model years: 2026 Land Rover Defender, 2025 Land Rover Defender, 2024 Land Rover Defender, 2023 Land Rover Defender, 2022 Land Rover Defender, 2021 Land Rover Defender and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
