Land Rover bulletin SSM76492 - 20AUG26
Land Rover filed this with NHTSA as a manufacturer communication dated Aug 21, 2026, received Sep 8, 2026, about the unknown or other. It names 19 model years (2020–2026). 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Land Rover SSM76492 - 20AUG26 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 SSM76492 - 20AUG26 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 SSM76492 - 20AUG26 cover?
The manufacturer filed it against 19 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.
