What owners reported
Source: NHTSA complaint databaseOwners of the 15 model years this bulletin names have filed 733 complaints with NHTSA since 2015. 4 of them name Suspension — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
The safety defect remains unresolved, and my vehicle has been out of service since March 2026. Despite repeated attempts to obtain repairs, the manufacturer has been unable to provide the necessary replacement parts, leaving the vehicle unusable for an extended period of time.

Common questions
Source: NHTSA, 49 CFR 579.5Is Land Rover SSM76143 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 SSM76143 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 SSM76143 cover?
The manufacturer filed it against 15 model years: 2024 Land Rover Defender, 2023 Land Rover Defender, 2022 Land Rover Defender, 2021 Land Rover Defender, 2020 Land Rover Defender, 2024 Land Rover Discovery and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
