What it saysDamage/marking may be evident on the surface of the Instrument Cluster (IPC) lens. NHTSA’s full summary ↓
Land Rover filed this with NHTSA as a service bulletin dated Dec 4, 2020, received Jan 8, 2021, about the electrical system. It names 13 model years (2016–2021). 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 owners reported
Source: NHTSA complaint databaseOwners of the 13 model years this bulletin names have filed 1,128 complaints with NHTSA since 2015. 244 of them name Electrical System — 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.
On the 2020 Land Rover Range Rover, the 13 owners who gave an odometer reading for Electrical System reported it at a median of 14,690 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Land Rover LTB00766NAS5 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 LTB00766NAS5 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 LTB00766NAS5 cover?
The manufacturer filed it against 13 model years: 2021 Land Rover Discovery, 2020 Land Rover Discovery, 2019 Land Rover Discovery, 2018 Land Rover Discovery, 2017 Land Rover Discovery, 2016 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.
