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.

2023 Land Rover Discovery · Electrical System · filed with NHTSA Feb 6, 2026 · ODI 11716334
On August 22, 2026 while driving my 2024 Range Rover Evoque, both passenger side tires suddenly blew out without any prior warning. The Tire Pressure Monitoring System (TPMS) failed to alert me at any point that tire pressure was low. I did not hit any road hazard or curb. The tires simply failed without warning.

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 SA Owner Letter N811 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 SA Owner Letter N811 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 SA Owner Letter N811 cover?
The manufacturer filed it against 8 model years: 2022 Land Rover Defender, 2021 Land Rover Defender, 2023 Land Rover Discovery, 2022 Land Rover Discovery, 2021 Land Rover Discovery, 2024 Land Rover Range Rover and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
