Land Rover filed this with NHTSA as a manufacturer communication dated Nov 15, 2024, received Dec 5, 2024, about the electrical system. It names 3 model years (2020–2022). 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.

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.

What owners reported
Source: NHTSA complaint databaseOwners of the 3 model years this bulletin names have filed 178 complaints with NHTSA since 2015. 47 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.
Engine light came on while at a stop light, engine faltered completely and car stalled. Would not restart. Shifted car into Park and tried multiple times to restart, finally got it restarted. Rolled forward per the flow of traffic and engine died again in the middle of the intersection putting me directly in harm’s way.
