Land Rover bulletin SFCC_DEC2020_29
Land Rover filed this with NHTSA as a service bulletin dated Dec 16, 2020, received Jan 9, 2021, about the power train. It names 17 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

On the 2017 Land Rover Range Rover, the 14 owners who gave an odometer reading for Engine reported it at a median of 22,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
