What it saysPowertrain Control Module (PCM) incorrectly reports the monitor readiness status as 'not supported'. NHTSA’s full summary ↓
Jaguar filed this with NHTSA as a manufacturer communication dated Oct 19, 2024, received Nov 8, 2024, about the power train. It names 3 model years (2017–2019). 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Jaguar Jaguar_H444_XF_18OCT24 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 Jaguar_H444_XF_18OCT24 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 Jaguar_H444_XF_18OCT24 cover?
The manufacturer filed it against 3 model years: 2019 Jaguar XF, 2018 Jaguar XF, 2017 Jaguar XF. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
