Jaguar filed this with NHTSA as a manufacturer communication dated May 9, 2025, received May 14, 2025, about the engine. It names 2 model years (2023–2024). 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.

Source: NHTSA, 49 CFR 579.5Is Jaguar TUCC_MAY2025_19 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 TUCC_MAY2025_19 repair free?

Which vehicles does TUCC_MAY2025_19 cover?
