Jaguar Land Rover filed this with NHTSA as a service bulletin dated Apr 28, 2026, received May 6, 2026. It names 7 model years across Land Rover and Jaguar (2025–2027). 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Jaguar Land Rover E004 v1 - 28APR26 a recall?
No. A service bulletin 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 E004 v1 - 28APR26 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 E004 v1 - 28APR26 cover?
The manufacturer filed it against 7 model years across 2 brands (Land Rover and Jaguar): 2026 Jaguar F-Pace, 2026 Land Rover Defender, 2026 Land Rover Discovery, 2025 Land Rover Discovery, 2027 Land Rover Range Rover, 2026 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.
