Common questions
Source: NHTSA, 49 CFR 579.5Is Jaguar Land Rover H506/N908 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 H506/N908 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 H506/N908 cover?
The manufacturer filed it against 7 model years across 2 brands (Land Rover and Jaguar): 2025 Jaguar F-Pace, 2024 Jaguar F-Pace, 2025 Land Rover Defender, 2024 Land Rover Defender, 2025 Land Rover Discovery, 2024 Land Rover Discovery and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
