Hyundai filed this with NHTSA as a manufacturer communication dated Nov 7, 2024, received Nov 11, 2024, about the service brakes. It names 1 model year (2025). 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 Hyundai H_EVT_20241107 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 H_EVT_20241107 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. Every Hyundai warranty extension on file lists the ones Hyundai has filed.
Which vehicles does H_EVT_20241107 cover?
The manufacturer filed it against 1 model year: 2025 Hyundai Ioniq 5. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
