What owners reported
Source: NHTSA complaint databaseOwners of the 151 model years this bulletin names have filed 21,979 complaints with NHTSA since 2015. 268 of them name Exterior Lighting — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
On the 2016 Hyundai Sonata, the 23 owners who gave an odometer reading for Exterior Lighting reported it at a median of 53,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

On one of the occasions, the top break light in my trunk apparently blew out without my knowledge, it wasn't until my two kids in the backseat started to smell smoke that I pulled over and…

Common questions
Source: NHTSA, 49 CFR 579.5Is Hyundai 25-BD-012H 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 25-BD-012H 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 25-BD-012H cover?
The manufacturer filed it against 164 model years across 2 brands (Hyundai and Genesis): 2026 Genesis G70, 2025 Genesis G70, 2024 Genesis G70, 2023 Genesis G70, 2022 Genesis G70, 2021 Genesis G70 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
