Hyundai filed this with NHTSA as a service bulletin dated Dec 20, 2024, received Dec 21, 2024, about the electrical system. It names 2 model years (2024–2025).

Quoting the number at a service desk can save a diagnosis.

Read by machine from the document NHTSA serves (3 pages), read Sep 30, 2026. A part number is shown only where it matches Hyundai’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 605 complaints with NHTSA since 2015. 155 of them name Electrical System — 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 2025 Hyundai Tucson, the 15 owners who gave an odometer reading for Electrical System reported it at a median of 5,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The contact owns a 2024 Hyundai Tucson. The contact stated that while the vehicle was parked, while attempting to enter the vehicle, the key fob failed to function as intended. The contact was unable to unlock the doors to the vehicle. The contact noticed that the battery was completely drained.

Common questions
Source: NHTSA, 49 CFR 579.5Is Hyundai 24-BE-019H 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 24-BE-019H 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 24-BE-019H cover?
The manufacturer filed it against 2 model years: 2025 Hyundai Tucson, 2024 Hyundai Tucson. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: built 2 Jun 2024 – 3 Oct 2024 — the build date is on the certification label in the driver’s door jamb.
