Genesis service campaign T73G
Genesis filed this with NHTSA as a service campaign dated Jan 30, 2026, received Sep 3, 2025, about the electrical system — 2 documents under this number: 26-01-012G TSB, 25-01-057G TSB. It names 2 model years (2025–2026). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.
What the bulletin says

The DCU module may shut down telematics services after one year. This bulletin provides instructions to perform a software update for the DCU module.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Genesis T73G a recall?
No. A service campaign 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 T73G repair free?
A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does T73G cover?
The manufacturer filed it against 2 model years: 2026 Genesis G80, 2025 Genesis G80. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
