Genesis service campaign L03G
Genesis filed this with NHTSA as a service campaign dated Feb 18, 2026, received Feb 24, 2026, about the electrical system — 2 documents under this number: 26-01-017G DCS, 26-01-017G TSB.

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
Source: NHTSA's summary of the manufacturer's communicationCertain GV70 (JK1A) vehicles may exhibit a Data Communication Unit (DCU) software error due to the internal timer initialization logic not being implemented. The DCU module may shut down telematics services after one year. Technical Service Bulletin (TSB) 26-01-017G provides instructions to perform the software update for the DCU module.

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 L03G 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 L03G 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 L03G cover?
The manufacturer filed it against 1 model year: 2026 Genesis GV70. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
