What it saysCertain GV70 (JK1, JK1A), GV80 (JX1) and GV80 Coupe (JX1) vehicles may exhibit a loose windshield glass garnish seal. NHTSA’s full summary ↓
Genesis filed this with NHTSA as a service campaign dated Apr 15, 2026, received Oct 28, 2025, about the visibility/wiper — 6 documents under this number: 26-01-003G-1 DCS, 26-01-003G-1 TSB, 26-01-003G DCS, 26-01-003G TSB and 2 more. It names 3 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
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as the document itself states it — the build window in the manufacturer’s own words, read by machine from the PDF NHTSA serves. The build date is on the certification label in the driver’s door jamb; the dealer settles a borderline vehicle by its VIN.
Certain GV70 (JK1, JK1A), GV80 (JX1) and GV80 Coupe (JX1) vehicles may exhibit a loose windshield glass garnish seal. Technical Service Bulletin (TSB) 26-01-003G-1 provides instructions to remove the old garnish and install new parts.

Read by machine from the document NHTSA serves (1 page), read Sep 30, 2026. A part number is shown only where it matches Genesis’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.
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 3 model years this bulletin names have filed 59 complaints with NHTSA since 2015. 2 of them name Visibility/Wiper — 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.
Component Focus: ENGINE AND ENGINE COOLING / VISIBILITY/WIPER/DEFROSTER (HVAC) Description of Safety Defect: My brand-new 2026 Genesis GV70 Turbo (under 5,000 miles) suffered a sudden, catastrophic cooling system and heater core failure while in operation.

2025 Genesis GV80 · Visibility/Wiper · filed with NHTSA Oct 28, 2026 · ODI 11774218
A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Genesis T84G 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 T84G 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 T84G cover?
The manufacturer filed it against 3 model years: 2026 Genesis GV70, 2026 Genesis GV80, 2025 Genesis GV80. 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 15 May 2025 – 20 Aug 2025; built 4 Sep 2025 – 3 Nov 2025; built 15 May 2025 – 19 Jul 2025 — the build date is on the certification label in the driver’s door jamb.
