Genesis warranty extension L09G
Genesis filed this with NHTSA as a warranty extension dated Jun 3, 2026, received Jun 16, 2026, about the unknown or other — 2 documents under this number: 26-01-049G DCS, 26-01-049G TSB. It names 2 model years (2026). A warranty extension 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 G80 (RG3) and G90 (RS4) vehicles equipped with the 2.5T‑GDI Theta III or 3.5T‑GDI Lambda III engine may experience reduced air‑conditioning performance due to a refrigerant leak originating at the Thermostatic Expansion Valve (TXV). This condition may be caused by improper installation of the liquid and suction pipe O‑rings at the TXV connection point. Technical Service Bulletin (TSB) 26-01-049G provides instructions to replace the TXV O‑rings at the liquid and suction pipe connections to correct the condition.

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 L09G a recall?
No. A warranty extension 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 L09G repair free?
A warranty extension 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 L09G cover?
The manufacturer filed it against 2 model years: 2026 Genesis G80, 2026 Genesis G90. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
