Audi filed this with NHTSA as a service bulletin dated May 11, 2026, received Jun 4, 2026, about the wheels. It names 17 model years (2025–2027). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

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.

My Audi Q6 Etron has 1 year and 10,390 miles. I was informed by the dealership that tires are already showing excessive thread wear causing a safety hazard due to lack of traction. Replacement is needed. This was never disclosed by Manufacturer or dealership until last Friday during the 10,000 mile service.

Common questions
Source: NHTSA, 49 CFR 579.5Is Audi TSB_2077226_9 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 TSB_2077226_9 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.
Which vehicles does TSB_2077226_9 cover?
The manufacturer filed it against 17 model years: 2026 Audi A5, 2025 Audi A5, 2026 Audi A6, 2025 Audi A6 Sportback e-tron, 2027 Audi A6 e-tron, 2026 Audi Q5 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
