Audi filed this with NHTSA as a service bulletin dated Dec 1, 2023, received Jan 4, 2024, about the seat belts. It names 50 model years (2019–2024).

Quoting the number at a service desk can save a diagnosis.

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 50 model years this bulletin names have filed 787 complaints with NHTSA since 2015. 597 of them name Electrical System, Engine, Fuel/Propulsion System — 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.
On the 2020 Audi Q3, the 18 owners who gave an odometer reading for Engine reported it at a median of 2,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

Problem had been known on hybrid models of Audi specially larger models. Recall/TSB have been opened for those vehicles. Vehicle was inspected by dealership. No prior warning other than that immediate red warning

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 Audi AVIN4PIN20231201 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 AVIN4PIN20231201 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 AVIN4PIN20231201 cover?
The manufacturer filed it against 50 model years: 2024 Audi A3, 2023 Audi A3, 2024 Audi A5, 2023 Audi A5, 2024 Audi A6, 2023 Audi A6 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
