Read by machine from the document NHTSA serves (1 page), read Sep 30, 2026. A part number is shown only where it matches Audi’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. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 29 model years this bulletin names have filed 249 complaints with NHTSA since 2015. 134 of them name Electrical 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.
BSG/alternator faulty. Started displaying “electrical malfunction!” Had to stop immediately before immediate shut down on road. 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Audi SM 24-2026 a recall?
No. A manufacturer communication 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 SM 24-2026 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 SM 24-2026 cover?
The manufacturer filed it against 31 model years: 2026 Audi A3, 2025 Audi A3, 2024 Audi A3, 2023 Audi A3, 2022 Audi A3, 2026 Audi A5 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
