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 35 model years this bulletin names have filed 739 complaints with NHTSA since 2015. 245 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.
On the 2018 Audi Q5, the 19 owners who gave an odometer reading for Electrical System reported it at a median of 48,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
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. No prior warning other than that immediate red warning

My 2023 Audi SQ5 Sportback's key fob stopped working, and when I took it into the Audi dealership they said that it is a known issue that if you don't unclog the drain (not sure where that is - was never told I needed to do so) then there can be leaks that affect the wiring and the Comfort Control Module, rendering the vehicle unusable.

Is the A5724592070128_2 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.
