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. 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 2 model years this bulletin names have filed 38 complaints with NHTSA since 2015. 6 of them name Service Brakes — 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.
I have noticed on my Audi Q4 in about 4 different occasions that when I applied the brakes in situations like when traffic suddenly stops, the car and wheels shakes in an uneven, irregular way. Like I never expected before in my more than 45 years driving BMW, Mitsubishi, Mazda.
