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.

The car was at the dealership for a second time due to an emissions issue. While there the coolant light came on. After paying for a second evaluation, it was determined that the water pump was failing. Because of the water pump design, coolant migration occurred which can ultimately lead to turbo failure or catastrophic issues.

While parking the car, the gearshift got stuck in “Neutral” even though N was not pressed. I was not able to restart the car once I turned it off. Every time I pressed the start button, a warning would come on the screen “ please put the vehicle in Park. Risk of roll over”. When I pressed the park button, nothing would happen.

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 Dealer 24iO R823 a recall?

Is the Dealer 24iO R823 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.
