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 3 model years this bulletin names have filed 178 complaints with NHTSA since 2015. 17 of them name Engine — 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.
The engine cut out whilst going 90kmph on a four lane freeway. I had about 10 seconds to react before it rolled to a complete stop - it wouldn't connect the gas at all. Extremely unsafe situation, other cars beeping their horns in panic as they swerved past me. Lucky to not have caused a serious collision and die today.
