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 2 model years this bulletin names have filed 34 complaints with NHTSA since 2015. 18 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.
While operating the vehicle under normal driving conditions, the vehicle suffered an immediate, un-commanded loss of engine power and throttle response. The vehicle displayed a critical dashboard restriction stating: “Maximum engine speed 2500 RPM”, forcing an emergency limp-home mode that instantly created a roadway collision hazard.
