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 1 model year this bulletin names have filed 9 complaints with NHTSA since 2015. 4 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.
I was driving my car on a city street when it all of sudden stopped. The car died without warning. I was about to complete a left hand turn into a shopping center parking lot. Thankfully there was not traffic headed towards me at the time or my son and I could have been hit. There wasn't any traffic nearby behind me.

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.
