What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 12 complaints with NHTSA since 2015. 5 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 the vehicle was in motion, it became unresponsive and lost power, creating an extremely dangerous situation for us and other motorists. It started signaling a hybrid power failure, then power steering wheel failure, then ABS until it stopped working while in motion

A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
