What owners reported
Source: NHTSA complaint databaseOwners of the 5 model years this bulletin names have filed 3,772 complaints with NHTSA since 2015. 681 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.
On the 2018 Honda Accord, the 96 owners who gave an odometer reading for Electrical System reported it at a median of 12,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

See your dealer.", "blind spot information system problem. See your dealer.", "auto high_beam problem. Manual controls available. See your dealer.". Turn signals did not work.
