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 6 model years this bulletin names have filed 2,897 complaints with NHTSA since 2015. 479 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.
On the 2018 Honda Odyssey, the 41 owners who gave an odometer reading for Engine reported it at a median of 93,533 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Car has under 7000 miles. Engine struggles with power in lower gears. There is also a jump when shifting from reverse to forward. The jump feel like a transmission gear transfer issue. Today as an example, when departing from a traffic light, I had to fully compress the gas pedal to get the engine to respond.

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.
