What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 514 complaints with NHTSA since 2015. 260 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 2025 Honda Odyssey, the 14 owners who gave an odometer reading for Electrical System reported it at a median of 16,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Sitting at a light, the auto stop system activated and shut the engine off. When the light turned green, I took my foot off the brake and the engine failed to. Start and the entire electrical system shut off. The card was completely dead. I sat there for several minutes and I was able to restart the car
