My wife has reported on several occasions that when the idle-stop feature is turned on and the vehicle has come to a stop, the engine cuts as intended but will not restart when pressure is released from the brake. Numerous lights within the instrument panel, with the exception of the check engine light, illuminate, the transmission shifts itself into neutral. The vehicle says to shift into "park", press and hold the brake and restart the vehicle using the start/stop button. I have tried to duplicate this while driving the vehicle. Yesterday, this same occurrence happened to me only I was not able to readily restart the vehicle. This latest occurrence happened in heavy traffic at a busy intersection. My wife reports having had this occur at least six to seven times, once while in traffic on the freeway. I have brought the vehicle to Honda in the past because of the vehicle jjuttering at low speeds and because of this issue. Each time I was told that because no error code was found and the issue could not be duplicated, there was nothing they could do. This issue is a potential disaster waiting to happen.
Check engine light for emissions system problem. Code p219a came up. They ended up having to replaced the fuel injectors at 25,400 miles. Our warranty is up in March. I called Honda to see if they would still fix the issue after the warranty is up. They advised that any issues would be an out of pocket expense. They are aware it is a known issue with 2016-2018 Pilots.
Check engine light indicates an emissions problem at 52000 miles. Dealership recommends fuel injector replacement although vehicle has been properly serviced at every milestone. Many other 2016-1019 Pilot owners complaining about the same issue.
