In owners’ own words
Source: NHTSA complaint databaseFiled with NHTSA by the people who own these cars, about the engine. Quoted as written, with anything identifying removed; unverified reports — what was said, not a finding that it was true.
Vehicle shut down and failed to start at stoplight. It was as of it shifted off or in to neutral. Battery light showed red when initially tried to restart. Finally engine started after tuning off and back on again. I believe it was a failure of the auto engine stop system currently under investigation.
My Pilot has approximately 25,000 miles. I was stopped at a red light, my vehicle has the ignition shut off feature, which engaged while I was stopped. When the light changed and I went to accelerate, instead of the engine restarting, the entire car stalled and would not restart.
Incident happened 3 times in 1 week (June 8th, 11th, & 15). When stopped at a light or in traffic the car shuts down. The engine does not restart when it's supposed to, leaving us with a dead vehicle. The car had to be jump-started to get the vehicle moving again. In worst cases, the battery doesn’t even hold a charge.
Start/Stop function engaged at a red light, stopping the engine. Engine would not restart. Car and driver were stranded in the middle of a busy intersection for almost 2 hours until car could be jump started. Car would not restart on its own, leading to a very dangerous situation for driver and other motorists
When engine auto-shutoff was on (as it is automatically every time the car is started) I came to a complete stop and the vehicle turned off completely. I was in the middle of the road on every occasion this occurred. The vehicle would not restart for at least 30 seconds

Common questions
Source: NHTSA complaint database, recalls and manufacturer communicationsAre engine problems common on the 2020 Honda Pilot?
They are documented: NHTSA holds 104 owner complaints naming the engine on this model year (21% of everything owners filed about it), and 28 manufacturer bulletins, 4 NHTSA investigations are filed under the same heading. Whether it is a problem on one particular car is a diagnosis, not a count, and a count says nothing about how many were sold.
Is there a recall for the engine on the 2020 Honda Pilot?
No recall campaign is filed under this heading for this model year (there are 11 filed under other headings). A bulletin is not a recall: it carries no federal duty to repair for free.
When do engine problems show up on the 2020 Honda Pilot?
Too few of the complaints carry an odometer reading to say. The model year's page shows the mileage curve across every system where it can.
What does NHTSA's "Engine" heading cover?
The engine and its cooling system. Owners choose the heading when they file, so it says which area of the vehicle the complaint is about, not which part failed.
