Misfire on other Odyssey years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2020, 2021, 2022, 2023, 2024, 2025, 2026.
What this problem usually is
These reports start with the check engine light. Many describe the engine running rough or shaking at idle, a P0300-series code, or a catalytic converter code. A worrying number say the light was flashing. Owners often list ignition coils or spark plugs already replaced, and the light coming back afterward.
What got replaced
Owners who name the part that was replaced mention the spark plugs (17 reports) and the ignition coils (4 reports).
Recalls and investigations
2 recalls on the engine cover the 2015 model year. A recall on the same system isn't always the same failure, so read the defect text.
The fuel pump inside the fuel tank may fail.
The affected vehicles have fuel tanks that were manufactured with insufficient welds which may separate and allow fuel to leak out.

Is this a known problem?
The manufacturer has sent NHTSA 4 service bulletins or notices for the 2015 Honda Odyssey that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

What owners wrote
“American Honda Motor Co, Inc. recently sent a warranty extension due to piston ring deterioration causing misfires. They have improperly denied my claim for reasons that were clearly arbitrary and to get out of reimbursing me for the repair. This is a safety concern because the car is unable to accelerate safely to merge onto an interstate and puts other drivers at risk.”

When I first went in for a first service my car have a light saying Check engine, check VSA, check LDW, check FDW and once a while my shake when we are on the road. We told the service people at the dealership to have a look at it but they said nothing wrong with it.”

“Cylinders misfire due to leaky cylinder rings. Causes car to ride rough / shake violently. Needs to replace spark plugs, which were completely fouled out with oil. We have needed to have this car towed multiple times and make repeat repairs.”

“Piston rings in cylinders 1-3 failed and allow oil to foul spark plugs and causes misfires. Same issue they have on the older models and subject to class action suit. TSB has been released, but repair charge for this continued design flaw estimated over $4000. 140,791 miles, services maintained. A search of the Honda blogs show this to be a continuing issue for many owners.”

Should you keep driving it?
This page can't tell you that. 0 of 27 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
