NHTSA Complaint #11555789 — 2014 HONDA ODYSSEY

I have now had a flashing check engine twice on my van. The first time it happened next to a well known national mechanic chain while in a car wash. 4 other lights came on all the sudden along with a flashing check engine light. You could feel the engine rumbling. I took it straight to the mechanic next to us and they told me I had a misfire and needed spark plugs and a ignition coil. They did that work and it did temporarily fix the problem. 6 months later the same thing happens. So I took it to a Honda dealer this time. They informed me this is actually a much larger known issue with this engine. The ring on the cylinder shifts/brakes allowing oil to come up and it ruins the spark plug, causing a misfire. They have to do a complete engine rebuild. The mechanic advised Honda knows about this issue and they see it all the time. They also warned me it is dangerous to drive the vehicle when this occurs as the engine could fail and there is a fire risk from the unburned fuel in the exhaust.
