This occurred twice both happened on the highway going 65 mph. I accelerated as usual, suddenly the check engine light began blinking and I lost the ability to accelerate (limp mode). The car instantly dropped to 20 mph. After a minute, the check engine blinking light went away. Both times I was luckily able to get off of the highway going 20 mph. The first occurrence, I turned the car off for 30 minutes. After turning back on, car was fine as if nothing happened. The second occurrence, after calling Honda they recommended towing to dealership, which I did. At my dealership, they drove a lot, but could not duplicate issue. However, there was code DTC P0304 misfire. From the dealer paperwork "cylinder 4 swap spark plugs to known working plug misfire gone recommend replacing all plug random misfire. Removed and replaced all spark plugs." Since this repair two weeks ago, I have not had any issues and the acceleration feels less sluggish than before. This is a VERY serious issue that could result in injury or death if it occurs to others!
