NHTSA Complaint #11622633 — 2018 HONDA ACCORD

I have a 2018 1.5 Touring with 94k (bought 5 years ago with 7k miles. Religiously performed all maintenance including oil changes and transmission fluid. I started having this issue on and off about 2k miles ago. This is an intermittent problem. Sometimes the car runs great with no problem...then the next time I start the car there is a rough idle and I get the shuttering/jolting/jerkiness (feels like the engine is misfiring) when the engine revs over 2.5k rpms or so. Out of habit, I typically drive in eco mode as I drive mostly highway miles. I also noticed that this is less of an issue in sport mode. If the jerkiness starts, keeping the car under 2k rpms avoids any additional jerkiness. If I accelerate, I will get one of two results: - The first is limp mode, which I can solve by pulling over, turning the car off, turn the car back on and the check engine light goes away...and the car may or may not be jerky again. - The second is limp mode with a Christmas tree of lights on the dash and warnings in the tachometer display area - which cycles through the following system problems: "Brake System", "Vehicle Stab Assist", "Hill Start Assist", "Adaptive Cruise C System", "Collision Mit Braking System", "Road Departure Mit System", "Emission System", "Electronic PS System ". If I turn the car off and back on, the error lights and messages still appear. I can clean the codes (P0302 cylinder #2 misfire) with my scanner, then the messages and lights go way...and the car may or may not be jerky again. I took the car to an experience independent shop that works primarily on Hondas. My mechanic had not seen this issue before. He test drove it and (luckily) experienced the issue. I asked him to install the new spark plugs that I bought from Honda. He also swapped coil packs around and had the same issue. He pulled the codes before and after the new plugs and swapping the coil packs around and the code was still on Cylinder #2.
