Engine Misfire DTC 030400, anyone have this issue with their G70?

Have a 2021 G70 2.0 that I got a few months back, less than 40k Km on it.

Was driving on the highway yesterday going a steady speed in the slow lane when all of the sudden I heard some clunking noise and felt power loss. Pulled over and turned the car off to run diagnostics. Tried to turn it back on and it wouldn't crank and the engine light came on. The app said DTC 030400 and it was an issue with the power train.

Had to get it towed to the dealership. They called me this morning and said it turned on right away and is driving normally. They didn't see any issue. Tech said the code was cleared and was a "misfire of cylinder 1" but they don't know why and it seems to be gone and they dont see anything wrong. Nothing they can do. Service rep said he has never seen this before in 5 years of working there.

Has this happened to anyone else? It makes me super anxious as it feels like it can happen again at any time without warning.
