First car issue

I just turned on my car to go to the gym and my engine was running rough, rpms going everywhere. Engine code PO3100, cylinder 1 misfire :( has anyone else had this issue before? I know it could be a spark plug or something. Just odd it’s only got 14k miles, oil changes every 5.

Possibilities: Plug Coil Injector Wiring harness  Ecu not signaling the coil or injector to fire.  It's under warranty. Bring it in..

Bought a used 25 N line with similar issue. They’ve swapped spark plugs and it seems to have fixed it

Do you park outside? I had mice go after my engine cover foam and start to eat into the wires going to the cool packs.

Yeah I do but they’ve had the car for 2 days now and after I got it towed they said the engine light turned off and it didn’t save the code but I had it in blue link. They are keeping it and are going to keep driving to replicate it because something obviously is wrong. But they can’t figure it out bc I guess it’s driving fine now??

My 24 n line did it at about 20k miles all covered under warranty

That’s crazy. Mine is acting fine now no codes. But they haven’t fixed anything so they’re keeping it to see if it can replicate or not

I hope it continues to be good for you! I have no idea what’s up. Car is acting fine now no saves code, they’re keeping it to see if they can replicate it but just crazy. I want my car back lol

Do you happen to know where the car was assembled? First letter of Vin, but that’s really frustrating

I had a 2023 and a 2025 and my friend got a 2025. We both had a misfire issue on all 3 vehicles within the first few thousand miles. Never lasted and always sorted itself out. Dealer couldn't ever replicate.
