Hello 👋🏻
I have a 22’ XC90 T8 (6k miles). Within the last months I’ve had my check engine light turn on 3 times. When I pull the error codes myself, I get
P0300- Random/Multiple Cylinder - Misfire detected. Dealer gets same code ECM-030092. Seems to happy going from hybrid to gas during warm up

Any idea what’s going on?


Summary from dealer investigation
1st try: dealer pulled the codes, pushed a software update and all was fine
2nd try: dealer said there were some iffy spark plugs and replaced
