Hello! I bought my first plug in hybrid today. 2024 Volvo XC60. When I charged it for the first time, I noticed that my car is making a very high pitched whirring sound under the hood. Sounds like an electrical current. I turned the charger off and removed the cable, and the whirring persisted for about a minute before turning off.

I used the charging port and cable that came with my house “Lectron Home Level 2 J1772 EV Charging Station | 240V | 32 Amp | NEMA 14-50”

I’m a total newbie and just want to be sure I’m not at risk of damaging my vehicle or home :) Thank you!
