I came across this older thread and wanted to share my experience:
— I just got a 2018 Kia Soul EV+ and it’s making high frequency pitching noise all the time the vehicle is on.
— While test driving, I was wearing a hat which was covering my ears and couldn’t hear that tinnitus style noise...
I just got a brand new 2018 Soul EV+ and it’s making this high pitching sound. It’s coming from the instrument cluster. It’s driving me crazy. I am going to take it back to the dealer. Has anyone been able to root cause this?
