We had more than 165 rated miles remaining, and we checked app and they were able to charge up the main pattery to 90% at the SC before they called us to tell us about the contactors needing to be updated.
And how were they able to do that if the contactors failed? The contactors must engage during charging. I'd be interested to see if they write anything on the invoice. Or if you can find anything out by talking to your service advisor.
