Thanks for the reply @VOLVO-V70.
It’s technically out of warranty (based on mileage) but I’ve read at least one post on a Pilot forum that there is an extended warranty (up to 80k) for transmission issues related to unpredictable acceleration and shifting delays, so I’m hoping maybe we’ll get lucky and this problem will be somehow related.
Since there are a few more posts out in the world about this as a problem specifically, I was hoping someone here might know about it and be able to provide enough info so I don’t get fleeced by the dealer service department.
