Just under 100K transmission is intermittenly slipping when shifting into a higher gear(usually at lower speeds)
If you are the original owner, it may still be under warranty. Get it to a dealer right away. If you are the 2nd owner, get it into a good independent transmission shop. If the trans fluid has never been changed, that lack of maintenance may have just reared its head.
I don’t know about 2010, but on the new ones the warranty is transferable, but a transferred warranty might have different terms. It’s worth checking out though.
