If under warranty, she might want to take it to a dealer to get checked out. They may find something and fix it for free. If not, at least it will be on record that there was a reported problem if it reoccurs down the road. (Nice pun right there) That gives her some leverage.
I've been a Mopar guy all my life, but I've had so many problems with their modern iron the last few decades that I've moved on to a more reliable brand. But I would cave in for a new generation Challenger as a part time fun car.
