I agree with @VOLVO_V70. Your daughter should take the car back to the dealer and tell them that their fix didn’t work. She doesn’t have to tell them anything about what went on at Pep Boys.
While we’re on the subject of Pep Boys. They can do good work, it really depends on the shop. They don’t pay well, so you might expect younger, less experienced mechanics to work there. If the shop foreman isn’t the best, shop diagnoses and work done can suffer.
