That manager is full of it. I would take the car to another dealership. That is certainly not normal, they'll tell you anything so they don't have to diagnose your issue. I have experienced that scenario before at a Lexus dealership and went to another place because i knew the issue I had was legitimate. Second place ended up swapping out spark plugs and injectors which fixed the issue I had with the car going into limp mode. Not all dealers are created equal, some have very poor customer service so the consumer must be willing to find another dealership who will take his/her concerns seriously.
