Most techs and managers welcome warranty work. Warranty work is free for the customer, but the dealership and tech get paid by the manufacturer. However their are guidelines that have to be followed in some cases. but any route, if we (I am a Toyota tech at a Toyota dealership) can cover something under warranty, we will. Some repairs, if not covered by warranty will go unrepaired by customers so we do what we can to find ways to cover repairs under warranty so we can make the customer happy and so we can get paid. Just like everyone else, we like to get paid whether it is by the customer or by Toyota.
