I recently had my F250 in for service to replace the EGR cooler. While they were working on this, they broke a bolt that held the EGR pipe on the manifold. They couldn't get the bolt out so they had to replace the entire manifold. I was told I was responsible for the labor and the cost of the new manifold even though they broke the bolt. To me this doesn't seem right. Is this a common practice for the customer to pay for mistakes the service department makes? If it is, then there is no incentive for the service department to be extra careful with anything they are working on if the cost always go back to the customer.
