personally I also had terrible experience with ford and their services which make me don't want to buy another ford for the rest of my life and if I could I would dump the car just cause the services that comes with the car is so poor. (Paid in full so if I sell I lose a lot and with the market used car trade in is a pain) They tend to treat you unfair and dumb and that's 2 dealers that I gone to now. Asking for a way to reset the system is not that hard for the service manager to just call the tech guy and ask. If it doesn't work then yeah it's time to wait in the line.
My previous 2 car Nissan and BMW, whenever I had something easy like a fuse,light out, or car jump the service manager actually did the work themselves or just ask a tech guy to come look at it real fast without charge too. Since they believe in treating customer well and they will always come back for their major services.
