Mike,
I haven't had much experience with the service department. I've only had my Mazda3 in for a recall relating to some airbag component. It was just a 15 minute check for possible cracks in a sensor housing. The only other problem I've had was squealy brakes, which I heard there may be a TSB for but they claimed it was normal and I didn't argue (the VIN range I saw didn't match mine); so I figured it was easier to put some $5 anti-squeal compound on the back of the pads myself. So, I can't really say too much about their service department.
