As more and more cars (Mazda's) become increasingly Data updated and controlled, like the current Skyactiv range of Mazda's which has about 8 times as many DTC's Diagnostic Trouble Codes over the models they replaced.
Every electrical wiring circuit and apparatus has its own DTC, so diagnostics is relatively easy and these Codes and Data file print out must be attached to any warranty claims.
Any warranty work over about $1000 must have a prior approval code from MMCs local Distributor, like MNAO, MUK, MME, MA , MNZ.
Almost impossible to rip off Mazda with bogus warranty claims which will result in Dealer Termination, I have not seen this for over 10 years.
As for the OP, there is no 'bonus' work with Mazda Warranty, if this Dealer is your selling one it is in their interest to look after you. What exactly is the or your issue?
I would change Dealers and tell the new Dealer about your issues and report them to your local Mazda Distributor.
And Yes, there is a standard flat rate per Labour hour for Warranty Work (which varies per country), which is about 50% less than normal retail work.
Virtually all work has a standard Operation Number pertaining to that particular repair, update, or recall... with a set formula of Labour Hours. Symptom Codes, Damage Codes.
A Dealer can not just charge what they want, Mazda will only pay what is set out.
Some diagnostic time can be claimed, but also can be rejected long after the customer has car returned.
In my experience Mazda is very good almost excellent.
Obviously if the mechanic or 'technician' is not terribly good and or slow, then a Dealer will wear any extra hours wasted.
Part of my beef with Mazda Dealers in North America, is there are too many who are sloppy Dealers and need culling.
A strong Dealer Network will improve new car sales and margins.
New car sales for Mazda in North America (particularly USA) has been poor with no growth for past 17 years.
