Mopar Dealer Service Department - Am I Correct To Be Pissed Off???

Anytime i have had anything to do with those cable type regulators,patching them always results in a comeback. The aftermarket ones seem to work just fine.
Im suprised dealer charges 185 to check it out,most regulators take about 1 hour to replace. But they apply it to the repair.
Dealer shop rates now are insane,and they add 15% to 20% surcharges on top of their hourly. Oe parts have always been outrageous.
