No Extended Warranty

I had to take my truck to the shop on 2/2/13 due to an ongoing concern about my brakes. The brakes were not stopping as good as normal and the truck was starting to cut off when left idling for short periods of time.  The dealership called me on 2/4/13 and told me they discovered the cause of my issue.  My service specialist went on to tell me that it would cost $600 for the repair because that particular part was not covered by the extended warranty.  So my truck that I have had just over a year, put a $600 dent in my pocket.  Guess you can't put a price on safety.   And I guess you can't argue if there is no extended warranty.
