Are repairs that are based on a TSB supposed to be fixed for free by the dealer, like warranty work? I am having trouble with my 4-wheel drive shift/indicator. THere are several TSB's associated with it that clearly state there is a design flaw in the sensor and encoder module. The TSB is 03-04-21-001D. The dealer is telling me it costs $800 to repair, even though I've had it in for the same problem several times only to be told no DTC was shown. Now all of a sudden a DTC code of CO-327 is showing up. Can anyone shed some light on what TSB's do for the customer?
THanks

 

TSB'S ARE INFORMATION ONLY. IF STILL UN 3/36 THERE FREE, BUT OTHERWISE ITS A CUSTOMER PAY EXPENSE
