my service engine light came on about a month ago..i initially went to the dealer and they told me that there was some sort of emissions service bulletin and that everything would be free..well the light came on again..took it back said they fixed it again..came on again..said that they gave me a new cat converter..light came on the other day..took it there today and theyu said that a diff code came up from the first 3 that were all the same..need new o2 sensor(s) and that isnt covered in my 5yr/60k warranty.i just want to be sure that they are not fleecing me for something that maye be covered somehow..thanks in advance..and i am sure this has been asked before so i apologize in advance for a repost
