So mine failed a couple of months ago. only 26k on it. i asked them if i got my own csc if they would install it under warranty. they said no
i talked to them about others having the same problems even with newer cars and said i didn't want the same cheap part. the only thing they could tell me is it had a new part # and that usually means something changed. maybe they upgraded it? i had no choice i had to let them fix it. i just couldn't afford to not have it fixed under warranty.
