Correct. I'm sure they were handled as "goodwill" claims. Some dealers are better at going to bat for owners than others are. So, yes, results will vary from dealer to dealer. Just don't go in with high expectations or yelling "but I saw that some dealers are replacing them on the internet!". That will do more harm than good in helping your cause.
Even once a bulletin is issued, there are still dealers out there that either don't pay attention to the pipeline or can't be bothered unless you push them.
