as others have said .. no one should be doing anything yet. The "settlement" is only proposed, it has not been accepted. It could certainly NOT happen.
Wait until they say "ok, settlement is approved. We will reimburse anyone that had it fixed, or fix it for free".
Right now they are NOT saying that. It has only been "suggested" by the CA court that we (and anyone else that is a part of the settlement group) would be interested in that settlement.
If not approved, you will be stuck paying for these dealer visits by yourself......
