It appears they want to check/fix all of them, whether or not they've had prior repair, in what could be an excess of caution due to election years and congresscritters wanting to be on prime time. You'd think they'd do the upgrade on any future repair to save some money and owner aggravation.
Shows what the search is good for (looked for 14v-391 & nada). Thought the video was about a year ago. Oh well dealer hasn't gotten the recall kit for my brake booster in yet, will have them check when in.
I got mine yesterday and it said to contact the dealer, but not before Sept 15, to schedule my visit. I guess they want to give enough time for them to get repair parts in. Any bets on whether I go in and they have to order the parts. Probably shouldn't go in until the parts for my JGC are in. We'll see.
