Well, on Monday evening I finally got a recall letter for the Takata shrapnel airbag. It included this line, bold and underlined: Until the repair is performed, the front passeger seat should NOT be occupied.
I expected a real hassle after reading about this recall over the past few years, but it couldn't have gone more smoothly.
I called on Tuesday morning. The dealership said they had one part left in stock, and scheduled me for Wednesday morning. It took a couple hours longer than expected because they had to chase down another part, but I can now ride with my wife and not fear the airbag inflator exploding. The ticket says they replaced the airbag and a retainer.
I hope everyone else's recall goes this well as the campaign works its way to the end.
