For those that are interested, the dealer called last night. The new part is supposed to arrive early next week. I'm told I should get a firm date Monday morning and will make an appointment with service then. They say it's about a half day to fix. Salesman has offered his demo again while it's worked on.
I didn't fill out a complaint on the NTSB website yet. I admit, I'm a bit hesitant reporting my incident as a safety incident. Quality concern, absolutely, but not necessarily safety. In my case, the vehicle responded as it should. There was an error, and an alarm came up on the screen. If I had been moving, I agree this would be very different, but all three times it's occurred while stopped. I think I'll try calling NTSB and talk it through with a person (if that's possible).
For the conspiracy theorists that posted last night. Believe what you want. There's no easy way to prove myself. Pictures with newspaper dates isn't going to happen (Who even gets newspapers delivered anymore?). I've been lurking on these forums since mid summer when I began shopping for a new Explorer. Coincidentally, when my Explorer threw that first warning, I Googled the message and ended up here. Figured I'd add to the conversation since I didn't see any talk about this happening in a 2013.
