Thanks Joseph, you’re probably right, this is one of those mileage based reminders. I always look in the manual first, but I think we all know how incomplete those are! Taking it in for a tune up next week anyway. I have a great relationship with my dealer..they’ve had opportunities in the past to soak me, and they never have, so I trust them. In the meantime, I will unplug it and let it reset. I’d bet good money that will put it back to normal!
