Have not experienced the "hoot" but have experienced the hiccup. Took my MKC to the dealer this week (first service appointment) and mentioned this issue. Left it for the day; after driving the vehicle, both the technician and the service manager confirmed what I had reported.
They informed me there is a Technical Service Bulletin (TSB) out on this; it focuses, I believe, on replacing or modifying the torque converter in the transmission. They are ordering the applicable parts and will call me to bring the car back in to have this work done (they were hoping this would be next week).
Don't know the TSB number, but if/when I get it I'll post it back here on the forum.
