You can imagine my surprise of the failure and failure on close on top.
I personally wouldn't deactivate it, as you benefit from aero and faster warmup.
What i find on the forums is that the domestic/asian forums are a much smaller % of the overall registered owners, vs. the europeans, especially the performance cars. Rare could be true, but I'm not sure the issue overall is an anomoly. the dealer was able to replace the actuator on site, and didn't give an indication that it was a rarity, quite the opposite.
hate to say, but the dealer was also not surprised when my torque converter took a crap in the explorer last year, requiring my car to be in service for 1 month while the part was in backorder. unfortunate fellow who brought in the same year explorer at the same time but with 15K more miles, and ford wouldn't cover his torque converter taking a crap.
man was he pissed when he saw me drive away in a loaner.
