I love my Edge Sport FWD - been having a problem with the Pirelli Scorpion Zero Tires - but that is now fixed with the purchase of 4 new tires (Yokohama Aztecs). Low tire sensor every other week - nitrogen put in the tires - nothing helped except getting rid of those tires. They even tried to clean the rims, put the tires in the dunk tank, you name it - my Ford Mechanic did it (and I have known him for over 20 years). Everyone who seems to be having a problem with the 22's are ALL the same problems.
