I own a 2007 lincoln mkz with michelin energy mxv4 tires dot number b90a nnhx 0207 which are original equipment on the vehicle. during normal operation in the last 6 months i have experienced valve stem failures on 3 of the 4 original tires leading to a severe air leak and in two instances damage to the sidewall of the tire. in each case the damage was repaired by replacing the tire and/or valve stem at a lincoln dealership. the dealer, ford motor company, and michelin refuse to acknowledge that there is a problem. *tr
