Traveling on 3 lane highway at 65 mph with 2 young granddaughters in car right front valve stem blew out causing car to veer to right. upon inspection by mechanic 2 more valve stems had cracked nuts. had to replace all stems, 1 sensor and 1 tire. dealership refuses to accept responsibility even tho their tech admits there is a design flaw in the stem. i called schrader electronics (the manf.) they also admit there is a design flaw but because it is eom product i must deal with chrysler. they also refuse to accept any responsibility. this is a very dangerous problem that most people are not even aware of. why hasn't your agency addressed this problem to date? it has cost me nearly $400.00 in unreimbursed repairs. *tr
