Cracked Tire Valves, 2008 ford escape v6
I just saw that the government are investigating faulty tire valves, there is a recall out but it doesn't cover my vehicle. I have 2 cracked tire valve stems, someone at the dealer said if it isnt leaking air they cant replace it. Isnt this covered under warranty?? is this something to worry about? Because ive read it could cause a blowout on the freeway?
