My husband purchased a brand new 2009 Mazda5 and in February 10th 2011, as I was driving my tire lost all air, the valve had snapped in half. The dealer said I must have hit something but I know I didn't, I would have felt something if it was strong enough to break the valve, plus there was nothing on the side of the road close enough to hit the car. They made me pay $150 to replace it. In May 29th I was pumping air and it happened again on a different tire. At this time I had 37,200 miles. I called Mazda and the representative said that they never heard of this problem and it wasn't covered. I google it and there are plenty of people complaining about the same and I even saw some reports of Mazda knowing about faulty valves. I had another one break on December 15th, this was #3. this is beyond ridiculous!!! this product is definitely defective. At this point I do not want to have another one of these valves put on my tires. Mazda should recall them before someone dies on the highway when the tires go flat because of the valves. I bought this vehicle new from the dealer and had extended warranty on it, which did not cover my valves. They said I was probably pushing too hard when I was pumping air. Again, the valves should be recalled before someone dies.
