I have encountered on three different occasions the sensored tire valves failing and leaking. I reported the first to Toyota and the dealership replaced the faulty valve. Approximately 2 months later I had a second valve fail and again had it replaced at a Toyota dealership. On June 25, 2012 I again had a valve failure and contacted the Toyota customer care center thinking I had a design problem as three of the four valves failed within 6 months. I was told that they would replace any valve deemed defective but not replace all four as I requested. My concern is that with these valves a failure could occur at any time and at highway speeds this could be tragic. I am asking that this Agency look into the valve design and failure rate to determine if the public safety is at risk. I have replaced all the valves with standard rubber valves making my pressure monitoring system inoperable. Toyota will make no attempt to rectify this situation to my satisfaction and I am truly concerned that a potential problem truly exists. I am sure that my pickup truck is not the only one with this type of failure rate.
