It was bought in 2011, and ever since me and my wife are so sick in tired of buying and buying and buying these valve stems that are junk and it looks like 15 dollars to buy but its 60$ to put in. . This is garbage completely useless. . You fill the tire up and you can hear the air come out of it its like a every couple of months I've had to buy one now I think its time to say something this should be a recall to put regular old fashioned valve stems and take them tpms out of the cars/trucks some people cant afford these things every couple of months.
2007 Chevrolet Trailblazer. Consumer writes in regards to valve stem caps and tire pressure the consumer stated while driving, an icon on the dashboard lit up and indicated low tire pressure. The consumer stopped to a gas station to check the air, but was unable to unscrew the valve stem. When the consumer arrived home, he had to use a small box wrench in order to get a better grip on the cap. It turned a little and then all of a sudden, the valve cap broke off the tire. The tire then deflated and the consumer was forced to put on the spare tire. He was unable to screw the valve cap back on the stem. The consumer took the vehicle to the dealer, where he was informed the valve stem cap was corroded due to the salt used on the roads in the northern part of wisconsin. The dealer stated the part was defective and it was a bad design. The dealer stated they would not pay for the replacement valve stem. The consumer went to an independent mechanic and had the valve replaced at a cost of $87. 00 the consumer stated the another valve stem broke.
