2009 Mazda MAZDA5 Tires Problems

“Tpms sensor-valve failure: I was driving to work going about 40 MPH when TPMS light went on. I could not pull off immediately because of road conditions. Shortly after that I could hear the sound of a very flat tire. When I managed to pull off and check the tires, one was completely flat. Tire was too damaged to re-inflate. The relatively new tire and the TPMS sensor had to be replaced.”

“The tire pressure sensor illuminated and I checked to see if the tire was flat. It was not. I drove to a filling station to top off the pressure and as I was driving away from the air pump the valve stem to the rear driver side tire broke and the tire deflated instantly. The valve stem was corroded. Apparently it was initially cracked slightly causing the tire to first lose air slowly. Then, upon manipulation from the pump fitting, the stem was further damaged causing the stem to break off. I did have this happen once before. The explanation from a service station was the same. …”

“Valve stem broke off while low filling tire with air. Each time the tire looked a little low and when air nozzle was used it broke off and flew forcefully and all the air came suddenly rushing out. The computer low tire light was on the first time this happened, that is why I checked the pressure. I had to call service both times and had them changed tire and replace valve stem with non-computerized kind. They did not find any reasons that the tires had gone low other than the valve stem may have been already leaking. …”

“At about 30,000 miles, I noticed considerable vibration and a thumping noise, particularly prominent in the right front quadrant. When the dealership checked the problem it was diagnosed as uneven tire wear on the front tires and I purchased two new tires and had an alignment performed. The problem recurred within 10,000 miles, after the next service. Once again the diagnosis was uneven tire wear, this time on the set of tires which had not been replaced. The dealer indicated that they needed to be replaced as they were a safety risk. …”

“Tpms sensor-valve slow leak: four new tires (pirelli p6 four seasons) installed at Mazda dealer on jan 2011. The original TPMS sensor-valves where used on the new tires. After that the TPMS warning light would go on every couple of weeks. I would check the pressure in all the tires using a digital gauge which showed slightly low pressure (high 20?s PSI) in one tire, the same tire each time. I would inflate the tire to the correct pressure. One reason I am reporting this is that there is a well-documented history of TPMS sensor valves breaking easily when putting air in the tire. …”
