| 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. *tr | |||

| 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. the more one has to inflate the tires the more likely the tpms sensor-values will break. *tr | |||

| 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. additionally the dealer indicated that the mazda 5 was hard on its rear tires (from which these had been rotated at the last service). a quick review of a variety of forums would indicate that this is a problem that others have experienced and that, in addition to the poor quality toyo tires which are original equipment, weak alloy wheels may also play a role. | |||

| While driving at 70mph on us23 in michigan, tpms low pressure telltale illuminated. within 30 secs, vehicle began to pull hard to the left. pulled off the side of this 4 lane 70mph highway in the rain to investigate. left front tire completely flat. nut holding the tpms sensor to the rim was missing & had corroded, allowing the tpms sensor to fall inside tire cavity, resulting in rapid air loss. threads of tpms sensor exhibited corrosion. drove vehicle to gmc dealership in milan mi which confirmed the tpms sensor nut failure due to corrosion. tire destroyed, rim edge chewed up. contacted mazda usa and they would not offer any consideration, stating that the 3 year warranty had expired 1 month prior, and that corrosion was not covered beyond 3 years. i stated that this isn't a cosmetic rust issue, that the corrosion resulted in a safety concern for me and my family, but mazda would not offer any resolution. the vehicle has been driven during 3 mild ohio winters; there is not any signs of corrosion anywhere else on the vehicle; i drive the car thru automatic car washes every 3 weeks or so in the winter just to wash off any road salt. no other component on the vehicle is exhibiting corrosion. had vehicle on lift to inspect the underbody. it does not seem technically sound that a vehicle component specifically mandate by nhtsa to prevent tires from being ran low in inflation pressure on a vehicle should instead cause my tire to rapidly lose all air pressure. this is a safety issue. i bought this vehicle new and know its service life. this tpms sensor was in use for only 37 months. a 3 cent nut put my family at significant safety risk. *tr | |||

| 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. i then went to dealer to get new parts, which were still under warranty, and they said it was from misuse and wouldn't do anything about it. they were very rude. said it was from hitting curb. it was not. the valve stem is well protected inside the rim. this has happened twice within the last six months. both failures were nearly identical. i did not report the first time, but after checking around i found out this has happened to others and tire repairmen said they have had to change out several. had i not seen that the tire was a little low and checked it in my garage this could have been much more devastating. i'm almost afraid to drive in case one of these would break on the road and kill me. the failures happened in december 2010 and april 2011. the vehicle i'm driving is a 2009. | |||
