Problems with 2009 Volvo XC70 TIRES

Tire pressure monitoring system catastrophic failure. while checking the tire air pressure routinely, two separate tire valves broke off and the tires went flat immediately. volvo refused to cover the repair ($100 per valve and pressure monitoring sensor). i replaced all 4 at local tire shop. this is a dangerous and possibly life threatening problem. what if the valves broke off while i was on the highway? to add insult to injury, the replacement parts (volvo # 31302096 made in france) are exactly the same and have no corrosion resistance or rubber covering to protect them. volvo should be made to recall all of these wheels and tire pressure monitoring valve stems and sensors and replace them with corrosion resistant units. *tr

Tire pressure monitoring system failed. on two separate occasions (4/14/14 and 8/25/14) low pressure light came on. when checking tire pressure, the stems disintegrated. tires went flat. replaced flat tire with spare and drove to local tire shop. the tire service mechanic told us the replacement part is the exact same part that corroded initially. called volvo with no satisfactory response. said it was not on any recall list. informed them of my concerns for a potentially catastrophic situation. after researching the problem, found there are other complaints about this tpms senor. why no recall? *tr
