Pressure-monitoring (TPMS) fault: which tires owners report it on

THE CONTACT OWNS A 2009 NISSAN MURANO. THE CONTACT STATED THAT THE TIRE PRESSURE WARNING LIGHT REMAINED ILLUMINATED. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE TPMS SENSOR NEEDED TO BE RESET. THE VEHICLE WAS REPAIRED; HOWEVER, THE FAILURE RECURRED. THE VIN WAS EXCLUDED FROM NHTSA CAMPAIGN NUMBER: 09V393000 (TIRES). THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 125,000.

THE CONTACT OWNS A 2012 GMC TERRAIN. WHILE DRIVING 10 MPH, THE TPMS WARNING LIGHT FOR THE FRONT DRIVER SIDE TIRE. ON A LATER DATE, THE FRONT PASSENGER SIDE TPMS WARNING LIGHT ILLUMINATED. THE FAILURE RECURRED ON NUMEROUS OCCASIONS. THE VEHICLE WAS TAKEN TO A DEALER WHO MADE AN UNKNOWN ADJUSTMENT; HOWEVER, THE FAILURE PERSISTED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 10,000.

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.
