2010 Dodge Grand Caravan tires problems

“At approximately 70 MPH on the highway, a loud thumping noise was heard near the passenger rear area. Vehicle was rocking back and forth and became very unstable to drive safely. Tire pressure was checked and confirmed to be at 38 PSI. However, upon observation, the tire was shaped into a oval with a marked bulge in the tread on one side of the tire. 225/65 R16 SL”

“TL* THE CONTACT OWNS A 2010 DODGE CARAVAN. WHILE DRIVING 70 MPH, THE TIRE PRESSURE WARNING INDICATOR ILLUMINATED AND THE VEHICLE DROVE ABNORMALLY. THE CONTACT WAS ABLE TO PULL THE VEHICLE OVER SAFELY. WHEN THE CONTACT EXITED THE VEHICLE, SHE OBSERVED THAT THE FRONT PASSENGER TIRE FAILED. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE TIRE PRESSURE SENSOR, WHICH WAS CONNECTED TO THE STEM FRACTURED, AND CAUSED A FAST FLAT. THE TIRE WAS REPLACED. THE LOCAL DEALER AND MANUFACTURER WERE NOT CONTACTED. THE VEHICLE FAILURE MILEAGE WAS APPROXIMATELY 45,400. *LN CONSUMER STATED 2 TIRES HAVE LOST THE COLLARS AROUND THE VALVE STEM DUE TO CORROSION. ONE TIRE HAS COLLAR ON VALVE STEM (IT IS CRACKED) UPDATED*JB *TR”

“2010 DODGE CARAVAN. CONSUMER WRITES IN REGARDS TO VEHICLE TIRE DEFLATED SUDDENLY WHILE DRIVING AND WITHOUT WARNING. *SMD THE MECHANIC WAS UNABLE TO FIND ANY PUNCTURES, GASHES OR OTHER REASONS WHY THE TIRE WOULD HAVE DEFLATED SUDDENLY. HE CONCLUDED THAT THE NUT ON THE VALVE STEM HAD CORRODED, CRACKED OFF AND THE SEAL BETWEEN THE STEM AND THE TIRE BECAME UN-SEATED CAUSING THE MASSIVE LOSS IN AIR PRESSURE. UPON FURTHER INSPECTION, IT APPEARED THAT THE OTHER TIRES HAD CRACKED OR WERE MISSING NUTS ON THEIR VALVE STEMS AND WERE IN DANGED OF THE SAME CATASTROPHIC FAILURE. *JB”

“A LOW TIRE INDICATOR APPEARED ON THE DASHBOARD. PROCEEDED TO CHECK TIRE PRESSURE. WHILE UNSCREWING VALVE CAP FROM THE TIRE VALVE STEM THE VALVE STEM BROKE LEAVING ALL AIR OUT OF THE TIRE. NEVER HAVE EXPERIENCED ANYTHING LIKE THIS BEFORE. I TOOK THE TIRE OFF THE VEHICLE AND WENT TO THE LOCAL TIRE STORE. THE SERVICE PERSON TOLD ME THIS IS A VERY COMMON PROBLEM WITH CHRYSLER VALVE STEMS THAT HAVE THE AIR PRESSURE SENSORS. HE SAID MANY PEOPLE HAVE COMPLAINED ABOUT THIS AND THAT I WAS FORTUNATE THAT IT HAPPENED AT HOME IN MY DRIVEWAY AND NOT IN THE CAR WASH OR ON THE ROAD WHERE ANY SEVERE IMPACT COULD BREAK THE STEM AND CAUSE A RAPID LOSS OF TIRE PRESSURE. I CALLED THE DODGE DEALER WONDERING IF THERE HAD BEEN A RECALL ON THESE VALVE STEMS. THERE HASN'T BEEN. THIS SHOULDN'T HAPPEN AND IS IN MY OPINION A SAFETY ISSUE THAT NEEDS TO BE ADDRESSED EITHER THROUGH CANCELLATION OF THIS MANDATE ON TIRE PRESSURE SENSORS OR ENSURING THAT THESE VALVE STEMS WILL NOT DETERIORATE TO THE POINT THAT PERSONS DRIVING THESE VEHICLES ARE PUT IN DANGER. *TR”

“TL* THE CONTACT OWNS A 2010 DODGE GRAND CARAVAN. THE CONTACT STATED THAT WHILE DRIVING AT APPROXIMATELY 70 MPH, THE TIRE DEFLATED AND THE LOW TIRE WARNING LIGHT ILLUMINATED. THE FAILURE RECURRED ON THREE DIFFERENT OCCASIONS WHERE A DIFFERENT TIRE DEFLATED EACH TIME. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE VALVE STEM NEEDED TO BE REPLACED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 40,000. UPDATED 09/09/14*LJ”

“DRIVING ON LOCAL ROAD, IN CHICAGO WHEN I DISCOVER A TIRE IS FLAT. I NOTICE THAT THE VALVE IS BADLY CORRODED AND THAT THE NUT THAT SHOULD BE HOLDING IT IN PLACE IS MISSING. WHILE CHANGING THE TIRE THE VALVE STEM (TPMS UNIT) FALLS INTO TIRE. THE SUDDEN FLAT WAS CAUSED BY CORROSION OF THE TPMS UNIT WHICH CAUSED IT TO BE LOOSE AND TIRE PRESSURE TO DROP. RESEARCH HAS SHOWN THIS TO BE A COMMON PROBLEM, EXISTING FOR MANY YEARS, THAT BOTH DODGE AND ITS ASSISTANT, THE NHTSA, ARE IGNORING. *TR”
