Problems with 2010 Jeep Liberty TIRES

For the second time the valve stem is defective and corroded. *tr

Tl* the contact owns a 2010 jeep liberty. the contact stated that the tire pressure sensor light illuminated. the contact mentioned that while unscrewing the cap for the front passenger side valve stem, the top fractured causing the tire to deflate. the contact experienced the same failure while unscrewing the cap from the rear passenger side tire. the vehicle was not diagnosed or repaired. the manufacturer was not notified of the failure. the failure mileage was 45,000. updated 09/02/14*lj updated 09/16/2014 *js

Tl* the contact owns a 2010 jeep liberty. while driving approximately 70 mph, the contact noticed that the sensor near the vault stem was corroded. the vehicle was not diagnosed or repaired. the manufacturer was notified. the vin was unavailable. the approximate failure mileage was 62,000.

While driving the tire pressure warning sensor activated and the tire went flat. the stem valve was completely corroded and feel inside the tire. the dealership said they are no longer using the same type and we paid for a updated one. *tr

I was driving 50 mph on a paved highway. the air pressure light came on. a few seconds later there was a rumble noise. i pulled over and looked at the tires. one was completely flat. i had thought i ran over something very large causing an instant flat. after removing the tire, we noted that the tire was still good. the nut holding the valve stem/pressure sensor in had broken. the valve stem/pressure sensor component was found inside the tire. the result was a very large gap where the valve stem was, allowing the tire to instantly deflate. when checking the other valve stems, one of the other nuts holding the valve stems in was also broken. the jeep is parked until we can remove all of the valve stems and replace them. we will not drive it as it is. we will be replacing the valve stem/pressure sensor component with the old fashion style valve stems. i would not continue to drive the vehicle with the stock equipment. i would always worry about what would happen if the valve stem broke on a front tire going expressway speed in heavy traffic. *tr

Low psi indicator on spare was on so i lowered the spare tire to put air in it and i noticed the valve stem was broke off at the top. after looking on the internet i found this is a common problem with chrysler on their valve stems. it happens all the time on all wheels not just the spare. the cost to fix is around $100 a tire!!! in till chrysler fixes their cheap valve stem sensor system i will put in the old fashion rubber valve stems and just put up with the dash lights!!!! *tr
