Driving with my wife on I-95 North in Connecticut early Saturday morning, our right rear tire instantly lost air pressure. I saw the low air warning light go on first, then immediately felt the vehicle wobble to the point where I could barely control it. I was able to safely get it to the right side shoulder where I changed the tire. I noticed that the entire valve was missing from the rim. I did not notice any nails or other penetrations of the tire itself. Had it been one of the front tires, I might have lost control of the car. When we got to a tire store to have the bad tire checked out, the mechanic & the owner said we had defective air pressure sensor valves and that we essentially experienced a blowout. The mechanic showed us the other valves and they were all cracked as well. We had them all replaced and had to buy a new tire as well. The cracks in the sensor valves were obvious. This is a major safety matter that could cause fatalities if they have not occured already.

On 4 separate occasions while driving my vehicle the ABS system on the Jeep turns on and my car comes to a stop. I am unable to move the car and I have had it towed to the Jeep dealership to be looked at. My car has been in their shop 4 times for service. Each time I am told the problem has been fixed and each time it occurs again. This issue is an extremely dangerous situation as my car literally is unable to move and comes to a complete halt. It has occurred while driving on the highway, at an intersection, and driving up hill. The dealership is unsympathetic and I am unaware as how to proceed. Thank you.

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.

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 updated 09/16/2014

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.

I got this vehicle on Sep 2013 when took it front the dealer I noticed front end vibration, call for appointment when arrive to dealership they said it needed new tires bought new tires at local pepboys, when back with same problem, they then said again are the tires when they were new.this vibration is coming from front end is very loud sounds like wheel bearing they said that is the way the car is. Alignment was performed, still has vibration now I notice right front tire is wearing on out side could be the camber, non of this repair were done at dealership even under warranty I had to paid out my pocket I don't think is right I am doing the research for those lazy mechanics alignment was perform at pepboys they said the camber on rh tire can't be perform correctly because lower control arm doesn't move out no more. Now when turning the vehicle to the left the wheels seems to be touching, scratching something very hard took it to dealership again after showing that I performed and alignment and they don't know what is causing this I think is unsafe because when I am turning vehicle seems to slow down or something is holding it back I notice that front left brake hose is rubbing the rear of suspension fork at bottom of control arm when turning left there is signs of wear on brake hose same is happening on right could be excessive turning radius on this Jeep that is why may be causing this rubbing noise putting stress on cv axle or bearing.

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!!!!
