The failure recurred one other time, with the rear driver's side tire. The contact spoke to world Jeep Chrysler Dodge Ram 681 shrewsbury ave, shrewsbury, NJ 07702 who stated that the contact should speak to Goodyear, the tire manufacturer.

I have michilen tires which are laoded with dry rot cracks. There is plenty of thread still left on tires but need to be replaced due to rot on thetires I have had several issues with flat tires. The valve stem are literally breaking off when adding air to my tires. So Jeep knew of this problem with bad valve stem in 2008 yet they kept using them in 2009"????????? how many people have to have blow outs/accidents before someone is held accountable??????????"

I was driving on the garden state parkway North traveling approximately 65mph (the speed limit) and I was in the left lane of the three lane local lanes. I drifted too far to the left and hit the rumble strips on the side of the road. Immediately, my TPMS light came on and I pulled over right away. Apparently, my TPMS sensor on the tire broke and was letting air out of my tire. What happened was, the metal screw that is around the metal valve stem sheered off and nothing was holding the valve stem/TPMS in place except for the air pressure inside the tire. When I ran over the rumble strip, it must have dislodged the sensor and started letting air out of my tire. I went to a tire shop and they found a broken TPMS sensor and they replaced the valve stem with a standard non-TPMS valve stem. My tire was undamaged and is back on the rim, so it was 100% a problem with the TPMS sensor. Furthermore, last year, I had a similar problem. I got a flat tire and my TPMS was damaged. Now, looking back, I feel that the TPMS must have failed causing my flat tire. In that incident, my tire was destroyed because of the flat. I notice now that Chrysler has a newer version of their TPMS sensors that go on the wheel. The new version has a rubber valve stem, while the ones on my vehicle have a metal valve stem. Obviously, Chrysler has found an issue with the metal ones and have updates their parts. I think that this is a serious issue and even though I am ok, I can forsee this causing major problems. Chrysler should have my remaining TPMS sensors replace at no cost to me.

Tire had gone flat twice for with no damage to the tire it self. With further inspection there was a crack found on the rear face of the wheel starting from the inside and working out to the tire sealing surface. There is no damage to the tire and no bend or scraps in the aluminum wheel indicating an impact. There is corrosion in the crack which would lead one to believe this to be a fatigue crack and it being in the wheel for some length of time. Vehicle was inspected by dealer, photos where taken and the dealer left the decision to replace the aluminum wheel up to the regional service manager. The regional service manager denied the claim on the basis of wheels being a wear item. This was relayed via the dealership service manager. I have photos of the wheel, and the wheel itself is available for inspection. It is clear that this is not an impact crack, but instead a fatigue crack. At this point in time we are not driving the vehicle for fear the other wheels might be doing the same thing.

As I was driving my 2009 Jeep Grand Cherokee on a highway at approx 70 mph my left rear tire instantly went flat immediately following a low tire pressure indicator. When I stopped my car to check the flat I noticed that the tire valve (tire pressure monitor wheel sensor) was gone. When I changed the tire I realized the pressure sensor fell into the wheel because the threaded nut that holds the sensor in place failed and broke in two causing the tire to loose all its air at once. I checked the retaining nuts on the remaining wheels to discover they were all cracked badly and could fail at any time. I later learned from the dealer that Chrysler has updated the part number to a new rubber valve sensor, and the sensor I have is no longer available. Chrysler knows about the problem but to my surprise has not issued a technical service bulletin or a recall. What if it had been a front tire that went flat causing an accident resulting in injury or death to myself or someone else? I've called Chrysler cust assistance and am working it out with them currently. But from what I've gathered so far they don't see this as a safety issue. To me this is a huge liability issue, and an even bigger safety concern.
