Tire Pressure Monitoring System problems of the 2007 Dodge Nitro

Failure of tire pressure monitors on Dodge Nitro. The valve stems on my Nitro are fatigued and are breaking apart. I have had two replaced and fear one of the original stems remaining will possibly blow while traveling at a high speed causing a crash.

Tire sensor stem cracks causing tire to lose air. I will have had 4 replaced in last 12 months. These are not due to damage. They are stress cracks. 2007 Dodge Nitro. . Read more...

In cold weather, 4 to 5 degrees and colder, the tires loose pressure. It appears to be the valves which contain the sensor that indicates if a tire is low in pressure. Above 5 degrees the tires maintain the required pressure. I have taken to carrying a hand pump so that I can pump the tire as needed.

The contact stated that the vehicle has had a flat tire every three weeks since it was purchased. She also stated that the tire pressure monitor lights remain illuminated. The dealer continues to inspect the vehicle every three weeks and stated that the tire is not leaking. The dealer always replaces the valve stem, however, the tire pressure lights remain lit and the tire continues to flatten. The dealer stated that they will not replace the tire because they cannot prove that it is defective. The powertrain was unknown. The tire failure mileage was 5,123 and the vehicle current and failure mileages were 5,800.

Tire pressure meter gives a false alarm intermittently during interstate highway driving. Alarm chimes and says, "check tpm system" and indicates the right rear tire has no tire pressure. After awhile the system returns to normal and then alarms again. This can happen anywhere from within a half hour to over two hours between alarms. The problem has been attempted to be fixed 5 times. All tpm parts, sensors etc have been replaced. Dealer now says it could be cell phone causing problem.
