Has anyone experienced a problem with the metal valve stems on the wheels showing stress cracks or completely snapping off.

We recently had a cold snap up here in Michigan and have seen two cases of  valve stems with the tire pressure sensor showing signs of fatigue or cracking.  The first case we had a 2006 Dodge Grand Caravan equipped with the low tire pressure monitor system snap off while we were filling the rear tire with air.  We replaced the tire sensor at the local Dodge dealer and were told six other people had ordered that part the same day.  

The Second Incident one day later was a on a 2007 Jeep Liberty equipped with a low tire pressure monitoring system.  We had our technician inspect the valve stems and noticed one was cracking.  Customer was advised since vehicle was under warranty to bring to the dealership for service.

Please respond if you have been seeing issues of this in your area.  Just curious if these are two isolated incidents or the beginning of an issue.
