Low air pressure in tire(s) light came on in my 2005 walter P Chrysler Town and country when my wife and I left our house. Turned around and came home to check air in tires. Front right tire was low and when I took the cap off, the valve stem broke off in my hand. The tire completely lost all air in a matter of several seconds. If this would have happened to my wife and grandkids later that evening and with the temperature dropping to near zero, it could have been a very scary situation. Then I find out that this is a common problem that is well documented, yet no recalls that I can find as of yet. Unbelievable! this is very, very dangerous and I will not put these valves with sensors back on my vehicle. If anyone knows of a recall, please let me know.

TPMS. Tire pressure sensors are required on all new vehicles now to "help aid in safety?" problem is like on my 2005 Chrysler Town & Country, the sensors are made with a watch battery as the sensor power source. This is fine if the consumer can replace these watch batteries or have the watch batteries replaced when they are dead, but, "but" Chrysler has made the sensors in such a way that the sensor is completely destroyed by trying to change the batteries. One must replace the entire sensor when the watch batteries are dead. The cost for replacing (4) sensors every (3) to(4) years is extremely overpriced. So to conclude my complaint, the intent of safety is not what is going on here with the car manufacturers, but a new opportunity for profit. See, what this has now caused is that since the cost is so high to replace the sensors when the consumer should be able to change a small battery for pocket change, the consumer will just let the warning light shine and not replace the expensive sensors when a watch battery is dead. That's what I am doing. I can't be alone. Safety" only for the 1st 3 years or so....after that" same as it use to be with no sensors.

The sensors for my TPMS corrode and brake letting the air out of the tires. I went to remove 2 of the valve stem caps this past weekend and the stems broke right off letting the pressure out of the tires. In looking on line, this appears to be a very common problem with numerous owners. Some simply start leaking just from age and corrosion. This appears to be a very serious safety hazard.

Tire pressure sensor monitor began flashing a message in March, 2008 that tire pressure was low. Mechanic checked and tires were fine. Had a flat tire (puncture) later that month and when I took car in, mechanic suggested replacing all four tires as they were the original tires on the vehicle and had 65,000 miles on them. When they went to replace the tires, had an additional expense of $300 because the tire pressure sensors had seized and could not be removed! three had to be replaced! only one was removable. Upon a call to the dealer was told that this sometimes happens because people put air in their tires at unknown locations and they can introduce moisture in the system. I do not put air in my tires - the mechanic does this for me - with very specialized equipment that does not produce moisture. The tire pressure system has been defective from day one - I have had to take to the dealer twice to have it reset because when the temperature drops in the winter (below 10 degrees) the monitors go off telling me I have low tire pressure.

Tire pressure sensors are not correctly calibrated on by '05 Chrysler Town and country mini-van. My dealer refuses to calibrate them. They insist that I over inflate my tires to compensate for the mis-calibrated sensors.
