Tire valve stem was broken out and flattened out when I took out plastic cap for air filling because I got low tire pressure alert two month ago. I changed tire pressure sensor at my own cost over $200. But yesterday I got low tire pressure alert again, and found another valve stem was broken out again. Need to be recalled. This can cause severe situation not to control vehicle if it happens during driving.

I was unscrewing the plastic tire valve cap and the tire valve stem broke off in my hand. Air leaked out of the tire until the tire was flat. After changing the tire to the spare took the tire to the dealer and was told it needed a $100+ TPMS sensor replacement. This is the 2nd time this has happened on this vehicle. The first was handled under warranty. These valve stems break off easily, and make the car undrivable.

Tire valve stem broke off while at highway speed on an expressway causing the tire to immediately deflate! I was able to pull off on the shoulder and replaced the tire with a spare. Fortunately, the flat was on the right rear tire. If it was on the front I could have lost control and could have had a fatal accident. The tire had to be placed as well as the TPMS sensor. The mechanic informed me that this particular valve stem is made of aluminum and can fatigue do to road salt and corrosion. Surly this is a safety issue and the vehicle should be recalled. Due to the fear that this might happen again, I had the remaining sensors replaced at a significant cost to me. Please address this issue before people are killed.

2009 Chrysler Town & Country. Manager from the alliance for consumer protection sent correspondence on behalf of consumer in regards to blown tire and valve stem while driving 65 mph, the consumer experienced a tire blow out. The vehicle was taken to a tire shop, where the he was informed the valve stem had broke off and a rubber stem had to be installed. The sensor had to be replaced and an alignment was performed. In October 2011, while installing brakes on the vehicle, the consumer noticed another valve stem had broken off at the tip, which he also replaced. In Feb 2012, the consumer was informed that there was a hole in the valve stem again. Upon inspection of the valve stems, it was apparent, the valve stems were deteriorating from corrosion from bad metal and road elements used to treat roads in bad weather, such as salt. The consumer was convinced the valve stems were made from aluminum and the road elements were causing the valves to fail, especially in the northern part of the country.

Sometime in the beginning of October 2011 while checking/ adjusting the air pressure in my tires the rh front valve stem snapped off just below where the valve core threads in causing a complete loss of pressure. This seemed like a fluke problem, so the stem was replaced at my own cost. Today, 12/1/2011, while checking/ adjusting the air pressure again the rh rear valve stem snapped off just like the previous one did approx. 2 months ago. Some fluke occurrence? not twice. Once again the part was replaced at my own cost/ time so we weren't down a vehicle. In my opinion it appears that the metal valve stems for the TPMS are made of a faulty grade metal, and or the valve cores were over torqued, causing a fracture/ stress crack in the stem. After doing some research on the internet this seems to be quite a problem with at least several hundred Dodge/ Chrysler owners. In a way this makes me feel better being it's not just me that this is happening to, but it's definitely not an isolated incident. Now I still have two tires that have not had this problem yet, but when time allows I will be replacing all the valve stems with rubber ones and just dealing with the TPMS idiot light being on in the dash. So much for new/ easier to use technology! this wont cause an issue with me, living in Michigan because we don't have vehicle inspections, but there are several states that will fail an inspection if the TPMS light is on. In closing, luckily these valve stems failed while servicing the vehicle, and not driving down the road at 55+ mph, otherwise the results might not have been the same. I've worked in quality control for the automotive manufacturing industry for 20+ years producing and inspecting tight tolerance/ safety related parts, and feel that this really needs to be looked into further. It is a definite safety concern.
