The end of the tire stem broke off when I was refilling the tires. This prevented the tires from staying filled and I was nervous about driving the vehicle until I could get it to a shop to be repaired. We replaced all the stems, but replacing the sensors was too expensive. If this damage had occurred while driving, a sudden flat tire could have been very dangerous. Never thought to take pictures for a report until after we had already replaced the valves.

On Saturday, September 28, 2019 I was driving on U.S. 36 from danville, in to avon, in. Near the intersection of 550 E my front passenger tire flew off my car while I was going 55 M.P.H. luckily I was in the slow lane and was able to pull off the road and no one was hurt. The reason I am writing is because all 5 studs are missing from the wheel hub. There is no metal remaining and no signs of shearing. I dont know if this is a recall or if not, maybe it should be.

I bought a vehicle 3 days ago. I complained about the tires sounding like it was wobbling. I told the owner and other employees that it sounded like something was wrong. They said that they did not hear it but had the tires balanced and the rotors turned. I ran my kids to basketball practice and later on that night the tire sounds got worse and we're much louder. I was driving home and just turned into my neighborhood and my front driver side tire flew off. The tire and rim we're traveling through a yard at 30+ mph. I slammed to the ground and stopped the vehicle. It was terrifiyng. The flying tire and rim would have fatally injured someone if this was in the daytime hours.

Low tire pressure alarm initiated at interstate highway speed, roughly 70mph straight line travel. Pulled over and discovered the metal valve stem had cracked just below the plastic cap and had leaked about 6-8psi out of 36. Contact with the tip caused it to crack off completely causing rapid deflation of the drivers side rear tire. Would have caused significant damage possible accident if vehicle had still been moving or if response to tire pressure warning was delayed. High hazard failure. This is the second valve stem failure for this vehicle, but the first was a corrosion leak around the base which was much slower.

Valve stem was cracked, and tire was slowly losing inflation. Thought it was a nail and drove it for a couple of days before my appt. To get it looked at. Was told that this is a major manufacturing problem with this vehicle. Lucky I was not on the road when it totally broke and deflated the tire on the spot. Fixed the one and was told I should replace them all. Very costly repair. Now my warning will not go away and was told this too is a problem. So I will always have the warning even though it is all working okay.

The contact owns a 2010 Chrysler Town and country. The contact stated that the wheel stems prematurely failed. The vehicle was taken to an independent tire repair shop where it was diagnosed that the stems needed to be replaced. The manufacturer was notified of the failure and was to respond back to the contact with their recommendation or solution. The approximate failure mileage was 77,000.

On two separate dates this summer while traveling at speeds between 50 & 60 mph I had tire pressure sensors brake causing the tires to go flat. Fortunately I was able to bring the car to a safe stop but in both cases I had to purchase new tires because the tires which were relatively new could no longer be used. I am most concerned about the safety issue as I was told by the tire dealer that tps failure is quite common. Not only could the tire going flat cause an accident but on one of the failures I was put in a very dangerous position to change the tire.

This is the 2nd time I have had a tire pressure sensor beak inside tire causing the tire to go flat as well as having a fire on the inside due to the friction. (last time was in 2014). I did keep the tire with burn spots as well as the tire sensor from Firestone. I was lucky that I was on an off ramp when this happens one not going 70 mph on the thru way (I75). Last time my dealer (Chrysler Jeep Dodge in brandon fl) did replace a sensor as well as the tire. (October, 2014 / a week after purchasing this car). Many mechanics state they never seen this problem; however, I have experienced this twice.

- Riverview, FL, USA

I have had 2 flat tires from the tire pressure sensor, due to cracked and split collars that have deteriorated. The collar was missing and Chrysler denied any problems. I have replaced all 4 sensors and have retained 3 of them.. the collars could not be saved as they deteriorated upon removal. The remaining two were replaced today as the collars were splitting and soon would break off and possible cause an accident. The two flats occurred in my driveway, and I drove to have the last two replaced.

Hardware and nut securing the tire pressure value to the wheel cracked and fell off resulting in a rapid loss of pressure while driving on the highway.

Tire pressure sensors always read differently and display a warning in the vehicle information system even if all tire pressure are correct and exactly the same.

The vehicle was being driven at a slow speed (less than 20 mph in a 35 mph zone) through a normal water puddle (approximately 10 feet long and 4-6 inches deep) and the spare tire which is stored under the vehicle came off and was dragging under the vehicle. This was a city street with normal curb and gutter for run off. Other cars were slowing down and driving through the puddle without incident. Repair costs are estimated at $400+. this was reported to Chrysler as well.

After putting some mileage on the vehicle, I start to notice uneven wear on the tires this is with going to the dealer every 3,000 miles or every 3 months for their recommended oil changes, and tire rotations. I also notice a crack on the sidewall I spoke to the dealer they said it is not covered. I was upset it is a new vehicle with about 6000 miles, they refuse to seek any free fix. At this time as I drive the vehicle I can feel the roads every imperfection due to the early premature wear of the tires.

I have a 2010 Chrysler Town & Country which is in the service department at taylor Chrysler dealer. My van was making a very loud roaring noise. I was told to bring the van to the dealer because the wheel bearings are under extended warranty due to a defect. When the mechanic called he proceeded to tell me T that the front bearings are bad which would be covered. He also stated that the right rear bearing was bad as well but would not be covered. He also stated that there is no way that wheel bearings at this mileage should go bad this is not a normal wear and tear part of a vehicle. I would hope that you can do an investigation to show how bad the rear bearing are as well. This is obviously a defect as well but, I am going to be out $500 to make the repair. I have done some research and I am not the only one that is/has dealt with this problem.

All of the metal valve stems are corroded and cracked, and one of our tires is slowly leaking air as a result. We've been told this is a major safety concern because the valve stem can continue to crack and eventually break, causing rapid tire pressure deflation. The result can be loss of control of the vehicle when the tire blows out and possible catastrophic results. I have noticed several other Chrysler and Dodge minivans in my area with the same problem. I live in syracuse, NY and to combat 115 inches of snow each year, they use road salt. The metal valve stems used by Chrysler do not resist corrosion. I replaced one at the dealer and cost about $250 between the part and reprogramming the tps. This is a potential deadly issue and Chrysler should be forced to recall the faulty valve stems that corrode and crack.

While beginning to drive the car display light of the dash board will show a slippery sign and the steering will lock up and engine turns off. You can not steer the car - you have to brake, place in park and start the engine back up. This happens twice or so a week. Happens also when going over a bump and in dry conditions(meaning it's not wet when light is displayed slippery). - already had the recall L25 done in August 2011. This is a huge problem for crashing the car (since you can not steer)! already caused an accident for me in wet pavement(02/2014).

Corroded nut on left front wheel valve stem allowed the stem to drop into the tire resulting in sudden loss of air pressure in tire. There was no warning prior to very sudden flat tire.

- Penobscot, ME, USA

2 flat tires caused by failed tire pressure sensors. The valve with the tire pressure sensor broke off on 2 tires during the first incident (2 flats at once). 2nd incident happened on March 9, 2014 in a car wash (vehicle has roughly 56K on it at the time of the 2nd incident).

- Orion, MI, USA

While traveling about 40 mph, my right front tire completely went flat in about 3 seconds. This caused my vehicle to pull to the right. I went onto the shoulder of the road. I just missed the guide rail. Upon inspection of the tire, I found the stem had cracked just below the plastic cap. I was on a very busy road. If it had been my left front tire, I feel that I would have crashed into oncoming traffic. These tire safety valve stems are unsafe and should be recalled and replaced.

My vehicle was parked in the garage. I was inside and I heard a sound that sounded like a gunshot. I immediately went into the garage and noticed that the drivers side rear tire was flat. I looked at the wheel rim and found the valve stem on the wheel sensor had blown off. Looking further I found the stem with the valve cover attached was on the garage floor. I believe the break most likely could have been caused by metal fatigue. The stem seems to be made out of aluminum. I had to replace the TPMS sensor at a cost of $169.65. My call to Chrysler to report this incident was met with the answer that my vehicle was out of warranty. I am concerned that this problem might be happening to other drivers and they might not know what caused the air to escape. What if I was on the highway and this happened" the tire went flat in seconds. Would I have been able to control my vehicle and get to the side of the road, or would I have been a statistic? could this be another Ford Explorer fiasco? do you think these valve stems should be replaced with a metal other than aluminum" my advice to the reader of this letter, and anyone else who might read this incident information, please check your valve stems. If they have tms sensors, check to see if they are made out of aluminum. Your thoughts. Looking forward to hearing from you soon.
