Anyone else having trouble with the TST tire sensor's?

[Letsgoagain]

Good evening,
Two months ago I bought the TST tire pressure monitoring system. I purchased six sensor's for the motorhome and have had two of them fail on me. The two failures happened separately on two different trips on different tires.
By failure I mean that they both gave erroneous indication of low tire pressure. At first only a few pounds under my low setpoint which sets off the alarm but they both progressively showed lower pressure.
Of course while I was driving this immediately caused me to pull over to check the warning out. After removing the sensor and verifying by sight, feel and tire guage that there was nothing wrong with the tire I removed the bad sensor.
I returned the first one after the trip to California and TST sent me a new one and it is working okay. I have called and informed them I have another bad one and will be sending it back.
Kind of curious if anyone else is having trouble with bad sensor's?
I still beleive that this is a good thing to have on your motorhome but the reliability has me concerned. After all I bought this system so I could have a reliable source to monitor the tires while underway.

Yes. I have trouble with my tst. Had six on the mh and 4 on the toad. had two on the mh and toad, kept letting air out. traded location of transmitter to another tire did the same. I think if i change the rubber tire valve to steel this might help. Don't know unitil i try it.

Yes, I had the same problem with several sensors right after purchase in March this year. They replaced the problem sensors, and recommended I use one wrap of teflon tape around the stem before I put the sensor on. All has been well until this past week when I had another sensor do the same. A replacement is on it's way to me right now.

According to other posts over the last couple of years sensor's have been a fairly common problem with all tire monitoring systems. After a few years the manufacturer's have seemed to get these issues ironed out because there doesn't seem to be as many posts about them anymore.

I think TST is one of the latest on the market, so hopefully they too, will get them ironed out.

Just installed my new tst system and all was good on the first day, but the very next day I went out to the mh and the right front sensor had failed. Just blank on the display when it got to that right front or it would pass it up completely. tst said it was a sensor so I mailed mine out today and hope the replacement makes it here before our maden voyage.

We have had ours for a year and 1/2 or so, and about 15k miles. The first set of sensors was from Saftee and they were short threaded and soft metal and stripped easily if you tried to tighten a leaker. TST replaced the whole set when they became the new distributor, that was almost a year ago and they have all worked fine. I did go to metal stems on the toad as Centrifigual force nearly pulled out a rubber one, and I was not going to give it a second chance. Once in a while it will drop the left rear toad tire, so I am planning to buy the repeater, otherwise the system has worked very well.
Have a great day Happy Trails Bert
