TPMS Keeps Going out and in

[Silver spruce ST]

I have a 2020 Explorer ST.
Lately my tire pressure sensor keeps going out and then they come back. I had the front passenger replaced and now the other three went out and came back now the rear passenger side went out. The dealer told me that is too early for them to go bad, but the one replaced is ok. Some tell me that it's a frequency issue, What can be the problem could it be the battery in the TPMS? I'm willing to buy them and just replace them but I have an extended warranty that should cove it with my $100.00 deductible. Please advise. THANK YOU ALL...

They do intermittently connect before they die completely. That would be my guess if just one of them flakes out at a time. Even if new, maybe it's been sitting on a shelf a while. One of them just died on my 2020 ST as well and I'm thinking the other 3 are not far behind.

That is the same way I feel. They replaced one and that one is fine, now the other three are acting up.
