Tire pressure monitoring system

What is your question?

Do these sensors go out often? I was told the needed to be replaced. The front two read In the 20psi range and the back are offline, according to the info on the dashboard display. Any info on this would be great thank you.

What makes this problem better or worse?

Nothing
