All of mine started going.  First it was just a blank for one pressure reading.  Had just the one replaced.  A week later, get TPMS system fault code B1182 and all pressure readings blank.  Manually trying to relearn failed with another wheel TPMS sensor not responding.  Replaced that one.  System error a day later.  Ended up replacing the final 2 and all are good now.  5 1/2 years, 100k miles.  It was just time.
