Tpms sensors failing

[Dieselcamino]

Hey guys, I got a flashing tire sensor light yesterday, checked the screen and it looks like my pass. rear sensor died. (Seems premature for a 2018 with 35k but whatever) driving today the drivers rear one went out as well.

 Think the sensors are that quality where the batteries would die 18 hrs apart or something else failing in the system?

I'd maybe try relearning the sensors before saying both the batteries have died. Most batteries are made to last 7ish years and it's tough to say the actual build date of the sensors installed when they buy them by the millions.

From what I gather you need a relearn tool for these years, unless there is some other trick out there

Does the dashboard show you a PSI value for those wheels ?  If not its likely the sensor batteries are dead. Shop around though, I bought 2 sets from Amazon of the Shrader brand for less than half of what the AC delco one go for and they are literally the same units.

The dash showed all but the pass. rear yesterday then today both rears went out, just seemed funny I would loose two that close
