Has anybody ever had a dead TPMS sensor on his RAV4 Hybrid (2017) due to low battery and if yes, after how many years and miles (or km) did that happen.
I'm especially interested in the lifespan of the original Toyota sensors, that were mounted in the factory.

don't know about your 2017 specifically w/o part number

but my 2013 (now 11+ years old) Tacoma sensors work fine today

it is common for them (toyota sensors) to go 14 years or more
it is uncommon for them to fail before 10 years

-------------------------------
lifetime also as has to do with mileage as they go to sleep when vehicle
is stationary, and wake up when wheels rotate. so if you put on serious
miles they may have a shorter life but still they last a long time... and a 2017
shouldn't be dying now, but take mileage into account

Thanks for sharing your experience.
My summer tires need to be replaced after about 45.000 km an 7 years and I'm uncertain, wether to use the opportunity to also renew the sensors.
But I guess I take the risk and will not replace them now.

I have taken pictures in 2017, the sensors look like this:

My 2010 Prius sensor(s) failed around the 12 year mark.

That sounds promising, thanks.
How many miles/km did you have by then?

This car is only driven once a week or so, for a few miles. The sensor(s) failed around 30K miles. I am not sure how many batteries have failed as I have not changed any but at least one has failed.

Hello engineers, can someone please invent sensors with inductive charging?!

Next generation of PHEVs will be ICE only and you plug in the tires when you get home each night.

I'd try to shrink down the mechanism from those flashlights you shake linearly to charge but at that size the power gain has got to be too small to justify the cost.

My son has a 2007 RAV4 with the original sensors (17+ years). The only time I’ve had a sensor go bad on one of my cars (various makes) is after a tire change or flat repair. I think some tire service people drop them on the ground, toss them or something while the tire is off the rim. I have no other guess for the coincidence.

You would still need a battery in the sensor to charge. Why add the charger, which could also go bad. Instead of one failure point, you now have two.

The OEM TPMS sensors on our '11 RAV4 are still working as when new.

@Blogson and @Indiana Driver: very interesting, thanks for the reply.
There seems to be a good chance, the sensors will also survive my 2nd set of tires i.e. the next 7 years.
Would save me around 200€ ($).

Well, yes. I'm an engineer myself and can't think of a way how that could be done elegantly.

Why add the charger? It would safe many sensors, that are good for a couple of more years, to be replaced precautionarily.

2017 Rav4 hybrid
Original TPMS, 165k miles now and just recently started to get TPMS alert on one of the tire only.

My Toyota TPMS sensors lasted almost 13 years. Mileage approximately 65,000
