Default 450h traction battery cooling fan question

We're on our 3rd hybrid. Our new RX450h traction battery cooling fan under the back seat seems to run consistently after the car is driven for a few minutes.

Our previous Prius and CT200h did not exhibit this.

Is this typical of the 450h?

Are you sure you are hearing the battery fans and not the seat ventilating fans?
The seats have two (2) fans each and they sound quite loud near the rear seat
floor. Try turning them off as well as the HVAC and then listen for your fan noise.

mcomer,

BINGO! It was the driver seat ventilating fan noise I was hearing, not the traction battery fan.

THANK YOU!!!!

Glad it was so easy. To enhance the effect of the seat coolers, turn the vent on the back of
the center console off by rolling the valve wheel down. Remember to turn it back on when
using the back seats!
