I realize this as an old post but wondering if the OP ever solved the TPMS issue?

I moved my rear balance ALMOST to 100% rear. Just a tick away from 100% made all the difference. This is not how a balance control should work but in my case it made a huge beneficial difference.

My 2024 ES350 behaves the same way. I have to adjust the balance so its almost 100% towards the rear for the speakers behind the door to wake up and to hear much from the rear speaker.

I adjusted the Balance setting so that it was heavily biased towards the rear speakers, a slight tick away from 100% rear. What a difference! The speakers behind the front doors sprang to life and the whole system sounded way better. I'm no audiophile (even after working for Bose!) but it sounds great. I cannot believe how non-linear the adjustment balance is for the rear.

Its the first thing I noticed when I sat in the 2024 we were about to buy and listened to the radio. I didn't think much of it at the time, figured it was just a balance setting. I played with the balance after taking delivery but it really did not help.

Same problem on my 2024 ES350.
