I will let you know next Friday if I was able to get flashed to build 2170. My Rz is build 2050.

That's really strange. I would hope you could get the update, giving you the battery % display, regardless of trim. My dealer has never mentioned a word about an update that provides more range, though I got the % update to the display. Maybe a gimmick? IDK. I would call another Lexus dealer, if you have another near you.

My Lexus dealership e-mailed me this
"OTA updates for our Lexus Interface models are rolled out in “waves” rather than distributed everywhere simultaneously. I’ve attached 2 pics showing the software version (2170) that does show the SOC% within the on-screen dashboard image (see images). If your software version is lower than 2170, that would explain the “missing” SOC% graphic. If you want to bring your vehicle in so we can determine if a flash-forced update is available for your vehicle, you can set up an appointment with our Service Department.

"

I am going to call them tomorrow to schedule my appointment.

So why do some RZ already have the update but others don't? Doesn't really make sense does it?
I'll try to get some more information through my Toyota Motor contact

It was shipped from the factory with the update. There could be hardware or software revisions between manufacturing dates.

From what I read from the Solterra forum, the update does two things: 1) adding the SOC %, 2) moves reserve wKh from the below 0% SOC to the usable 0-100% . Posters from there suggest that instead of having a 80 km of sub 0% range is now 26 km now; this assumes you have 54 km more range in the 0-100% SOC.

Personally, for my needs it does not make any difference between those two points.

Well, I just got the update on my premium.

There is only a 3 mile difference with or without economy AC on instead of the usual 30 mile difference. I will see how it behaves over the next couple of weeks if usable range is and how accurate. When I drove home from the dealership that was 8 miles away it went from 48% to 47%. I wish I can see remaining kWh.

 

[imurrx]

nope. not holding my breath.

I was able to schedule my service today. There was no update.
My car is still on build 2050.

I got an email from the tech advisor at my local Lexus dealership sharing information from a tech forum for Lexus service and dealership. On the email it states that there is a TISB that the update is only for the BZ4X. Some Rz say it is available but the TISB advises not to update yet. The techs speculated that it may come down in the future.
