Wivenhoe- Mine was initially booked in for the update in Feb too, but pulled on the day of appointment, spoke to dealer and Customer Service this week but still no idea when I will get it -really frustrating.

I presume your Takumi has a HUD and the update has worked ok for you?

Economy mode alters the response parameters for maintaining the set temperature - more buffered. Range mode actually switches off the heating system as well as affecting the 4 wheel drive performance.

I have heard about Lexus Reserve, sounds like a good offering.

Wivenhoe - I took delivery of mine at the end of June last year so have been unhappily been living with this AC/Range/Display issue since then, I was booked in to have the software update to hopefully resolve the AC/Range and Battery level display function but alas on the morning I was due to go in I received a phone call to say the update had been pulled - so still waiting despite calls to dealer and Customer Service. I do have a HUD display but don't understand what the issue is because all new RZ450e`s sold now are already with the latest version - so why not mine? Regarding heating performance I found that mine responded quicker if I had the drive mode on normal and not economy.

Hi Tom

I share your pain on this issue, I understand that if we use AC Cooling the range of course will be compromised as the compressor uses a fair amount of energy, mine drops off about 40 miles off a full charge range. Like you I would like to be able to vent the car with normal outside air at the ambient temperature, however the system I believe is inadequate as it is unable to do so, and you will have noticed as soon as you turn on the fans the range plummets. So this also tells me that the published range figures are incorrect because the car would have to be in its normal state for testing, so who on earth can drive a car without any fresh air to ventilate the car??

I have raise the issue with Lexus but received a fob off response.

A premium brand car should be able function correctly, most other cars when you turn the AC off you can still have fresh air entering without the system turning the AC back on!!!

Please sort it out Lexus I have been complaining about this frustrating situation for months and this adds to range anxiety. 😠

I have been asking about the software update also, not happened yet.

Hi, I also have an RZ 450e and use the schedule in the Lexus App to programme the charging for only when I have cheap rate electricity, which is also between midnight and 5am.

Procedure: Open The Lexus + App

1, Click charging schedule, then click add schedule, then set start time, then toggle slider to set stop time then set the stop time, then select all the days in the week view that you wish to charge, then click save schedule. Now whenever I plug in to home charge it will not charge except within the time frame set in the schedule . I hope this helps, you can have more than one schedule and just select the one you want. you can also delete schedules in the app. I hope this helps . - Phil 🙂
