The early builds did not come with the preferred accessory package. I guess that's the downside of getting something that just got released. My dealership did not even know that the car was coming with the Preferred Accesory Package until the car got there, but by then the car was already sold to me with the price worked out without the package. I basically got the package for free 😎.

Same here
We've been driving around the new RX over the weekend since purchasing last Wesnesday and we noticed a fizzing/hissing sound coming from the engine bay while the climate control is on. Particularly when it is set to auto whether AC is on or not. I thought it was the AC compressor but I'm not sure if it is because it is constant and quite noticeable while idling at a traffic light and it also elicited a comment from my wife. If I turn off the climate control/fan off entirely the sound goes away shortly after. Does anyone else experience this? I have an FSport 350 and was wondering if this was by design or if it's an issue. Any feedback would be appreciated.

I found out what this noise is coming from. It's the ac freon circulation. When you turn off the ac, you can hear it slowly dissipate. When turn the ac back on, it comes back.

Here's something funny, my Active Cruise control shut off when i was in heavy traffic and a motorcycle blew past me lane splitting.... LOL I think i got some sort of error message saying something like "car in front is no longer there" or something like that....

I'm not sure if it is normal or not. I'm wondering if anyone else is having this sound or not. It's not overly annoying but there shouldn't be any noise like this inside the cabin. You can only hear it when the music is low and at a stop light.

I heard it today too when I was stopped. It definitely is annoying and I will probably bring it up at the first service. It also have a door trim (leather part) corner that isn't clicking/connecting correctly.

Discovered another brilliant feature which blows my mind:
"Front door opening linked windshield wiper stop function"
(vehicles with rain-sensing windshield wipers)
When “AUTO” is selected and the windshield wipers are operating, if a front door is opened, the operation of the windshield wipers will be stopped to prevent anyone near the vehicle from being sprayed by water from the wipers, provided the vehicle is stopped with the parking brake applied or the shift lever in P. When the front door is closed, wiper operation will resume.

BTW, I'm not sure if that was mentioned on this forum before, but 4RX's back door windows can now be lowered down completely to the very bottom of the window frame. A huge thing for whoever is trapped on backseats, I guess 
I know my kids will love that.

16 RX Registering SmartAccess key to Seat Memory
After watching many youtube videos on how to Register Smart Access key to the pre-set Seat memory on Lexus, I found out that 16 RX method is different.
So here it is, hopefully it can help fellow members:
Get into your RX with the smartaccess key that you want to register and close the doors. Then you need to Press the Seat Memory button ("1","2" or "3") and the door lock switch (lock or unlock) till you hear the buzzer. My mistake was that I pressed the Seat Memory Button and the SmartAccess button as shown at almost all that youtube videos for other lexus models.
[Edit 12/9] apparently this is the same procedure as the 3RX as rayaans pointed out.

This worked, but I think it kinda odd. On my other car BMW the BT input is constant no matter what volume you have selected on phone. I wonder if there is a way to change this.

CHANGE # OF BLINKS FOR TURN SIGNALTried
tried to change the number of blinks from 3 to 5 as posted by "DECHAR"
but not having much luck after many tries. Went to the original GS post
and followed directions but still no luck. Maybe these instructions do not
apply to the 4 RX. Has anyone else had any luck.
