It sounds odd to me. I drive a 2016 RX 450h and auto low beam works dimming only in "slices" where vehicles are present keeping high beam all around (and you see the indicator on anyway while  oncoming cars are not disturbed). The switching speed  is not a problem AFAIK, provided oncoming vehicles have lights on 🙂

Another difference is given by short  traits, first minutes of use are most fuel consuming ones, mpg are better in long distance trips.

Sport mode is not the best for fuel sparing, try using normal or ECO. Another suggestion with high temperatures is to use  AC to keep HV Battery pack in good temperature range, and a recommendation to verify good air ventilation trough it. You should hear hv Battery fan only with cabin  at high temperature; usually I set my AC to 24 Celsius degrees.

Slightly better, around 43 with mine. You can give a look to spritmonitor  and see the range users obtained.

You can remove them extracting from cradle on rear of seats while pressing the button under it; I took off them and put apart for when I will give  my RX to a new owner (hopefully not soon).

Having a phone cell with NFC, I suggest a gravity holder so to have no need of a magnetic plate on rear that could potentially give problem in NFC .

It is exactly like my GS300h, I still miss it. Traded in for my RX because of V6 nostalgy. Great car.

High speed?

In my experience with RX, Sport mode forces thermal engine to stay ON even at low speed, probably to be ready to give power if needed in fast acceleration; at higher constant speed, when engine is already on,  mpg are not different from normal mode.

In ECO mode, mpg are a bit better because this mode use other strategies to limit energy waste, like AC management and a "sleepy" performance. 

My usual mode is Normal, as when I set Sport mode I like to have some fun not considering fuel spare.

In ECO mode and normal conditions,  ICE keeps off till the mid of eco range on power meter, but in this cold weather it goes on easily to have a warm temp in cooling system and AC, so  nothing to be worried;  cold weather affects  mpg negatively too.

About mist in rear lights, better give a look, no mist in my RX.

Passing from a CT to a v6 RX is a big jump, enjoy your new car but do not expect  same fuel spare  😄

After some time you could find yourself more at ease using normal mode, anyway power is more than sufficient in any mode, compliment again, from photos it looks like new.

I love my RX450h, but I had the chance to try a NX 450h (plugin) while waiting for a fast service  intervention, and I had positive and negative feelings comparing the two cars.

NX , expecially in EV mode, was faster and really quiet,  the stiffer chassis improved driveability, and infotainment (compared to my 2016 RX) is now up to date; even fuel consumption is far better in hybrid mode, but if you plan to use gasoline and not to charge electric, NX Hybrid has more sense (even with a little worse 0-60 time). The suggestion is for a NON Fsport choice.

And now, the bad: even if in most of time (more than in RX) engine is off (and then silent), when it goes on the sound is of 4 cyl, very silenced but different from V6 in RX. The question is: what I would do if I had the need to change my RX? Probably I would buy a NX450h, not needing more space and considering new RX has a four banger too, but at the moment I don't need  , so I may wait new models, and sparing money (not irrelevant topic).

Who did change tyres? A professional operator who knows how not to damage sensors during operation?

  When I tried to accelerate to join the motorway (in auto D) i just got lots of engine revs but virtually non-existent accleration. 

The eCVT system does not have real gears. You have to consider taht thermal engine revs are linked to Power you ask, and are not linked with speed, if you require fast acceleration don't  care of engine revs and press the pedal , no fear to damage engine.

If it seems to you  that car is "slow" verify in which MODE it's set, and if it is in ECO switch to Normal or, wanting more in SPort mode.  I tried a NX 450+ and it's brilliant, with a 0-60 time of 6 seconds (or a little bit more).

Remember to set high beam light ON with Auto mode.

Another precaution while charging 12V Battery with any charger is to leave all systems OFF if you are charging without disconnecting Battery + or - connector.

The solution is not using AHB at low speed, switching  off it and operating manually 🙂

Full beam activates over a fixed speed, under this speed AHB keep beam off, accordingly to rules.

After registration of my car in Lexus tech site I downloaded the full list of optionals with VIN code.

How they did? It seems they made a copy of key code. A team of  3 burglars, as I can see...

Probably a signal "sniffer" has been put  near front left wheel and removed before stealing ?

The problem with hybrid with ecvt is that, if you have no more fuel , it's quite a catastrophe, as you discharge traction Battery and and that point after refuelling, you can' restart car anymore. To avoid this, the left range indication is very pessimistic to force users not to end fuel. Using a plug-in may complicate more the estimate range. My simple rule is to consider to to absolutely  fuelling  below "zero" range, even if there could be made many miles before total disaster. Besides, a fuel pump working with no gasoline circulating risks to break with another expensive repairing.

S mode, as I can see, it's only a way to use "gears" like in manual gears cars,  but in our hybrids it is useful only to avoid in long downhill traits to have more engine braking ( like in smaller hybrids with "B" mode) downshifting; the real difference in performance is using Sport mode, accepting the fact you will burn more fuel. In Rx going to Sport mode (activated by centre knob) therma engine will be on for more time and at a lower speed, while electric engines will receive a higher V from Battery pack, being capable to deliver more power (and descharging Battery faster, so the need to have more charging from thermal engine).  S+ mode , if available, works on adaptive suspension  system .

If you have original 12 V Battery, it could be the cause, a almost exausted Battery. Try to read the V  and give it a charge but a ten years Battery has a reason to retire 🙂

Brake  pedal spring noise?

In this season, without needing air conditioner, my average is about 39 mpg.
