2024 NX 350h PREMIUM

1. AC does not blow cold when the car is not moving/idling

2. Apple CarPlay randomly stops responding. And/or Waze app goes to white screen. And/or sometimes Apple CarPlay doesn’t recognize already connected IPhone (stays on Lexus “Explore” screen).

3. Two distracting dark spots visible in the driver side headlamp light beam.

4. Is there any way to change the temperature display from Celsius to Fahrenheit?

5. Every so often when exiting the vehicle I get eight beeps, indicating something is on the rear seat. Nothing is on the rear seat.

6. Is the backup camera supposed to beep when the vehicle backs-up close to an object? My NX does not beep at all when closing-in on an object (front or back), but the backup camera works fine. I’ve checked the settings. Nothing appears to be turned off.

Any similar experiences? Any insights on how to deal with the dealership when they tell me all of the above is normal?

 

For 3, the dark spots are a quirk of whoever supplies Toyota's bi-LED(there is one projector for hi and low-beams) headlights. It was a frequent complaint among owners of the 2021 Venza Hybrid I had. The only way to escape this quirk is to get the triple-beam headlights. Literally every Toyota/Lexus I've seen with the Bi-LEDs have the same light pattern.

They don't bother me now that I'm used to them, but they are jarring if coming out of other cars.

 

Almost all cell phone connectivity issues are cell phone related as apps are updated way way more often then the car's cell phone communication software.
Switch AC in Settings to MAX instead of ECO, don't be afraid to force AC ON and turn temp down to Lo and Fan Full, It does get very cold in my car.
Lighting dark spots are present on my triple beam LED lighting system that's to help not send light into oncoming drivers eyes and not light up road signs on left side of roadway. Usually mandated regulatory concern for each country's lighting standards.
You can switch measurements under Settings General "Language and Units" turn off automatic then you can select your preferences.
You can turn off rear seat item reminder in the Settings-Vehicle-Customize-Utility Section
Exiting the vehicle when the car is in ready mode or 'ON' will give you six beeps I think, letting you know your car is still on.
If you have all your safety features turned on - you can disable them in your screen - so make sure they're on and you know what they do. While backing up if objects are detected you will get beeps and screen alerts too. If you fail to stop your car will slam on the brakes and alert you with a red coloured BRAKE notice on your screens.

I would highly recommend you read your owner's manual as almost everything you need to know is in there.

number 3 What type of headlights do you have ? I am not sure this problem exists with triple beam LED headlights.

SORRY, it looks like @TheCDN has already answered this and it is normal on triple beam. Thanks @TheCDN

YMMV,

I have the triple beam headlights and it's like a straight strip of light.

 

I have triple beam lights and I have a couple of 'dips' on my low beams. The one to the left is so as to not blind oncoming traffic, I believe the other is possibly to not blind the car in front of you.

 

The dark spot is a design feature of all modern LED low beam headlights. LED headlights are notorious for glare and blinding incoming traffic. Hence, manufacturers are required to include this dark spot in the headlight pattern to reduce this problem. It's not exclusive to Toyota. Every vehicle sold in the US during past 4-5 years has this "feature".
The only solution to this problem is adaptive headlights like the one installed on some vehicles on Europe. These headlights work in conjunction with the front-looking camera and deactivate certain parts of the light array to prevent blinding incoming drivers. What is sold as "adaptive headlights" in the US are not really truly adaptive, it's a marketing gimmick just like Tesla's "fully self driving" (which isn't fully self driving).

 

Please explain. My headlights appear to have a significant range of motion. What is different with European version?

 

Real adaptive headlights work like a movie projector with hundreds (thousands) individual pixels that can be turned on and off individually. They shine light everywhere they should, and turn off the light in the direction where it shouldn't go. What's called adaptive headlights in the US is like the 1960s technology in the Citroen DS where lights can point toward the direction of a curve.
With real adaptive headlights you get uniform illumination in the entire area in front of the car except the specific spots / areas where there should be no light, like an incoming vehicle. For example, if there is a pedestrian on the side of the road, the headlights will illuminate the legs and body, but won't shine any light toward the person's face. On the other hand, if there is a road sign, the headlights with shine more light on the road sign so that you can see it more easily. If you follow another car, the headlights will illuminate the area behind, to the sides and above the vehicle in front of you, but won't shine light on the back of that vehicle itself (it will look like a dark rectangle in the center of the beam).
Here is a short video that illustrates two examples: AUDI and Mercedes.

 

This video offers a pretty good view of the triple beam adaptive headlight system found on the NX. Depending on your countries option packages it's usually available in the upper tier models. I've used the Automatic High Beam system quite a bit while travelling at night on our trips from Ontario to Florida. The system works quite well, never having anyone flash me back because they were being blinded by my lights. It has the ability using the forward facing camera to dim the area of the oncoming vehicle so as not to blind them, while still keeping the high beam active looking straight on and off to right side. It will detect the bright light reflection of those large overhead highway signs and dim the lights. It detects you coming up to a car in front of you and dims the lights also. When you enter into a city scape with plenty of light posts and lighting from building signs etc. the high beams are temporarily turned off. They resume once you're back to dark lit roads. It was a real treat to not go through that 'high beam on - oops, high beams off' back and forth for hours on end. The car is also optioned with auto levelling headlights, turning lights as well as fogs. All are very well designed and do a great job!


The Europeans are light years ahead with their lighting!! Pun intended. They have thousands of LEDs in each lamp bezel that can be controlled with razor sharp accuracy around the outline of oncoming traffic, pedestrians, animals etc. It's truly amazing but our archaic regulations in North America forbid them still!

Sorry, but if you have 25 minutes of your life you not in need of too badly this is a great one to watch about Audi's Matrix lighting systems.
I up the play rate to 2X to get through it faster.


The boring details of the lighting can be found in section "3-1. Driving when the surrounding area is dark" around pg 194 depending on your particular model and year of your owners manual.
