The BSM is not dependable enough to go without conformation by viewing traffic in the mirrors.
Over the years I have dealt with many BSM complaints of false warnings or failure to warn. There is a page in the owner's manual with a long list of conditions in which the BSM may not operate as desired.
My 2024 RX 350h has audible blind spot monitoring. Can't imagine anyone not looking in their side view mirror before changing lanes.

Well gee @Freds430 what the heck does 2024 RX 350h audible blind spot monitoring have anything to do with NX blind spot monitoring and NX's lack of audible warning ? It seems like you like to continually rub this fact into the face on NX owners. This is not very nice.

Let me restate the problem. On 3-5 lane highways in Florida, cars frequently approach you from behind at ~100 mph which gives little time to react when you want to change lane, even if you turn the turn signal on. Monitoring a bleak blinking light on left or right mirrors for blind spot vehicle is problematic within split second, you need an additional confirmation such as acoustic signal. My old Mazda CX-5 gave me this functionality and I have never had a safety near miss on the road. It's beyond me why Lexus NX doesn't offer this critical safety feature, even though the signals required are already wired and available, and all it takes is to add an extra programming line. Among the others, NX gave me the Stop-and-Start function that I can't permanently disable (turning-off A/C when at red light, in FL, for my good of course :-), but not the critical safety feature required. Add to this another NX features such as auto-high beams under cloudy sky that blinds the cars directly in front of me on highway. All B.S. for the masses.

Did it ever cross your mind that it might just be that I am conveying to the OP that if it is available for the RX then Lexus has the ability to put in in the NX. Why is everything with you a pissing contest. SAD!!! I have posted this to you before a continuing problem with you that guessing you just can't control.
My mature side is telling me not to say anything else.

I did NOT take his comment as a slight on the NX model (or owners) in any way. I actually appreciate hearing about some of the differences, because it tells me what may be available in future generations of this model. As Freds430 owns both models he is in a unique position to offer this sort of comparison.

Here's another thread that started in May 2023 on same subject. Post #50 states: If you have LDA (Land Departure Assist) you can set it with an audio alert. This will sound if your turn signal is activated and the BSM (Blind Spot Monitor) detects a vehicle in the adjacent lane. It will also alert you if you stray outside your lane markings. (p 817 of the 2025 PDF manual)

This is the way to get a beep in combination with a light on mirror. It's technically an improvement over the old way. You now get a steering correction, a beep and a warning light that all combined is trying to get your attention of an impending collision if you proceed and change lanes.

I've travelled on US highways for over 40 years at triple digit speeds at times to go along with the flow of traffic. There's nothing that is more thorough and decisive than turning the human head left and right, using two eyes and head adjustments to know almost 100% what's around you and to determine how fast the object is coming up on you. Ask a race car driver, ask a seasoned trucker, ask a cop, ask a motorcycle driver. There's more and more idiots on the road today, in fact there's more elderly drivers too, hell I'm almost in that camp myself. I'm perfectly comfortable to ignore a blinking light and a beep, I'll confirm with my own two eyes quickly and adjust accordingly. Safety systems are flawed at times and operate very simplistically.

Read up on Tesla's resistance to using LiDar instead of sticking with Radar on their very expensive optional "Full Self-Driving (Supervised)" feature design.


Here's how you should setup your side mirrors. Many people adjust them so that they can see the side of their car. Well I'll bet you no one has ever had their own car hit them! You should adjust them to see the lane beside you so you can spot a vehicle sooner that is approaching your side of car. The SAE approves this method as it will eliminate almost all blind spots when used in combination with your rearview mirror. Interestingly I have been doing this since I learned how to drive and every car I've gotten into clearly does not provide sufficient adjustment in their side mirrors. Once the adjustments are made you'll notice the mirror is almost out of travel to accomplish this. Engineers who design mirrors don't get this right!

The current gen5 Toyota Prius ( 2023 - current) has this feature, audible blind spot monitoring. I don't think the Lexus NX is going to add this feature in the future.

Come on Fred not a pissing contest, just your devil's advocate when you get the information wrong or post it in the wrong forum or post the same information again and again.. I am so glad you are mature.

Thanks by your immature post confirming my point.
You are a right fighter. Must be a horrible life. This is a car forum. Chill out take a deep breath and grow up.

Moderators one of you posted awhile back how you can block someone's post. Please re-post. One immature member should not spoil a great forum. This guy is nuts. Read some of his post in these threads. It is the same antagonist attitude on so many of his post.

Oooof... You can ignore each other. You can also click on the user and ignore them.
As far as you two go... You can stop going at each other. (I don't care who started what)

Reread the first post and my first post. I was telling them it is available on the RX and should be an easy fix. There is no doubt who started it. It is his MO. I will mute again immature bullying post. Thanks for the info. I just put him on ignore list. Sad that on a automobile forum one has to be ignored.

If you re-read my post, you will understand that I don't need to re-read anything.... as I do not care who did what.
Sensationalism and drama aside. Move on... Someone doesn't like what you said. They said something back. Who cares? Random people on the internet talk crap. Push buttons and "Troll" away. You can ignore them or set the forums to ignore them for you. Words on a page, from randoms in the wild.

Now, Carry on.

Thank you for your comments and dedication to the problem. I've been driving cars for 57 years now on the North American and European roads and know how important it is to get a feel for local traffic. Florida interstate highways around metropolitan areas aren't what they used to be even 15 years ago and require concentration and reflex of a race car driver. In dense traffic, spending ~40% of the time, observing behavior and predicting trajectories of the others behind in 3 mirrors may still fail, as some/few drivers drive 30 mph faster than the rest and rapidly hop lanes. Any additional means (like a blind spot beep) improving situation awareness is a huge safety plus.

That takes me to the LDA confusion, at least as it's observed in my 2026 NX. If set, LDA may beep when changing the lane but doesn't work in a predictive mode, namely, that when I turn light signal on w/o changing my lane yet, I don't get a beep warning about an adjacent car that just entered into my blind spot zone. In other words, LDA warns about lane change irrespective of the blind spot situation. But that's what my old Mazda and many domestic makes can do for quite a few years.

As configured, Lexus NX LDA may contribute to driving hazard. While entering highways via ramp with gradually merging 2 lanes, I encountered an unexpected jolt on my steering wheel and sudden deceleration, exactly when I should be accelerating to highway speeds, e.g. 65 or 70 mph. It looks Lexus designed this "safety" system for sleepy country roads, not contemporary highways and metropolitan areas. Fixing these safety issues is quick, cheap, and easy by adding a few programming lines to NX computer code, and that's what a responsible corporation should do if it cares about own customers.
