You make good points zbigzbig. I really don't see, as do most others as well, Toyota / Lexus as a leader in technology advancements. They study, test, develop, plan for the future, but don't typically come out with new tech that others others haven't already been using. That's what results in their car designs having fewer repair issues and lasting so long. But, I really can't see their logic, as you have pointed out, not to trigger a beep combined with the light for the BSM system other than they can say the RX has it because you pay more for an RX, when other non premium cars have it.

I also find all of the beeps that do occur are really not that loud at all, in fact I frequently can barely hear it with the music playing or the windows down. Why not cut off the music completely not just lower it, so that you can here it. All things considered there's just too many beeps being used.

I believe the auto stop feature you mention is mandated by regulations, if they put one in place, you can have a button to defeat it. But it must reset every time you start the car in order to qualify for a better EPA rating for fuel efficiency.

 

If there was a beep whenever a vehicle entered the blind spot area this forum would have hundreds of posters asking how you turn it off.
I can't think of anything more annoying than the car beeping at you every time the blind spot indicator was activated. On busy motorway run it'd be torture.

 

A bit off the subject, my 2022 EU Mazda CX-5 (Homura trim) also has the same Stop-Start feature, but when A/C is on, it's automatically disabled. A more reasonable logic than in my 2026 NX, where once activated on red light, Stop-Start kicks-off A/C.

 

Yes, no EPA regulations in Briton and EU or anywhere else, except Canada typically accepts EPA compliance regulations so we have it setup as such on cars in Canada.

 

If you set up this feature "Ignore List" on your profile does that keep him from seeing your posts? Cause I don't want him seeing my posts and continuing to talk smack about me. Then I would be oblivious to his antagonistic responses to my comments. The guy is a real Ice Hole to many and seems to run unchecked around here.

 

Sometimes the truth hurts.

@zbigzbig I completely agree with you. It would be a simple programming change, a line or two of code.

We have similar fast traffic in 4 or 5 lanes in Houston; changing lanes can sometimes be dangerous.

The Lexus NX 350h does not have an audible warning. To me, this is an oversight because, as others have mentioned, the RX provides this feature, albeit, a more expensive Lexus. Also, Toyota in some of there are some models, a specific example, the gen5 Prius ( year 2023 -present), which provides a visual warning ( not too obnoxious ) and becomes a visual and audible warning both when you have your turn signal on. This, to me, is the ideal solution.

Sadly, the gen2 NX (years 2022 -present) doesn't have this feature. The newest NX software update 2320, June 2025, does not contain any blind spot monitoring update. IMHO, I don't think NX is going to change their current BSM to add audible when the turn signal is active.

They are not going just change or add anything new on a 5 year old car. When they are going to do a refresh next year, that is if they do, new and refreshed 2027 car may have new and improved system

 

After just spending over $50k on a brand new, "luxury" NX350, I don't care what "they" will or will not refresh in the 2027 models, esp. that we're talking about adding mere few programming lines to enable the audio-warning of blind-spot vehicle. Moreover, I'm willing to spend extra few hundred dollars at Lexus shop, if that's required, but this safety upgrade is critical on the roads I'm using. Customer loyalty and good will are built and may last only on this type of cooperation.
