GX BSM False Alert Issue
Hi All,
Brand new member and I would really appreciate your feedback. My 2014 GX has been great except for one annoying problem; with BSM mode enabled, the passenger side BSM indicator randomly lights solid when driving down the road with NO vehicles around me (driver side indicator works perfectly 100% of the time). Does not appear to be correlated to temperature, day/night, humidity, speed, or conditions mentioned in the manual. Other current RX and GX owners I know don't seem to have the issue. Has anyone else had this issue and found a fix? Has anyone experiencing this done any research? Can the BSM system be calibrated or is the detection program burned into the individual sensors and control module such that the system cannot be re-calibrated? Does a GX BSM system publication exist? I have several photos illustrating the problem. Reported to dealer. The dealers conversation with Lexus was that it is not a perfect system with no explanation as to why one side would have the issue but the other wouldn't. Below is the online reference that Lexus provides. The BSM feature is a very nice one except for this intermittent issue. Thanks for your help.

2014 GX False BSM Alerting
Since my first post, I have found that I can reproduce the false alerting by driving down certain locations on some roads in my area of town. I suspect that the BSM operating frequency is a shared frequency and that the Lexus OEM supplier's system is not uniquely coded (or filtered) to exclude "non BSM" system detected signals within the shared band. Still pleased with the BSM feature (vs not having it), just reports more often than necessary. Wish I had better news to report.

Mine does this when I'm driving down a heavily forested area. It's mistaking the trees for cars. Or at least that's my excuse.
It did the same thing in my 2013 GS350.

I agree with Happytrail, I would rather it report more frequently than not have it, but sometimes, I know there is no one on my right hand side, i start changing lanes and the light goes on, and i get scared/confused for a second, as it obviously means there is something that i did not see before switching, this is mainly why I would like to have a solution.
The idea that the frequency could be shared kind of makes sense to me now, as there are certain areas when it reacts this way, could be the reason. The other reason I was thinking of (no idea if it makes any sense or not) is that the power wire might be loose, or the sensor itself might be slightly moving, I tend to see this fault when I am breaking a little harder so the car would be leaning forward.
I took the car to the dealer for maintenance and told them about this, and off course they could not reproduce the fault.
I had a GS350 and it did not react the same way.

The mirrors give you the warning light. You still need the sensors.

I wonder if one also needs a new BCM as well for this mod? Are there any configurations for system in Infotainment or center dashboard display?

Park Assist is part of it. Just a few shots from FSM.

BSM false positives
Has anyone had issues with BSM false positives? I've attached a picture. This happens regardless of weather or if the car exterior is clean or dirty. It also only happens on the passenger side. It's on my 2018 GX and I've taken it to the dealer twice now. They claim there's nothing wrong with the sensors and they're functioning as expected...

The sensors will go off on the passenger side often when you are passing a steel post such as stop signs depending on how close you are and how thick it is.
My opinion on why it only occurs on the passenger side most of the time is because we drive on the right hand side of the road which places us in closer proximity to the posts compared to the driver's side sensors.
I wouldn't lose sleep over it.

I had a loaner a couple of months ago with BSD and I found that it was very sensitive to objects on passenger side. The alerts showed up even when I was passing cars 2 lanes away.
