According to the photos in the installation instructions for the Curt Trailer Hitch Receiver # C29VV it looks like the receiver sticks out just a little from the bumper.
The center off the hitch pin hole is 2-1/2" back from the front face of the receiver (see attached). view full answer...
The Curt Trailer Hitch Receiver # C29VV will definitely fit your 2024 Lexus RX 500h and you'll still have the kick sensor functionality. Just know that you'll have to kick to either side of the receiver instead of "swiping" your foot under the bumper for the sensors to pick up your foot movement. view full answer...
I can tell you John, I had the same concern when I installed a receiver on my Acura RDX. While my receiver did not entirely prevent the use of the kick sensor for the hands free liftgate it did limit the area I was able to kick due to the receiver. You will have the same issue on your 2024 Lexus RX 500h. Once you install the Curt Trailer Hitch Receiver # C29VV you simply need to test different areas around the receiver to figure out which area works best for the kick sensor.
