Hello Greg, thanks for reaching out. The short answer is yes, it definitely should. The Thule Motion 3 Low Profile Rooftop Cargo Box # TH37PN fits crossbars up to 90 mm wide (3.5 in) and up to 30 mm tall (1.125 in). The Lexus OEM crossbars are under these dimensions, so clamp fit will not be a problem.
The cargo box requires the crossbars to be 21-7/8" to 36-5/8" apart. I was not able to find this spec online for the Lexus OEM rack but I would be pretty surprised to hear they do not meet this spec.
Also, the distance from the front crossbar to the line where the roof and the hatch meet must be at least 52". This is to ensure the hatch can open fully without contacting the box.
If you can check and verify these measurements you can be absolutely sure the box will work without any clearance issues.
