I don't consider the Curt Trailer Hitch Receiver # C29VV as a concealed hitch since the cross tube is still visible below the vehicle fascia. Currently I do not see that we offer a receiver with a fully hidden cross tube or removable receiver for your 2024 Lexus RX 350h.
With having the rear sensors for the park assist when you have a trailer or hitch mounted accessory it is most likely going to set off the sensors. Your owners manual or dealer should be able to explain what you can do... view full answer...
