Hello Jordan, thanks for reaching out. In order to use the Thule Motion XT Rooftop Cargo Box # TH629806, your crossbars must be between 23-5/8" and 36-7/8" apart. Also, for the hitch to fully open, you must have at least 51-1/4" from the center of the front crossbar to the line where the roof and the hatch meet.

How far apart are your crossbars?

Hey Jordan, did you get a chance to measure the spacing on your Sorento’s crossbars for the Thule Motion XT box? Once you know that distance, it’ll be easier to confirm if the setup will clear your sunroof and hatch. Let me know what you find—I’m here if you need a hand narrowing it down.
