Frequently asked questions

Can’t find the answer you’re looking for? Reach out to our customer support team.

I'm interested in the Thule Motion XT XL, how can I tell if this box is too long for my car and interfere with opening the trunk on my hatchback?
To determine if the Thule Motion XT XL fits your vehicle without contacting your hatch, measure from the center of your vehicle's front roof rack crossbar to the seam where the roof meets the hatch/spoiler. If this measurement is greater than 51 1/4" then the Motion XT XL should clear your hatch just fine.
Is there a way to secure cargo inside the Thule Motion XT XL?
Thule provides a set of cargo straps to be used with the anchor points found inside the Motion XT XL to keep things secure while traveling
