This Box was installed on 2014 Jeep Patriot Latitude. The build quality is excellent, and the installation was quick and easy. We are very happy with this purchase.



by:

The locking mechanism does not work consistently. Once I get it to shut whenre the lock will engage, then I can't get it to unlock. On my trip to Breckenrige last winter to ski it was very frustrating and a little concerning that I could barely after 10 minutes of working with it to lock into place for my trip home.....last week I tried it again to see if it would work any better for my upcoming ski trip in March, and I can't get it to lock into place at all and haven't been able to.....probably can't use it again. for the ~ $1200 price I thought there would be a better locking mechanism that was dependable



by:

Love having the extra space



by:

I like the open from both side feature and the improved positive locking feature this has over an older unit I had.



by:

Lots of room, remember that you have to store it

  • Will The Thule Motion 3 Cargo Box Fit A 2016 Honda Odyssey With Factory Roof Rack?

This box is designed to fit virtually any crossbar regardless of shape, and the Honda factory bars are no exception.

  • Longest Roof Rack Crossbars for a 2002 Toyota Sequoia to Carry a Thule Roof Box and SUP Rack
    I'd be happy to help, Ray! If your 2002 Toyota Sequoia has factory raised side rails that run from front to back like in the photo I attached , the longest crossbars are the Malone AirFlow2 Roof Rack, Part # MAL24AR. They have 65 inch long crossbars. I actually use a Malone Rack myself and it works well for me. The one thing to keep in mind is the width of the accessories. The largest Thule roof box we carry is the Thule Motion 3, Part # TH39PN, and it's about 36 3/16 inches wide. The...

  • Will Thule Motion 3 TH39PN Fit 2024 Subaru Outback Wagon?
    Hello Leigh, thanks for reaching out. The Thule Motion 3 Rooftop Cargo Box # TH39PN can indeed be used on a 2024 Subaru Outback wagon. This box will fit virtually any crossbar shape, including round, square aero and most factory crossbars. The only real requirement is your crossbars must be spaced between 21-13/16" and 36-9/16" apart. I am not sure exactly what crossbars you have on your Subaru, but they definitely should meet this specification. If so, you are definitely good to use the...

  • 2025 Toyota Sequoia with factory roof rack and crossbars
    Yes, it will Tim. The Thule Motion 3 Rooftop Cargo Box item # TH39PN will indeed fit the factory crossbars on your 2025 Toyota Sequoia. You will want to make sure your crossbars are spread out between 21-13/16" - 36-9/16" apart so the mounting clamps at the bottom line up. What do you plan on putting in your cargo box?

  • Can Thule Motion 3 Roof Cargo Box Fit 2024 Honda Pilot Trail Sport
    Hey Brian, yes the Thule Motion 3 roof top cargo box part # TH39PN will fit and work great on the roof of your 2024 Honda Pilot Trail Sport. Basically any roof rack we offer that fits your vehicle will also work with this box but I really like the Thule Evo Wingbar roof rack part # TH46DS or if you prefer a flush bar setup that would have a more OEM look we have the Thule Wingbar Edge part # TH74DS as well. What are you planning on carrying in the box?

  • Will the Thule Motion 3 Rooftop Cargo Box Fit a 2020 Chrysler Pacifica
    It sure will Bryan. The Thule Motion 3 Rooftop Cargo Box item # TH39PN will attach directly to round, square, aero, elliptical, and factory crossbars. You will want to make sure your crossbars are spaced between 21-13/16" - 36-9/16" so the mounting clamps connect properly. This distance is measured from the front of the rear crossbar to the front edge of the front crossbar. What kind of gear do you plan on putting in the cargo box? You can add this information, along with any other questions...
