Funny you should ask about kayak racks today. I just took my CX-5 into the local Mazda dealership today to show them four large dents that a Yakima Q Tower kayak rack put into the roof rails (the painted metal running along the sides of the car above the doors). While my Yakima rack did not do any damage to a Saab hatchback for the 8 years I used it on that car, by the time I'd used the rack on the CX-5 to haul 2 kayaks on vacation this summer, I had the aforementioned 4 big dents. The rack was properly re-outfitted to fit a CX-5 (I called Yakima directly for the parts list). I'd never had problems before and didn't think twice about using the rack on my new CX-5. If I were you, I'd look into racks that use the grooves on the roof (if you didn't buy the Mazda roof rails). Ask manufacturers LOTS of questions, and don't get the kind of rack that clamps on. The CX-5's thin sheet metal doesn't hold up. My repair bill for taking out the dents and repainting the quarter panels: $1,700, plus cost of the rack parts I bought to retrofit my Yakima rack and the cost of buying a new rack that won't dent. Total: about $2,400.00.
