This actually has nothing to do with warped rotors. I had the same problem with an elderly BMW that had to sit out in the rain and snow for a couple of months. When I started driving it again, it had the same issues as the CR-V. The dealer wanted to replace all four sets of pads/rotors ($$$$$). I declined and pulled the rear wheels myself. What had happened is that the pads had been stuck to the rotors for quite some time and left a high spot of brake material on the rotor(s). These rotors were not designed to be resurfaced and had quite a few miles on them so i just replaced them (and the pads as long as I had the wheels off).
After going through this I found out this is not uncommon but it is almost always diagnosed as "warped rotors" which it certainly is not. Since the fix is the same most people don't investigate further which is why it's not a common diagnosis.
I don't really see this as the dealer's fault. At worst it's an arguable design flaw. Also, using the OEM parts would be the smartest thing to do. In my case it was only an extra $40 over the non-OEM parts that got crappy reviews. Good luck!
