    Have you checked / replaced the front wheel bearings / hub assemblies - due to wear? The other possibility is the front disc brake rotors are warped - fairly common. If the front rootors are replaced, they are fairly inexpensive; try the many on-line auto parts sources, such as; www.autopartswarehouse.com or www.rockauto.com. They (Rock Auto) list the front brake rotors from around $14.00 each for your vehicle.

    Did you ever figure out what was going on? I have a 2009 Optima LX (just turned 55k) and it has recently started doing the same thing. You apply the breaks and shortly after they grab again. This usually occurs when the engine is cold. I have noticed that it will happen (randomly) when I apply the accelerator. The dealership has not been able to find the problem. I'm wondering if it might be something with the ABS...
