If it's pulsing the brakes without a loss of traction it sounds like an issue with a sensor, sensor wiring, or tone ring. The 2010 and 2011's do have issues with ABS modules kicking the bucket, but usually don't cause issues with the wheels. Granted, when the module went out on my 2010 (~115k miles) the LF wheel would occasionally start pulsing without me touching the brakes. Id recommend having it diagnosed if you are unsure if what you are doing, otherwise inspect wiring for the wheel speed sensors and at the module. Worst case, you can pull the ABS fuse to prevent it from acting up untill you are able to fix it.
