Weird Brake Pedal Issue
My 2013 AWD Tech has this weird behavior. When stopping on an incline at a traffic light (shift lever still in D of course), many times the brake pedal becomes very stiff and feels as if the engine has been turned off. If I release the pedal, the car wouldn’t move. Pushing the gas pedal, the car moves forward and the brake pedal immediately returns to normal operation. Is this some kind of safety feature to protect the transmission in case lazy drivers take their feet off the brake pedal when stopping on an incline? I bought my car in August 2012 so need to know if this is a defect as warranty is running out in a few months. Thanks for any help/advice in advance.

Hill Start Assist
New for 2013 is hill start assist (HSA) that helps prevent the RDX from rolling backwards when the driver switches from the brake to the accelerator while the vehicle is stopped on a hill. When the road incline exceeds a 5-percent incline and the vehicle is fully stopped in any forward or Reverse gear (with engine torque holding the vehicle), HSA self activates. The hydraulic brake modulator is controlled by a longitudinal g-force sensor along with a wheel speed sensor and steering angle sensor.
When hill start assist is active, the brakes momentarily hold as the driver's foot lifts off the brake. The brakes are automatically released when the driver presses the throttle, sufficient drive torque is applied, and the vehicle begins to move forward.
