Was approaching a red light and applied pressure to brake pedal. The brake pedal has hard and wouldn't depress. The abs and traction control lights came on and the vehicle continued through the red light. Fortunately there was no one in front of me or any cross traffic. Releasing the brake pedal and reapplying with the abs and traction control lights on the vehicle was finally able to stop. Carefully drove the vehicle home and had it towed to the dealer the following morning. Dealer diagnosed it as the front hubs being defective. The hub bearings were so loose that the abs sensor and speed ring were not in close proximity to each other. Dealer replaced hubs and vehicle is now functioning properly.
