The water pump is an electrical component now and is controlled by the engine computer. It only works when it has to, including even when the engine is shut off. This reduces fuel consumption and has less parasitic drag on the engine. Failures are usually caused by the electronics inside the pump so there is almost no warning of an impending failure or early signs of overheating. One of the only warning signs of electric water pump failure is if the electric fan suddenly starts working all of the time at its highest speed. This is because the pump has stopped, or not responding, and the fans are kicking in to take up the slack. Depending on operating conditions you may only have minutes before the engine shuts off to prevent serious overheating.
