   After the car was started, I drove 3 houses over when there was a loud knocking sound and the car just shut off. When trying to restart it wouldn't and the check engine, battery, and oil lights came on. After pushing it out of the road we checked the oil and it was empty. The oil has just been changed less than 2 months ago. Now the engine is seized.
