Hey there. This is something your car will do when going into "safe mode" which can happen when the ECM detects something is wrong with any of the car's systems. This is a safety feature to keep you and the car safe when things are not operating properly. If the car is going into "safe mode," then it this is a good indicator that one of the systems is going bad and is in need of urgent repair.
