This morning after driving my car and returning home, my car won't start and it clicks. The dash has ABS and ESP Currently unavailable. What could this possibly be?

You are out of battery power! Either battery, alternator or voltage regulator is dead. My suggestion is to start with the battery if it is several years old, and then move on to the voltage regulator and alternator.

Once you fix the voltage supply issue, you may still have the "ESP Unavailable" message. If so, you need to recalibrate the steering angle sensor by starting the engine, sitting in park, and turning the steering wheel fully lock to lock a few times until the message clears.
