We were driving when I made a right turn and suddenly the steering wheel locked on me and at the same time various warning lights lit up on my dashboard. The car slowed and I was able to regain control of the steering wheel to pull over. After driving a few miles further we once again came to a right turn and everything happened as before except with greater intensity. We tried to straighten the steering wheel for control and were able to pull over into an empty parking lot. By the time we came to a stop, which took all of just one or two minutes, smoke was coming out from under our hood. We quickly got out of our car and opened the hood to see the battery in flames.

I am certain if we had not had water the whole car would have caught on fire. …
