Was driving and all of a sudden steering power low came on and engine died, got stuck in a busy intersection and needed assistance from police officer until I could be towed. Steering did not work to push car to side of the road so I was stuck in the center of the traffic. There was absolutely no lights or warnings before the steering power low and it died. Could have been very dangerous, I am supposed to drive north through the mountains to go camping in 2 days, lucky it didnt happen then. At the mechanic now and they jumped the battery and say its working fine and they cant find the problem.
