Steering wheel locked up while driving and no acceleration

You might have a problem with a power steering pump seizing up and bogging down the motor. Then again the steering locking up and loss of acceleration may not be related, you may have multiple problems, but there's no way of knowing until you get it to a mechanic for an inspection. If you can't drive it safely get it towed. Loss of steering can easily put you in an accident.

I parked the car and now can't turn it on

So what was the final verdict? My daughter called me tonight and said this happened to her. She almost hit another vehicle head on, thankfully the other car was took the ditch. I’ve never heard of these symptoms simultaneously. I thought she was exaggerating until I read this. Now I’m concerned.... very concerned.
