I stopped and the engine stopped. Seeing an obstacle ahead I turned the steering wheel and lifted the brake pedal at the same time. The steering wheel wouldn't turn. I had time to realize the Power Steering was off before it came on. I did a few tests. Does this every time. There is no steering servo action until after the car is going forward. The engine is fully running and the car moving before the steering turns on. This unnerving detail would make some sense if the steering was run by an old school belt driven hydraulic pump, but the steering is electric. It could be on but it is not. I'd like better it if a yank on the steering wheel started the engine, but it does not.
