Vehicle is equipped with an auto start/stop feature. When stopped at stoplights, intersections, etc, the vehicle engine will turn off. When driver's foot is removed from brake petal, the engine reactivates. However, on numerous occasions, the power steering did not reactivate until 1-2 seconds after the engine restarts. This left me with no control of vehicle steering (as I was unable to easily turn the steering wheel). This resulted in several problematic incidents where, for example, the engine disengaged while I was inching into a left-hand turn through an intersection. When I attempted to then start my turn, the engine re-engaged, but I was unable to turn the steering wheel, causing me to drive forward (toward oncoming traffic) instead of being able to turn the wheel left to complete my turn. Similar events have happened on several occasions.
