Does anyone have problem with push start, engine jerk while starting.

This occur the second time.

Step on brake (wife said pedal a little bit hard to push than usual) press on push start and engine kind of jerk a little bit but continue on to start.

got home and turned off , and restart everything is OK.

When the engine "jerks", does she feel the brake pedal move slightly? Your comment that the brake pedal feels different leads me to suspect the power brake booster vacuum reservoir is empty.

I agree - the other thing I'd add is the possibility of there having been tension against the wheels that caused the steering wheel to move once the PS pump started.

I've never experienced anything odd with my '07 push-to-start.
