Stability Control: Ya it stinks that they didn't include it. Ditto the steering wheel audo/climate controls. It's just cheap and stupid not to have it at these prices and it's something I simply had to deal with.
The reason stability control is not included deals with engineering problems encounted with the hybrid system and Ford's AWD system.

You can read them here:
Ford stated they have a problem combining the hybrid braking system and electronic stability control. This is the reason the hybrid lacks electronic stability. Read it here

The Toyota Hilander Hybrid has a different AWD system (rear electric motor for rear axle propulsion)

than Ford's version which is very similar to the Haldex AWD system.
