Keyless entry security when you turn it on the headlights doesn't blink. On the dashboard "security" word is flashing. It wasn't there before.
Headlight lenses are fogging up on the outside lmiting the amount of light radiated at night. I have checked numerous other similar model cars and they all have the same problem in some degree. Subaru refuses to take action under the warranty and maintains that the problem is "normal wear and tear in the environment". I maintain they selected an inferior plastic for the headlight lenses. I know that Subaru is aware of this problem because "lenses" are specifically excluded under all the extended Subaru factory warranties they offer.
