RUN to the Dealer (it IS in warranty isn't it) and beg,cry,scream until they fix it for good. You don't want to know what it can cost.

It may be as simple as a G sensor wiring problem--or ?

BTW, You WILL have serious wiring harness problems soon on the electronic throttle acutuators, the fuel injector wiring harness, the main wiring harness, and most all other underhood wiring.
