Don't know about these new fangled modern cars but all the cars I've ever looked at have a
microswitch on the brake pedal which should be the only thing that affects the brake lights.

this confuses things, as the brake lights _may_ be signalled by the computer via a CAN network of
some sort...
I certainly can't help you there, but I'd check the brake pedal for a microswitch first...

if not then the dealer's the place to go...
