This morning while turning the truck on I got a message on my dash "Brake System Failure, Top Speed 45mph" And the engine wouldn't start. Tried again and now nothing comes on, no infotainment, can lock or unlock the truck, nothing on the dash.

Sound like a dead battery or something else?

Nice - one year old vehicle - to the dealer for warranty care

 

Nope. Just a dead battery. All my fault
