Here's the issue with your car.The problem you describe is indicative of a faulty ISM (Ignition Switch Module).This is the module you insert the ignition transponder ("key") into on the console to start the vehicle.It is in actuality a control module that serves several functions: It senses the key transponder signal and allows the vehicle to crank and start providing the signal is correct , It unlocks the steering column lock during startup and driving (your error code) and it supplies keyed and accessory voltage feed to dash,instrumentation and interior components;as well as all other ECM and vehicle power signals.When these fail(quite frequently I might add)you get the steering column failure message as well as dash illumination and instrument failure.This is very common and needs to befuddled next . Hoped this helped. Positive feedback and bonuses Greatly appreciated.

Ok this means you will need to replace the Ignition switch control module to fix the issue . Eventually it will fail .

Would run about 250 parts and labor at the dealer.
