Update: Steering angle sensor not faulty but they could not calibrate it. Turns out the SZL module is bad (control stalk assembly) and causing a road block in the communication bus (fiber optic, CAN bus?). So, bottom line, labor no charge but they are charging me $775 for the SZL. If I purchased the part, it would be about $575. I suppose this part could explain the turn signal not self cancelling.

Dang dealers.
