2005 Honda Pilot lighting problems

Tl* the contact owns a 2005 honda pilot. While the vehicle was parked and the headlights were activated, smoke appeared behind the steering wheel. The contact stated that there was an abnormal burning odor when the head lamps were activated. The vehicle was taken to a dealer where it was diagnosed that the headlights failed and needed to be replaced. The vehicle was repaired under NHTSA campaign number: 12v136000 (exterior lighting); however, the repair failed to remedy the vehicle.

My wife called me one morning on her way to the shop. She was frantic saying "my steering wheel is smoking. I don't know what to do. I'm just about a minute from the shop. Should I pull over or just try to make it to the shop?" I told her, if it's not too bad and she is that close just keep coming unless it gets worse. When she made it to the shop, I pulled off the plastic cover around the steering column. And found the yellow wire going to the headlamp switch burnt.
