When steering wheel is at the full right or full left position,
I hear scraping sound.

When I turn the wheel a few degrees so that it is no more at the extrem left or right position, the noise disappers.

It picked up the car from dealer yesterday. The dealer did the following:

if the steering wheel is tapped or hit or roads are bumpy, steering wheel makes metalic rattle noise.
REMOVED AIRBAG AND SECURED STEERING WHEEL


The rattle sound disappeared after dealer fixed it, but the "scraping" sound came new after dealer fixed the "rattle" sound.

Power steering fluid is between min and max.
