My brake pedal is very spongy and my ABS light is on ? on 2005 GMC Sierra 1500

Front wheelbearings , brakes and calipers have been replaced in the last 2000 miles.

could be air in the system causing the spongy pedal. you need to have it re checked if a shop performed the repairs.
the abs is a system failure. the code needs to be pulled to see where the failure is ocurring.

Bleed front brakes, this should fix your problem.
