I have a 2010 Hyundai Elantra with 43,000 miles. I am getting a "squealing" noise lasting about 10-15 seconds on starting the car, but it is not consistent.

accessory belt might be slipping, with engine off check for tightness, look for cracks in the ribbed side and wear on the flat side

answer above is a good one. make sure oil is not getting on the belt or belts. i don't know if this motor has more than one belt but it is a belt too loose.
