Q: Concerned with engine noise

asked by on

I recently picked up a used 2009 Toyota Corolla with 49,000 miles on it. About a month after the purchase, something under the hood began to make a kind of squealing noise whenever the car was on. Performance hasn’t changed and no light have illuminated on the dashboard. Should I be concerned or are there other warning signs to look for to find the root of the noise?
