There finding was that they found coolant leaking from the lower intake gasket. I could not get the repair done because of two reasons. This is my only form of transportation and money is scarce since I am a full time college student and mother. I have had many gm cars with over 100,000 cars before that never had this problem. I voiced my frustations to the manufactuer, who just simply stated tough luck. The dealership refused to give me an extended warranty above the intial manufacturing warranty.
