tHIS IS THE SECOND TIME IN 3 YEARS THAT THE COOLING SYSTEM FAILED. i BOUGHT THIS CAR IN SEPTEMBERT OF 2009, AND HAD TO REPLACE HE HEAD GASKET DURING THE SUMMER OF 2010. Now i get a check enging ligfht and when i bring it in the heads are already cracked! It seems like this vehicle had a design flaw that causes head gasket failure and fatal over heating fairly quickly. I have heard that there are intake valve problems. Could this result in head gasket failure?? Why wasn't I notified about the intake valve problem?? Pontiac/GM never ever notiofied me that this might be an issue. I had to find the info myself via the internet.
