GMC pickup developed coolant loss. Took in and found that head had cracked. Service bulletin revealed 50% of heads for that year came from one manufacturer and had been prone to cracking. Discovered mine indeed had the suspect head and did have the crack as described. Why didn't GMC issue a recall on these and save me $4,000?

Purchased a used 2005 GMC Sierra from a GM dealership. Two months later the engine was found to have a blown head. After doing my due diligence, I was made aware that GM has had major problems with the head casting manufacture of my particular truck. I am having it repaired at a GM dealership and have asked GM to assist me in anyway with the costly repair, since it is only a 2005. They were not willing to work with me in the least. The GM mechanic even stated that these particular heads are notorious for cracking and GM is aware of this.
