engine coolant leaking and coolant bubbling in reservoir
The truck has only 121,377 km on the diesel engine which is just outside the warranty window by 3.5 months. This is a known problem to General Motors and they have issued a bulletin to GM service centers to replace both head gaskets, but hasn't issued a recall to date. The truck owner's are left in the cold when their outside the warranty window which is a substantial cost of approximately $7,000.00. The purchase price of these trucks was in the $70,000 to $80,000 range in 2011. General Motors needs to take responsibility for substandard components on their vehicles and repair such issues at no cost to the owners. I am one of many GM owners that request that GM stand behind their product and make things right.
