From What I was told by the service tech was they weren't allowed to investigate the problem with my oil pump, GM Canada wanted them to ship it to them without even looking at the reason for failure. The invoice says that the pump was internally damaged. It also states that they had numerous cases of failed oil pumps. I was also informed that there was moisture in the oil.

Is anyone else having issues with their oil pump failing, my oil pump recently failed on my 2014 Denali with a 6.2l
