Just had this happen to my 2019 GMC crew cab elevation tonight. Truck's screen said no oil pressure stop truck immediately. Spread oil for a couple hundred feet then came to a stop and dumped out the rest completely. Absolutely no oil left in the engine, we checked the dip stick. My entire cab actually filled with some smoke, so not sure if any damage was done. I am in Alberta Canada. My truck has 26,000 kms. Just had an oil change done 1500kms ago, all services done by gm. Guessing its the cooler hose as well, we will see come Monday. I will be pushing for further tests to be done in the future if they just replace the hose and oil.
