2012 GMC SIERRA 1500 Electrical System Problems

P0521 has been addressed/replaced almost nine (9) times. “Low Oil Pressure-Stop Engine” is another one that is not completely functional. The truck is using oil but we cant find evidence of leakage. Services performed at dealership or certified shop. Troubleshooting was performed, Im told. I cant vouch for the quality of the workmanship. This should not be an issue at this mileage 100,100 ohe hundred thousand miles and oil components going bad is not good. GMC has sold me a truck that needs a new engine component. Please help.
