“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.

“I took My 2012 GMC Sierra with 112,410 miles in for annual safety inspection and was told that my frame has a hole in it and is cracked, hence un-inspectable in the state of Vermont. I then took it to a welding shop to get an estimate on repair and the tech told me he sees this all the time on this era GM/Chevy trucks. This is clearly a widespread incident and GM should be held accountable like Toyota was years ago with its bad frames.O”Owner report · Structure · Jan 2023
