I am going to take it to a different dealership. I can't see what oil filter it currently has on, but I would assume that since it was certified by the dealership they would've changed the oil there and put on the correct oil filter. But who knows. The oil filter should be an acdelco PF26 is that right? This noise is not normal and it doesn't take a a rocket scientist to figure that one out. I will take it to the other dealership in town and see what they say about it.
Thanks for your help!
