It never lost oil. I have the old oil in an old 5qrt oil jug and it’s almost full. There was a small leak at the turbo in-feed line going into the oil cooler. when I went over the car. To see if I could see anything obvious. I just know when it got the low oil pressure warning the motor ran really rough. Just really weird how it didn’t throw any codes or any warnings before hand. When I drove it home from the body shop. I moved it when it snowed to plow out my driveway. Never showed any issues. Gm is no help. Talked to the gm senior advisor on the 1800 number he said I really have no options now that the bumper to bumper warranty is out. He said the dealer already got in contact with him and there’s nothing they can do to help. I’m not paying 780.00 for them to take the motor apart when I can buy a used one with less miles for the same price. I think gm has the worst customer service and I will never buy another gm vehicle again.
