Metal shavings were found in my oil after the check engine light came on a day before I took it in. The day that I took it in my brakes limited the speed of my truck to 43 mph due brake malfunction. The dealership called and told me that they recommend engine replacement due to the metal shavings found in the oil. I can give more in depth info as I receive it but I just wanted to alert Chevy that my vehicle is doing the same thing that the others are getting recalled for.
