So we just bought a brand new 2025 yukon XL AT4 with 3.0 duramax a week ago and we took a small trip. On our way home we lost oil pressure and spun the thrust bearing. Its in the shop cab off getting a new motor as we speak. It had 1036 miles on it. The dealership has been awesome! But im not happy with getting 1k miles out before chucking the motor. Then they found transmission cooler lines rubbing so they are also replacing those. Any thoughts? I heard problems with the motor but 1k miles and transmission lines rubbing. The dealer has been sending me pictures every day with updates.
