The engine failed on our 2020 F350 at 75,989 miles of normal usage. We only purchased this vehicle used May 2, 2023 from a Ford dealership in Michigan and drove it 5K miles when the check engine light came on. It is currently AT the Ford dealership in Olympia Washington getting a new engine at a cost of $13K. Per the Ford service representative in text, the issue was "There is internal damage in the motor and metal in the oil from the camshaft being damaged." We were told that an engine valve failed, the initial error code was P03035. We are understandably very frustrated that such a young truck/engine failed.
