I have the 7.3 gas engine. It is now sounding like a typewriter. I've been told I could have a $8,000 to $13,000 repair or total engine replacement. My truck is just under 97,000 miles and this has been a known issue for the Job 1 engines. Ford is not taking ownership of these lifter/cam issue. I was told I could have my engine lock up on me while driving. I am autistic and have an autoimmune issue that cause me to have a disabilities. It does not seem right, that a long term, multiple Ford owner now could have their engine fail or lock up while I'm driving, not to mention I may need a complete new engine from this design error. From what I've read, the Job 2 of these engines they've enlarged oil recyclers or something to correct this issue. Can you help us that have this major saftey issue?

I have sent in a previous complaint as our truck would die in the middle of the road, due to the fuel pump. It is unacceptable that Ford has not resolved the recall issue in 9 months. Our truck is needed daily for our business. Please make Ford take action.

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.
