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 own a 2020 Ford F-350 with the 6.7L Power Stroke diesel engine. It uses the Bosch CP4 high-pressure fuel pump, which is known to be prone to sudden, catastrophic failure. If the pump fails, it sends metal shavings through the fuel system, which can cause complete engine shutdown without warning — a dangerous situation while driving. Currently, an unresolved safety recall exists that could cause additional potential damage to this high pressure fuel pump, which only increases the odds of the pump itself failing. That said, the present unresolved recall does not solve the problem of a faulty high pressure fuel pump. Ford is aware of the issue and switched to a more reliable pump in later models, but has not issued a recall or offered repairs to affected vehicles. This is a known defect that affects safety and reliability. While mine has not failed yet, many owners have experienced engine failure due to this pump, and I believe it’s only a matter of time. I’m concerned for my safety and the cost of repair if this part fails.

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.
