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.
