My 2021 Ford F250 super duty pickup truck experienced a catastrophic failure of the Bosch CP4 high pressure fuel pump. This has been confirmed by the dealer's service center. As a result of this part failure, metal shards were introduced into the entire fuel system. This now requires the fuel pump and the entire fuel system (every component) to be replaced. My truck has 74,9xx miles. This is a known and well publicized issue. Rather than recall the high pressure fuel pump, Ford instead issued a recall (24S78) to reflash the PCM software with the intent to reduce the risk of the fuel pump failure. I had the 24S78 recall work completed, and my fuel pump failed still. No indication in advance of this failure.
