Engine loss of power - engine failure. My vehicle was serviced regularly with Ford dealership. Just weeks after an oil change at dealership I had sudden catastrophic engine failure. They found metal in my oil and stated my engine had failed due to faulty pump. I contacted ford dealership and customer service center, and they refused to repair as I was about 125864 miles (25k over warranty) on a truck they told me would last 400k with proper Maintenace. I have been making my monthly payments on this large paperweight and now there is a recall, and I still cannot get ford to repair the vehicle
2021 Ford F-250 SD engine complaints

The exhaust manifold bolts broke and it’s leaking toxic fumes in the path of the cab and it gives me a headache I’ve done research and this is a common issue
The truck has developed a significant knock coming from the intake manifold. It is loud enough to hear with the hood closed. The problem exists warm and cold. The knock was verified by Sunrise Ford in Fontana, CA in December of 2024. The Dealership had another F250 on the lot with the same 6.2 engine and that it also has a knock coming from the intake manifold, so they considered the situation "normal". There is a significant amount of information available that the knock is related to an impending failure of the Intake Manifold Runner Control (IMRC). If the IRMC fails, the parts will go into the combustion area and could cause an immediate catastrophic failure of the engine. At best this problem creates a loss of power and a pulsing vibration at idle.
(UNKNOWEN) I have a problem with accelerator pedal lag time, when pushing down on the accelerator pedal nothing happens at first then you get acceleration which isn't good it's like the truck falls on its face then jumps forward. This is a real problem when driving in traffic or really any time. I have spoken with Ford about this problem but all I get is that's the way it is, Ford needs to fix this problem it's a safety issues, I have looked on-line and I'm not the only one with this problem. This lag problem happens at any and all speeds.
