Ford F-250 SD engine failure problems

Filed Nov 4, 2026 · Engine · AZ

I have a 2021 Ford F250, the truck was bought new has 34,467 miles on .Oil changes every 5000 miles. Was returning home from camping and engine developed a miss, engine light came on,I was able to make it home and engine developed a loud ticking noise in the upper part of the engine. Truck was towed to a Ford dealer ,where it sits for the past 2 weeks ,waiting on Ford to decide what they are going to do with it. Dealer told me ,after a tear down ,that Ford wanted ,that it was the cam and lifters. This is a known problem ,and Ford dropped the ball on a recall on this engine. Besides the cam ,lifter issue ,there is an oil pump problem with this year engine. I bought the truck as a retirement gift to myself, and now appears to be the worse decision I've made. I believe Ford needs to replace the engine and not just fix the cam and lifters as small metal particles will be through out the engine due to the above failures and will cause a failure again.

I am filing this complaint regarding a catastrophic engine failure in my 2020 Ford F-250. The engine experienced low oil pressure due to a failure involving the camshaft (cam). The failure resulted in damage severe enough that the entire engine had to be replaced. Component or System Failure: The component that failed was the camshaft within the engine. The failure resulted in low oil pressure and subsequent internal engine damage, ultimately requiring complete engine replacement. The failed engine and/or components may be available for inspection upon request, subject to confirmation of their current location and availability. Safety Risk: This failure created a significant safety concern. A sudden loss of engine oil pressure can result in catastrophic engine failure, loss of engine power, and potentially an unexpected vehicle shutdown while driving. Losing engine power while traveling at highway speeds or in traffic could put the driver, passengers, and other motorists at serious risk of an accident. The possibility of sudden engine failure without adequate warning is particularly concerning in a heavy-duty pickup truck that may be used for towing or hauling. Dealer or Independent Service Confirmation: The engine failure was serious enough that the entire engine required replacement. The low oil pressure and resulting engine damage were identified as the cause of the failure. The repair and diagnosis were handled through a ford dealer. Specific diagnostic findings and documentation can be provided if requested. Inspection by Manufacturer or Other Parties: The vehicle was serviced due to the engine failure and underwent evaluation as part of the repair process. Whether the failed components were independently inspected by Ford Motor Company or other parties is UNKNOWN. Warning Lamps, Messages, or Symptoms Prior to Failure: The primary symptom associated with the failure was low oil pressure. No lights were on at the time of service.

My vehicle has been at Ford of Harvey since 8/31/26. Dealer replaced ignition coil 8/18/26. Light and rough idle returned and the dealer determined a new engine would be needed. Dealer says Ford warranty only wants to replace cam shaft. Metal in oil was found and dealer has fought corporate warranty for over a month, ripping apart my engine. The fear is engine could seize at highway speeds as a result of internal damage.caused by circulating debris. Truck still sits at dealer.

- Oil leak at 300 miles. - Oil loss can lead to catastrophic engine failure and loss of drivability. - Oil leak can be easily repeated after wiping down and driving as little as 6 miles. - Dealer changed the oil drain plug but that didn't correct the leak. Self inspection indicates the leak is coming from around the oil cooler, which the dealer was informed of. - Symptoms were noted by leakage on garage floor.

10 day roundtrip from [XXX] to [XXX]. 5 incidents of catastrophic engine failure on interstates. Truck started to jerk, sputter, lost power at an alarming rate. No engine light until failure ocurred. Very dangerous with heavy holiday traffic. Lives were in danger, us and other vehicles around us. No one expects travel to go from 70 mph,to 50, 30, 15 in such a short period of time. Pulled over to "investigate" code failures we deemed as o2 sensors. Afterwards the truck started back up, no engine lights and drove as normal. Started using premium gasoline, hoping it would help. Started driving in right lane as much as possible but had a failure ocurr right in front of on ramp as well at interstate speeds. Had another family following us so they also witnessed and pulled over all incidents. Brought into Ford 7/18/24 upon return home. Paid $125 inspection fee, concern not present, come back if happens again. Makes no sense that codes not present to pull. 12/13/2024 engine light on, catalytic converter replaced. 06/19/25 truck had catastrophic failure returning from work on hwy. XXX on [XXX], just two miles from leaving home another failure with no warning lights in heavy Friday traffic in construction zone. Couldn't clear the traffic lane completely. Very scary. Waited for clearing and limped it to a nearby off ramp. Same jerking, loss of power. Vehicle towed to shop for 2 weeks, testing, fuel pump replaced. Picked up 07/07/25. Next day received recall notice 25S75 in the mail 7/08/25. Everything made sense. 1/24/26 - Battery failed inspection @ 40% during oil change. Replaced battery ourselves from Costco. 04/23/26- Warning light, P0420 pulled, shop recommended engine tune -up. Paid $175 inspection fee + $671.20 tune up. 5/29/26 engine light on, P0420 pulled, recommend catalytic convertor replaced but not under factory warranty anymore so wants us to pay $4000 bill. Escalated up through Ford. As of 6/5/26 - Ford will pay half. I refuse. Should be covered by recall. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF I
