The contact stated while driving at an undisclosed speed, he had a loss of motive power and check engine warning light was illuminated when driving, almost causing an accident due to not being able to accelerate. The vehicle was taken to a dealer where it was diagnosed to have metal shavings in the combustion system. The contact received notification of NHTSA Campaign Number: 24V957000 (FUEL SYSTEM, DIESEL); however, the SSSC (Special Service Center assistance request) was declined by Ford agency (SSSC), due to the issue not having metal shavings although the dealer technician stated there were shavings.

The component/system that failed or malfunctioned is the SCR (Selective Catalytic Reduction) NOx Catalyst Efficiency system, triggering DTC P20EE – SCR NOx Catalyst Efficiency Below Threshold (Bank 1). This issue began immediately after Ford Recall 24S78 (PCM software update) was performed on April 29, 2026 at Ferman Ford of Countryside. The truck had zero emissions or check-engine issues prior to the recall flash and was perfectly maintained to Ford standards with Howes diesel treatment every tank. The problem has been reproduced and confirmed multiple times by the dealer: After the May 4 PCM reprogram per TSB 21-2248 After replacement of both NOx sensors on May 5 (code returned in under 17 miles) After replacement of the DEF injector (code returned again) The dealer only performed one manual DPF regeneration instead of the two required by Ford SSM 49202 and pinpoint test RD15, and they did not complete the SCR Parameter Reset. They are now quoting an additional ~$2,000 out-of-pocket for a DPF replacement after partial goodwill assistance was approved. The vehicle has been repeatedly inspected and repaired by Ferman Ford. No independent inspection yet. Ford Customer Service has been contacted and partial goodwill was approved, but significant out-of-pocket costs remain. Warning lamps/messages (Service Engine Soon light + “exhaust emission control system is not operating as expected”) first appeared immediately after the April 29 recall PCM flash and have continued ever since. Safety risk: A loss of motive power, entry into limp mode, or reduced power while driving could result in a crash or inability to maintain highway speed. This appears to be a direct consequence of the Recall 24S78 PCM software update tightening emissions monitoring. All repair orders, photos of warnings, and supporting documents are attached for your review. There is 12. I was not able to upload the last of the documents.

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 have sent in a previous complaint as our truck would die in the middle of the road, due to the fuel pump. It is unacceptable that Ford has not resolved the recall issue in 9 months. Our truck is needed daily for our business. Please make Ford take action.

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.
