2021 Ford F-150: engine failure

Filed Oct 29, 2026 · Engine · MI

I had an oil change performed earlier in the day. Drove 90 miles on the oil change when I lost complete oil pressure and than had my engine lock up. After the truck was towed back to the dealership and some surface investigation was done they told me it would be 2K to take the oil pan off to get a definitive answer to the issue. For them the only fix was replacing the entire engine at 14k. They believed it was just bad luck timing the occurrence of the loss of oil pressure and engine failure. The event happened with 135,556 miles on the vehicle. At 122,000 miles I had my drive shaft detach on the expressway. At the time I was still under extended warranty on the truck. The fix for that was a new drive shaft and to replace the rear axle. The issue I have is believing that 2 catastrophic events on the vehicle would occur within 12k miles and the three events not being connected. The manufacture wasn’t able to provide me with any answers as to what failed or why making it incredibly difficult to make a huge financial decision on what to do. I struggle with a vehicle that has that low of mileage would just completely implode and be undrivesble.

My engine failed. They recalled this engine but mine wasn't recalled. My engine did the same thing as the recalled engine did. Excessive oil consumption. When I first took it to Ford dealership it was under 60K. I have had problems with my truck since Easter have taken it to them a few times. The problem was never fixed and now Ford will only cover 4,950. The engine is 12k. I feel since the engine in my truck was a recall on alot of engines. Mine should be covered under recall or warranty up to 60,000 miles. I have nothing but problems since I bought the truck. I started taking the truck to have it looked at since March to other places they couldn't help me so they told me to take it to the dealership. They keep fixing something on the truck but never the part that was broken. They told me it would be ok to drive it and so now I am over the mileage for my warranty. I don't think I should have to pay to replace my engine when it only has 61K miles on it. so they told me to drive it and then it started knocking and the engine failed. The service manger told me it was a failed bearing. certanily no lack of maintenance so why am I stuck paying for this when it wasn't my fault. they found some damge on one of the rod bearings on the bottom. 2021 Ford F-150 V8 that engine had a recall on it. Not sure why mine wasn't recalled. Can you please help me. My truck is at Larry H Miller Ford in Draper Utah. It has been there for 5 weeks this time. Still no engine in it.

Vehicle is consuming excessive amounts of motor oil, requiring the addition of 1-2 quarts every 1,200-1,500 miles. Check engine light has illuminated once when engine was five quarts low, this was when I realized the problem. Ford has attempted to correct with TECHNICAL SERVICE BULLETIN 19-2365, (5.0L - Excessive Oil Consumption) which I had performed on my vehicle and it did nothing to correct the issue. My greatest concerns are with premature parts failure and unexpected engine failure. I have written letters to Ford regarding this issue and have not received any response to date. I do have records of additional oil added since first realizing the issue existed.

My truck has a 2.7 eco boost engine than has failed around 134,000 miles. The truck had a couple of misfires over the last couple of months, but otherwise no issues. I drove the truck one Saturday, did not drive Sunday, and on Monday I am told the engine is completely seized and I am responsible for replacing the engine. Ford will not attempt to determine if the recall for the valve intake stem has caused the issue and now I am spending over $12,000 to replace a 4 year old engine with no other issues.
