2020 Ford F-150: engine failure

Filed Sep 9, 2026 · Transmission · AL

Transmission slips gears and sometimes shifts violently. I took the truck to a Ford dealership for an assessment and was told I need to replace the whole transmission. I also have a problem with oil consumption from the engine. I was told by the same dealership that this was a known problem with the 5.0 engines built from 2019 to, I believe 2023 and that it would require an engine replacement. I bought this truck from an individual and now I am stuck with it.

We purchased a used 2020 F­150 in late summer 2024. We brought it in for issues in November 2024, but the Ford dealership found no repairs were needed. We returned in March 2025 when the CDF drum failed requiring a transmission rebuild, a known issue with Technical Service Bulletin but not a recall. The engine continued consuming oil after this despite Ford completing all applicable service bulletins and advising there was nothing further to do. We took the vehicle in for service in May, 2026 and were told they had already updated software to address the oil consumption and we were told that should resolve the issue. On June 30, 2026, the truck was towed to the dealership after repeated stalling and a check engine light. The dealership again acknowledged this is a known issue with this engine - the valve seals are defective yet they had stalled our concerns so long at this point, we were past the warranty period. We researched and found this was a widespread, known issue asked whether Ford would offer customer loyalty assistance after 30 years of Ford ownership. We were told the truck's approximately 118,000 miles exceeded the assistance threshold. The engine replacement was quoted at $15,000. Ford advised us to repair the engine and save our receipt in case they should issue a recall at some point in the future. Given the value of the truck was $15,000 we chose not to keep investing in this vehicle and sold it for parts at a loss.

I own a 2020 Ford F-150 with the 5.0L V8 engine and have under 60,000 miles on the vehicle. The engine is consuming excessive amounts of oil — approximately 3 to 4 quarts every 5,000 to 6,000 miles under normal driving conditions with no visible leaks or blue smoke. I brought the vehicle to a Ford dealership and opened a formal case with Ford Motor Company. Ford performed an oil consumption test and stated the consumption was within acceptable limits. I do not find this acceptable for a relatively new engine and the owner’s manual does not indicate that adding oil between changes is normal or expected. This level of oil consumption poses a potential safety risk as inadequate lubrication can lead to premature engine wear and failure. I am requesting that Ford acknowledge this as a defect and provide a remedy under the powertrain warranty. Other F-150 owners have reported the same issue and I believe this warrants a formal investigation

My 2020 Ford F-150 5.0L Coyote V8 had its engine replaced under factory warranty on 4/30/25 by an authorized Ford dealer. The replacement engine was installed with my original 50,000 mile fuel injectors reinstalled by Ford's technician — I was not informed new injectors were not included. The vehicle is now diagnosed with a failed direct fuel injector causing a cylinder 3 misfire at approximately 10,000-12,000 miles on the replacement engine. Additional injectors show signs of imminent failure. The shop also documented the replacement engine running 2 quarts low on oil at only 10,000-12,000 miles of service. This level of oil consumption on a recently replaced engine is abnormal and unexplained. The safety concern is twofold. First, a vehicle running chronically low on oil due to abnormal consumption on a replacement engine risks catastrophic engine failure without adequate warning to the driver. Second, misfiring cylinders affect vehicle driveability and create unpredictable power delivery that constitutes a safety risk particularly at highway speeds. Symptoms including rough running and the check engine light first appeared in November 2025. The vehicle has been at an authorized Ford dealer for diagnosis since May 2026. Ford Customer Relations has declined goodwill assistance despite the failure occurring on components reinstalled by Ford's own technician during a warranty repair, symptoms originating within the warranty window, and the vehicle being only 8 days outside the 12-month parts warranty expiration. I am requesting the federal safety agency investigate whether Ford's practice of reusing high-mileage fuel injectors during engine replacements under warranty constitutes an unsafe practice, and whether abnormal oil consumption on replacement engines represents a systemic defect.

I purchased a 2020 Ford F-150 XLT with a 5.0L engine from Quirk Auto Group in Maine approximately six months prior to discovering a major engine defect. At the time of sale, I was provided documentation stating there were no known mechanical issues or prior defects with the vehicle. Shortly after purchase, I brought the vehicle back to the dealership due to a noticeable rattling noise and performance concerns. I was told the noise was caused by debris (rocks) stuck in the undercarriage, and no further action was taken. This concern was documented during that visit. Over time, the vehicle began consuming excessive amounts of oil, approximately three quarts per month which is far beyond normal operating conditions. I later brought the vehicle to a certified Ford dealership for further diagnosis. After inspection, I was informed that the engine had significant internal wear, including worn cylinder walls, and required a full engine replacement (long block), with an estimated cost of approximately $15,785. I have since learned that this engine issue is consistent with a known defect documented in Ford Technical Service Bulletins (TSBs) as well as an open class actions lawsuit against ford, and records indicate this issue had been present with the previous owner. This information was not disclosed to me at the time of sale. I have made multiple attempts to resolve this issue directly with both the selling dealership and Ford Motor Company. Ford has offered partial financial assistance toward the repair, which further indicates acknowledgment of a defect. However, the dealership has not taken responsibility for selling a vehicle with a pre-existing condition that was either known or should have been known.

The engine started running loud and making a knocking noise. Took it to the dealership and they said it needs a new engine. Regular maintenance performed by Ford. There were no warning lights that came on prior to the engine failure. They say the engine is on back order.

Ford is aware of the engine failure on the 2020 Ford F-150 5 liter Coyote V8 models. These vehicles consume excessive amounts of oil which leaks and causes engine failure. We took the car to Ford several years ago complaining about the issue and spent a good bit of money to 'fix' the problem. However, it is not fixed. We had some repairs done last week at our mechanic and they said the engine needs to be replaced. If not, it could lock up and cause major damage to the car. This car is 5 years old and should not be having engine replacement problems. Ford was replacing the engines when the issue was first discovered but then began telling people to keep putting oil in the vehicle which is not solving the problem and actually causing more problems and damage. This is the 4th Ford F-150 my husband has owned and not had any problems. His last Ford went for 300,000 miles before we sold it (it was still running great). Can provide all maintenance records as needed.

While driving at normal speed, the vehicle suddenly began producing heavy white smoke from the exhaust, the engine started to idle roughly, and a check-engine light came on. There was no oil-pressure warning, no low-oil message, and no “stop safely” alert of any kind. The only warning was emissions-related. After seeing the smoke, the vehicle was parked and later driven only to a dealer for inspection. A dealer inspected the vehicle and confirmed that an internal seal in one of the turbochargers failed, causing the engine to pump all of its oil directly into the exhaust system. This resulted in complete oil loss and catastrophic engine damage due to oil starvation. The dealer confirmed the failure and determined that the issue originated from the turbocharger assembly and not from misuse or neglect. The failure occurred suddenly and without any oil-pressure warning to alert the driver. The safety concern is that a turbocharger failure caused total loss of engine oil without triggering any oil-pressure warning or driver alert, creating a risk of sudden engine failure, loss of power, or engine seizure while driving. The lack of oil-pressure warning before or during the event was confirmed by the dealer’s inspection.

At roughly 9:55pm on Thursday, July 11th while traveling northbound at 70mph on the Dallas North Tollway, my 2020 Ford F-150 Shelby Baja Raptor had an instant catastrophic engine failure. All power to the truck was lost. A red solid battery light came on the a yellow engine light began flashing. I was EXTREMELY fortunate, in that I was able to guide and control the vehicle off of the freeway, on to the service road and glided into a hospital parking lot. The steering completely locked up while navigating from the service road into the hospital parking lot. Once again I was EXTREMELY lucky. This was a terrifying experience that is imporrible to describe with words. The next morning I had the truck towed to a reputable auto repair business close by. Later that day the owner of the business informed me that the crankshaft sheared into where it meets its connection to the engine. He cited that this is EXTREMELY rare and would visit with Shelby America on Monday morning(today 7-14-25). There were no warning lights of any kind that have come up within the last year. The vehicle was purchased locally in the Dallas/Fort Worth area. All maintenance...scheduled and non-scheduled have been performed at the same Ford dealership where the truck was purchased. The truck has had $40,000 worth of maintenance on it since the beginning of 2025. This failure doesnot make sense. The Auto Repair shop indicated that I need a new engine. They also didn't understand why this would happen.
