2020 Ford F-150 engine problems

Filed Oct 19, 2026 · Acceleration, Engine · NC

The Transmission has failed. Hard shifting, random gear switching while driving at any speed. i put it in reverse and it went forward while in reverse. it slows itself down while on the highway. it acts like it wants to turn off while running, its a matter of time before I'm driving down the road and it decides to stop suddenly and cause an accident. I got it diagnosed by truck works garage and they confirmed that the shifting was all over the place with random high rpms. The dealership quoted me $2500 just to diagnose the problem so i had it diagnosed at truck works garage for $160 to confirm the issues matched the tsb's and recalls that they wont acknowledge my VIN for. The failure 1st appeared 5 years ago when i was under warranty, i took it in (and have the work order still dated 10/22/202) for hard shifting and they brushed me off and sent me away with false information about the cause. 5 years ago (25 days before i brought it in for the hard shifting) there was a tsb 21-2315 published for the exact issue on my truck, They ignored it and sent me away without fixing anything or addressing the issues.

Brought my 2020 Ford F150 2.7L EcoBoost in for mandatory emissions recall 24E12. Vehicle had zero dashboard lights or performance issues prior. Immediately upon completion of the PCM flash, the check engine light activated. When the truck was scanned I am now receiving a P0420 and P0430 catalytic converter efficiency codes. The dealership is now requiring $6000 for replacement of qty 2 catalytic converters caused by the recall parameters. This is a predatory compliance software update designed to shift manufacturing component failures onto the consumer after the 80k mile warranty window (truck has 105k). I have filed a complaint with Ford and asked for a P01 Financial Review for After-Warranty Assistance and have been told there is nothing Ford can or will do to assist and I must pay them $6000 if i want them to fix this. Because of this the vehicle is now not emissions compliant.

My 2020 Ford F-150 (5.0L V8) experienced a sudden loss of engine power and stalled completely while I was driving. In the days leading up to this, the check engine light had illuminated, and I later discovered the vehicle had consumed a severe amount of engine oil — the dipstick read below the "add" line. Critically, no low oil pressure warning light or audible chime alerted me to the oil loss before the stall occurred. After the initial stall, the engine continued to struggle to maintain idle and stalled repeatedly whenever RPM dropped to approximately 1,000, making the vehicle unsafe to drive. I had the vehicle towed to a Ford dealership for diagnosis. The dealership's estimate confirmed the need for a full engine (long block) replacement, at a cost of approximately $19,824.56 (total estimate $21,491.04). I am aware that Ford issued Technical Service Bulletin 19-2365, which acknowledges that 2018-2020 F-150 trucks with the 5.0L engine may experience excessive oil consumption exceeding one quart per 3,000 miles with no visible external leaks, attributed to oil being drawn into the engine during deceleration fuel shut-off events. I believe this defect directly caused my vehicle's stalling and oil starvation, and that the lack of any dashboard warning prior to the failure is a separate and significant safety concern, since a driver has no way to know the engine is being damaged or that a stall is imminent.

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.

Camshaft had to be replaced a couple years ago, followed by cam shaft sensor. Then another $6,300 of "critical" issu3s to be fixed. The vehicle is 5 1/2 y/o. Absolutely ridiculous that this amount of money is required for such a young vehicle.

Back in Jan 2025 I noticed oil consumption from 2020 F150 with the 5.0 engine. There is class action lawsuit against Ford currently for this problem they know they have. I informed my local dealer, that has always serviced my tuck on time over the years, that it was smoking. I have owned this truck since new in Sep 2020. It had roughly 33K miles on it when I first noticed it. The dealership started running consumption test on it under warranty at 36,370 miles. They changed the oil regular for the test and instructed me to drive it 1000 miles each time between changes. One change before they tried to fix it, it had consumed 5 quarts of oil. Ford says 1 quart per 10K miles is normal. They changed several motor parts when it was at 41,121 which took about a month. The problem got worse and I informed them and they again started testing it again and instructed me to drive it 1000 miles each time. They pushed the milage up and also ran it over on the warranty time frame and it has been at their location for over a month now, and Ford doesn't want to pay for a motor that only has 48,086 miles on it due to being out of warranty. They knew this problem existed and caused the warranty to laps and never fixed it. Now they are asking me to pay $11,598.42 for a new motor they knew was bad 15k miles before warranty went out. I am going through steps to make someone aware of this issue I'm currently dealing with. This motor has this problem, and they knew it and never fixed it and intentionally ran my warranty out so they would not have to cover it.
