2020 Ford F-150

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.

I. Vehicle Purchase and Maintenance History In September 2020, I purchased this 2020 Ford F-150 new. II. Chronology of Defect and Repair Attempts Around 33,000 miles, the vehicle began exhibiting severe excessive oil consumption, an audible engine noise, and visible blue/gray smoke puffs emitting from the exhaust system. The following timeline outlines my exhaustive efforts to have Ford remedy this under warranty: • March 14, 2025 (36,370 miles): First formally reported the noise and exhaust smoke to Service Advisor Shelby Ray. The dealership initiated an official Ford Oil Consumption Test. I was instructed to drive 1,000-mile increments and return for unrecorded level checks. • May 21, 2025 (38,200 miles): Second formal report. The dealership performed Technical Service Bulletin (TSB) 192365 CP:6006, an established protocol recognizing inherent oil consumption flaws in this specific 5.0L engine. • August 7, 2025 – September 11, 2025 (41,119 miles): Third formal report. The vehicle was left at Tony Serra Ford for over a month (RO # 6034434) to perform engine repairs mandated by Ford tech lines. A loaner vehicle was provided. • December 9, 2025 (44,144 miles): Fourth formal report. The defect was noted as unresolved and still present between oil changes. The engine was found to be 2 quarts low on oil upon arrival. A new tech line case was opened. • May 7, 2026 – Present (48,086 miles): Fifth formal report. The engine noise and exhaust smoke. Truck has been at dealer for 3 months with no resolution.

The contact owns a 2020 Ford F-150. The contact stated that while attempting to start the vehicle, there was an abnormally loud sound coming from the vehicle. Additionally, while driving at an undisclosed speed, the vehicle was idling abnormally rough. No warning lights were illuminated. The vehicle was taken to the dealer several times, however the failure was not duplicated. The contact stated that the failure was a known failure with the vehicle. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 28,000.

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.

Engine shut off at 60mph on mountain road. No warning, noise or other indications. Warning appeared once engine shut down; instructed to stop and restart vehicle. All temps and pressures were in normal operating range at time of shut down. wrestled vehicle to a stop, towed home (midnight) and then towed to dealership next morning. Safety at risk with vehicle shutdown at 60mph, fortunately no traffic and shoulder was available. Motor is available at the dealership, has been inspected and diagnosed as complete engine failure, engine seized with no know/visible cause without extensive teardown.

Driving on freeway 10 speed transmission failed - hard knock and jerk, almost got in an accident. Gears 6-9 dead. Apparently this 10-speed transmission is a known issue, with many technical service bulletins issued, class action lawsuits, and angry customers. Ford refuses to issue a recall and the NHTSA refused to hold them to account. Something is broken - how can Ford make such a known, terrible important component to a vehicle that fails regularly - yet get away with it? I thought the NHTSA was supposed to protect us from these unsafe vehicles?

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

I was driving and slowing down for a stop sign and the engine shut off by itself while still moving at appx 10-15mph. The display had several warning lights appear, and the message "Auto Start Stop, Shift to P, Then Restart Engine". I have the Auto Start Stop disabled on my vehicle, so there was no reason for my engine to shut off while decelerating. I searched online for potential causes and discovered that there are numerous incidents of this happening (engine shutting off while moving) to drivers that have deactivated the auto start stop on their vehicles.
