2018 Ford F-150 Complaint Log

The contact owns a 2018 Ford F-150. The contact while parked and attempting to start the vehicle, there was an abnormal knocking sound coming from the engine. There was no warning light illuminated. A dealer was contacted. The vehicle was taken to a dealer to be diagnosed. The contact was informed that the valves inside the engine needed to be replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 68,000.

Splash guard under the vehicle, sometimes also referred to as a diaper, fell off. I reported it to the dealer and was told I didn't need it anyhow. Well, if I didn't need it anyhow why did they put it on to begin with ? I also notice a lot of other Ford vehicles driving down the road with these guards (diapers) hanging down, so it isn't just a me problem it's a Ford problem. After inspecting the guard it is made of such cheap material I don't know how any engineering designer could of thought that these would hold up given the environment under a vehicle especially a truck. I would also think that this could easily become a road hazard.

Coil spring on the front drivers side suspension snapped in half while driving causing a momentary loss of control that was quickly regained. The spring was replaced at a local repair shop. There were no warning signs before failure occurred.

Transmission: sluggish upshift (vehicle feels like it is being pulled backwards), hard shifting and sudden downshifts at speeds in excess of 35 mph. Narrowly avoided getting rear-ended during rush hour traffic. I have not taken the vehicle to the dealership due to being afraid to drive it. No warning lamps, but symptoms started about two weeks ago but were very intermittent and easily resolved with a TCM relearn. Symptoms are similar to the known issues with the Ford 10R80 CDF Drum issues. I will be having the vehicle towed to the service center next week for a diagnosis and way forward. On 18 June 2025, I was traveling home from work. I stopped at a red light and waited for the light to turn green. The light turns green and the line of cars (roughly 20, with the lead car approximately 5 ahead of me) begin to proceed through the light. As I passed through the intersection and began to pick up speed, my vehicle shifted into 6th gear at about 40 mph. Less than 2 seconds after shifting into 6th, it shifted down to 1st gear, lost all power to the drivetrain, and almost caused a collision between me and the car behind me in a busy residential area. Pressing the accelerator only revved the engine. I turned my hazards on and shifted the vehicle to Manual and was able to get it going again but the same symptoms happened at my next stop and have persisted since.

Transmission is hard shifting and dropping out of gear into neutral at random times. Ford dealership diagnosed a bad CDF hub in transmission. Ford knows this is a known issue and redesigned the part but not covering any repairs.

Component/System That Failed: The 10R80 automatic transmission in my 2018 Ford F-150 3.5L EcoBoost has become essentially undrivable at 89,900 miles. The transmission will attempt to upshift from 1st gear through each gear unsuccessfully until it reaches 6th gear, at which point it refuses to downshift. The only way to exit 6th gear is by taking the vehicle completely out of drive. This transmission is available for inspection upon request. Safety Risk: This failure creates a major safety hazard. The inability to accelerate properly from a stop or to downshift while slowing down means the truck cannot respond to normal traffic conditions or emergency situations. This puts me, my passengers, and others at risk—especially when entering traffic, making turns, or attempting to stop. The erratic behavior also causes the vehicle to lurch or hesitate, increasing the chance of a rear-end collision or loss of control. Has the Problem Been Reproduced or Confirmed? Yes, the issue has been confirmed by a certified Ford dealership. They diagnosed internal transmission failure and quoted $8,876.27 for a full transmission replacement. Has the Vehicle or Component Been Inspected by Others? The vehicle has been inspected by a Ford dealership service department. No inspections have been done by law enforcement or insurance, and the manufacturer has not taken direct action, despite this being a well-documented issue with multiple TSBs and class action lawsuits tied to the 10R80 transmission. Warning Signs or Symptoms: The issue began gradually around 75,000 miles with hard or delayed shifting and worsened significantly by 89,900 miles. there was no warning light or messages until after the transmission gave out in the middle of a busy intersection. The truck now frequently: Fails to shift gears properly Hesitates or jerks unpredictably Becomes stuck in 6th gear This ongoing and worsening problem has made the truck unreliable and unsafe for everyday use.

Just got off the Interstate on to a frontage road when I received a low brake fluid light warning. Instantly lost braking power. Was traveling approximately 40mph downhill toward a traffic light where cross traffic was going full speed. I had to activate my emergency brake to stop from running into the cross traffic. Got the truck into a gas station, checked the brake fluid reservoir & it was below the minimum fill line. Purchased brake fluid at the gas station, filled it up & drove and the parking lot. The brakes partially worked, but the reservoir drained quickly again. I was lucky that there was a brake service repair shop within a quarter of a mile, so I refilled the brake fluid to the max & drove slowly with hazards on to the shop & left it there. Today they told me it was a brake master cylinder internal failure that caused brake fluid to leak into brake booster resulting in loss of braking power. While my truck is not covered under an existing recall, there is a recall for this exact issue for the same make & model of my vehicle (but with a different motor). That is NHTSA recall # 25V-236. I believe this recall should apply to my truck.

NHTSA Safety Complaint Draft Vehicle Information: Make: Ford Model: F-150 Year: 2018 VIN: [XXX] Incident Summary: While driving my 2018 Ford F-150, the vehicle suddenly displayed a warning on the dashboard: “Steering Assist Fault – Service Required.” Within moments of this warning, I lost all power steering assist and was unable to control the vehicle, resulting in the truck veering off the road and into a ditch. This was a sudden and dangerous failure of the Electric Power Steering (EPS) system. I was fortunate not to have been injured, and no other vehicles were involved. However, this type of failure represents a major safety risk to me and to others on the road. I contacted Ford Motor Company and was assigned Case Number: [XXX]. Despite reporting the issue and explaining that the vehicle ran off the road, Ford refused to offer any assistance or goodwill repair. I was told the vehicle is outside of recall 24S45, even though it displays the exact same failure symptoms as recalled vehicles from later years. This failure could have resulted in serious injury or death. I am requesting that NHTSA investigate this steering system failure and expand any related recall coverage to include affected 2018 F-150 models like mine.

Hard shifting slamming gears needing transmission work.

Plastic two piece oil pan installed by factory with insufficient RTV resulting in a significant oil leak and possible fire potential as run back of oil reaches exhaust components. Vehicle is well kept and serviced regularly with less than 100k miles. Vehicle is out of warranty and down time is several days for a fix that results in using the same plastic oil pan with an estimate of $1200. Unfortunately this same oil pan will result in a similar leak in the future if fixed. Aftermarket aluminum options are available which result in a much better sealing surface.

The vehicle was riding rough and then it cut off.

Transmission shifts erratically causing loss of power at highway speeds. Transmission issues have occurred since the first month of ownership. Truck lunging when in park, down shifting from 10th gear to 7th at highway speeds, etc. Early problems/concerns were mentioned to service advisors when the truck would be taken in for service but I was always told, that is just the way that the 10R80 works. As time progressed, shifting issues got worse. They significantly increased after the powertrain warranty expired. Currently the truck shifts erratically in low and high gears and frequently experiences a complete loss of power travelling on the interstate. My biggest concern is that this is a known issue by the Ford Motor Company that has not been properly addressed via recall. The CDF drum inside of the transmission has a known design flaw and has been revised to eliminate the issue. The web forums dedicated to the F150 and any other model of vehicle ford equipped with the 10R80 are littered with similar stories and concerns regarding the transmission. ultimately, with the total loss of power at highway speeds and the need to immediately vacate lanes of travel to allow the vehicle enough time to figure out what gear it needs to be in, or to shift appropriately to regain highway speeds poses an immediate threat to any vehicle equipped with the 10R80 transmission and the original, or any early design, CDF drum. I would also like to note that I entered this with the most recent occurrance of this issue. It has happened multiple times during the course of ownership both before and after the warranty expired. Unfortunately, all of the Ford service writers/techs/managers, claimed that it was normal operation of the transmission.
