2018 Ford F-150 problems

“The transmission has been replaced once covered under Fords extended warranty at 90,700 miles by the previous owner in 2022. Today the transmission has 82,000 miles on it and requires to be replace again. This 10r80 Transmission has a known issue of in early models from 2017-2020. I was stopped at a stopped at a 3-way stop, and began to pull out into the intersection to make a right. Half way through the turn the truck would not go into 2nd gear and felt like as if it was in neutral and I lost power for about 6-8 seconds. During this period, another truck coming from the left, stopped at a stop sign as well, honked impatiently and then decided to go, driving in front of me. Just then my truck slipped into gear and lurched forward almost colliding with the other truck. On top of that there was a bystander waiting to cross the street, on the other side of the crossing truck, who would have sustained serious injuries if I could have not been able to stop by truck in time. Later when it would not slip into gear a wrench light came on and the transmission was stuck in 6th gear even at a stop. This light only went away once the tuck was turned off then on and the…”

“3 separate things recently happened. First the cam phasers went out, $4600. Second, only months later, the transmission went out, $7100. Third, it is throwing a p0420 and p0421 codes and the catalytic converts need replaced, at least $2000. All of this under 100k miles.”

“I am getting heavy water intrusion from the rear sliding glass window after any rain. It creates a very musty unpleasant odor in the cab. I am concerned that my young children, my wife, and myself are breathing mold spores and or other dangerous airborne particles from this problem.”

“About 1 year ago the rear door on the drivers side locked and I have been unable to open it manually, with the interior unlock buttons or with the key fob. However, there have been 3 occasions during this passed year when the door inexplicably opens, twice when the truck is parked and once when I was driving down the freeway. To be clear, the door doesn’t just unlock, it opens. On those 3 three occasions, when I closed the door, it again locks and I’m unable to open it. I’ve taken the problem to 2 Ford dealerships. Both indicated they had never heard of this problem and there were no recalls related to the problem. One dealership diagnosed the issue, charging $100 and determined it was the door latch and offered to replace it ($472 for the latch and labor to be determined). I opted not to repair it thinking that the problem should be further diagnosed to determine if there are flaws in factory parts that create safety issues in this particular truck, make and model.”

“The contact owns a 2018 Ford F-150. The contact stated that while driving 55 MPH on the highway, the vehicle lost motive power, and the brakes became inoperable. The drivetrain and wrench symbol were displayed. The ABS warning light was illuminated and DTC: U100 (Failure of Communication for Engine and Transmission) was displayed. The codes were cleared after restarting the vehicle. The vehicle was taken to the local dealer, where it was diagnosed with a communication error with the engine and transmission computer. The vehicle was repaired, but the failure reoccurred. The transmission upshifted from first gear to seventh. After a while, the vehicle resumed normal operations, but then the vehicle drove abnormally. The RPM increased to high, and the temperature gauge was at HOT. The vehicle was taken back to the dealer and was diagnosed with complete transmission failure. The vehicle had not been repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 62,513.”

“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…”
