The 2018 F150 I purchased started out a good vehicle like most vehicle do. The problems then began to come one after the other. Routine oil changes on the vehicle at the dealership with no hiccups turned into “Your motor is low on oil”. The tech tried to find a leak. The motor wasn’t leaking ANYTHING, so naturally the tech told me the motor was burning the missing oil. The tech told me “they all burn alittle oil” and topped it back off. I had another “incident” where I was driving on the highway a few weeks later and my engine light came on, and I lost oil pressure. The red “low oil pressure” message came on the dash and I promptly limped my truck to the dealership once again. The tech diagnosed the truck and found a plugged PCV valve. It was changed for a brand new one from the dealer, followed by another oil change well under the recommended interval naturally, due to the motor burning almost all of the oil. The truck still burns oil, and the issue seems to be impossible to remedy. The issue that followed the engine burning oil is the 10R80 Transmission installed from the ford manufacturer. Once again everything seemed fine when I purchased the truck. After driving it for 20-30k miles, the transmission has developed a flare shift between the 3rd-4th gears. The transmission is getting more and more hesitant to upshift and maintain and gain speed. This is considerably noticeable when attempting to get on the highway. This is unacceptable. It puts me in a very vulnerable spot because it doesn’t happen all the time. So I have to be EXTREMELY aware and prepared for the truck to become inoperable while merging into the flow of traffic. On two occasions now, while merging onto the highway with traffic, I have had to pull over to the shoulder of the road and put my hazards on to allow traffic to go around me due to my 2018 F150 with the 5.0/10R80 combination NOT increasing speed, and reving close to 5k RPMs. THESE ISSUES MUST BE ADDRESSED.

The transmission failed at 116000 miles. Initially it was due to low oil level, never checked at the dealership in all the services I've had done. I added a quart to bring up to the property level. Had the fluid and filter changed the next day, and techs didn't say anything about what they found during the test drive they did. Ford then went straight to me needing a new transmission at $11000 for parts and labor. An independent technician that is Ford certified also looked at the vehicle and transmission and confirmed it's most likely the CDF clutch cylinder and the "Trashcan" as it's called. These are both known issues and it's why Ford updated the design after several failures at low miles. The independent mechanic quoted me at $7,000 for parts and labor and it's the same updated transmission.

A defect in the 2018-2020 Ford F-150's 5.0-liter V8 "Coyote" engine that causes excessive oil consumption, potentially leading to engine failure, reduced efficiency, and increased emissions. Ford concealed this defect not letting owners know and didn’t issue a recall. The oil dip always reads as if there is not enough oil in the truck causing you to have to constantly top off oil which is always over the usual amount of oil needed. The excessive oil consumption and potential carbon deposits can lead to severe engine issues, including stalling or even complete engine failure. This has caused other issues. This oil consumption defect has been there since I purchased this vehicle causing oil changes sooner than needed. A manufacturing defects in the 2018-2020 Ford 10R80 10-speed automatic transmission, commonly found in newer F-150 trucks, causing issues like harsh/erratic shifting, jerking, and power loss. The erratic shifting and power loss can pose a safety risk, especially when accelerating, merging, or in traffic. Ford concealed this defect not letting owners know and didn’t issue a recall. I also, have had transmission defects that has needed repairs and replacement due to Power-shift dual-clutch, harsh shifting and power failure. My trucks have had two transmission major repairs. The first time on 9/6/22 at 36,541 miles the whole transmission had to be replaced completely due to powertrain or reduced engine power. Then again on 9/20/25 at 62,948 miles same issue Powertrain (wrench symbol) on the supposedly new transmission this time Ford dealership said it was the transmissions Dual clutches. This i didn't understand why was it happening with a new transmission and always met with an I don’t know these things happen by Ford attendants. This caused to go without a vehicle for months having to use public transportation, loss of money, and time from work. Again, none of these defects were explained or recalled.

Ford had two recalls on 2018 F-150. My vehicle had both issues and was not part of the recall. They had a cam phaser recall that caused timing chain failure if not addressed and excessive oil consumption recall.

The timing chain failed and caused damage tonthe engine. The engine has to be rebuilt or replaced for 10k-12k in cost.

I purchase a 2018 Ford F150 on [XXX]. One week later I am experiencing truck not wanting to shift out of first gear. The shifting is hard and jerking. It jerk so hard that if my son and I didn’t have our seat belt on we would have hit the dash. It periodically will shift from the 9 gear to 1 then back to 4th & 5th gear. It’s I almost got slammed by the car behind me. It is scary I took it to a shop and a total transmission replacement needs to be done I reach out the dealership that told me before I purchased it, all used vehicles go through a thorough inspection. I trusted the dealership and purchased the truck. Under further investigation I contacted where the truck was serviced last and they did an oil consumption test because it is burning a lot of oil. The dealership refuses to help. The transmission is definitely a safety hazard I haven’t even had it a month and I can barely drive it. It my only means of transportation. I have reoccurring monthly doctors appt for my son. It is completely unsafe and can cause a deadly accident for my self and to other around me. Thank you for your time.

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. FORD please fix this issue. Oil leaking from pan first noticed during stops at red lights while idling and smelling burning oil thru vents. Ford dealer confirmed oil pan leak and suggested immediate replacement.
