2018 Ford F-150 Owner Complaints

Driving highway I70 over Vail Pass, vehicle downshifted on it's own nearly causing someone to rear-end my vehicle. Took it to three local automotive business's for a diagnostic service; they all reported the same issue PP07F7-00 CDF drum and the 10th-gear not engaging. This should not be occurring when I've maintained service of my vehicle. I've paid for one diagnostic and shouldn't have to pay for one at my Ford dealer where it was purchased by I will have to again. I know of several owners with the exact same issue and no one is supporting them for this. I've owned four Ford trucks and this is unacceptable. Ford Case# CXH-09395547-R9D3S2

2018 Ford F-150 Limited with the 3.5L EcoBoost engine. At approximately 60,000 miles the engine began making a rattling noise from the front of the engine on cold start, lasting several seconds. Over the last three months the noise has become progressively worse and now occurs at every cold start and lasts longer. The check engine light is currently illuminated. The vehicle has not stalled or lost power. A Ford dealer (Wynne Ford, Hampton, VA) diagnosed the condition on September 24, 2026 at 104,661 miles as cam phaser failure, requiring replacement of the variable camshaft timing (VCT) units and associated timing components. This matches Ford's Technical Service Bulletin 23-2143, which covers 2017-2020 F-150 vehicles with the 3.5L EcoBoost engine built on or before November 30, 2019. Ford previously issued Customer Satisfaction Program 21B10 and warranty extension 21N03 for this same defect on March 2, 2021, but 21N03 expressly excluded the F-150 Limited trim, and both programs have since expired. The dealer additionally reported that it has submitted multiple other cam phaser repairs on 2017-2020 3.5L EcoBoost vehicles for manufacturer assistance in the past two months, including vehicles newer and with lower mileage than mine, and that all were denied. The quoted repair is $5,414.11 at my expense. I am filing this report because cam phaser failure in these engines can progress to timing chain damage and engine failure, and because Ford has documented this defect since at least 2021 without issuing a recall. I contacted Ford (case CXH-09424982) and was denied any financial assistance.

The 10-speed automatic transmission (10R80) shifts harshly and erratically, hangs in gear, and lost 2nd gear entirely, causing unpredictable acceleration and gear engagement in traffic. First reported to a Ford dealer on 6/8/2021 at 25,883 miles (dealer called it normal). Repairs: internal teardown at 32,920 miles (damaged clutch, input shaft, torque converter hub); valve body repair under TSB 24-2101 at 63,483 miles; CDF hub and friction plate failure diagnosed at 77,584 miles (TSB 25-2126 failure mode); loss of 2nd gear at 88,449 miles. Pre-repair scan 9/2026 shows P0732, P076F, P07F6 (incorrect gear ratio, gears 2, 7, 9). Transmission being rebuilt again 9/2026. The engine also suffered timing chain and crankshaft failures requiring a full engine replacement at 66,108 miles and another timing repair at 77,584 miles. Three catalytic converter failures. Nearly 200 days in Ford dealer service departments.

2018 Ford F-150 XLT Power Train / Transmission (10R80 10-Speed Automatic) ~100,000 miles (99,737) While accelerating, typically at neighborhood speeds, we sometimes get a hesitation/delay in shifting, which causes a pause and then a hard shift jerking forward, which makes it unreliable at times. Not getting any dashboard warning lights, and has had the transmission flushed at 80k miles by a Ford dealership. A Ford dealership diagnostic inspection confirmed an internal mechanical defect: a failure/migration of the internal Teflon-sealed sleeve on the CDF clutch drum. The dealership technician also noted harsh upshifting between gears 3 and 4, and harsh downshifting between gears 6 and 5. The sudden, unpredictable loss of power during low-speed acceleration creates an immediate safety hazard. It leaves the vehicle vulnerable to rear-end collisions when merging into moving traffic, navigating busy intersections, or pulling out onto roadways, as the truck fails to accelerate when commanded. Furthermore, the violent gear slamming can cause momentary loss of traction or driver distraction under low-grip road conditions. Researching, what we're experiencing is very common with the 10R80 transmission that we have, and documented in TSB 23-2152, and TSB 25-2126. From what I'm reading, Ford redesigned the CDF drum in 2023 to try and correct the manufacturing issue.

While driving my brakes went from normal, to squishy, to total loss of brakes. Brake indicator light came on while in the squishy phase. After avoid collision by nothing other than sure luck I was able to slow the vehicle and use the emergency brake to stop. Once stopped I popped the hood and found the master cylinder to be all but empty. I obtained brake fluid, filled the cylinder and the brakes appeared to be normal. After a very short drive I lost brake function again and the MC was empty. No leaks could be found from lines or around the wheels Truck was towed to an independent shop where the diagnostic determined the master cylinder seal had failed and leaked brake fluid into the brake booster. I believe the Hitachi master cylinder failure is a known Ford defect. It has been recalled on the 3.5L model F150's but not the 2.7L and 5.0L models. My loss of brakes could have led to serious or fatal traffic incidence. The master cylinder is defective on all models of the years involving the recall of the 3.5L models. The recall should be extended before someone loses their life. Please look to extend the recall to include the other models of F150s.

The contact owns a 2018 Ford F-150. While approaching a light and entering a loop while driving 55 MPH, the transmission unexpectedly shifted from 7th gear to 1st gear. The vehicle stalled, was shifted into park, and restarted. There was vibration in the floor at the time of the purchase. The vehicle was taken to the local dealer, where the torque converter was repaired under warranty. The vehicle was taken to the local dealer again, where it was diagnosed and the failure was associated with the valve body. There were no codes present. The vehicle stalled on Interstate I-20 while driving 60 MPH, causing an unsafe situation. The wrench symbol was displayed after the failure. The vehicle was taken to a transmission center for a scheduled repair. The contact associated the failure with NHTSA Campaign Number: 25V164000 (Power Train). The manufacturer was contacted on two occasions, and the contact was provided a case number. The failure mileage was approximately 108,000.

After Fords TCM recall the truck’s transmission has not acted correctly, very hard shifts, staggered shifting and warning lights for shifting issues or low power due to loss of signal from computer. It has gotten worse it now is sticking in 4th and 7th gear, acts as if slipping and completely stopped the truck in a busy intersection where I had to shut the vehicle off and restart before it would go in gear manually. Truck has lunged forward in reverse, went into low gear on the interstate and have given codes for fault detection. I’ve had the vehicle look at by a certified mechanic and his computer shows no connection between computer and transmission then shows partial connection and the full connection. Torque Converter shows good and so do the cliches and solenoids. This is dangerous and could cause an accident if not fixed, whatever ford’s update was has made my computer loose connection with the transmission and has put a fault that could possibly cause an accident or fire.

My 2018 Ford F-150 experienced significant heat damage involving the fog lamp assembly. The fog lamp did not simply stop working. The assembly became hot enough that portions of the lamp/assembly melted and burned. I discovered the damage before it resulted in a larger vehicle fire, but I am concerned about the potential fire risk associated with this failure. The vehicle was taken to a Ford dealership, where the damaged fog lamp assembly was identified and replacement was recommended. I am reporting this because the amount of heat generated and the visible melting/burning appear to represent a potential vehicle safety and fire hazard. I have requested that the Ford dealership document the damage, photograph the affected components, and report the issue to Ford for review.

The 10 speed transmission does not shift smoothly and will periodically shift hard when downshifting from 4 to 3 and 3 to 2. Ford is aware of bushing walking which they addressed in 2022. I am one year out of my warranty which Ford would not address when under warranty but issue was less of an issue. Now that it is routinely shifting rough, they will not stand behind their transmission they knew was problematic. I have on numerous occasions been almost rear ended because they hard shift mimics a hard braking without warning.

SAFETY HAZARD & RISK ​The 10R80 transmission exhibits sudden, unpredictable gear slipping, power loss, and violent slamming/lunging during gear shifts while navigating active traffic. This erratic behavior creates an immediate collision risk when merging, accelerating, or changing lanes, as the truck unexpectedly loses momentum or lunges forward. ​INCIDENT & REPAIR HISTORY ​The vehicle required two complete transmission overhauls under 68,000 miles at Apple Ford (Columbia, MD), both confirmed by certified technicians and warranty inspectors: ​Overhaul #1 (Invoice #273111 | Aug 14, 2024 | 42,571 miles): Diagnosed under TSB 24-2101 for shift failure. The dealer overhauled the valve body and replaced internal components, including the CDF drum (Part #JL3Z7H351B). ​Overhaul #2 (Invoice #351672 | Sep 11, 2026 | 67,587 miles): Less than 25,000 miles later, severe slipping and 5th gear binding recurred. Teardown revealed a sticking main pressure control valve, burnt E & F clutch packs, and an outdated CDF drum. The dealer replaced the complete valve body (Part #JL3Z7A100CRM), installed a redesigned CDF cylinder (Part #PC3Z7B177A), and replaced scorched clutch/steel plates. ​COMPLAINT RESPONSE SUMMARY ​System Failed: 10R80 Transmission (CDF drum sleeve migration, sticking valve body, burnt E & F clutches). Vehicle is available for inspection. ​Safety Risk: Sudden power loss and violent lunging in active traffic, creating severe collision hazards. ​Confirmed by Dealer: Yes. Diagnosed and verified twice by Apple Ford master technicians. ​Inspected By: Authorized Ford dealer technicians and an official warranty company inspector. ​Symptoms/Timeline: No warning lights appeared prior to failure. Physical symptoms (slipping, violent slamming) first appeared before Aug 2024 (42,571 miles) and recurred in July 2026 (67,587 miles).

I have a 10 speed automatic transmission that intermittently works in 2nd and third gears. It began doing this at 60,000 miles. I'm not sure if it is the adaptive learning transmission control module (TCM) or the transmission itself. Ford dealer wants over $10,000 to replace transmission. The car is unsafe when pulling into traffic and it won't accelerate half the time.

My Ford F-150 Supercrew XLT 10R80 10-speed completely failed resulting Ford replacing it with a new transmission unit for a cost to be of $7,300. As the transmission failed at 96,000 miles the gears would be skipped with harsh shifting, not fully engaging 4th gear and at times while driving would refused to shift into any gear and high revs and me unable to accelerate. I was nearly involved in a crash when I would pull out into traffic legally but suddenly unable to accelerate and approaching cara from the rear needed to suddenly brake and change lanes to avoid a collision. All diagnosis was conducted by Ford. At first it cost me approximately $300 for them to drain and fill transmission fluid. When that didn't fix the problem they then said it was the DCF drum failure at a cost of $5000. When they were unable to fix it they informed me that they needed to install a brand new transmission at a cost of $7,300. Current mileage is approximately 98,300 miles. As a prior certified LEO Traffic Homicide Investigator, I was terrified driving the truck knowing what could happed if it failed as I was crossing traffic or pulling out and fail, as is had already and therefore I was unable to use my vehicle.

1st problem transmission: Hard shifting up and down in certain gears. 3 gear seems the worst. When slowing down to almost stop it down shifts and lurks forward which can cause a safety issue. Loud banging noise when it does this hard shift. 2nd problem when starting the truck up get a loud chain rattle. Think it’s the phaser/cam rattle I keep reading about with no fix. Mileage on my truck is 63,000 miles never tow or haul anything. Crazy ford can sell something like this and be ok with it.

Incident

Aug 29, 2026

Direct failure of Cam phasers and confirmation. This led to erratic engine runtime leading to transmission shifting learned behaviors based on the bogus engine information. This causes erratic hardshifting into drive and most importantly dropping gears on the highway resulting in unsafe driving conditions at random. This includes both random downshifts at highway speed and a similar situation when accelerating the wrong gear is engaged both causing unsafe conditions for the driver and those surrounding. Upon phaser replacement the engine then ran correctly and transmission was reset both KAM tables and learned behavior to rectify the transmission safety challenges. This should at least be a TSB not just a mystery to owners and dealers alike.

I own a 2018 Ford F-150 3.5L EcoBoost with approximately 93,000 miles. I am experiencing a repeated cold start cam phaser rattle. This is a known issue addressed by Ford in several TSBs, including 19-2365, yet no recall has been issued. It has been "repaired" once at approximately 40,000 miles only to have the same issue reoccur at which time I was told that rattling at startup is "normal" and "since it doesn't persist it is not an issue". No IC gasoline engine should rattle on startup, and I believe this defect poses long-term reliability concerns and will lead to engine damage and failure during operation. Ford should be held responsible for a widespread design flaw affecting thousands of vehicles. I urge the NHTSA to investigate this recurring issue and hold Ford accountable for consumer safety and financial impact.
