2018 Ford F-150 Engine Problems

There was a consumer satisfaction program # 21N03 listed for 2018 f150 2018 3.5L EcoBoost engines and for some reason my VIN wasnt included. I am currently having this issue. My truck has 40k miles on it. Please make them issue a new consumer satisfaction program to include all 2018 F-150 models.

The cam phasers failed somewhere between 60,000 - 70,000 miles. It is a defective part that was subject to a customer satisfaction program in 2020 or 2021 but we purchased the vehicle after this. Now, Ford is saying that we need to pay to replace the cam phasers and the timing belt. It was quoted at $5777.62, which is a significant repair cost. Also, this shouldn't happen with this part and I am seeing everywhere that other consumers are having the same problem, including some at the current dealer we are working with. Any help is appreciated.

Loss of engine oil pressure. Just had engine replaced with used 6 months ago for the same issue. This new to me motor had 40k miles on it. So two motors under 121k miles oil pressure failure. Causing total engine replacement

Failed cam phaser. Brought truck to dealership regarding loud rattling noise on cold starts. Prior to inspection, service technician mentioned it could be the cam phaser because they have had reported problems. Ford did not issue a formal recall but issued a Customer satisfaction program 21B10 to extend warranty coverage due to the known issue but only extended through 2022. I did not have a rattling noise at that time and did not qualify. The noise started recently and there were no warning lights or messages. Only a rattling noise. After the dealership inspected the truck they deamed it unsafe to drive.

The cam phasers have gotten so loud that it sounds like a diesel. Ford did some software "fix" that did nothing. I am concerned about trashing the motor if the timing jumps. These defective phasers are well know problems and extremely costly to repair. Ford has advised me to do the repair but they are quoting $5-6k for a fix of something they know was a defective design. My truck has 111k miles now but the rattle has been there almost from the start.

Engine is ticking and whistling. Drive train issues cam phasers was told beginning of the problem

The long block has failed This has caused the vehicle not to allow for accelleration and have significant power loss. Yes this has been confirmed by the dealer. It has not been inspected by the manufacturer at this time. Two days before I took my trunk into the dealer for service, the service engine light came on. I parked my truck and did not drive it til I called the dealership. They told me to drive the truck slowly to their service department. I drove my truck to them after confirming it was ok. They are 6 miles from my home

V6 eco boost 10 speed transmission is failing with 135,000 miles. Need to be replaced.

there is a know design defect in the cam phaser on the 3.5L EB motors. Ford knows this exists. They have since redesigned the Phasor system to correct this defect. This isn't wear, or use related. It is completely a byproduct of a defective design. The issue is that the repair costs over $7,000, none of which Ford will cover. IT is a known design problem. It is not due to wear, or accident, it is simply an engineering problem. Ford should be required to at least partially compensate owners for this known problem. My motor has less than 50,000 miles on it, and I just spent $7400 getting it repaired. That's about half the cost of a crate motor. It is simply not right for ford to sell a motor with defective compmonents, and expect the owners to pay for their design problems.

Ford issued a service bulletin for a computer adjustment for a known cam phaser issue on the 3.5 eco boost engine while under warranty. This didn’t fix the problem. Now the cam phasers need to be replaced at a cost of thousands of dollars and Ford refuses to do anything to assist even though this was initially reported and taken to the dealer while under warranty. The internet is full of people with this same issue. The vehicle is at the dealer for repairs and they have confirmed this is the problem. Without the repair the engine will fail.

Auto start stop. This has happened on several occasions where I will be traveling at highway speeds and my 2018 F-150 10 speed 10R80 Transmisson with a 5.0-liter motor has died while traveling. I have talked to Ford Engineering reps, and they say they have never heard of this. I have done research into the subject and there have been hundreds of reports of the same issue. I have an appointment scheduled for Ford to look into the issue.

The contact owns a 2018 Ford F-150. The contact stated that upon starting the vehicle, there was an abnormal rattling sound coming from the engine compartment. After the engine had reached normal operating temperatures, the rattling ceased, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the cam phasers. The vehicle was not repaired. After investigating the failure, the contact related the failure to Customer Satisfaction Program: 21N03. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 70,000.

The Cam Phase Shifters and timing chain have failed with only 83k miles resulting in a $7,500 repair. This is unacceptable. I would completely understand if it had 250k miles but this is a baby as far as mileage. Looking at f-150 forums this appears to be a common problem and ford has actually changed the design of the cam phase shifters so they know they are defective. Request you loook into this issue please.

My cam phasers are failing for the third time. I purchased this vehicle used last year at 89,000 miles and now I have 101,000 miles on it. Before I got to 100,000 miles I started hearing a rattle on start up and didn’t know what it was. After researching it by the time, I figured it out I had over 100,000 miles And Ford says they will not do anything about it, although it is a known issue and they had a customer satisfaction program to address it. They should’ve had a recall because it is a severe product defect that if left unaddressed will ruin your engine. It appears from Ford’s records that my vehicle had its cam phasers replaced twice in 2021. And they did a redesign of the part, but they didn’t put the redesign part on my vehicle and it is now failing again. The repair cost at a minimum of $3500. If I don’t fix it, all the mechanics say it will affect my timing and eventually my engine will be destroyed. Yep Ford tries to say it is only a noise issue and they didn’t issue a recall. If you look on any Ford F150 form, this is a well-known well documented issue and probably should be a class action lawsuit at this point.

I own a 2018 Ford F-150 with the 3.5L EcoBoost. It started having idling issues that eventually required the cam phasers to be replaced. While that was frustrating and costly enough, the bigger issue came with the 10R80 transmission. Despite performing all services on schedule and maintaining the truck properly, the transmission failed. After doing research, I found that this isn’t an isolated incident. On Ford forums and owner groups, it’s clear that the 10R80 transmission has been a widespread, ongoing issue for years. Thousands of Ford owners have been forced to spend thousands of dollars to repair or replace these transmissions—something that Ford should have addressed long ago with a proper fix or recall. It’s disappointing that a company with Ford’s reputation hasn’t taken accountability for a known defect that affects so many loyal customers. Something should be done to make this right for owners who trusted Ford to deliver a reliable truck.

The contact owns a 2018 Ford F-150. The contact stated that the oil pan was leaking oil. The contact stated no warning light was illuminated. The contact replaced the oil drain plug but continued to see oil leaking from the oil pan. The contact researched online and determined that there was a design flaw in the oil pan, which was a two-piece oil pan design. The contact related the failure to an undisclosed Technical Service Bulletin, which addressed the failure with the two-piece oil pan by replacing it with a one-piece oil pan that was made of metal. The contact had taken the vehicle to a local dealer, where it was diagnosed, and determined that the oil pan needed to be replaced with a single-piece oil pan. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 183,000.

Cam phaser failure. Has been a customer satisfaction program through Ford which I participated in but was not deemed to have the issue as described. The dealer has now inspected and confirmed it is the cam phaser and the program has expired.

2018 3.5 Ecoboost with plastic oil pan. Ford acknowledges poor engineering and changed production to a single aluminum oil pan half way through 2018 production, but refused to fix the trucks already built. The RTV sealant leaks on the plastic oil pan causing reliabilities and protentional safety issues with the engine components if not caught in due time. Ford issued a TSB 20-2015 report out for fixing the issue. I have been to three ASA certified mechanic shops and all shops refuse to work on the truck. My only option is to go to a FORD dealership and they won't complete the permanent fix of putting in the full aluminum pan. The independent mechanics say they won't work on the truck due to liability issues. They said the truck always comes back to get fixed again. I have done two diagnostics testing with the ASA certified mechanics. They confirmed the oil pan leak as the issue and state reliability/engine safety issues of the truck. There are no warning lights or gauges showing abnormality prior or currently showing. Just a consistent large puddle of oil on the pavement under the truck.

The vehicle is consuming oil at a 1 quart per 1100 mile rate. i have had it tested at a Ford dealer. there is Technical Service Bulletin (TSB) 19-2365 for the year, make and model but Ford isnt offering a repair. The repair is approximately $14,000.00 that should not be the consumers responsibility. Please help get a recall issued.
