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.

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.

Despite following Ford-??s instructions step-by-step and investing hours into multiple calls with the Customer Service Division, we were given the runaround and ultimately denied assistance, even though: -??This is a known defect with the Cam Phaser, CSP issued for our vehicle. -??We attempted to have the repair performed within the CSP period but were delayed due to pandemic-related part shortages and poor dealership follow-up. -??Our warranty expired less than 30 days before diagnosis. Our documented timeline: -??July 25, 2022 -?" Brought truck to Courtesy Ford for PCM reprogram under 21N03; told parts were backordered due to pandemic. After a week, we had to reclaim the truck for work needs. Service was poor, with no follow-up. -??November 2022 -?" Returned truck; again no resolution or follow-up. -??January 1, 2023 -?" Ford extended CSP under 21B10; still no symptoms at this time. -??May 28, 2025 -?" Private shop diagnosed Cam Phaser failure; quoted ~$5,000. -??August 2025 -?" Chose Canby Ford for better service; diagnosis confirmed repair needed at $5,225.18. The three calls to Ford Customer Service: 1.Call 1 -?" Opened initial case, told to bring truck for cold start diagnosis. 2.Call 2 -?" After delivering truck, spent an hour on hold and -??updating-?? records; told CSP couldn-??t be located and to call back after diagnosis. 3.Call 3 -?" After diagnosis, finally told we were ineligible because warranty expired less than 30 days prior; agent and supervisor claimed they could not override the system. At no point during the first two calls did anyone verify our eligibility or warn that warranty expiration would block assistance -?" meaning we invested significant time, followed Ford-??s instructions, and left our truck on a service lot, only to be told we never qualified in the first place. This is an unacceptable breakdown in process and communication.

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.

- Derby, VT, USA

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.

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.

Vehicle has had regular maintenance. It started rattling at startup and we took in for service. The service department said the 5.0L Ford Motors are pulling more oil than the manufacturer recommends and is causing engine damage up to and including engine failure. Thankfully we took it in as soon as it started making a noise, but that did not save the engine. Now we are facing a $16K repair for an apparent "known" issue about this Ford motor. Ford will not help and said to take it up with NHTSA to try to get a recall for this issue. This seems like a manufacturer defect, but they are not taking any responsibility for this problem.

Complete engine assembly (including internal bearings), twin turbochargers, and water pump. - Failure Mode: While driving at highway speeds, the engine warning lamp illuminated -??Low Engine Oil Level, -?? followed by an audible ticking noise from the front of the truck. Upon shutting the engine off and attempting restart, the engine locked up and would not turn over. - Availability: The failed engine and associated components remain intact on the vehicle and are available for inspection at my local Ford dealership or by any third-party expert. For safety, loss of power steering and braking assist occurred instantly when the engine warning lamp came on, greatly increasing the risk of a high-speed collision. - The engine seized without warning, stranding me on a busy interstate shoulder and creating a serious hazard to passing motorists and my personal safety. - On June 3rd, Ford-??authorized service technicians at Bird Kultgen Ford in Waco Texas, confirmed complete engine failure, twin-??turbo damage, and a failed water pump. - A written estimate for repairs was provided which the amount was in excess of 20,000$ for a new engine, new turbochargers, and water pump. - Completed on June 3rd, with diagnostic report and repair estimate on file. - Manufacturer Response: I sent a certified letter to Ford Corporate on June 23, no acknowledgment or reply has been received in over 14 business days. - No police, insurance adjuster, or other third parties have yet performed an independent inspection, pending Ford-??s response. - Initial Warning: -??Low Engine Oil Level-?? dashboard message appeared at approximately 65 mph on the interstate. - Audible Symptoms: A distinct ticking noise under the hood began immediately after the warning lamp. - No prior oil leaks or dashboard indicators had appeared before this highway incident.

While driving to Sam-??s Club (approximately 20 miles from home), my 2018 Ford F-150 3.5L EcoBoost began running very rough, and the check engine light came on. I had the vehicle scanned, and diagnostics confirmed that the cam phasers are failing -?" the exact issue I had replaced under warranty at approximately 59,000 miles. The vehicle now has just 88,000 miles, and this failure occurred in under 30,000 miles since the original repair. I have maintained this truck with extreme care. I only use Motorcraft parts and fluids, change the oil every 3,000 miles or sooner, and always use premium fuel. This is not a maintenance issue. This is a design or part failure that Ford has not properly resolved. When the phasers were replaced the first time, I was told there was no warranty on the replacement parts. That is unacceptable. A known failure being replaced with an equally defective part is not a resolution. Ford is aware of this issue -?" there are multiple TSBs (including TSB 21-2130 and 19-2208) and widespread complaints across owner forums -?" but they have taken no responsibility. I paid over $44,000 for this truck and should not be facing the same critical engine failure twice before 90k miles. The rough performance and sudden malfunction while driving posed a potential safety risk. I am submitting this complaint so NHTSA can investigate and hold Ford accountable. This seems like a common problem with this engine, and I do not understand why there has not been a recall or why Ford has not been forced to implement a permanent fix.

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.

- Brunswick, GA, USA

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 that should not be the consumers responsibility. Please help get a recall issued.

In November of 2024, my truck was shaking, accelerating erratically, and felt like the transmission was slipping. The check engine light came on as well. I took it to the shop and after diagnosing that it was a misfire issue in cylinder 6, they replaced spark plugs, fuel injectors, and tried to switch out new coils. They found gasoline inside cylinder 6, and upon doing a compression test, it was well below 100%. The truck continued to have misfires in cylinder 6, ultimately leading to 0% compression in that cylinder after taking it back to the same authorship to diagnose. After researching online forums and technical bulletins, it-??s clear this issue is not uncommon among 2.7L EcoBoost engines from this model year, suggesting a manufacturer defect. The cost to replace the engine (as now recommended) has been estimated at nearly $10,000. With the history of regular oil and maintenance by the previous owner and myself, I feel this is a manufacturing defect that could potentially cause harm to the driver and passengers.
