2018 Ford F-150: engine failure

Filed Nov 5, 2026 · Engine · KY

I own a 2018 Ford truck with 77,000 miles. My truck has just experienced the widely recognized cam phaser failure—a known design defect that can cause a catastrophic engine failure to occur. Because this is a known manufacturing defect that Ford addressed with updated parts, TSB 23-2143 (or TSB 21-2119): These are the official internal Technical Service Bulletins that explicitly instruct Ford technicians on how to diagnose and repair the "cold start ticking/tapping or rattle type noise" on 2017–2020 F-150s with the 3.5L EcoBoost engine. It confirms the root cause is a worn Variable Cam Timing (VCT) unit and outlines the procedure to replace all four phasers. [1, 2] Customer Satisfaction Program 21N03: While the prorated financial assistance under this program expired in January 2023, the document itself remains critical. It serves as corporate documentation where Ford explicitly acknowledges a manufacturing/design flaw in the original cam phasers. Ford refuses to replace or reimburse this repair for any vehicle that is out of warranty. This is a known safety issue acknowledged by Ford and it should be addressed as a safety concern and recalled.

The VVT Cam Phasers had a " consumer satisfaction program" that didnt include my VIN but included the year which was 2017-2021 3.5 ECOBOOST engine that mine has. The program has now expired and my truck has this exact issue. Not fixing the issue can cause engine failure. My truck has 47k miles on it. I called Ford back in XXX to file a compliant and nothing happened. I took my truck to Germain Ford in [XXX] to get a diagnostic done October 5,2026 and they said it was the VVT cam phasers. I called Ford XXX again about the issue and they said my VIN wasn't included and there was nothing they could do. This is absolutely absurd they are ignoring an ongoing issue and they refuse to do anything about this. I will continue to fight until something is done. This repair is costing me $4400. This is where you can help. Please make them do the right thing and reimburse me and I'm sure so many others their money.

My truck has the 3.5 ecoBoost twin turbo engine with the known cam phaser problem. Ford dealership replaced cam phasers 4 years ago and told they were putting in new designed cam phasers to prevent this from happening again. Last week, I changed the v v t cylinder because of a p0018 code, and found that the replacement was the old cam phasers prone to break again. Truck is just now out of warranty. And ford is doing nothing to help. Drivability is not the same has hesitation. So far, and I'm sure it's going to get worse. Check engine light just went on last week. This truck is at dealership now. My biggest problem with this situation is Ford. Dealer lied said they put in new cam phasers, which they put in old ones. I would have got an extended warranty if I knew they were the old cam phaser. Now, I will be out 3 to 5 thousand dollars because ford dealership lied to me. I have all paperwork. Service reports everything on the truck. The truck was babied. There's no reason why in 70000 miles catastrophic engine failure twice. Fixing the problem with the same problem. Parts is not a fix. It's a bandade until warranties are over. And let the people deal with it.

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.

multi-component engine failure while being operated under normal driving conditions. ​Despite rigorous, routine, and fully documented preventive maintenance performed in accordance with manufacturer specifications, the vehicle suffered an instantaneous breakdown of its core mechanical systems. A diagnostic assessment confirmed that a sweeping array of vital engine components—including the cam phasers, turbocharger, lifters, timing chain, and associated valvetrain assemblies—all failed simultaneously. ​Rather than a progressive wear-and-tear issue or a failure caused by neglect, this unprecedented, all-at-once collapse points to a massive, systemic mechanical breakdown. This has rendered the engine entirely non-functional and requires a complete overhaul or engine replacement.

I am reporting a persistent safety issue involving exhaust fumes entering the passenger cabin of my 2018 Ford F-150. The vehicle was purchased January 20, 2025 and has since experienced repeated mechanical failures and extended repair attempts. Despite extensive work completed under warranty - including a transmission rebuild, full engine replacement, alternator/battery/starter replacement, rear main seal repair, transfer case repair, and transmission pan repair - the exhaust odor inside the cabin has never been resolved. The odor is strong enough that passengers have experienced headaches and nausea while the HVAC system is operating. The vehicle has spent well over 150 days in repair facilities since purchase while technicians attempt to diagnose and repair the issue. The dealership currently still has the vehicle and has not been able to identify or fix the cause of the exhaust fumes. This condition raises serious safety concerns regarding possible exhaust or carbon monoxide entering the cabin. I am requesting that this issue be documented and reviewed as a potential safety defect.

The contact owns a 2018 Ford F-150. The contact stated that when the vehicle was started in the morning and shifted into drive(D), the vehicle hesitated and then jolted into gear. The contact stated that the failure was intermittent but had become a recurring failure. The contact stated that the vehicle was also slipping out of gear. While driving 45 MPH, the transmission downshifted to 1st and the vehicle slowed down unexpectedly. There were no warning lights illuminated. Additionally, while driving at various speeds, the engine was making an abnormal clattering sound. The vehicle was taken to a local independent mechanic, who diagnosed the vehicle and determined that the transmission needed to be replaced, and stated that the cam phasers were possibly causing the engine to make an abnormal sound. The transmission was replaced; however, the engine failure was not diagnosed or repaired. The contact received notification of the federal safety agency Campaign Number: 25E070000 (Power Train). The manufacturer was informed of the transmission failure and advised the contact that no support would be provided for the repair prior to receiving the recall letter. The failure mileage was approximately 70,000.

I was not in an accident. I have a 2018 ford f150 xlt and it has a 3.5 eco boost. My truck is leaking some type of oil from the top and has very bad fuel injectors which is why my truck cant accelerate and shakes extremely bad. When I sit at a red light my truck dies and I think i have a leaking exhaust. I bought a new battery but it still dies. I know they used to do a recall for a new engine from what i’ve searched but they don’t do it anymore and I don't think its safe for me driving while I have all those problems. I have not been in an accident but with all these problems my truck could possibly die or go out while i’m on the highway and just makes me nervous driving something like that when the 3.5 eco boost is already not a great engine. Thank you
