2018 Ford Expedition: sudden loss of power

Filed Sep 11, 2026 · Engine, Transmission · SC

My 2018 Ford Expedition with the 3.5L EcoBoost engine has developed a pronounced rattling/knocking noise at startup. This appears consistent with the well documented cam phaser/VCT problem affecting this engine family. At approximately 118,212 miles, an independent Firestone Complete Auto Care inspected the vehicle and recommended major timing system repairs. Their estimate calls for replacement of the timing chain components and variable timing sprockets/cam phasers, with a total recommended repair cost of $5,232.13. 220782OrderRevisions.Pdf The concern is not simply the noise. The cam phasers and timing system control critical valve timing. If these components continue to deteriorate, there is a risk of improper engine timing, severe drivability problems, loss of power, stalling, or significant internal engine damage. A failure while traveling at highway speeds or in traffic could create a serious safety hazard for the occupants and surrounding motorists. There have not yet been warning lights or dashboard messages associated with the condition. The primary symptom has been the recurring startup rattle/knock, which has now been confirmed by an independent repair facility as requiring substantial timing system repair. The vehicle remains available for inspection. This has been an ongoing issue for the last few months but was first diagnosed on September 12, 2026 during a repair for another unrelated issue. I am especially concerned because this is not an isolated or unusual type of failure on the 3.5L EcoBoost. Ford has previously recognized cam phaser/VCT startup noise on these engines through service guidance. A known timing-related defect requiring more than $5,000 in repairs, with the potential to progress into engine damage or loss of engine performance, represents a significant reliability and potential safety concern.

I am submitting this complaint regarding potential safety issues with my 2018 Ford Expedition Max Platinum. I purchased the vehicle from Sandy Sansing Chevrolet in Pensacola, Florida, and discovered several problems shortly after purchase that I believe may affect the vehicle's safe operation. Within days of purchasing the vehicle, it began displaying an intermittent **low oil pressure warning** while driving. Because a low oil pressure condition can lead to engine damage, loss of power, or engine failure, I believe this presents a potential safety concern. The dealership's inspection report completed before the sale states: **"Has multiple minor oil leaks, wet but not dripping yet."** I had the vehicle independently inspected by Firestone, which determined the oil leak was coming from the timing cover/timing case area and estimated approximately $3,000 in repairs. I am concerned that the documented oil leak and intermittent low oil pressure warning could increase the risk of engine failure while the vehicle is in operation. I have also experienced what I believe is a brake safety concern. Although the dealership's inspection report indicates the brakes and rotors had been serviced, the brake pedal feels unusually soft or spongy and requires more pedal travel and pressure than expected before the brakes engage. While the vehicle currently stops, I am concerned this condition could reduce braking performance or increase stopping distance. Additional issues include intermittent operation of the power running boards, a non-functioning rear window washer, and a detached rear window defroster electrical connection. I am submitting this complaint so the federal safety agency can determine whether these issues are isolated to my vehicle or may indicate a broader safety-related defect affecting other 2018 Ford Expedition vehicles. I can provide the dealership inspection report, Firestone inspection and repair estimate, photographs, and other supporting documentation upon request.

Vehicle experienced catastrophic timing system failure causing engine to jump time and stall at idle, creating a safety hazard due to risk of sudden loss of power. This is a repeat issue originally documented under warranty (2020) and again during recall/service program 21N03 (2021), where repair was declined as “not severe enough.” Recall 24E13 (software update intended to prevent timing chain failure) was completed in 2025, but failed to prevent this exact condition. Vehicle is now inoperable and unsafe. This raises concerns about the effectiveness of the recall remedy and prior service handling. We've also submitted a case to Ford: CXH07545978W9W1D2

While driving at approximately 55 mph, the vehicle intermittently loses throttle response. Pressing the accelerator results in no increase in RPM or vehicle speed, even when the pedal is fully depressed. After 3–5 seconds, power suddenly returns. The issue consistently occurs after the vehicle has been driven for about 20 minutes and is at normal operating temperature. During some events, a “Powertrain Malfunction / Reduced Power” warning with a wrench indicator appears. The vehicle is equipped with the 10R80 10-speed automatic transmission. The failure occurs during steady highway cruising and creates a serious safety concern, as the vehicle will not accelerate when needed for merging or passing. A buzzing noise is heard during the loss of power, and engine RPM remains steady with no response to throttle input. This intermittent loss of power at highway speeds presents a significant safety risk.

At approximately 100,500 miles, my 2018 Ford Expedition XLT 3.5L EcoBoost developed loud rattling noises consistent with cam phaser failure. Zeigler Ford confirmed the failed cam phasers on October 20, 2025. These phasers were previously replaced on the vehicle at 51,000 miles on February 10, 2022, at Al Piemonte Ford under the Customer Satisfaction Program 21N03. They used the old phasers HL3Z-6C525-CD which are known to be defective rather than the new updated phasers ML3Z-6C525. Cam phaser failure can cause engine misfires, loss of power, and potential engine damage, creating a serious safety risk, especially at highway speeds. This issue has been reported by multiple Ford Expedition owners, indicating it is not isolated. I request that the federal safety agency investigate whether this defect warrants a recall or expanded coverage for vehicles like mine that exceed CSP mileage limits. My vehicle has been properly maintained, and the failure is due to a known defect in the 3.5L EcoBoost cam.

Since November 2024 to date the transmission has reduced power when trying to accelerate thus being unsafe when trying to pull out into traffic. It also will not engage reverse thus again impeding when in traffic. It appears randomly. Verified software has been updated. Ford is saying complete transmission replacement is needed on a vehicle that is only 7 years old.

2 instances have occured while driving. Stored codes are P0562 Charging system voltage low and P07E6 Stuck in Park (6/6/2025) and P07E6 Stuck in Park (7/12/2025). I believe the issue may be related to TECHNICAL SERVICE BULLETIN - Momentary Neutral-Out Condition In Drive - 23-2120 Upon acceleration to pass a car, I heard a loud knock, lost power, let off the gas, an Engine failure error flashed on my screen, regained power and was then able to accelerate again. The potential cost could be $5,600 and potentially higher due to labor. Ford's have been plagued by transmission issues year after year. How many vehicles need to be affected before a formal defect investigation focused on the 10R80 transmission can be made.

Component/System That Failed: The 10R80 automatic transmission is malfunctioning. It causes harsh shifting, delayed acceleration, hesitation, and unpredictable surging. These issues have been confirmed as part of Ford’s internal TSB 23-2250, which directly references this transmission defect. The vehicle is available for inspection upon request. Safety Risk: This transmission failure poses a serious safety risk. The hesitation and delay in acceleration occur during merging, turning, and highway driving, which can cause near misses and sudden loss of power. The delayed response time compromises my ability to move safely through traffic. Reproduced/Confirmed: Yes. The issue was confirmed by Liberty Ford in Fayetteville, NC, after I paid for a diagnostic. The service department acknowledged the symptoms but refused to cover the diagnosis or repair under warranty since no recall was showing under my VIN. Inspected by Others: The vehicle has not been inspected by the manufacturer directly or by law enforcement or insurance. However, it was diagnosed and documented by an authorized Ford dealership (Liberty Ford in Fayetteville NC). Warning Lamps or Symptoms: There were no warning lamps or error codes. The symptoms began subtly but became consistent over time. The first noticeable event was approximately in “early 2025”, with increased severity since then. I submitted a written complaint to Ford on June 9, 2025, via USPS Priority Mail (Tracking #[XXX]) and also filed a certified safety complaint with the federal safety agency (Tracking #[XXX]) but have received no response. I am requesting formal investigation and recall action. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My wife was driving home from a sports class with my kids in the car. She went to make a left turn against oncoming traffic and the car completely lost power. Pressing the gas did not give any power to the car and the car felt like it was in neutral. if the car did not have enough power at the time of the turn to make it through the oncoming lane, it would have been hit by the oncoming car endangering the lives of the occupants of both vehicles. Our vehicle continued to exhibit the same behavior and I drove it to the dealer. While on the way to the dealer it had 2 powertrain failures before I got it there (30 miles away). The dealership ran diagnostics and said it would be best to get a new tranny as opposed to overhaul since the vehicle only has 90,000 miles and is less than 7 years old. We ended up getting it towed to a local transmission shop who confirmed the diagnostic. They said the seal on the CDF drum plate failed and there was nothing that could be done to stop it. The tranny was rebuilt with all new parts, half a dozen of them upgraded parts from Ford. Upon researching the symptoms, I found this vehicle exhibited a neutral out condition and Ford wrote a technical service bulletin because this issue is so common. I'm frustrated because my family could have been seriously injured or killed because of a known issue that Ford knows about yet chooses to not fix even though this issue puts passengers in life threatening situations. I would not have known about this issue prior to my car exhibiting the neutral out behavior. My local transmission shop has all the parts that were taken out of the transmission and they are available for inspection.

1. The issue involves the transmission and camshaft components of the vehicle. Despite the fact that both the transmission and camshaft were replaced by the Ford dealership after purchase in 2018, the vehicle continues to experience problems. These components have been inspected by the dealership, and the vehicle is available for further inspection upon request. 2. The vehicle’s loss of power during highway driving and while attempting to accelerate poses a significant safety risk. On several occasions, the vehicle has lost power while making turns or driving on the highway, nearly causing accidents with other vehicles. This has been a very frightening experience for us, as the sudden loss of power could have led to a collision. 3. Yes, the problem has been confirmed by the Ford dealership, which replaced the transmission and camshaft components. However, the vehicle continues to run roughly, indicating that the issues have not been fully resolved. These repairs were not covered under warranty, and we had to pay for them out of pocket. 4. The vehicle has been inspected by the Ford dealership multiple times. Despite the repairs, the problems persist. The vehicle has been regularly maintained and garage-kept. 5. There were no warning lamps, messages, or error codes indicating the problem before the failure. However, there has been a loud ticking sound when the vehicle is started and running, which started to occur after the initial repairs. The vehicle has had no other prior indicators to suggest the underlying issue. We purchased the vehicle brand new with only 11 miles on it it currently barely has 70k miles on it. We dropped the vehicle off at the beginning of August 2024 and didn't get it back until almost the end of October, with us needing to bring it back to the dealership for more checks/repairs in December of 2024. We have to pay out of pocket and are without a vehicle because of the constant issues and safety concerns. we can provide receipts and more docs

The car will drop into neutral while on the highway. This happens mostly when trying to accelerate to merge into traffic, down shifting to pass someone etc. Once the car goes into neutral you lose all power. This presents a safety risk as you can be trying to pass someone or merge into traffic and your vehicle stops accelerating. This happened to me when trying to merge onto a busy freeway. I had to pull to the side to avoid getting into an accident. Then once on the side of the road i had to get the car back into gear and then work to merge from a dead stop. Apparently this is a known issue called a neutral out. Once this happened to me the transmission had to be rebuilt.
