2018 Ford Expedition: engine knocking or ticking

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.

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.

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
