What owners say about the engine
Verbatim from NHTSA complaints, newest first
“I was traveling on the interstate and went to accelerate to pass a vehicle. My car displayed system fault codes and made a clicking noise and dropped to neutral while my RPMs stayed high. I lost acceleration and had to swerve to avoid a collision. The engine then had a loud clank and jerked into gear. Once I had pulled off enough I turned the car off and on again and resumed driving. This has happened multiple times. Each time when I have contacted Ford they say it’s a known issue with the make of the Clutch drum and realized the issue after the 2022 year and changed the way it was made. However they stated it would cost me over $6500 to repair mine. They do not accept fault only state it is a known issue. When my car goes from 65 to 39 in a span of a few seconds it is a huge safety issue.”
“Vehicle was disabled multiple times after failures of the OEM coolant / heater hoses at plastic fittings. Hoses includes the primary radiator coolant hoses, bypass hoses and engine coolant hoses for the transmission cooler. First hose failure on 10/21/2022 (51,177) miles was repaired by Ford dealer in Davenport, FL. OEM replacement hoses have also failed.”
“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…”
“I noticed a loud rattle when starting my 2018 Ford Expedition, at first occasionally and then on every cold start. The Ford Dealer's service department diagnosed a cam phaser issue. There were no warning lights or messages available to me, but the service department's diagnosis showed several timing faults. I was told the cam phaser repair is $4000 - $5000 and continued use puts the engine and transmission at risk. I contacted Ford customer service and was told that my vehicle was not eligible for assistance with these repairs and that my level of loyalty also did not make me eligible for assistance. I have maintained this vehicle with oil changes, fluid changes, tire and brake maintenance for the life of the vehicle. I would like the NHTSA to investigate Ford for a recall of the cam phasers and effected parts since this is a known and prominent issue that also impacts road safey.”
“Engine light stays on along with manual light and charging system service now. Battery, alternator changed out, 3 mechanic repair shops can not find what is wrong. Vehicle bogs down and does not run right when the Manuel light comes one which is about 2 times a week.”
“After Fords most recent recall for a PCM software update at the dealer the car immediately runs different and after full engine temperatures sounds like marbles or valve train issues including low rpm noise and transmission shutter between shifts. Dealer says there is no problem they can find and that I need new turbos. Very suspicious that after a PCM flash the car is now unable to drive. The car had NO issues prior to recall service and only has 70,000mi”
