2018 Ford Expedition Powertrain (other) Problems

Failing Transmission, does not shift into the gear just hear grinding noise, after few seconds of it, transmission makes very hard shift. This takes place in all phases or driving leading to potentially very dangerous situation of the car not moving or stopping while crossing a street with upcoming traffic, crossing intersection or any other phase of driving. Visited few shops and was advised that Ford has a major problem with 10R80 Transmission and failing CDF Drum.

The heater hose that feeds the front and rear heater cores ruptured while traveling at highway speeds on a main road. The engine coolant directly sprays onto the engine resulting in a steam cloud that can not be seen through, also rapidly overheating that motor. This caused a dangerous scenario where the driver can not see the road correctly through the steam cloud while trying to pull off of the highway with the engine over temp warnings flashing in the screen further adding to the panic.

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 NHTSA 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.

I’ve had multiple instances happen but the two latest are — traveling down the highway when I switched lanes and accelerated moderately. The expedition downshifted and I heard a massive clunk. I had no power. Started coasting and adjusting myself so I could get to shoulder, and it shifted back into gear. Another instance, I was at a stop sign turning left onto a highway as I turned out onto the road, I had no power and it wouldn’t accelerate while a vehicle was quickly approaching from behind. I had to coast onto the shoulder to avoid being hit before it got power and carried on. These conditions create a significant safety risk because the vehicle may fail to accelerate when entering the highway, merging into traffic, crossing traffic, making left turns, or avoiding hazards.

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.

While driving on the interstate and merging to the next lane, my transmission shifted from 9th gear to 1st gear multiple times. My safety and others safety was put at risk due to the car suddenly slowing with no brake lights to indicate I would be slowing. During the incident, I lost approximately 5-10 miles per hour forward speed. The problem has not been looked at or replicated by a dealer at this time. This happened today, 7/2/2026. There have been no warning lamps or other symptoms to indicate a 9th gear to 1st gear change at highway speeds.

Incident

Jun 1, 2026

Transmission will randomly over shift or down shift when driving. When turning left I have had the transmission over shift from 2nd to 8th causing the car to bog down and could not accelerate in the intersection. I was almost hit from behind on one occasion and had hit on the side another time. I do not feel comfortable making turns without having a protected right away. Ford have changed the transmission, reset the programming for the transmission and ford technician said it needed to be replaced by again and Ford denied even though it was under warranty and just reset again. If reset it does go away for a bit but just event returns and only gets worse

Incident

May 4, 2026

The transmission was shifting into neutral while driving, causing hesitation with oncoming traffic approaching, at one point it actually shifted into park or reverse while driving in forward gear. We could easily been stalled or lost forward motion with the intent of thinking we were OK to proceed thru oncoming traffic, which would result in collision or accident, jeopardizing our safety or our grand children in car seats safety. The car was taken to Ford dealership and they said there were no codes on the autos computer and that the car would not reproduce the failure, however up on bringing the vehicle home it continued to slip into neutral while driving. The first failure started in October 2025 and was taken to the Ford dealer for repair in November 2025. I contacted Ford Regional Management and they gave me a case #CXH-07154008-P4F3D0 in February 25, 2026

Incident

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

Incident

Mar 20, 2026

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.

The vehicle often feels like it is slipping when it is changing gears at lower speeds. When trying to accelerate quickly getting on the highway, it fails to increase speed. The gas pedal is pressed and the engine revs and it does not increase speed. This has happened more than once and has caused me to nearly be in accidents because I cannot enter the highway as I should. I took it to a dealer initially in 2023 and they repaired the transmission cooler. Was told it was operating as designed after that. Then in 2024 I took it in for the same issue and was told I needed an engine replacement. I paid for an entire engine replacement and was told the issue was fixed. I am now having the same issue and will be taking it back for a 3rd time. My local shop (not the dealer) told me it is the timing belt which is part of the engine. I feel unsafe in my vehicle and do not feel my $16,000 repair fixed the problem.

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 NHTSA 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.

When attempting to pass a slow moving vehicle on a 2 lane highway when driving up a hill the transmission failed to properly shift instead making a loud clunking and grinding sound before eventually managing to shift into a gear. This failure to shift properly meant that the vehicle was unexpectedly without power when trying to change lanes leading to a dangerous situation.

Incident

Dec 19, 2025

The contact owns a 2018 Ford Expedition. The contact stated that while driving over 40 MPH, the vehicle stalled on two occasions. The contact stated that while driving a roundabout, the vehicle lost motive power. The accelerator pedal was depressed, but the vehicle jerked and was sluggish, and there was no area to pull over to. Upon parking the vehicle, the power train warning light was illuminated. The contact called an independent mechanic who was unable to service the vehicle. The vehicle was taken to the local dealer, where it was diagnosed that the vehicle was jerking due to the CS drum and transmission failure. The vehicle was not repaired. The dealer was not contacted regarding the latest symptoms that the vehicle had displayed. The manufacturer was contacted, but no additional assistance was provided. The failure mileage was approximately 93,000.

My vehicle has started to have problems shifting in some gears(3rd & 7th). I have been doing research, and this seems to be a recurring problem for vehicles with the 10r80 transmission. Where this has caused a big safety risk, is that a few times, the vehicle wouldn't move when pushing on the gas after having the foot on the brake after I had already left and been driving it for 5-10 minutes. This has put me at risk of getting hit by oncoming cars since I couldn't get the vehicle to go as it should to cross a road or intersection. My vehicle shows no dashboard warnings that anything is wrong. I have had all regular maintenance done, don't use the vehicle for towing, and I only have 70k miles on the car. Over the years I have had it where it just feels like the vehicle won't shift, but it has gone away pretty quickly. It's only been since this summer that it is now a persistent issue. I have brought it up over the years to the ford service department, and nothing was shared with me that there was an issue with the vehicle transmission. It is now that it's been consistent(only when the transmission is cold) that this happens on every drive. All Ford wants to do is charge me to rebuild the transmission conveniently now that I am out of warranty!

Nov 24, 2025

I was driving down the road at 45 MPH, I pushed the accelerator then my vehicle shifted out of drive to neutral, the RPM increased, the car speed decelerated, then the vehicle put itself back in gear severely downshifted so much that my car lost 20 MPH then the engine returned to normal after a violent shake and loud grinding noise. The car could have caused an accident had there been anyone behind me. Luckily there were no other cars around me. I had the vehicle towed to the dealer. They are unable to duplicate the issue I stated but did indicate a skip in cylinders when they hooked it up. I had the transmission overhauled at 53K when it was not shifting properly. I asked Ford to replace the transmission however they elected to overhaul it. From time to time the transmission would shift odd but nothing of over concern. The incident on Nov 3 was very unusual and safety of travel for me. The vehicle had done something similar earlier that morning but that time it was from a stop and no speed so not nearly as violent as the one later that evening. The vehicle is currently sitting at a dealer needing a transmission replaced, however the vehicle is 500 miles over the 75K ESP. Ford is refusing to discuss the problem.

The transmission started jerking and downshifting and and like the brakes was coming on and stoping you and I was pulling out onto the road and it wouldn’t go and I was setting in the middle of the road with oncoming traffic and scared for my life, luckily I didn’t have anyone with me and it moved a little and I was finally able to get it out of the road. This is the problem everyone is having FORD you need to recall these transmissions and replace them with new ones that are better this is a shame and bad business. It is hard enough to afford buying vehicles in this day and time and then it need a transmission that is expensive to replace.

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.
