2018 FORD EXPLORER Engine Problems

The contact owns a 2018 Ford Explorer. The contact stated that after the vehicle was idling at a traffic stop, the vehicle failed to accelerate as intended while depressing the accelerator pedal. The check engine warning light illuminated. The contact pulled over to the side of the road and turned off the vehicle. The vehicle was restarted; however, the vehicle stalled after driving several minutes. The vehicle was towed to an independent mechanic who diagnosed the vehicle with engine failure and determined that the engine needed to be replaced. The vehicle was not repaired due to the cost. The vehicle remained with the independent mechanic unrepaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 162,000.

- I have experienced a sudden loss of engine power and speed on 5 occasions. Very scary and dangerous to completely lose power on the highway with cars behind you. Had to pull off onto the shoulder(s) in dangerous conditions, with two young kids in the backseat. Hazards, turn off the car, restart the car, etc. - When the power loss happens, the vehicle's dashboard lights turn on, including the engine and wrench icons along with the words "See Manual." - Based on my research, I believe it may be due to a defective throttle body and/or software, related to the "terrain management system." - Problem was not reproduced or confirmed by a dealer or independent service center - No inspections by the manufacturer, police, insurance representatives or others - No warning message is provided prior to the failure, which is another issue

Leaking water pump that if isn’t repaired will cause catastrophic engine failure. Very expensive repair, $2800 because of internal placement of the pump. Since the water pump is in line with the crankshaft and located over the main body of the engine, it allows coolant to leak from the water pump into the oil pan. Mixed coolant and oil will lead to engine failure.

I was driving on a freeway when the engine stopped without warning. The timing chain apparently; slipped and the pistons collided with the alves leaving me stranded on the road. This si a dangerous situation that Ford knows of adn is ignoring. THe car had 101000 miles on it. The car was serviced at 98500 miles by Ford but the timing issue was ignored by the mechanics becasue the computer produced no error codes. The obvious ticking of the engine was the only indication that there was a problem that the mechanics ignored. This is a know premature failure and danger to drivers and the engine should be recalled for repair at Ford's expense. Please issue a safety recall on this engine. ( 3.5L V-Shaped 3.5L Ti-VCT) Consumers are at risk for unexpected breakdowns without warning, at speed, in traffic...

In November 2023, our SUV started to over heat and engine shut off. We noticed the coolant reservoir was bone dry. We added coolant. It was bone dry again within a couple days. We had a mechanic friend diagnose and he told us it is the water pump. We took it to the Ford dealership and we were quoted $3000 to repair it. We could not afford this, so thankfully we met a mechanic that works at dealerships but also repairs on the side. He fixed it for $1000. Flash forward to November 2025 and we notice the heat in our car is not working. Couple weeks later, overheat warning and I'm forced to pull over with my 3 children in the car on a busy highway. Once car cooled down, we went straight home and forfeited our plans. Notice the reservoir is empty again. Refill it. It's empty within...

Another timing chain failure on highway with engine stopping on road. This should be a recall!!!!! Only 101,300 miles on engine. No warnings no check engine lights until after failure.

The internal water pump system on the EcoBoost engine in the 2018 Ford Explorer failed after 7 years and only 63,880 miles. The vehicle was taken into the shop multiple times when the check engine light came on and the defect was not located until the vehicle failed. Due to the design, it is not easily fixed and cost an outrageous amount of money to fix for a vehicle with less than 100,000 miles. This is a safety risk because if this is a common issue, which it is, and the engine fails while driving it, the driver is not able to get to a safe area to address damages and is left stranded. There are numerous complaints regarding the design flaw of having the water pump inside the engine. The manufacturer refuses to address the flaw. The check engine light came on and was taken in and wrongly diagnosed...

I believe I am getting the Cam Phaser Rattle sound in my 2018 Ford Explorer Platinum with the 3.5L EcoBoost Engine. Through research I have seen that this is a common problem among other 3.5L EcoBoost Engines like the F-150, Expedition, and Navigator. This happens at Cold Start ups I noticed. I have tried calling my dealership and Ford Corporate about this issue and they say that they can't cover this at all. My vehicle is at 65k miles (just outside the warranty).

Engine light turning off and on. Engine overheating light on. Told by Ford dealership that I need engine replacement.

I am writing to formally report a significant mechanical issue involving the water pump in my 2018 Ford Explorer with the 3.5L V6 engine. This vehicle recently experienced a sudden failure of the internal water pump, a problem I have since learned is common across this model and others using the same engine design. In my case, the water pump failure occurred just outside of the vehicle’s extended warranty coverage, leading to engine overheating and a substantial repair cost. What makes this issue particularly concerning is the design flaw in which the water pump is located internally, driven by the timing chain. When the pump fails, it can leak coolant internally, potentially leading to catastrophic engine failure without warning. This design not only makes the part extremely costly to repair (often $2,000–$4,000 or more), but it also introduces a serious safety risk—drivers may experience engine overheating or seizure while on...

On Thursday, June 14, 2025, the check engine light illuminated on my 2018 Ford Explorer, which has fewer than 75,000 miles. I promptly contacted my trusted local mechanic, Bananno Automotive, to schedule an oil change and requested that they also inspect and diagnose the cause of the warning light. During their inspection, they performed a diagnostic scan and identified stored engine code P0430 – Catalyst System Efficiency Below Threshold (Bank 2), which corresponds to the catalytic converter on the left side of the radiator. Concerned that delaying the repair could lead to increased emissions and potential damage to the engine, I authorized the necessary repairs. All work was completed by June 23, 2025. It was only after the repairs were finalized that I reviewed the Ford Warranty Guide and discovered that this issue is, in fact, covered under warranty. Unfortunately, Ford has denied reimbursement solely because the repairs were not...

The water pump failed. It is internal in the engine. Not sure yet if coolant got into the motor. It is not safe to drive the vehicle and have to get it towed for this expensive repair. Water pumps should not fail at the rate they do on the ford 3.5 motors. They need to have a recall on them.

The contact owns a 2018 Ford Explorer. The contact stated that while driving approximately 35 MPH, the vehicle started vibrating excessively and the vehicle hesitated with several unknown warning lights illuminated. The contact stated that while driving uphill the message "Hill Start Assist Not Available" was displayed. The contact was able to drive uphill; however, the failure recurred after driving a short distance. The transmission unexpectedly downshifted and the vehicle was not able to pull into the driveway. The contact stated that several unknown warning lights were illuminated. The vehicle was towed to the local dealer, who diagnosed that there were metal shards found in the engine and that the transmission had failed. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 86,000.

The High-Speed Cooling Fan Motor Relay (Recall 21N01) and the Exterior A-Pillar Apical Molding (Recall 24V031) failed on my vehicle. The cooling fan caused the engine to overheat repeatedly, and the vehicle became undrivable. Unfortunately, I no longer have the vehicle, as it was surrendered to my bank and later sold at auction. However, service records, diagnostic reports, and recall information are available upon request. The overheating engine presented a significant safety risk while driving, as it could have caused the vehicle to stall or catch fire. A AAA roadside technician confirmed that the vehicle was unsafe to drive due to the overheating issue. This defect left me stranded, requiring alternative transportation and creating a hazard for others on the road had I continued driving the vehicle. Yes, the problem was confirmed by a AAA roadside technician, who performed a diagnostic scan and identified that the engine overheating was due...

My 2018 Ford Explorer rolled backwards down a hill while in park and engine off.

We took the car in for the recall 24V031 which is not able to be fixed at this time due to lack of parts. The Ford dealership explained to us that there were 2 other recalls on this vehicle that had not been addressed. They asked us if we wanted them fixed. We agreed to have them fixed. One being the luggage rack clips the other being high speed fan motor relay switch. The luggage rack was completed. The dealership replaced the fan not the relay switch as the recall indicated. When we brought the vehile home, the fan was super loud and would come on when ever it wanted too, whether the vehicle was running or shut off. It would also runn continuously even though it was not hot out nor had the car been running. We took the car back to the dealership. They looked into it. Ordered...

The vehicle experienced multiple defects, including: Overheating due to a malfunctioning cooling fan motor relay. Exterior A-pillar trim detachment. Persistent starting issues, even after replacing the battery. The vehicle is no longer in my possession due to repossession, so inspection may not be possible. How was your safety or the safety of others put at risk? The overheating issue posed a risk of engine failure while driving. The detached A-pillar trim could have caused a road hazard for other drivers if it fell off while in motion. The starting issues left me stranded on multiple occasions, which could have been dangerous in certain environments. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the dealership confirmed the issues but stated the vehicle needed to meet specific conditions (e.g., 100 miles for certain repairs) and required costly repairs that I couldn’t afford. Has the vehicle...

This will be another submission as I am getting frustrated. My Explorer has had constant issues like clock work every 6/7 months. I have gone through 6 batteries in a two year time span. I have had the battery control module replaced because I thought that would be the fix. However it is not. While operating my vehicle yesterday on [XXX] after barely even starting the battery died and my car said multiple systems were failing almost causing someone to rear ended me. This is a safety issue like no other. When will I receive feedback for these matters I keep submitting? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Failed water pump and coolant leak. Numerous vehicles are failed for the same reason at each local shop and Ford dealer we’ve contacted for a quote. Repair costs are expected between $5,000 and $6,000.

Unknown Multiple owners of 2018 Ford Explorers are reporting oil leaks from bad seals. The oil leaks can cause fires, so we are in the process of having our Ford repaired at a mechanic and will know more at a later date.

My car has 105k miles on it. And the check engine light came on. Code was 3rd cyl. Misfire. Changed spark plug and coil pack. Light cane back on the next day. Then the overheat warning comes on. Shut vehicle off to cool. The coolant is now completely empty. Vehicle will not start. Have towed and the dealership gets it yo start but smoking. Dealership basically doesn't even notice that the fluid is low after we had filled it again. They say there's nothing wrong even though it wouldn't start and then was smoking when it did. Take to another mechanic to discover coolant in the 3rd Cylinder and need a whole new motor. This issue has been common in these ecoboosts! But Ford has still failed to recall or do anything about it. Can cause overheating and fire from what I've read. And also cracked head and or block!...

Took the vehicle to a Ford Dealership to fix the roof railings (recalled). While doing their inspection they said the vehicle was out of coolant and that the water pump needed to be replaced and it would cost $4400.82. There were no warning lights or anything indicating that anything was wrong with the vehicle. This is a safety issue because the vehicle could overheat and shut down in the middle of the interstate without any warnings. This is a problem with the Explorer and should be remedied. Ford said there is a possibility that the coolant leaked into the engine and if so, a new engine would be required.

Doesn’t want to run right

Driving home from work when all of a sudden my car started jerking, not shifting correctly and could hear a noticeable noise coming from the engine. Low oil pressure light came on and pulled over. Car would not restart. Had it towed to mechanic and was determined that the engine was hydrolocked due to coolant getting into the pistons and oil. New engine needed on a 6 year old car with 91,000 miles. Upon researching it seems this is a common problem with eco boost engines and I don’t believe I should be responsible for this apparent COMMON issue.

The contact owns a 2018 Ford Explorer. The contact stated that while driving at an undisclosed speed, the check engine and coolant warning lights illuminated. The vehicle was taken to a local independent mechanic where it was diagnosed that the water pump had leaked into the engine and advised the contact to maintain the anti-freeze level at full. The vehicle was taken to another local independent mechanic for a second opinion where it was diagnosed with the same failures and advised the contact to reach out to the local dealer for assistance. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 160,000.

The contact owns a 2018 Ford Explorer. The contact's wife stated that while driving at an undisclosed speed, the vehicle stalled with the low oil warning light illuminated. The vehicle was towed to an independent mechanic where it was diagnosed that the engine failed and needed to be replaced. The vehicle was not repaired. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure and referred the contact to the NHSTA Hotline for assistance. The approximate failure mileage was 125,787.

My check engine light came on took the SUV to Ford Dealership for service. They informed me that my engine had coolant intrusion and that I would need a new engine. In reviewing this information online I noticed that there have been multiple recalls on the EcoBoost engine with the same problem.

My 2.7L eco boost ford explorer had a crack in the intake manifold allowing water to leak into the piston heads. This resulted in engine misfire and ultimately led to a full engine replacement. The service technicians at the dealership noted that the 2.7 L eco boost are notorious for cracked engine components due to a mismatch in metal alloy. In reference to NHTSA# EA23002.

I purchased this vehicle Nov. 2021 with 46,000 miles and still having warranty on it. After driving less than 3000 miles began to see large/heavy amounts of blue smoke coming from the exhaust when starting the vehicle along with random loud noise at certain times when starting. Checked the oil and it was almost 2 quarts low and oil life said only 33% left. Complained that I thought it was burning oil at the dealership and their fix was to give me a free oil change and a new air filter saying there was no problem. I continued to have these same issues over the next 2 years with no documentation by the dealership of my complaints and no solution to the continued problems. At 1 point it was over 3 qrt. low on oil with none on the ground. Then on 3- 31-24 while headed for vacation and over...

Check engine light showing. Diagnostic testing shows misfire in cylinder #3. Ford dealership ran diagnostic testing ($169.95) and verified concern and found coolant intrusion cylinder #3. Advised, due to mileage (75,976 miles), replacement of long block. Replacement cost estimated at $11k. No repairs have been performed at this point due to excessive cost. Second Diagnostic test ($89.95) with independent mechanic - confirmed original verification and found evidence of wear on long block. Mechanic stated that he currently had a Ford Edge in the shop with the same issues. There is currently a class action law suit against Ford for same the issue..

Our 2018 Ecoboost Ford Explorer started releasing smoke from the tailpipe when starting in April 2023. I took it in to the Ford of Kirkland dealership in early May 2023. They kept my car for 9 weeks, and then said there is nothing wrong with it and gave it back in July 2023. The car kept having the same issue. This was while it was still under warranty about 96,000 miles. Fast forward to February 2024, the car has continued to smoke this entire time since the dealership gave it back in July. In February, I was driving home on the freeway going up hill when the car suddenly decelerated rapidly. I was able to get off the freeway and have my husband come and he got it home. We contacted the dealership (Ford of Kirkland) the same one that did nothing in 2023. They trailered it in for a...

The contact owns a 2018 Ford Explorer. The contact started while driving at approximately 20 MPH, the check engine warning light and several unknown warning lights were illuminated. The electrical system shut down and the engine stalled. The instrument panel became inoperable. Additionally, the power steering became inoperable and the brake pedal was depressed, but failed to respond, causing the contact to lose control of the vehicle. The vehicle drove off the road and violently crashed into a ditch. The air bags failed to deploy. The contact sustained a significant whiplash and a stiff neck. The contact had not yet received medical assistance. The contact was able to exit the vehicle through the front driver's side door. The vehicle was towed to the contact's residence. There was no police report filed. The contact stated that the front passenger's side and the front undercarriage of the vehicle were significantly damaged. Additionally,...

Failed water pump/coolant leak. Vehicle will suddenly overheat and engine can seize. Vehicle will stop unexpectedly and endanger the lives of the driver, passenger and other motorists. Temperature warning and check engine light comes on only when vehicle is overheated at which point there is no coolant left. Issue has been confirmed by an independent service center. I was told that they would not touch this repair and to take it to a dealership due to the location of the water pump, it's relationship to the timing chains and the labor intensive job. The part is inexpensive. A simple Google search indicates that this is a known design problem since approximately 2011 and affects many makes and models. There are several class action law suits and a recall was issued in Canada for the same issue. Ford will acknowledge "off the books" that it is a problem but offer no...

Ford EcoBoost 2.0 engine failure at 66,000 miles as coolant has leaked into the engine compartment and oil pan. Known issue by Ford as design defect on the EcoBoost engines. Current class action lawsuit over this [XXX] et al., v. Ford Motor Company, Case No. [XXX], filed in the United States District Court for the District of Delaware. Plaintiffs have experienced the exact same failures on the EcoBoost engines. Ford issued multiple technical service bulletins (TSBs) and other service messages for vehicles equipped with EcoBoost engines. Luckily, the failure occurred at home and not while driving at highway speeds as there have been reports of fires occurring if vehicle is moving during failure. Vehicle began rough idling 7-10 days ago and check engine light showed a code for misfire of cylinder. Had plugs changed but check engine light returned and then as of today, after overheating light came on dash...

Water pump failed. Coolant is leaking

Three times within the last 4 years I have had a Map Sensor failure. I was told the first time, this is rare. I was told the second time, this never happens twice. This time I'm told that they just don't know what is causing it. Must be 3 bad sensors in a row somehow. The engine failure on [XXX] was nearly catastrophic and I nearly died. I was going 70mph on a [XXX] at [XXX]. [XXX] can be dangerous under the best conditions, this was during dangerous storms along with being at rush hour. The engine completely stalls and I lose all power to drive. The first time it happened in a parking lot in August of 2020. The second time was Sept of 2022 and I was in my neighborhood. Sunset Ford has no explanation and have repaired it and sent me on my way once again. There...

On February 9, 2024 I was headed to work as a ICU Charge Nurse. I was driving about 65 mph on the highway and suddenly my engine failed. My engine completely turned off. I wasn’t able to press the gas to accelerate. My steering wheel also locked so I had no control over my vehicle anymore. Eventually, smoke started to come from my engine. I nearly lost my life with no control over my vehicle. Someone could have hit me from the spontaneous failure of the engine. This was extremely traumatic for me. I bought this car from a Ford dealership and get all my services done through Ford. On January 24, 2024 I took my car to Ford for a multi-point inspection, oil change, and tire rotation. I also got a fuel system change. I had no warning lamps, messages, or any symptoms that the vehicle would fail prior...

Torque converter issues as outlined here: [XXX] Almost was in accident due to loss of power and slow take off from issue with transmission torque converter. Engine shaking bad when in drive or reverse while stopped. Caused two motor mounts to be damaged. One split open and leaked fluid. Those have already been replaced. Less than 60k miles this should not be an issue. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I purchased this used vehicle from Carmax 1/2022. Prior to my purchase it was a fleet vehicle. On 09/18/2023 I experienced EcoBoost engine failure.Mileage is currently roughly 49k. Incident occured 2 months outside of Powertrain warranty. The engine light would come on intermittently when driving. Took the car for a diagnostic to diagnose issue and had #3 ignition coil replaced due to misfire message. Few days later, light would come back on. After 3rd time of me going back and forth to the repair shop because of the light coming back on and vehicle drive not being as smooth as it usually is, I took the car to Ford dealer service center, where I was advised that this is a known issue, but no recall has been issued at this time. In addition, I was told that this engine is on back order and will not ship out until March...
