2016 FORD EXPLORER Engine Problems

While driving the crankcase sensor malfunctioned and caused my vehicle to stall without warning, this is a safety issue because of you are driving at highway speeds this will prevent the vehicle from being controlled properly to get to the side of the road. This sensor does not give any engine codes suggesting that it needs replaced until it goes out completely. The check engine light did not come on until after the component failed. I ordered a new part directly through Ford and even they said "yes that part will go out without any warning at all and will shut the engine down completely". When this sensor went out, it also caused pressure to build up in the engine which in turn has led to several other components that now need to be replaced. I have a had a mechanic look at it, and it now requires a turbo...

Coolant intrusion in the cylinder walls

Torque converter issue causes shuddered, can cause driver to unexpectedly adjust speed rapidly.

Good Morning, I’m reaching out in regards to my 2016 Ford Explorer. I’ve been trying to get the necessary recall repairs completed, but unfortunately, I’ve been unable to locate the required pillars for the repairs. I recently brought my vehicle back to the dealership, but was told that no work can be done until both parts are available. I was also advised to try sourcing one of the parts from another Ford dealership on my own, which I’ve had no luck with. To be honest, I’m feeling very overwhelmed. I purchased this vehicle used, back in September 2025, and since then, it has been one issue after another. I’ve already invested more into mechanical repairs than what I currently owe on the vehicle. I’m a [XXX], and this vehicle is our only mode of transportation. I’m growing increasingly concerned for our safety, especially knowing that the recall parts are critical...

I’ve had it twice be an issue where the engine didn’t run quite right. The first time I took it to the mechanic it was determined the timing chain was bad and they also said this is a well known issue with the ecoboost engines in these explorers. Only about a year later after replacing that and the water pump I went to start the explorer and it wouldn’t start. Took it to the mechanic again and they found that the timing chain, again, had failed and this time it also caused damage to a piston rod. They said they were surprised it wasn’t catastrophic damage to the engine because of this. I’ve now had to spend literally thousands of dollars on this vehicle for timing chain related issues alone in just over 3 years of owning it. Searching online finds unending reports of similar issues to this as well...

Took the family SUV in for a standard oil change and 100k service to Ford dealership. Upon performing a coolant flush, the water pump began leaking. It was found that the internal water pump was leaking and needed to be replaced along with the primary timing chain and tensioner items. There were no warning lamps or indicators to let us know this was an issue. The dealer service center replaced the internal water pump, refilled system and test drove. It was re inspected and leak has been corrected. However, this cost us $4, 366.80 for an issue Ford knows is a reoccurring issue in this model of SUV and a huge hazard for families.

Engine stalls out when accelerating, coolant is leaking into the motor. Got it checked out my mechanic, needs new engine due to improper manufacturing issue

Water pump

My vehicles wrench sign would turn on do a little jerk then I would lose power to my car. Showed malfunction to power train. Took it to mechanic said there was a Crack in the valve gasket and they fixed that and changed spark plugs. A month later car did the same thing. Has done it a total for 4 times very scary when on a high way and it does it and I have to pull over with traffic coming. Took it to another mechanic and he couldn't figure it out either because there are no codes but said he seem something similar and I needed to change all my coils. So I did that. Thousands of dollars later and no one can still figure out the problem. I don't know if it's some safety issue with the engine or transmission. But 3 certified mechanics can not figure out...

2nd time in two years I have to fix the water pump

At around 50,000 miles the Turbo on the engine was leaking oil. Dealer replaced the turbo and kept the part. It needed to be replaced to avoid a catastrophic failure of the turbo which in turn could cause severe engine oil loss resulting in engine failure and oil contamination of the catalytic converters O2 sensors and possibly a car fire. There was no warning but was caught during a routine oil change. Unknown if the dealer reported it.

A engine getting hot light came on in our Explorer and we checked the coolant levels and most of the coolant had leaked out. We filled the coolant but the check engine light was still on.A mechanic did a thorough assessment and found 3 codes were being thrown. He discovered that the coolant was leaking into the combustion chamber. After much research online, we found that there was a class action lawsuit on other ecoboost Ford engines that had the same issue. Out particular Model was not included, but it was the same safety issue. The engine could become overheated and start on fire or the engine could fail and seize up while driving. We personally experienced a few times where the engine would hesitate and almost not go forward but we thought it was a spark plug issue. It was a little scary while driving in traffic and could...

The contact owns a 2016 Ford Explorer. The contact stated that while driving at various speeds, the check engine warning light illuminated, and the vehicle failed to properly accelerate while depressing the accelerator pedal. The vehicle was taken to the local mechanic who diagnosed that oil from the turbo booster had leaked onto the catalytic converter and both the turbo booster and catalytic converter needed to be replaced. The vehicle was not yet repaired. The contact indicated that previously the power transfer off unit was faulty, causing the vehicle to suddenly lose accelerating power; and the front control arms and ball joints were replaced. The manufacturer and local dealer were notified of the failure, but no assistance was offered. The failure mileage was 85,000.

The contact owns a 2016 Ford Explorer. The contact stated while driving at an undisclosed speed, there was steam was coming from under the hood. There was an abnormal odor entering into the cabin of the vehicle. The check temperature warning light was illuminated. The contact attempted to refill the coolant; however, the failure reoccurred, and the vehicle was towed. The local dealer was contacted and advised the contact that the water pump might need to be replaced. The vehicle was not diagnosed or repaired due to the cost. The manufacturer was made aware of the failure. The failure mileage was approximately 100,000.

The water pump failed vehicle only has around 105,225 miles on it. This has been a known issue with the 3.5L Twin turbo ecoboost. The water and coolant continuously coming out happens to be on the alternator which has caused it to short out and no longer be working properly. There has not been any kind of malfunction or warning lights for any of the issues and because of the way ford designed the water pump to be inside the motor working off the timing chain it turns into what the book lists at 14-15 hours to complete. The motor has to come out taken apart to replace the water pump and with that not just one but both timing chains have to be set again which adds additional hours for the repair and of course more money to take it to a ford shop to have it fixed the...

Water pump failure, like many others. Caused engine to overheat, lose AC. Issue caught before complete engine failure. INTERNAL WATER PUMP CAN GO OUT AT HIGHWAY SPEEDS CAUSING THE ENGINE TO SUDDENLY LOSE POWER AND SHUT DOWN SUDDENLY CAUSING THE POWER BRAKES AND POWER STEERING TO FAIL ALL AT ONCE AND LEAD TO LOSS OF VEHICLE CONTROL WHICH IN TRAFFIC COULD CAUSE A FATAL ACCIDENT WHILE THE DRIVER STRUGGLES TO MAINTAIN CONTROL WHILE ATTEMPTING TO MOVE TO THE ROADSIDE OR EMERGENCY LANE . WHILE FORD HAS KNOWN OF THIS FLAW IN THE ENGINE DESIGN FOR YEARS AND DID NOTHING TO RESOLVE THIS ISSUE.

The water pump failed on my way home from work. A light in my vehicle started blinking rapidly and a warning alarm started sounding in the vehicle cabin unexpectedly. My vehicle suddenly overheated in the middle of a busy intersection causing me to stop unexpectedly to assess the situation before proceeding to safety. I (middle aged female) had returned from a long trip with two toddlers 800 miles round trip which extended late into the night on remote stretches of road without assistance available for several miles only a few days earlier. Had this happened a few days earlier, during that trip, I would have been stranded with two toddlers, alone after dark in a remote location. An independent service center made the diagnosis and performed a repair. They stated I was lucky the leak did not enter my oil reservoir based on the location of the water pump, locking...

The contact owns a 2016 Ford Explorer. The contact stated while driving at an undisclosed speed, the vehicle lost motive power and was not able to exceed 50 MPH. The contact stated that the check engine warning light had been illuminated for over 3 years. t uThe vehicle was taken to a dealer to be diagnosed and the contact was informed the engine needed to be replaced due to the rear turbo causing damages to the front turbo and the engine.

The manufacturer was made aware of the failure; however; the contact was informed that the vehicle was nonder recall and that the vehicle was out of warranty. The failure mileage was approximately 97,000.

The water pump failed causing all loss of antifreeze. After doing extensive research, this is a known issue and ford refuses to fix the issue. To fix the issue a large part of the engine has to be torn down to access the water pump.

The contact owns a 2016 Ford Explorer. The contact stated while attempting to start the vehicle, the vehicle sputtered with the check engine warning light illuminated.

water pump failure at 60K miles on a 2016 ford explorer, this model has the most reported water pump failures on record. this is a 15 hour repair job at the dealer, and the same complaint litters the internet. The failure on my vehicle was confirmed by dealer, $4k to fix. Not to mention the mess in my driveway where the coolant expelled without notice. If I drive it, the engine will be damaged, and there goes my car. In 2020 NY and MI class action lawsuits over this issue were settled & closed WITH payment to plaintiffs, yet no recall. WHY? too expensive for Ford? We see safety recall on clips yet nothing on an admitted engine problem than causes stalling or engine damage while running? There's a class action in Canada. Ford is dodging a known defect. Please do something about this.

The power transfer unit is broken. Symptoms are vehicle shuddering, vehicle sounds like it is going to stall. This could cause a major accident at any moment.

My car has 84000 miles on it. The car recently over heated, I checked the coolant level, and it was low. I filled it to the required level and the warning went away. 2 weeks later it came back, I brought it to the mechanic and was told that the engine needs to be replaced. That it is recycling exhaust from the engine back through the coolant system and that cylinder 3 is misfiring. I spent over an hour on the phone with Ford who repeatedly stiff armed me on any sort of assistance with the issue or information on expected or estimated failure rates for these issues. The car is currently at the mechanic where I have an estimate with a $12,000 price tag on it. To make this worse, in October of last year I was driving down [XXX] and when I went to exit the highway, there...

Vehicle: 2016 Ford Explorer Sport Mileage: 93,000 Complaint: I am reporting recurring turbocharger failures in my 2016 Ford Explorer Sport. The first failure occurred at 50,000 miles and was covered under warranty. The vehicle is now experiencing the same issue at 93,000 miles. Ford Customer Service has denied assistance, and a Ford dealership quoted a $5,500 repair cost. I believe this premature and repeated turbocharger failure suggests a possible design flaw in the 2016 Ford Explorer Sport's EcoBoost engine. This issue has caused significant financial hardship and raises safety concerns. Request: I urge the NHTSA to investigate potential design defects with the turbocharger system in 2016 Ford Explorer Sport models. I also request that the NHTSA review Ford's handling of customer complaints regarding this issue.

The contact owns a 2016 Ford Explorer. The contact stated that the check engine warning light was illuminated, and the vehicle was stalling because oil was leaking onto the crank case-control sensor.

The vehicle was not repaired. The manufacturer was made aware of the failure and a case was opened. The failure mileage was approximately 125,900.

The contact owns a 2016 Ford Explorer. The contact stated while driving at various speeds, the vehicle failed to properly accelerate.

The manufacturer was notified of the failure, but no assistance was offered. The local dealer was not yet contacted. The failure mileage was 137,000.

The at the engine is built the coolest is leaking into it. This causes the engine to seize while driving and is very dangerous. If you catch it early it’s an expensive fix if you catch it late it’s a new engine you’ll need/ there is no warning signs for it.

Driving on [XXX] when the engine began smoking (fogging) and I was unable to see. I stopped and could not go any further. Two cars nearly hit me. It took 10 minutes or longer for the car to cool down and the computer to allow me to move the vehicle 20' to get off the busiest street in Alabama. The car has 106,000 miles on it and the Ecoboost engine is blown. Ford refuses to do anything about it. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2016 Ford Explorer. The contact stated that while driving at approximately 10 MPH, there was a burnt hydraulic fluid odor inside the vehicle when the vehicle shuddered and stalled. No warning light was illuminated. The vehicle was taken to an independent mechanic and was diagnosed, and the engine mount was replaced. The failure recurred; however, there was a rotten, sulfur like odor coming from the vehicle. The vehicle was not taken to the dealer or repaired. The manufacturer was contacted. The failure mileage was unknown.

In August 2023, my vehicle began to make a popping noise and began to lose power when attempting to accelerate. It was diagnosed by the repair shop as a turbo going bad. I repaired the turbo. In December 2023, the check engine light came on. The repair shop indicated that the lifters and cam shafts were bad and caused scoring to the engine block, requiring the engine to be replaced. The repair shop asked if I had been changing the oil regularly. I indicated that I did change the oil per when the vehicle would notify me it was time. The repair shop noted that I changed the oil every 10k miles. Per the repair shop, not changing the oil regularly (because the Ford vehicle system designed to tell me when to change the oil) ultimately caused me to need to replace the turbo and the engine. All because the...

The contact owns a 2016 Ford Explorer. The contact stated that while driving at undisclosed speeds, the steering wheel was making an abnormal grinding sound. The ABS, air bags, and check engine warning lights were illuminated. The contact called the local dealer and was informed that the parts were not available to repair the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was contacted, but no assistance was provided. The approximate failure mileage was 14,000.

The explorer started having issues with the heater not working when stopped. After some research it recommended that we check the coolant level. The coolant was low. Then we refilled it and then it happened again 3 weeks later and the coolant was low. This made us believe there was a coolant leak. After removing the bottom cover under the car it was saturated with coolant with drops coming from various areas on the passenger side. We took it to a mechanic and then transferred to a dealer and both confirmed it was the water pump. Ford negligently designed the water pump within the engine with the timing chain. If enough of the coolant mixes with oil it will cause the engine to seize and the car to shut off. I have two little kids that are in the car with me. This negligent placement can lead to cars seizing...

The water pump failed causing coolant to leak into the oil pan causing my vehicle to die suddenly and without any warning lights or messages on a high speed, heavy traffic metropolitan interstate/highway (35W in Minneapolis). I was commuting home from work. It was completely dark. I was in the far left lane and had to quickly maneuver across 4 lanes to the right shoulder narrowly missing being slammed into by other cars before the vehicle completely died. I waited for a towing service in the dark while other vehicles including semis sped extremely close to my vehicle with only my hazards to warn them I was there. Vehicle was towed to a local repair shop and they confirmed the water pump failed and coolant leaked into the oil, ruining the engine. I've been researching online and am reading that this is a very common and known issue with lawsuits....

My engine sounded strange at startup in the mornings so I asked the ford dealer to look at it because Firestone could not find anything wrong with it and I had two recalls needing addressed. I took it to the dealership in diberville, MS first and scheduled the current recalls to be fixed. I was told my engine needs to be replaced because there is evidence of coolant in the cylinder head causing a random misfire but couldn’t tell me if that was it for sure without breaking down the engine to diagnosis properly. I bought an extended warranty policy incase there was an issue in the future. I was actually told by one dealer to “clear the code and trade it in immediately or wait till the engine blows up”. They didn’t even fix the recall because they had to order the parts… The same problem kept happening randomly...

Water pump went out and water and oil mixed started smoking and loss of power then engine just shut off now wont turn over

in 2021 my check engine light came on. My Vehicle was just 5 years old, but 14K miles out of the manufacture warranty. My Engine failed and I had pay out of pocket to get another one. It's all documented by my mechanic and in Ford's system. I know there is an investigation of a possible recall for the engine failures and FORD is saying one is not needed because all the engines were fixed under warranty. Well, mine was not. My vehicle hardly drove and had no power. I had to come out of the pocket $6,000 dollars and at the time Ford would not cover it or help in any way financially. I believe the #4 in the engine failed. Coming up with the money was very difficult and I am still paying the engine cost off on top of my car note.

Coolant (water) pump leak, leading to replacement or eventual failure. As the pump is located internally of the engine, the effort to repair is quite extensive. This is a known issue for this engine, with previous versions under a recall. The pump location was relocated externally of the engine in future designs, further evidence of the knowledge of the issue.

Water pump leaking and needs to be replaced. Can cause engine failure and lead to being stranded on highway. Multiple forums have people with the same issue. No warning lights have come on. I took the vehicle in for another issue and they pointed out the leak to me.

1. Component: Electronic throttle body 2. Our vehicle shut down (limp home mode) on the Interstate traveling at high speeds. We narrowly avoided catastrophic accident with other vehicles on the road. 3. The problem was confirmed at the dealership where it is currently being replaced at our expense of roughly $1,000.00 4. Only inspected by dealership (Crain ford little rock, ar) 5. No warning until the part failed. We received airbag light and service light during shut down on the interstate. I have called ford pleading with them for some assistance with this large bill, which is hard to deal with right before Christmas with 2 children. I was told that my VIN# was not effected even after ford posted a notice for 2016 ford explorers Electronic Throttle Body replacement. Ford customer service ended our call after stating that nothing can be done due to this not being a recall...

Water pump failure, engine coolant leakage from water pump

Last night check engine light turned on. I called the dealer to get an appointment first thing next morning to get it checked. In next 2 minutes engine coolant over temperature sign turned on. i got scared and stopped the car immediately and got it towed to the dealer right away. got a call from the dealer saying that the engine blew up and needs to be replaced. to my question how this could be the case for the engine to blow up within 2 ninutes of the furst check engine sign turning on, i was told by the dealer representative that the engine damage was done before even warning lights got on. This is unacceptable and extremely dangerous! Car failed to provide proper warnings which caused very dangerous to the safety and ireversable damage to the car.

My check engine light came on and began blinking. I had the car towed to a local shop to avoid any additional damage to the engine. The shop determined the car had significantly overheated due to a faulty water pump and the engine would have to be replaced. Leading up to this my check engine light never came on and the temperature gauge never spiked; there was no indication it was over heating. After being quoted $9k to replace the engine, I called the dealership looking for help. They are aware of the extensive issues I’ve had with my vehicle but were unable to help me because I’m over 100k miles (I opted for the extended service plan) and suggested I call the Ford Customer Service line in hopes they could assist. I was denied a claim due to my mileage and instructed to write a letter to the Ford...
