When accelerating and braking, motor rocks forward and backwards. Rpms jump erratically when this happens and when sitting stationary at a light or stop sign. Which causes the entire vehicle to vibrate. Oddly enough, fuel injector cleaner seems to help with the vehicle shaking somewhat.

1. Component/System Failure: The water pump on my 2016 Ford Explorer failed, causing a significant antifreeze leak. The component is available for inspection upon request. 2. Safety Risk: The failure creates a risk of engine seizure while driving. Loss of engine coolant can cause the engine to overheat suddenly, potentially leading to a dangerous situation on the road that could harm myself or other drivers. 3. Confirmation of Problem: The problem has been confirmed by the dealer service department during inspection. The water pump leak was observed and diagnosed by a certified Ford service technician. 4. Inspections: The vehicle has been inspected by the dealer. I have also documented prior repairs to the vehicle, including a timing chain replacement two years ago. The water pump issue has not yet been inspected by Ford corporate. 5. Warning Lamps/Symptoms: Prior to the failure, there were no warning lamps on the dashboard. I...

The factory installed headlight screw punctured the coolant line of my 2015 Ford Explorer causing my transmission to stop working properly. This resulted in a $725 tow bill and $1,067.56 in repairs. The certified mechanic verified that the screw was an original part and it punctured the line, likely after some time rubbing against it. The transmission did not appear to be damaged however my safety was at risk trying to pull over to when the vehicle would no longer shift gears. I have a video of the leak that lines up with the screw placement but was not able to upload it...I am happy to email it to you.

When vehicle is on and either in park or at a stop, RPMs will idle at about 800-1000 RPM then randomly shoot up between 2000-2500 RPMs then drop to below 500 RPMs before returning to idle. It’ll do this randomly.

Took vehicle in to see local mechanic due to small drops of antifreeze on ground. Mechanic concluded water pump would need to be replaced. Since water pump is built into the engine for this Ford model, the engine would need to be dismantled to fix.

i dont understand ford explorer has same recall i have a lot of recall on these and i cant take it off everytime its a recall. i work 7 days a week. Thats the reason i try to trade it in . But i still own a lot for it. I dont know to much about the explorer i brought from the carlot.

Car kept overheating and I checked the antifreeze. Several times during the week it was empty. Took it to PepBoys and found out the water pump was faulty.

Sudden Unintended Acceleration of the vehicle when slowing to park vehicle. This has happened on 2 occasions- both scenarios the same: slowing and turning left into a parking space, foot on the brake, almost to a complete stop and the vehicle suddenly accelerates out of control. the 1st time into a tree, the 2nd time into a parked/unoccupied vehicle. The brake was applied w/o response, the vehicle would not stop. I am certain my foot was not on the gas. Fortunate no one was injured.

Water pump and timing belt failure, causing overheating and leaving driver stranded and posing threat for engine failure.

Water pump inside the engine went out and was leaking coolant all over the engine and transmission. Caused the engine to over heat and the cabin heat to fail. Risk of fire with fluids on engine. Problem so common there is a class action lawsuit but no recall.

Premature water pump failure on 2015 Ford Explorer Limited with 51,000 miles. Noticed coolant leak while changing oil. Took it to a mechanic that pressure tested cooling system to discover water pump is leaking.

While driving at 40 mph the car suddenly lost power. The accelerator would not respond. We were luckily able to coast downhill and get on the shoulder. This has happened four times in six months. The car is not safe for highway driving.

Leaking water pump

Turbocharger oil supply tubes leaking onto exhaust manifold Same engine as the recalled 2016-2017 Models

Last year the water pump needed to be replaced at 99,500 miles. It cost upwards of $2,000 to be replaced. Fast forward now, a year later the check engine light is on, the car is not accelerating properly and it is back in the shop. The shop called and said it is not as simple as fixing the sensors. They have to look further and thinks it may be the timing chain which would be another $2,000. When it was in the shop a year ago fixing the water pump they said the timing chain at that time looked good. I am so frustrated that the water pump is not a part of a recall since our shop said they are seeing this all the time with Explorers with about 100,000 miles.

My 2015 ford explorer water pump has failed sending coolant all over. The water pump in an internal component of the engine. I am lucky that I caught the water pump failure when I did and it didn’t completely catastrophically fail. There are numerous reports that the water pumps catastrophically fail and send coolant and metal particles into the motor causing it to also catastrophically fail. If my engine failed while driving on the highway I could have been seriously injured or killed or worse I could have seriously hurt or killed somebody else. I brought my car to ford 7/21/23 where they did general diagnostic tests everything was negative and nothing was found and I was sent on my way. On 7/29/23 I noticed I had a puddle in my driveway and there was definitely a leak I brought my car back to ford where they spent an entire...

I have a 2015 Ford Explorer. I have had it inspected by a mechanic at the dealership where I purchased said vehicle. I also have taken it to Ford dealership in my town. My car runs perfectly fine then it doesn’t. I have been stranded numerous times and I have replaced the battery in the smart key as they said that would be the problem. I have had the computer reset to my car. When it happened last my camera to help me back up stopped and I was almost in a very bad wreck with my children and grandchildren in my car. It just died!!! I am now sitting in a parking lot at 93 degrees and it again won’t start and know one knows why. I have done everything I can and have been told. I don’t hot rod in my vehicle. Someone for the love of god...

3/23 I noticed my coolant reservoir was empty. The vehicle was involved in a minor accident in 12/22 and so I thought coolant slowly leaked out due to the accident. The vehicle was repaired at a collision center so I was concerned they didn't repair or totally missed the leak. I filled it up and took the Explorer for an oil change and that is when the mechanic informed me that I had a small coolant leak. I contacted the collision center and my insurance and both were stating that was from wear and tear. They also proceeded to tell me that is a big issue with the Explorers and certain other vehicles. They mentioned a lawsuit was filed in MA because of this issue. The leak start to get worse, causing me to constantly refill the reservoir with coolant. Always had to have coolant in the vehicle because you...

The contact owns a 2015 Ford Explorer. The contact stated that while driving at an undisclosed speed, the vehicle made an abnormal sound. Additionally, the contact stated that while the vehicle was idling, the vehicle was shuddering.

I have a recall on rear suspension I have called to have the repairs done several times I was given response of they didn't have the parts needed and would take several weeks . Rear suspension is very unsafe and now the engine cooling component is causing issues with over heating and not giving any warning lights on dash and am afraid found cause fire or some unsafe issue

While driving the temp started to fluctuate, causing the car the shut down in traffic. I had no clue what was happening. The only warning I got from the vehicle was a check engine light. This should not be possible. I understand the design is meant to protect the engine, but what about the driver. This was horrible and I've seen hundreds of others with this same issue. This needs to be recalled. In addition, it will cost me 4000 to fix this...while the pump itself only costs 200. The labor is the other 3800. This is a horrible thing to do to drivers.

Waterpump

Water pump died at 80,000 miles. Seems in my research this is a common probably with class action lawsuits

The contact owns a 2015 Ford Explorer. The contact stated that while driving at an undisclosed speed, the vehicle stalled with a thumping sound coming from the engine compartment.

The manufacturer was not notified of the failure. The failure mileage was 128,000.

When driving the vehicle, I can smell gas fumes which caused nausea. I didn’t know it was worse in the back of the cabin where my children sit until I sat back there for a 3 hour trip. The smell was stronger there which led to headache, nausea and fatigue. It doesn’t seem to come from the vent, it seems from the entire body of the vehicle. This puts my children’s health at risk. And all of our lives because if we travel far enough breathing this in, it can lead to exhaustion which can cause a crash and put others’ safety at risk. I’m surprised to see there is no recall, yet, it’s been reported that there have been 1.5 million complaints. We are having the issue fixed next Wednesday, but we will be without a car (ford is not providing a loan vehicle) and the bill is extremely...

Without any warning, the engine and power system failed while on the highway. There was no system warning lights preceding the event, and the vehicle had be well maintained.

Upon excellerated take off the exhaust fumes fill the cabin. There has been a prior recall for such issues. This has happened multiple times over the entire time that I have owned it. It is getting increasingly worse and I worry for myself, my family and others. My local Ford dealership dismissed me every time I brought it up.

Timing belt broke and caused vehicle to stop running, this was after I took it to a mechanic who did a diagnostic and no issues showed up. Now, because of the timing belt breaking, the engine is irreparable and the entire engine will need to be replaced. It only has 116K miles. Another minor complaint is the front driver's side side windshield panel has come unglued. Luckily, the vehicle was stationary when I noticed it being loose. However, it could pose a safety risk. I have noticed other similar vehicles missing the same piece, so it seems to be a consistent problem with Ford Explorers.

My 2015 Ford Explorer is having fumes in the car. The dealership has charged me for an oil leak, cracked exhaust and now wants me to pay for a muffler. There is still exhaust fumes coming into the car making it hard to drive in the cold.

Water pump damaged the engine and water pump replacement cost is high and I cannot afford that kind of service because a stupid designed engine. The part is really cheap compared with the cost of the labor and hours to replace. Suggested from the mechanic replace the engine and the cost is high . I do not have a car anymore and they don’t want to do it.

In 2015, when I leased a Ford Explorer XLT, I was never made aware or otherwise notified that a host of Ford models, including the 2015 Ford Explorer XLT had a long known design flaw in which the water pump, encased in the engine block, had a history of prematurely breaking and causing engine coolant to enter the engine and mix with the oil, and also into the oil pan, causing total engine failure, with no advance warning to and at the peril of the vehicle owner or operator, when the vehicle may come to a complete standstill or stop in traffic or in any operation placing the operator at risk of injury or in jeopardy of causing an accident or being subject to becoming an accident victim, plus creating the need to replace a new engine or a rebuilt engine into the vehicle. catastrophic damage in 2011 to 2020...

Water pump leakage I noted that my Ford was leaking fluid and took it in to be serviced. Upon review it was determined that the water pump needed to be replaced as well as the timing belt. Ford Explorer models from 2011 to 2016 had the most water pump issues. Consumers have continuously reported complaints with a few of all the models having leakage issues. I am not alone in this and it looks like several are indicating a class action lawsuit should occur as Ford knows this is an issue and has not completed a recall. https://www.vehiclehistory.com/articles/all-about-the-ford-explorer-water-pump-recalls The loss of engine coolant through a leak in the water pump can damage the engine.
