Chronological view of owner reports
The contact owns a 2015 Ford Explorer. The contact stated while driving at an undisclosed speed, the HVAC system was inoperable. The vehicle was taken to an independent mechanic, who diagnosed that the water pump was faulty, causing coolant intrusion into the engine, and that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 140,000.
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 just never know. I take the EXPLORER to Ford for a diagnostic and they confirmed it was the internal water pump. This seems to be an issue and recalled because of a defective part or the way the vehicle was built. The leak can happen at any time and mine had 114,000 miles. My other 2010 Ford F150 has 180,000 miles and I have never had this issue. Needless to say, I had to for over $2,300 for the dealership to repair.
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.

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.
Waterpump
Water pump died at 80,000 miles. Seems in my research this is a common probably with class action lawsuits
When you drive the vehicle over 40 mph the vehicle let’s out a smell that’s very strong and you have to let the windows down so that you don’t feel sick. The smell makes you have headaches and feel lightheaded.

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 day diagnosing. I was quoted $2500 and my car will take a week to fix. Ford has not offered to pay for any of the repairs even though these poorly manufactured water pumps continue to go bad on thousands of vehicles. There are multiple class action lawsuits against ford for this reason!
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 models, with the replacement costs having to be borne by the owner of said vehicle because no recall had been undertaken, despite of their being a host of victimized owners. This incident happened to me and the 2015 Ford Explorer XLT vehicle I was driving. It occurred while I was in traffic and the exception caused total engine failure with no advance warning, no instrument panel warning and the entire engine had to be replaced at my personal cost of over $7,000. I attempted to negotiate with Ford Motor Company to no avail, and I had to expend the funds to acquire and install a rebuilt engine, at my own expense, to be able to continue to use the vehicle for my livelihood. Numerous correspondence with the dealership of origin, Liccardi Ford of Watchung, NJ, and the Ford Motor Company were fruitless. With all of the incidents and all the victims of this design flaw, a recall should have, in my opinion, resulted, but it did not. To my knowledge, which I have not been able to confirm, the design was corrected in newer models, but no assistance was afforded to the owners of the affected vehicles. I have sold the vehicle and it is not available for inspection.

Water pump went out and had to have my vehicle towed and I was out of my vehicle for a month and half... Faulty water pump and Ford knows this that is why they have a law suit against them. Then where they put this water put makes the cost even more!!! $1500 labor and $500 water pump then from the water pump going out it mixed oil and water through my engine and leaked all over my compressor so that went out so I had to change that also and that was another $1000.. FORD SHOULD BE HELD RESPONSIBLE FOR ALL THES FAULTY WATER PUMPS BECAUSE THEY KNOW THEIR IS A PROBLEM WITH THEM!@!@!@!@
