I’ve had three transmissions replaced from 2023 to 2026. Ford no longer makes 2017 Ford Explorer transmissions so I keep getting bad parts. In 2026 engine light came on , coolant leaking into cylinders, $11K to fix. This car has left me stranded on the side of the road , not to mention months at the dealership trying to find transmission parts. Ford Corporation refuses to buy back vehicle based on lemon law. Rear seatbelts defective.

Car started to overheat randomly, no signs of issues before, replaced the water pump for the second time in a year (2025 and again 2026). Continued having issues & white smoke puffing, turned out to have an oil leak due to piston rings being melted to the pistons, causing all spark plugs (prior repalced) and engine to be bad. Car is continuing to worse, sputters just sitting after you start it. Smells like burnt oil. Too dangerous to drive so it’s been sitting for weeks after pouring $3,000 into it to not have it fixed and now needing a new motor.

My 2017 Ford Explorer suddenly started vibrating intensely whenever I am at a stop or start slowing down. Episodes of hesitation when attempting to take off from a start with significant rpm surges. I am told I need to have my torque converter replaced. My vehicle has 84,697 miles on it, and was bought brand new from a dealer. I already had to have a new engine a month ago. This level of multiple engine and powertrain failures puts consumers and other drivers at risk for harm on the roadway. Not to mention the economic and employment impacts it has on the vehicle owners.

I am reporting a serious safety concern with my 2017 Ford Explorer. The vehicle currently has approximately 93,752 miles and has become increasingly unreliable and unsafe to operate. On April 9, 2026, while my wife was driving home from work, the vehicle overheated, creating a dangerous situation and risk of sudden breakdown. This is especially concerning as the vehicle is used to transport children. Recently, after taking the vehicle in for an oil change, I was informed of multiple additional problems (three separate issues) affecting the vehicle. In addition, the check engine light remains on continuously, even after attempted repairs, indicating unresolved underlying problems. I have also previously attempted to have a recall repair completed, but was told that the necessary part was unavailable and that I would be contacted when it became available. Months later, I have still not been contacted, and the recall issue remains unresolved. Based on my experience and publicly documented issues, this appears consistent with known defects associated with this model, including reported water pump failures leading to engine overheating, rear suspension issues affecting control, and concerns regarding exhaust fumes entering the cabin. This is not normal wear and tear, but a potential safety-related defect. It is a serious concern that known recalls and defects cannot be repaired due to lack of available parts, leaving the vehicle in an unsafe condition. I am also concerned about the risk of continuing to operate this vehicle and potentially causing an accident that could injure myself, my family, or others on the road. This risk is heightened by the lack of timely communication and resolution regarding known defects and recalls. I am requesting investigation into these issues to prevent harm to drivers and passengers

Vehicle experienced white exhaust smoke due to oil entering the exhaust system, caused by turbocharger failure. This led to contamination and failure of all O2 sensors, requiring full replacement, along with replacement of both turbochargers. The radiator also failed and had to be replaced. This appears to be a cascading mechanical failure affecting multiple major systems, including the engine, fuel/propulsion system, and electrical components, rather than normal wear and tear. The failure rendered the vehicle inoperable, leaving me without transportation during a period of financial hardship. The severity and extent of repairs raise concern about a potential broader defect. This also created a safety concern due to excessive exhaust smoke and reduced vehicle reliability while in operation.

The 2011 to 2019 Ford Explorers have a huge issue with them. The internal water pump on my 2017 Ford Explorer 3.5L engine failed. The failure caused coolant to leak into the engine crankcase, where it mixed with the engine oil. This contaminated the oil and led to catastrophic engine failure and seizure. The vehicle has already been brought to a dealership for service and is available for inspection upon request. This failure created a serious safety risk because the engine could have seized suddenly while the vehicle was in motion. If I had not caught the issue early, it could have resulted in a complete engine shutdown without warning, leading to loss of power, reduced steering control, and inability to accelerate in traffic. I have a strong understanding of vehicles and was able to recognize the warning signs, but the average driver would likely not identify these symptoms. Without that knowledge, this type of failure could easily occur without warning and put both the driver and others on the road at significant risk. Yes. The issue has been confirmed by both an independent mechanic and the dealership as a failed internal water pump. Coolant was beginning to leak internally into the engine and oil pan, where it mixed with the engine oil. The symptoms—coolant leaking near the oil pan, loss of coolant, lack of heat, and eventual engine failure—are consistent with this type of failure on this engine. The vehicle has been inspected by both the dealership and my independent mechanic. It is currently at the dealership for service and remains available for further inspection if needed. There were early symptoms, including a coolant leak, bubbling in the coolant reservoir, and loss of heat inside the vehicle. However, there were no clear warning lights or alerts indicating imminent engine failure. The engine did not overheat prior to failure, and the final seizure could have occurred suddenly without adequate warning. These symptoms only appeared about one day prior

Vehicle was brought to an authorized Ford dealership for coolant leak. The dealer confirmed a coolant leak originating from the internal water pump. The water pump on this engine is chain-driven and located inside the engine behind the timing cover, requiring approximately 12 hours of labor to access and replace. This is a known design defect affecting millions of Ford vehicles with the 3.5L Cyclone/Duratec engine across multiple model years (2007-2020). The defect allows coolant to leak past the bearing seal, with potential to mix with engine oil and cause catastrophic engine failure. This is a serious safety risk as failure can occur without warning while driving. The problem was confirmed and documented by the Ford dealership. No warning lights appeared prior to the leak being discovered. Repair cost exceeded $4,300. This defect was the subject of a federal class action lawsuit (Roe v. Ford Motor Company, Eastern District of Michigan) which was settled confidentially in January 2024 without a recall being issued. Ford has not notified owners of this known defect or offered any remedy program to US customers, despite a Canadian class action resulting in relief for affected owners there. I am providing the cost invoice but will provide an itemized invoice once repairs are finished.

It is known that for the specific year make and model that the water pump goes out around 100,000 miles. This water pump was built as an internal water pump, which is not typical for most cars. in order to fix this part, the engine has to be taken out and lots of parts have to be disassembled Just to get to it. The part Itself is fairly cheap, but the labor cost thousands of dollars due to where it is located. Ford knowingly built this car and put that pump where it is at and therefore should be reliable to pay the cost when it is so common that this part goes out around 100,000 miles. if it is a known issue that occurs on these models frequently then it should become a recall because a failing water pump can cause significant issues within the engine and make the vehicle in operable.

I periodically have unintended acceleration ; it has occurred off and on for the past two years . The Ford dealer said no faults were detected so they can't fix the problem . It most often when I am shifting into reverse then the RPMs increase dramatically and when I put it in neutral they shoot up even more . A few days ago I was putting the car into the garage , waiting for the door to open , with my foot on the brake and the shift in drive when the RPMs started to increase . Feeling the car starting to move I shifted to neutral when the RPMs shot up tremendously . This is a dangerous situation where someone can get injured or killed . Ford should be able to correct the problem !!!

At 28,000 miles, the vehicle emitted black smoke from the exhaust. Despite the mechanic’s efforts to identify the issue, no diagnostic codes were detected. Currently, the vehicle has accumulated 100,000 miles. The engine suddenly lost the ability to accelerate beyond 20 miles per hour. After several months of repairs involving multiple turbo replacements, it was determined that the engine was severely damaged and should have been replaced over 50,000 miles ago. The engine was subsequently replaced, but only a year later, it failed again. After replacing the first engine, the vehicle’s performance deteriorated significantly. The vehicle required another visit to the shop for several months, resulting in another engine replacement. Over the course of several months, the vehicle lost all power and exhibited difficulty shifting into reverse. Consequently, it failed to reverse and was involved in an accident.
