2017 Ford Explorer: engine failure

Filed Oct 24, 2026 · Transmission · CO

About 3 years and 3 months after a Power Control Module reflash was done in March 2021 under the Customer Satisfaction Program (CSP) 20B27, vehicle was brought to Ford dealership on 06/07/2024 with mileage at 79,730 for multi point inspection due to vehicle runs rough and hard time accelerating. Diagnostic code was P0316. Service tech recommendation was to replace engine for $14,000.00 including parts and labor (declined recommendation). Brought vehicle to another dealership but found no codes. Instead replaced engine motor mounts, sparkplugs, and air filter due to noticeable vibrations. Dealership service tech inspected engine but found no abnormal findings. Went to another Ford dealership on 10/08/2026 to check Code P0299 that appeared on OBD test and for further inspection due to sluggish acceleration from full stop and slows down going uphill. Ford's guidance stated that torque converter failing due to mileage, acceleration/power loss from dead stop. Recommended fix was to replace the transmission for $8,461.03 (declined recommended service). On 10/23/2026, I picked up my vehicle from the dealership. During my return journey from the dealership, I encountered the same sluggish acceleration. A safety hazard that is attributed to a malfunctioning torque converter, a know problem for Ford. Consequently, Ford dispatched CSP 20B27 to assist in safeguarding the transmission converter from overheating. Regrettably, this intervention proved ineffective in mitigating the problem. Ford issued CSP 20N07 to extend warranty coverage of the automatic transmission torque converter for 12 months from RO date which in my case, RO date on CSP 20B27 was 03/19/2021. Despite the 12-month eligibility period not being met, my vehicle should have remained covered. Initially, Ford was aware of a transmission torque issue and was attempting to resolve it through CSP 20B27 and CSP 20N07. Currently, mileage is at 85K miles but I'm hesitant to drive due to safety concerns.

Sudden catastrophic engine failure due to coolant mixing. This resulted in a safety issue due to time and location of the event. From online consumer reports this event happens just after 100,000 miles to the 2017 Ford Explorer SUV's and is a KNOWN event that Ford has NOT disclosed. Regular maintenance can NOT prevent this event and stopping the use of the vehicle only helps if it is immediate and the problem known. That Ford hasn't disclosed this possibility of failure nor suggested preventative measures is a safety concern.

Engine hesitated, kept hesitating/slowing down until 2017 Ford Explorer just stopped. Towed SUV to Koons Ford Service Center. Charged $200 for diagnostic assessment. Informed that oil/coolant mix due to water pump failure. Diagnose: replace Engine Long Block and Hardware and thermostat. Costing $11,195.04 for job. Never mentioned what happened to cause this. At another dealership, mechanic told us of the federal safety agency Recall 25V685000 regarding this malfunction. Note: Koons Ford has had a "history" with this SUV, only working on recalls when we push the issue. Also, requiring a $200 diagnostic charge each time the vehicle is seen. This location is where we bought the vehicle.

I am filing a safety complaint regarding my 2017 Ford Explorer XLT with the 3.5L V6 engine due to a known internal water pump design defect. The water pump is located internally and driven by the timing chain. When it fails, coolant can leak directly into the engine crankcase and mix with motor oil instead of leaking externally where it would be easier to detect. This creates a serious safety hazard because the engine can suffer catastrophic damage, sudden failure, loss of power, or complete shutdown, sometimes with little or no warning. In my case, the vehicle experienced symptoms consistent with internal water pump failure, including my car overheating out of nowhere, forcing me to coast to the side of the highway in very unsafe conditions. This defect can destroy the engine and create dangerous driving conditions, especially if power loss occurs while driving with children or passengers, thankfully I didn't have any of my three children with me when this happened. This appears to affect many Ford Explorer vehicles from similar model years, and numerous owners have reported similar failures. The repair cost is extremely high because replacement often requires major engine disassembly or full engine replacement. I am currently financing this vehicle with a balance of $14,000 left to pay and have already paid close to $28,000. This is extremely unfair and the cost to repair is close to $5,000. I don't see a way for myself to afford that. I believe Ford should be required to address this issue because: The design can allow coolant contamination inside the engine without obvious external leakage. Failure can occur suddenly and create safety risks. Repair costs are excessive for what appears to be a widespread defect. Owners may not receive sufficient warning before catastrophic failure. I am requesting that the federal safety agency investigate this defect for safety implications and determine whether a recall or broader manufacturer accountability is warranted. Thank you for your time.

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.

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
