2016 Ford Explorer: engine failure

Filed Sep 8, 2026 · Engine · MI

I am writing to report a severe, inherently dangerous engineering defect regarding the internal water pump design on the 2016 Ford Explorer equipped with the 3.5L naturally aspirated V6 engine.On September 8, 2026, my vehicle experienced a sudden, catastrophic primary seal failure of the internal water pump while operating. The vehicle immediately began dumping large quantities of engine coolant onto the ground from the designated engine block weep hole located on the lower passenger side. Because Ford engineered this specific engine with the water pump hidden entirely behind the front timing cover and driven directly by the engine's timing chain, any mechanical failure of the pump poses an immediate, severe safety risk to the driver and occupants. If the secondary pump seal fails or the weep hole becomes obstructed, coolant dumps directly into the engine crankcase, mixing with the engine oil. This sudden loss of lubrication can cause the internal pump bearings to seize rapidly, leading to the timing chain snapping or jumping tracks.The consequences of this design create two distinct, critical safety hazards:Sudden Engine Stall at Speed: A seized water pump or broken timing chain will cause an instantaneous, un-commanded engine shutdown while traveling at highway speeds. This immediately cuts off the vehicle's power steering assist and power brake booster, placing the driver at extreme risk of a high-speed collision. Passenger Cabin Hazmat Hazard: A major coolant dump underneath the engine bay onto hot exhaust components generates blinding steam and toxic chemical fumes that can enter the vehicle’s HVAC system, severely impairing driver visibility and breathing.This internal, chain-driven water pump design is a known, systemic manufacturing defect that forces vehicle owners to pay between $3,000 and $5,000 in preventative labor to fix an auxiliary cooling component before it destroys the entire engine block. I urge the federal safety agency to open a formal safety investigation int

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 as massive issues with the turbos and the cam phasers that also commonly are causing catastrophic engine failures despite routine preventative maintenance being performed. And the a pillar recall issue. I had it inspected December of 2024 and determined it needed them replaced. I was not given a time frame when that would be completed. I got a call over a month ago from the dealer saying to call them to schedule a repair. I did so and then was told that while I was on the list they still are unable to get any parts from Ford to repair this mandated recall and also cannot get a timeline on when said parts would be available. I’m almost six months past them saying it’s been ordered and still no idea when it’ll be repaired. And now a second recall was just announced for the b post coverings and I’m sure this will be just as bad. As many issues as this car is having I think Ford should have to pay for a lot more recalls than they have so far. I also had to have two other recalls fixed that the selling dealer didn’t address before selling to me.

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.

The contact owns a 2016 Ford Explorer. The contact stated that while driving 45 -50 MPH and attempting to merge towards the left around a curved road, the power steering was seized. The steering assistance failed and to service the steering assist warning illuminated. The contact continued to drive and the power steering self-corrected as they continued to drive. The vehicle was taken to the dealer who diagnosed that the power steering assist had failed. The vehicle was taken to a certified mechanic who replaced the power steering unit with an aftermarket part. Approximately one year later, while driving approximately 40 MPH when the failure reoccurred. The contact managed to slightly loosen the steering wheel, however, while continuing to drive, the steering wheel would continue to stiffen causing them to have to aggressively maneuver the steering wheel. The same warning lights had illuminated. After the vehicle was driven home, the steering wheel completely seized. The vehicle was not taken to the dealer. The vehicle was not diagnosed or repaired a second time. The manufacturer was made aware of the failure and filed a case. The failure mileage was unknown.

In addition, the check engine warning light illuminated after the failure had occurred. The vehicle was driven to the shoulder of the road. The contact stated that when the vehicle was parked, the engine seized. The contact inspected the vehicle and noticed there was water from the water pump on the ground underneath the vehicle. The contact drove the vehicle to a nearby auto parts store. The contact was informed that the failure might be due to the coolant pump failure. The technician refilled the coolant reservoir with water. The vehicle was driven to the residence. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The dealer was made aware of the failure. The manufacturer was made aware of the failure. The failure mileage was approximately 54,000. The VIN was unavailable.

*Premature water pump failure that is housed in the timing chain chamber and driven by the timing chain. Component is not available for inspection as of this complaint because vehicle is being repaired. *Possible sudden catastrophic engine failure due to water pump failure, which will put safety of driver, passengers, and others at risk. *I am not aware if problem has been reproduced or confirmed by dealer or other independent services. Several dealers that I contacted did expressed that it was a "bad design". *I am not aware if component has been inspected by the manufacturer or others. *The only warning sign of premature pump failure was a small puddle of coolant under the vehicle. This happened at around 70K miles and the dealer was informed, but according to the Ford technician, upon inspection, no sign of coolant leak was found. At approximately 82K, the dealer was informed about a sudden coolant leak, and again, the Ford technician did not find the leak. It wasn't until I personally took a video of the coolant leaking and showed it to them, that they "diagnosed the problem correctly".

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.
