2016 Ford Explorer engine problems

“On approximately 09/02, I took my 2016 Ford Explorer to an authorized Ford dealership for recall-related PCM service. After the recall service was completed, I experienced additional problems with the vehicle and returned on 09/4 and I also called the same dealership that same day because I believed something was wrong following the repair. The dealership replaced the battery but did not perform additional diagnostics unless I paid out of pocket. I was unable to immediately afford those diagnostic charges, so I later sought additional diagnosis. The vehicle continued to experience drivability/electrical problems, including misfire symptoms and eventually a no-start condition. After further testing, another authorized Ford dealership diagnosed the PCM as faulty. I contacted Ford Motor Company because I am concerned that the recall service, programming, or work performed during the recall may have contributed to the PCM failure. Ford closed my case because the recall was marked completed and stated that my vehicle is outside its warranty period. I returned the vehicle two days after servicing dealership as the recall repair to report problems. I am requesting…”

“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…”

“Vehicle: 2016 Ford Explorer 2WD V6-3.5L VIN: [XXX] rchase: January 20, 2026 Odometer at Purchase: 70,929 miles (fraudulent — true mileage approximately 123,779 miles) Dealer: Drive Time Car Sales Company LLC, DBA Drive Time, 8805 E Adamo Dr, Tampa, FL 33619-3525 Narrative — Copy and Paste Into NHTSA Online Form: On January 20, 2026, I purchased a 2016 Ford Explorer 2WD V6-3.5L (VIN: [XXX] ) fr [XXX] Sales Company LLC, located at 8805 E Adamo Dr, Tampa, Florida 33619-3525. At the time of sale, the vehicle had three open, unrepaired federal safety recalls: 1. NHTSA Recall 19V435 / Ford 19S17 — Rear Suspension Toe Link Replacement (initiated June 26, 2019, affecting 1,194,173 vehicles). The rear suspension toe links may fracture, causing sudden loss of vehicle handling and risk of crash. 2. NHTSA Recall 21V537 / Ford 21S32 — Rear Suspension Toe Link Cross-Axis Ball Joint (owner notifications mailed March 2022, affecting 644,055 vehicles). The cross-axis ball joint may corrode and seize, causing toe link fracture and loss of steering control. 3. NHTSA Recall 25V347 / Ford 25S53 — B-Pillar Door Trim Detachment (owner notifications mailed June 2025, affecting 492,145…”

“Coolant leak in the cylinder head grooves that builds up on the seal and leaking into cylinders. Causing coolant loss, white smoke and engine overheating. This issue has left me stranded on the interstate and in danger with potential engine fires. These incidents have exposed myself and the general public to unnecesary safety hazards.”

“While driving the crankcase sensor malfunctioned and caused my vehicle to stall without warning, this is a safety issue because of you are driving at highway speeds this will prevent the vehicle from being controlled properly to get to the side of the road. This sensor does not give any engine codes suggesting that it needs replaced until it goes out completely. The check engine light did not come on until after the component failed. I ordered a new part directly through Ford and even they said "yes that part will go out without any warning at all and will shut the engine down completely". When this sensor went out, it also caused pressure to build up in the engine which in turn has led to several other components that now need to be replaced. I have a had a mechanic look at it, and it now requires a turbo intake hose and a new turbo because the pressure that was built up in the engine due to the crankcase sensor going out burst the turbo intake hose and prevented the turbo from working correctly. It's approximately $4,000 in repairs due to a $150 part going out.”

“The contact owns a 2016 Ford Explorer. The contact received notifications of NHTSA Campaign Numbers: 21V316000 (STRUCTURE), 24V031000 (STRUCTURE), and 25V347000 (STRUCTURE). However, the parts to do the recall repairs were not yet available. The contact stated that while the vehicle was parked, the contact became aware that rainwater was leaking inside the vehicle and standing water had accumulated on the carpet. The water was leaking from the front door, the roof near the dome light, and the glove compartment. The contact was unsure of where the water was entering the vehicle. The contact stated that there was a musty odor inside the vehicle. Most recently, while driving at an undisclosed speed, there was an abnormal burnt odor inside the vehicle. No warning lights were illuminated. The vehicle was taken to the dealer; however, the vehicle was not diagnosed or repaired. The contact stated that the check engine warning light was constantly illuminated since the vehicle was purchased. The manufacturer was not made aware of the failure. The failure mileage was unknown.”
