2017 Ford Explorer Engine Problems

Oil is leaking onto my spark plugs and fouling them out. Also took my car into dealership and parts are not available for the recall for the rear toe links.

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

Complete failure of the water pump at 58000 miles.

Coolant keeps going low. No visible leaking spots. Been to 2 mechanic's. Both said Ford defective engine block. Coolant leaking into cylinder 1. Recommended engine replacement. Check engine light. Verified 300 # codes. Misfire. Foul and rough start ups. Been on 4 or 5 months.

October 2025 check engine light came on, took to mechanic showed misfire in cylinder two and three. Replaced all plugs and coil packs, engine light went off. Engine light came back, hard start on November 26,2025 showed misfire in cylinder 2 and 3. Replaced those coil packs again, engine light off. February 2, 2026 engine light back on, hard start with vibration. Took vehicle to Mtn View Ford in Chattanooga to have diagnostic test done.

The car makes a ticking/rattle sound on cold startup. Preliminary diagnosis is the cam phasers. This is a 2017 Ford explorer with 77,000. It is the same 3.5L V6 ecoboost (GTDI) engine that was in Ford Customer Satisfaction program: 21N03. The issue mirrors tgat in the program document, but the Explorer is not covered by the program.

I brought my vehicle from a used certified dealer at the time of test drive I asked why such a rough transition when going from gear to gear and I was told it was the ECOBoost engine packed with power. Fast forward after multiple repairs and recalls on this vehicle I’ve made it to my breaking point when my SUV shut down as I was turning onto a busy street coming from my son’s school. The engine literally cut off almost causing a head on collision. This idle function is extremely dangerous. I had multiple belts repaired and many things checked after my car overheated and couldn’t find the culprit. One mechanic explained my fan wasn’t working to assist in cooling off the engine and the vents/grill in front of car was shut causing the engine to over heat. After opening the vents and connecting the car to diagnostic machine there were no codes to fix. Over the next month my suv would become significantly worse rattling when I stop at a red light almost drifting into a car in front of me. No longer overheating but now feeling the car physically shifting gears as if I drive a stick shift and I have an automatic transmission. After doing careful research I learned was some recalls on the fan and eco boost engine explaining the same issues that I’am currently having. Don’t mention fixing the recalls because all the certified dealers are 2-3 weeks behind on fixing and diagnosing these same vehicles. They won’t loan you a car while being repaired which is another cost associated with this vehicle. Please look into this ecoboost engine and overheating issues. Also I was told my engine would go soon do the oxygen intake not exchanging enough oxygen causing oil to push into spark plugs and other parts of the engine it doesn’t belong. This SUV is a complete lemon and should be recalled right away before someone dies from this awful feature. Just last week I saw someone on the interstate with my same vehicle stopping mid traffic. This is dangerous!!!

Own a 2017 Ford Explorer 2.3L EcoBoost with 116K miles, out of the blue the vehicle started to overheat the engine, with no coolant left in the reservoir. Took it to a mechanic who stated that the engine is not that old and that it was unsure of why the head gasket was blown. It is believed by many including a Class Action Law Suite that Ford is aware of the possible overheating issues with their EcoBoost engines.

There was cam phaser situation that i was never informed of when this car was purchased. I just hit 80 k and i am now having issues. It appears there is a lawsuit for this. What is ford doing to fix.

Coolant on garage floor. Researched and found common among this engine, Called dealer. Said do not drive and get to dealer. Can cause engine seizure and breakdown if internal coolant leakage has started. Dealer stated they see at least one a week of this water pump problem.
