While driving at highway speed on a 2-lane highway with three children under the age of [XXX] in the vehicle, my 2018 Ford Explorer experienced sudden complete engine failure with no prior warning. No warning lights, no temperature gauge change, no unusual sounds. The vehicle went from operating normally to catastrophic failure instantaneously, forcing me to sharply cross active traffic to exit the roadway. The vehicle came to rest near a train track. The root cause was internal water pump failure. Ford's design places the water pump inside the engine, causing coolant to leak internally with no external indicators and no dashboard warning until catastrophic damage has already occurred. Ford did not install a coolant level sensor in the reservoir, and the only coolant warning available is an overheating alert, which never triggered. I had taken every reasonable precaution. Two thousand miles prior, an oil change showed no coolant contamination. One week prior, I physically checked the coolant level and it was within safe range. Ford's design gave me zero opportunity to detect or prevent this failure. This is a known recurring issue. Over 86 engine complaints have been filed with the federal safety agency for this model year alone and Ford has been aware of this defect since at least 2007. Despite class action litigation in both Canada and the United States, Ford has not issued a U.S. recall. Repair costs exceed $9,000. I am requesting the federal safety agency open a formal investigation and compel Ford to issue a U.S. recall.

The contact owns a 2018 Ford Explorer. The contact stated that while driving at approximately 30 MPH, the check engine warning light illuminated. The vehicle was driven to the residence and then to an independent mechanic shop, where a full diagnostic inspection was not performed; however, the mechanic suspected that coolant bubbled internally and the contact was informed that the head gasket might need to be replaced. The mechanic was unable to disassemble the engine for further inspection. The vehicle was then taken to a dealer, who diagnosed that the water pump needed to be replaced, and the vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 112,000.

My vehicles transmission has been replaced 2 times already (3 years apart)- now it is overheating. Absolutely no warning lights have came on at any time in regards to any of my situations - My vehicle is available for inspection at any time. When the transmission went in my vehicle, I was traveling on an interstate with my child. The dealer has confirmed replaced the transmission as it was still under the 5 year warranty - my vehicle is set to go back into the shop today to be inspected as to why it is overheating.

At 89k miles, my engine has failed, due to coolant intrusion, according to Ken Garff Ford Dealership in St. George, UT. I started having issues with rough start and timing miss and engine light came on. I immediately took it to Dealership and they did two repairs (tune-up) and subsequent gasket change because they said oil was getting into my spark plugs. It did not resolve the issue, took it straight back and now they're telling me I need a new engine. This comes 2 years after I had to pay $7k for a new transmission at only 60k miles. This is wrong and not OK that I am having to deal with this. I don't have $12k laying around for a new engine on a vehicle that shouldn't be having all these issues!

I purchased a 2018 ford explorer with the 2.3l 4 cylinder enginge in 2023. Withihn a year of my engine started to have issues hesitating when accelerating. Then it overheated and I realized my coolant was disappearing but wasnt pooling anywhere.. It was evaporating because it was leaking into my spark plugs. When I changed plugs I noticed oil or coolant on two of them I called ford about it because my engine has a pending lawsuit for this problem it kept getting worse . I dont have the money for the repairs and I asked them if they could do a good faith repair and I was denied. As of 4/16/2026 my engine failed and my coolant is filled with oil because of the defective engine that they knew about since 2010

Upon startup rough idle and check engine light came on. Mechanic confirmed cylinder head thinning causing fluid leak into first cylinder. A mechanical note verifies but Ford won't issue a recall. Apparently Ford has know this for years with Ecoboost engines. I don't want to become a victim of vehicle dying in the middle of traffic. Have seen several complaints from Ford owners with no fixes by Ford.
