2017 Ford Escape

NHTSA Complaint SummaryVehicle: 2017 Ford Escape SEEngine: 1.5L EcoBoostVIN: [XXX] Defect: Engine Block Design Flaw / Coolant IntrusionTechnical Description of the Issue:My vehicle is experiencing a well-documented manufacturing defect specific to the 1.5L EcoBoost engine. The engine block was designed with a "v-groove" between the cylinders that is prone to structural failure. This allows engine coolant to leak into the combustion chambers (coolant intrusion) and allows engine oil to contaminate the cooling system. My vehicle currently exhibits "milky," tan-brown sludge in the coolant reservoir, confirming that oil and coolant are cross-contaminating due to internal engine failure.Extreme Safety Hazards and Dangers:This defect creates several critical safety risks for the driver, passengers, and other motorists:Sudden Loss of Power at High Speeds: The mixing of oil and coolant destroys the engine’s ability to lubricate internal bearings. This can lead to a catastrophic engine seizure while the vehicle is in motion, causing an immediate loss of power and power steering, which creates a high risk of collisions on highways.Engine Fire Risk: When coolant enters the combustion chamber, it can cause severe engine misfires and overheating. Overheated oil or pressurized coolant spraying onto a hot exhaust manifold during a mechanical failure presents a significant fire hazard.Hydro-locking: If coolant floods the cylinder while the vehicle is in operation, the engine can hydro-lock, causing the engine to stall instantly and potentially throwing metal debris onto the roadway, endangering other drivers.Visibility Hazards: Excessive white smoke from the exhaust (caused by burning coolant) can suddenly obscure the driver’s rear-view visibility and the visibility of trailing motorists.Conclusion:Ford Motor Company was aware of this defect, as evidenced by Customer Satisfaction Program 21N08 and TSB 19-2346. However, because these programs have arbitrary expira INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (

The failure appears to involve the vehicle’s auto start/stop system and related electrical control systems, including the battery management system and/or body control module. The vehicle shuts off unexpectedly while driving and fails to automatically restart, displaying “Auto Start/Stop – Manual Restart Required” and “Shift to Park.” The vehicle is available for inspection upon request. The vehicle has shut off unexpectedly in active traffic, causing a sudden loss of power. This creates a dangerous situation where I am unable to accelerate or move with traffic flow, increasing the risk of being rear-ended or involved in a collision. This has occurred on public roads with other vehicles present, putting both myself and others at risk. The issue is intermittent and has not consistently been reproduced on demand. However, it has occurred multiple times during normal driving conditions. I am in the process of having the vehicle inspected and documented by a dealership. The issue has been reported to the manufacturer, and a case has been opened with Ford Motor Company. At this time, the vehicle has not yet been inspected by police or insurance representatives. There were no consistent warning lamps prior to the failure. At the time of the incident, the vehicle displayed messages including “Auto Start/Stop – Manual Restart Required” and “Shift to Park.” These messages appeared simultaneously with the loss of power. The issue has occurred intermittently without advance warning.

2017 Ford Escape 65,000 miles,1.5l coolant intrusion.#2 cylinder misfire code. First thing upon raising the hood noticed and acknowledged there was no coolant in resevoir. Attempting to replace spark plugs. Removed/replaced #4 plug. Attempting to replace #3 spark plug, plug broke off. Researching and collaborating with reputable mechanic concluded that short block coolant intrusion has occurred. Upon disassembly have encountered turbo boost and catalytic converter full of oil, also needing replaced. Head has been sent to machine shop for inspection and repair. Presently awaiting for repairs to be completed and costs established. Present estimate over $5000. I paid cash for this vehicle in 2019. Vehicle had been leased for 2 years previous. Vehicle had 20,000 miles on it. Ford was well aware of the coolant intrusion (bad engineering) is before they sold me the vehicle in November 2019. They never mentioned or offered any warranty specific to this issue. They sold me a a vehicle knowing that if enough things went wrong while driving this vehicle, catastrophic situation was possible. They should have corrected this issue before they sold it to the next customer.

My vehicle was inspected by a mechanic after experiencing sudden loss of power and stalling while merging onto the expressway in active traffic. At the time of the incident, the vehicle became unable to accelerate properly, creating a serious safety hazard due to surrounding vehicles traveling at highway speeds. The mechanic determined that the fuel pump had failed. During inspection prior to replacement, the mechanic identified metal shavings present in the fuel system, which appear to have originated from the fuel pump. These metal fragments contaminated the system and pose a risk of further engine damage. This failure appears to be related to a known issue involving fuel pump defects in Ford vehicles. The design and/or function of the fuel pump may allow internal deterioration that leads to system-wide contamination and potential engine failure. This issue presents a serious safety concern due to the risk of sudden stalling and loss of power while driving, particularly during high-speed merging conditions.

The **engine system** failed due to **coolant intrusion into cylinder 2**, causing engine misfires and loss of power. This condition is consistent with known EcoBoost engine defects in this model year. The vehicle is available for inspection upon request. This failure created a **safety risk** due to potential **loss of power or stalling while driving**, increasing the risk of a crash. An additional issue exists with the **electrical system**, specifically the **driver’s door control panel circuit**, which intermittently malfunctions and affects vehicle operation. The engine issue has been **confirmed by diagnostic trouble codes indicating a cylinder 2 misfire**. Dealer confirmation: **UNKNOWN**. The vehicle has not been inspected by the manufacturer, police, or insurance representatives. Prior to failure, the vehicle displayed a **check engine light**, rough idle, and misfiring. Electrical issues occurred intermittently. Exact onset date is **UNKNOWN**.

While driving at a constant speed on the highway, the transmission shifted down a gear and revved into very high RPMs. I was dramatically slowing down despite pressing on the gas pedal. The car didn't provide any power and just revved while I had cars next to me going at highway speeds. Managed to get off the highway, a transmission fault indicator popped up on the dash. The car no longer was able to move. I had the car towed to the Ford Dealership. This car has a bad transmission at ~97,000 miles. Prior to this, I felt like the car's transmission maybe wasn't shifting on time but didn't make much of it. This could have easily resulted in a crash. Turns out this is a very well known problem with the Ford Escape. My friend has a 2016 Ford Escape who recently paid 8000$ for a new transmission. This is clearly unsafe and the failure is definitely premature.
