2017 Ford Escape: misfire or rough idle

Filed Nov 9, 2026 · Engine · MI

2017 Ford Escape with the 2.0L Ecoboost Engine. Engine failed with the known coolant intrusion issue with only ~65,000 miles on it. Engine started misfiring, and the check engine light came on (solid, not blinking). No leaks under the vehicle. Within 2 days, the cabin lost heat while running the defroster on a cold morning. Brought vehicle to Ford dealer where it was diagnosed for low coolant (no external leaks) and then coolant was found inside cylinder 2. It was recommended that I replace the engine long block, and was told that the replacement long block no longer has the same issue as the original. The original engine could have failed and stopped operating while I was driving putting me, and others, in a dangerous situation, and could have potentially started a fire. I am by far not the only Escape owner experiencing this; the service advisor that I talked to at the dealer admitted that he has seen "a lot" of Escapes with this issue, and there is an ongoing class action lawsuit (see below): XXX . The lawsuit alleges, among other things, that Ford Motor Company: failed to disclose that these vehicles have a defect that causes coolant to leak into the engine’s cylinders, which can cause corrosion, oil dilution and contamination, and engine failure; and failed to disclose these defects create a safety risk, because the lack of coolant created by the leaks causes overheating and can result in the cylinder head cracking, total engine failure, and/or engine fires.

The contact owns a 2017 Ford Escape. The contact stated that while starting the vehicle, the vehicle was shaking with the messages, " Cylinder #1 Misfire" and "Coolant Level Low" displayed. The coolant level was low. The vehicle was taken to an independent mechanic, who diagnosed a misfire in cylinder #1, replaced the spark plugs, and added coolant; however, the coolant level was low within the week and coolant was added. The vehicle was taken to the dealer, who determined that the engine needed to be replaced. The manufacturer was notified of the failure by phone and informed the contact that the vehicle was out of warranty. The failure mileage was 93,692.

1. The EcoBoost engine block suffered a severe structural failure caused by a factory manufacturing defect known as internal cylinder block coolant intrusion (as documented in Ford TSB 19-2208). Antifreeze leaks directly past the cylinder wall block grooves into the combustion chambers. This vehicle is currently parked and is fully available for physical inspection upon request at the location provided. 2. The engine suffered a sudden, severe mechanical malfunction while driving, causing an immediate drop in cylinder compression, engine misfires, and a dangerous loss of control and motive power. Driving a vehicle prone to sudden stall or failure creates an extreme hazard on public roads, dramatically increasing the risk of a high-speed rear-end collision or stranding the driver in live traffic without propulsion. 3. Yes. The vehicle’s loss of coolant, engine misfire codes, and cylinder block leak characteristics were physically inspected and confirmed by a private, independent auto mechanic. 4. The vehicle has not been inspected by the police or insurance as no crash has occurred yet. Ford Motor Company's customer service and Tier 2 Automotive Consumer Operations (ACO) divisions have been formally notified of the defect, and corporate Case File #CXH-0934-5907 was opened. However, a physical dealership inspection has not been completed due to the manufacturer's refusal to waive upfront diagnostic fees for an out-of-warranty vehicle. 5. Prior to total engine failure, the vehicle displayed an aggressive engine overheat warning indicator on the dashboard. The reservoir was found entirely stripped of coolant, with no visible external fluid leaks underneath the vehicle. These active symptoms and high engine temperature alerts first appeared suddenly on the dashboard on the day of the breakdown.

The engine light on my 2017 Ford Escape EcoBoost 2.0L has come on a couple times in the last few months. My trusted mechanic has diagnosed the following codes: P0301 and P0316 - which indicates cylinder misfire and misfire detected on start up. There is an active TSB 22-2226 (Coolant intrusion into Spark Plug/Cylinder Bore) that matches up with those codes. This is my daughter’s primary vehicle and we are not comfortable with her continuing to drive it for fear of total engine lockup. I took it into my local dealership to have them do their own diagnosis and to contact Ford corporate to determine the appropriate path to resolution. Current mileage is approximately 72,700 miles.

The coolant has been leaking into the cylinders the symptoms were violent shaking, low coolant, white smoke, misfires, and engine light and warning on. My safety and others safety were put at risk because if the motor is not replaced it can become a fire hazard and it could break down on the road endangering mine and others lives. The problem was diagnosed by a ford dealership and cost me $201 to just diagnose where they quoted me $14,000 to replace. It was inspected by the manufacturer (dealership). About 3 weeks ago there was an “Engine Fault Service Now” code on the screen then a couple days later the engine light came on and it was either constant or blinking.

It is common knowledge that my particular vehicle has a known engine defect - coolant intrusion - that in effect renders the engine inoperable eventually in models from 2013-19. Mine is a 2017. It was sold to me without anyone referencing the known engine issue. Over the last couple of years, my family was nearly stranded when the car suddenly began to experience shuddering, very rough driving, coolant disappearing and having to be replenished, and the engine coils misfiring and having to be replaced. Now, the engine has failed and is in need of more than $4,000 in repairs. While Ford did not issue a recall, it did alert its dealerships to the known manufacturing defect. As a consumer, I was NOT told of this problem during the sale.

Vehicle Information: Year/Make/Model: 2017 Ford Escape Titanium Engine: 2.0L EcoBoost 4-Cylinder Drivetrain: All-Wheel Drive (AWD) Current Mileage: Approximately 118,000 miles Description of the Safety Problem: The vehicle experienced a sudden and severe loss of engine coolant with no external leaks visible on the ground. Diagnostic inspection revealed that engine coolant is intruding internally into the engine cylinders due to a known structural defect in the Ford 2.0L EcoBoost engine block/head gasket design.Prior to diagnosing the failure, the vehicle exhibited rough idling, misfires, and white smoke from the exhaust due to coolant burning in the combustion chambers. Unrelated components, including the ignition coils, were previously replaced in an attempt to correct the misfires before the internal coolant intrusion was identified as the root cause.This defect poses an immediate safety hazard. The internal coolant loss causes the engine to overheat rapidly and threatens to force the vehicle into an abrupt emergency "limp mode" or cause complete, sudden engine failure while driving at highway speeds. This creates a severe risk of a rear-end collision or stranding the vehicle in active traffic without warning. Ford has failed to issue a recall for this systemic powertrain defect, leaving consumers to operate unsafe vehicles or face catastrophic out-of-pocket engine replacement costs.

The vehicle suffered catastrophic engine failure at 72,000 miles due to a known Ford EcoBoost manufacturing defect where engine coolant leaks internally into the cylinders. Upon starting the vehicle in the parking lot, the engine began misfiring violently with blinking check engine light. The vehicle suddenly began misfiring, lost power, and became completely inoperable, creating a severe driving hazard. Code P0301 indicates Cylinder 1 Misfire detected. A professional mechanic ran diagnostics and confirmed a permanent Cylinder 1 Misfire caused by internal engine failure. The internal heating was so severe it cracked the spark plug on cylinder 1 rendering the car inoperable at 72, 000 miles. The mechanic said evidence of moisture was detected in the chamber.

Purchased this vehicle in April of this year for my granddaughter. Check engine light came during test drive. Was told it needed some oil added and that took care of the issue. Soon after the check engine light continued so I made an appointment with auto mechanic. Code reads a misfire on 3rd cylinder with coolant leaking into cylinder. Extended warranty will not cover the $8k cost to replace engine. Ford knows of this issue. Many others do not understand why there isn't a recall on the engineering debacle. My granddaughter is pregnant and I'm worried about her driving this vehicle.
