2018 Ford Fusion Engine

While operating my 2018 Ford Fusion, the vehicle began experiencing internal coolant loss resulting in engine misfires, rough running, and white exhaust smoke. The coolant intrusion caused engine failure and loss of reliability. This condition creates a safety risk, as it can lead to loss of power while driving, hesitation, and the possibility of engine shutdown. The defect occurred without warning and is consistent with widespread reports involving Ford EcoBoost engines. This issue is not related to maintenance or normal wear and tear but is a known design defect acknowledged through service bulletins and consumer litigation. Repair requires full engine replacement.

My car started rumbling and flashing the check engine light. I took it to the mechanic the next day, they tell me to contact Ford because of CSP 21N12 due to my spark plugs having coolant leaking on them and in cylinder, it was misfiring. They tell me the vehicle is unsafe to drive. I call Ford and they say theres nothing they can do. Im screwed out of a car because they closed the CSP's nov 2022 and i just got the car last year pre owned.

Engine replaced due to flaw in design. I had my 60,000-mile service done and after it was completed, I started having serious issues with my vehicle. Kept getting check engine light cylinder 2 misfire. I took my Fusion back to the dealership, and they advised me that my engine had to be replaced. Apparently when they put my vehicle under pressure during the service it caused the coolant to leak into my engine. I have researched this and found many complaints with the same problem. Unfortunately, the owners of the other Fusions (like me) found out their vehicle was no longer under warranty, and they had to foot the entire bill. Luckly for me, I had purchased the Ford Extended Warranty, and my out-pocket pocket is $100. I was told by the dealership that Ford is aware of this issue but has not issued a recall. My service advisor was absolutely shocked when Ford authorized the necessary repairs in a couple hours berceuse it normally takes a few days to get authorization. I have owned this car since it was new and have always kept up with the required maintenance. They gave me a rental vehicle and said it would be about 7 days before the repairs are completed.

Engine failure due to coolant leaking into cylinders. This is a known issue. Also Ford has issued a bulletin on this. but no recall yet! I still own 10k on my car and now a blown engine.

Vehicle has a loss of coolant but no visible leaks think may be due to a engine leak.

The engine cooling system and engine block failed due to coolant intrusion into the engine cylinders. This issue has been diagnosed by an independent mechanic and is available for inspection upon request. Yes, the problem has been confirmed by an independent service center, which diagnosed coolant intrusion into the engine block, a known issue on this engine. The shop recommended full engine replacement and stated this is a common failure in this vehicle. Not yet by the manufacturer, police, or insurance. The issue has only been inspected by a certified independent mechanic. Yes, a check engine light appeared along with a coolant temperature warning message. The vehicle also began to idle roughly, produce heavy exhaust, and consume coolant. These symptoms began appearing shortly before diagnosis in June 2025. I own a 2018 Ford Fusion with a 2.0L EcoBoost engine. The vehicle recently began experiencing coolant loss, heavy exhaust, and check engine alerts. A certified mechanic confirmed that coolant has intruded into the engine block, causing internal misfires and risk of major engine failure. I was told this is a common and well-documented issue with this engine design, yet there has been no official recall from Ford despite similar problems affecting other models (referenced in Ford TSB 19-2208). The mechanic has recommended a full engine replacement with an estimated cost of $13,000. This is a serious safety concern, as the engine can overheat, stall, or seize while driving.

2018 fusion AWD Titanium, less than 70,000 miles, no warning, no reason. Driving 70mph on interstate when low coolant light comes on, check engine light comes on, car starts losing power and running rough, finally full stall in middle of freeway with catastrophic engine failure due to coolant leak and faulty design. Car was not low on any fluids as they were checked everyday before it was driven. This could have gotten me and my children killed and quite frankly I dont know how it didn't. I bought this car with 44k miles on it. Drove it less than 30k miles and had catastrophic engine failure. This was AFTER I had it in the shop several times for crank shaft position sensor, wouldn't start, and several other problems. The car was taken care of and in immaculate condition. Ford knew these engines would fail prematurely and continued to manufacture them and sell them.
