There is coolant slowly leaking into cylinders. I am having to put antifreeze in reservoir every other month. I am afraid it will ruin engine or catch on fire.

The engine codes stated that cylinder 3 was misfiring, and all of the spark plugs were replaced. The check engine light went off for a few days and then came on with the same code. Then all of the coil packs were replaced. A few days later the engine light "coolant overheating" came on and the engine started running rough, the computer stated that it was shutting the car down to half power. There were visible signs of coolant sprayed all over the engine. After allowing the car to cool off for 2 hours the car continued to run rough and display coolant overheating. The car was unable to reverse but could go forward. The car was taken to a mechanic and cooling issue codes came up. The cooling system was tested and the water pump was checked before the coolant was found to be leaking into cylinder 3. The car was not repaired, as this is the second engine for this car with approximately 130,000 miles.

Coolant leak into my short block engine

- Fort Mill, SC, USA

A flaw in design allows coolant intrusion into the cylinders ruining the engine and requiring engine replacement. TSBs have been issued on this problem which is caused by a flaw in the design. The car drove fine Monday morning, 9/19/2022 On Monday evening, driving 80 mph, (which is the speed limit on the 130 Toll Road), the car suddenly started shaking, slowed and did not want to accelerate and the check engine light started flashing. The car was checked with OBD reader, error code P0302, a misfire in cylinder 2. The next morning, 9/20/2022, after confirming with Ford service that it would be ok drive, drove 5.5 miles to dealership, with the car shaking, vibrating & check engine light flashing. On 9/22/2022 we were told the engine needed to be replaced at a cost of about $11,000. After researching online, I found there is a known design flaw on the Ecoboost engines that allows the intrusion of coolant into the cylinder and the only repair is engine replacement. Ford has been aware of the flaw in design on the Ecoboost engines for years but continued to manufacture and sell them putting peoples lives in danger by selling a car that can suddenly lose power, vibrate violently and possibly catch on fire if it overheats. There is a Customer Satisfaction Program 21N21 covering the short block on 2017-2019 Ford Fusion Ecoboost cars but nothing on prior years. Per a Ford Customer Experience Specialist I was informed that financial assistance on my car ended at 7 years or 150,000 miles; any assistance they could have offered ended on 9/14/2022; 6 days prior to the incident. I was informed that how Ford determines financial assistance is proprietary and no further explanation could be given.. I understand the car is 8 years old; however, a well-built car with low mileage (53,590) should not need a new engine. What happened to Ford -??Built to Last?-?? Ford needs to stand behind their products and do the right thing by covering the costs of repair due to a design flaw.

Had check engine light code P0302 #2 cylinder misfire. Took into ford dealer for diagnosis. Problem was coolant intrusion into #2 cylinder due to engine design. Recommended engine change. 2015 1.5L ecoboost.

Ford has been putting this Eco Boost engine in their cars for a very long time. They are two class action suits about this particular engine and that it leaks coolant into the engine. NO ONE told any of us consumers about this problem. In fact they put out service bulletins to the dealers but we were never told anything about it. You are also putting this problem into an engine category when most of those claims are specifically for this problem (11 is what you state but you need to look at your 184). I am alerting all the complaints about this to file a claim about this very situation. This is truly shameful. You have a co. profiting over the consumer and no one is doing anything about the engine problem. We are now told the car needs a new engine at the tune of 8000+ dollars and honestly no one can even tell us when the parts are available! We could have made a more educated decision had we been told. 2) 1.6L EcoBoost Overheating Issues There-??s a lot to unpack when it comes to problems with the Ford 1.6 EcoBoost engines overheating. There have been several lawsuits, service bulletins, and recalls related to overheating problems. In 2017, Ford issued a recall for some 2014 Escape, 2014-2015 Fiesta ST, and 2013-2014 Fusion models. The main issue seems to be running low on coolant, which causes the cylinder head to overheat, crack and leak oil. Some even ran into fires due to high pressure oil leaks. Ford added coolant level sensors as part of the recall. As of recently, there is a lawsuit that claims the Ford 1.6 EcoBoost has an inherent flaw. It alleges coolant leaks into the cylinders thereby causing corrosion, engine failures, and possibly even fires. We-??ll leave it at that since there-??s quite a bit of info out there regarding the recalls, service bulletins, etc.

Spotted another puddle under the car. Took to local shop & told left front caliper is leaking and both front calipers need to be replaced. Also told the cooling line to turbo is leaking & needs to get repaired. Having vehicle towed to dealer as unsafe to drive. When I drove vehicle back from shop, low brake fluid light finally came on. I have also had both brakes lines replaced twice in the last 5 years & transmission replaced. Believe this car may be a lemon.

While I was driving home from work my car shortly turned off while I was on the freeway. Luckily it turned back on in time that nothing happened. A couple days later while driving home from work my car started violently shaking while driving since then I did not drive the car and took it to a mechanic for inspection. Soon inspection they found a Cylinder #2 misfire resulting in the need to replace entire engine. Car has 67,000 miles and has been kept in great condition. There is no reason for the engine to be breaking at 67,000 miles. I will now be paying about $8,000 for a new engine on a car that originally cost me $12,000. I have only had this car for 3 years. I am aware that the 2016 model of my car had a recall on the engine for a similar issue and I believe the 2015 should be recalled as well. Not only is a faulty engine a huge expense for the owner, it-??s also a huge safety concern for the driver and other drivers on the road.
