My 2016 Ford Fusion check engine light came on and started blowing white smoke out of the exhaust. I had it towed to the Ford dealership and they told me that my entire engine needs to be replaced because of a coolant link on the engine. They said my car overheated and had no coolant. I know my engine had coolant and there was no sign of a leak. There was no notification of the car overheating. After researching on the internet there is a known part that cause this problem. Ford is aware and they aren't fixing it. My car could have caught on fire with no fault of my own. I can't afford to pay $10,000 for a new engine. This is an extreme financial hardship for me.

First noted engine acting sluggish about a week prior to 2-13-24 oil change at Firestone. They suggested it may be the fuel injection system needing to be cleaned, which they performed on 2-14-24. Engine continued to run sluggish and was in fact worse than before, engine light came on 2-21-24 so Firestone replaced fuel injector that day. Error codes were reading misfire in cylinder 2, the engine was still full of carbon and other buildup so they thought there was still residue and thoroughly cleaned everything again after replacing fuel injector. On 2-22-24 I refueled after work and car would not start. AAA was dispatched to tow vehicle and I notified Firestone it would be brought in, fortunately after about 15 minutes I was able to start it and drive it to Firestone, engine light immediately came on. They looked at it first thing on 2-23-24 and engine started up normally, they suspected a faulty fuel canister valve (which was replaced in 2020) but that did not turn out to be the case, codes were again reading misfire in cylinder 2. White smoke began emitting from exhaust and they discovered spark plugs as well as engine cylinders were soaked with oil, also coolant was nearly gone despite no signs of a leak. Upon doing research they discovered this website and pending class action lawsuits against Ford for faulty engine design that knowingly causes coolant to leak into cylinders, thus causing engine block to fail. They advised me to trade/sell the car immediately but also to have Ford give their opinion. AAA towed the car to Sarasota Ford on 2-28-24 and they called on 3-1-24 to report the engine had completely failed and it would cost $12,000 to replace. I declined and will arrange for AAA to tow it home until we can sell the vehicle for scrap per advisor's suggestion as it cannot be traded or sold in this condition. I have spent thousands in repairs/Ubers as Ford refuses to cover cost or provide a loaner, also had to open Firestone credit card just to cover repairs

My vehicle has been maintained by the dealer and myself for the 87800 miles that have been put on it. I purchased the vehicle in August of 2016 brand new with 34 miles on it. The motor has a manufacturing defect, the block was built in the same plant (Hermosillo, HERMOSILLO, MEXICO)that other Ecoboost motors were built in that were recalled for the coolant leaking into cylinders via a "fix" which was cutting a channel between the cylinders on the deck of the long block between the cylinder walls, this compromised the integrity of the seal between the cylinder head and head gasket. This allowed coolant to leak into cylinder 4 of my vehicle. Ford has known about the issue for the last several years and continues to make these motors. The dealer I purchased the vehicle from wants $14,000 to replace the motor with a new long block but I would not feel comfortable having that done and would want a crate engine as the other components would now be compromised. I have spent $1200 on replacement coil packs and spark plugs, coolant and oil, all to treat the symptoms. In addition to Fords $260 diagnostic fee at the dealer for a known defect. Ford should not get away with bilking customers for $10,000 plus engine rebuilds - this would likely not last the same miles it has gone currently in my case.

A couple days before scheduled tune-up, noticed that 2016 Ford Fusion(Ecoboost), began to drive differently. Exactly one day prior to service appt. the check engine icon appeared. Long and short, dealership reached out after me leaving car to explain that my 7 yr. old vehicle with regular maintenance, just over 100,000 miles, and no prior issues could not receive a regular maintenance tune-up due to spark plug(s) being wet from leaking coolant and an engine replacement being the only option of repair. Although, I was told at the time and read that this habitual issue was common in my make and model, there were no recalls in place to rectify the issue. Safety at risk based on other Googled reviews and articles with the same known issue with consequences ranging from low coolant to possible total engine shut down or fire. It was those reviews with similar diagnosis and recommendations that led me to this site.
