Coolant Intrusion I bought the 2016 Ford Fusion 1/8/2022. Three days into ownership, check engine light came on. Ed Morse Ford of Lebanon, MO diagnosed the car and determined "Coolant Intrusion". Due to the flawed design of the engines small block, coolant was allowed to enter into the pistons and sparks plugs. Result of the coolant intruding into the engine components, the engine was getting excessively hot and at serious risk of catching on fire and major component malfunctioning. Ed Morse Ford at their cost, did replace the engine small block and updated some seals and belts. Dealership reported the newly updated small block design was installed. The new design removes the pin holes from the top of the small block moving below the surface. Original design is a fire bomb waiting to happen and has happened.
2016 Ford Fusion engine complaints
Page 13 of 19: complaints 341 to 370 of 536, newest first, as owners wrote them.
Engine is leaking coolant into the second cylinder and Ford did a full tube up and did not resolve the issue but is now saying the only course of resolution is a $10,000 engine replacement. The car randomly loses power and may cut off and is a hazard to drive on highways as the power will suddenly be cut. I’ve gone online to see numerous complaints and even the Ford dealer advised this is a common issue but refuse to offer any solution or work with me as I’ve only had the car less than 2 years as the owner but am now being told what they believed to be bad spark plugs is an engine cylinder filling with coolant and they are unwilling to do any repair knowing the engine quality is as bad to begin with and opting to replace the engine for quite and expensive cost that essentially is comparable to going and buying a used car for an issue that is apparently common for their ecoboost engines.
Bad coolant leak into cylinders from inadequate head gasket causing performance issues and needing major repairs. Engine was pressure tested and failed with loss of 5psi in 10 minutes.
My son was driving home from work and his engine overheated setting off steam and displaying red warning icon. He pulled over to side of interstate which happened three times from his work to independent car repair service. Blessed he was not hit sitting on side of interstate or that engine didn't lock up potentially causing loss of control. Both of these issues would have put my son at risk of death or bodily injuries. Both Independent Car Service and Ford Dealership confirmed failure caused by engine head gasket flange design flaw allowing coolant into cylinder head. This resulted in having to have the engine replaced which Ford declined to cover. Ford has recently changed this flawed head gasket flange design to prevent coolant from entering cylinders. It's difficult for me to understand why Ford or the federal safety agency hasn't taken action on this issue that can potentially put lives at risk. There are multiple years of Ford Vehicle platforms and engines that have this same faulty design. I have multiple children driving and I will make sure not to put them in a vehicle that puts them in potential harm. Regards
I had a check engine light appear on the dash. I took the vehicle to AutoZone to have the warning read. The reading came back as a misfiring spark plug. I had an appointment to get the spark plugs changed during my next oil change. A few days after I had the engine light read, the check engine light turned off. It was off for 1-2 days and then came back on. A few days later, while I was driving, I had a warning light that the vehicle was overheating. I pulled over and checked the coolant and the reservoir was empty. There were no signs of leaking coolant (externally). I let the vehicle cool and added coolant. At this point, I tried to start the vehicle and the vehicle wouldn't start. I had the vehicle towed to an independent mechanic to have it looked at. They indicated that the coolant was leaking into the engine and recommended having the vehicle towed to Ford for a detailed diagnosis. Ford diagnosed the vehicle and indicated that the engine needed to be replaced. All within a span of 10 days.
This engine needs to be recalled. Ford shame on you. You know there is a problem with the coolant and by not taking care of the people who were deceived in buying your vehicle is so horrible
On February 20, 2022 I was driving down a busy road when my car out of nowhere just started jerking and would not accelerate. I was stuck in the middle of the road while cars had to slam on breaks and go around me. My car would not move. I had to then turn my car off and restart it in order to get it to a parking lot for safety. I didn't have, and still don't have any warning lights on the dashboard that indicated anything was wrong or going on with my vehicle. I had to have it towed to my mechanic who confirmed my transmission was "shot". It was done. I have always kept up on maintenance and oil changes on my car.
Check engine light came on but no symptoms at that point. Mechanic pulled codes and replaced plugs. Car started skipping and starting harder, so brought in again. Replaced coil on cyl 4. And also used fuel cleaner in case fuel injector was clogged. Still no change except that the heat was not working. After a week or so. Called mechanic who said it sounded like coolant may be low so filled it and made appt. To replace fuel injector. Replaced that and noticed that coolant was low again. Star still skipping and starting hard. Brought it back and he mentioned coolant may be leaking into cylinder and they’d check if gasket blown/cracked. I expressed frustration and asked if I should bring to Ford. He said yes and actually reimbursed me $638. I made appt at Ford but they were a month out. Then I brought to friends mechanic and told him story and he determined it was definitely leaking into cylinder and likely will need new engine. Told me about TSB and all the complaints. Said I should bring to Ford to do work in case recall is issued and I’d get reimbursed.
Coolant leak into cylinder 3 due to defective 2.0L Ecoboost engine. Requires complete engine replacement.
Common issue with 2.0 ecoboost engines, coolant is leaking into cylinders. Caused engine to over heat causing a possible fire issue. There were no signs other than engine started to run rough. Vehicle still runs but smokes out exhaust.
The contact owns a 2016 Ford Fusion. The contact stated that while she was stopped at a red light, the vehicle temporarily shuddered and stalled. There were no warning lights illuminated. The check engine warning light illuminated. The contact was able to continue to drive the vehicle. The contact also stated that she saw smoke coming out of the exhaust of the vehicle. The vehicle was taken to the dealer who diagnosed that the short block needed to be replaced due to a coolant leak. The manufacturer was notified of the failure and informed the contact that they would assist with the repair of the vehicle. The contact was awaiting a call back from the manufacturer. The vehicle was not repaired. The approximate failure mileage was 70,000.
Purchased a 2016 Ford Fusion SE in July of 2021. First week I had the car the engine didnt crank/start. Took it to the dealership that I bought it from they sent me to their mechanic and was told nothing was wrong with it. Happened the third week of purchase went back to the dealership and was told to use my warranty and to take it to Ford. Took it to Ford and was told it had high resistance in my negative terminal in the battery. (First attempt August 2021) I was charged $400 to get the corrosion clean and put a coat on the terminal for protection. A week later my engine didnt start again. Had this problem for several weeks,one day the engine would start the next it wouldnt. I called Ford and was told to bring it back. (Second attempt Oct 2021) Ford told me they diagnosed the car and didnt find any codes to lead to the problem. Kept telling me the engine was starting when they had it but when i went to pick it up it wouldnt for me. (Third attempt Nov 2021) Went picked my car up from Ford on a Monday morning because it was ready and that they still didnt find anything wrong with it and it was starting up just fine. Leaving from work Monday night engine didnt start had to get it towed again to Ford Tuesday morning. I have called Ford headquarters to file a complaint. Do not purchase a Fusion they are terrible cars and Ford theirselves cant even find out what the issue is with the vehicle.
As with all other ford 2.0l Ecoboost engine. There apparently is a design flaw causing coolant intrusion into the cylinders. Which would require a new engine per Ford.
I have a 2016 Ford Fusion SE 2.0L. Got a P0303 code for a cylinder 3 misfire. The spark plugs and coils were replaced to no resolve. Still getting a P0303 code. Short term fuel trims are good so I dont think its an injector issue. The car began to over heat with out warning about a week after the P0303 code started presenting itself. This is dangerous as the vehicle could catch fire.
Defect in engine design allowed coolant to leak into cylinder. There have been recalls on the 1.6L and 2.0L ecoboost engines but not the 1.5L for the same issue. I was advised that his could cause the engine to misfire and overheat possibly causing a fire. A quick search revealed several incremental TSB, 21-2269 is the latest, regarding this issue. This happened with approx 57,000 miles and 5 years 6 months on the car. The only fix was a complete engine swap.
Engine light came on after car overheated. Took car into local auto service center and was told I had a blown head gasket. I'm filling this complaint due to the numerous other complaints regarding this same issue on the same year make and model of my car. Had I not taken my car to the service center immediately, potential for safety issue could have been high and impacted myself, family, and other individuals driving near me.
The contact owns a 2016 Ford Fusion. The contact stated that while driving at 35 MPH, a message stating that the engine was experiencing high temperatures illuminated on the instrument panel. The contact continued to drive the vehicle since he was approaching his residence. As the contact arrived at his residence, he opened the hood of the vehicle and noticed that there was no engine coolant; however, there was no evident coolant leak. The dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed or repaired. The approximate failure mileage was 52,000.
TSB 19-2346 needs to include 2016 models of the Ford Fusion. My wife was starting our 2016 Ford Fusion 2.0l EcoBoost when it started shaking violently in idle. The check engine light began flashing. We had it towed into Ford where they are now quoting us a $10,000 full engine replacement for “coolant in the cylinders.” This is the exact same problem the 2017-19 fusions are experiencing, so I am not sure why the 2016 isn’t on this list.
Coolant leaking into Engine
The car is missing on cylinder #1 and showing signs of a blown head gasket. Car will stall at random times as well. This is car has a the 1.5 ecoboost with a flway in the block design. Ford told me because of the flaw that I would have to purchase a new engine. There is currently a TSB out for this exact reason, yet ford wants me to pay for their mistake.
I have a 2016 Fusion with a 1.5 L EcoBoost, 54,000 miles on it. I am out of warranty by less than a year. My car told me that the engine was overheating while I was driving down the highway. I pulled off the road, and found there was no coolant in the reservoir. I filled the coolant up and kept an eye on it while scheduling a repair appointment. Every time I would drive the car, it would stutter when accelerating, only when it was cold. Once it warmed up it was not an issue. Every time I would also have to refill the coolant. I took the vehicle in, and found out it was misfiring on cylinder 4, and the coolant was leaking into the engine. Since it is out of warranty, it is $3,000 out of pocket. My car could have started on fire, or started smoking from the engine and caused a major accident had this gone on for too long. The misfire of the cylinder did not cause any warning lights to go on in my car. It would throw a code for a little bit, then disappear, it was a soft code not a hard code.
In September 2021 my 2016 Ford Fusion that has a 1.5L Eco boost engine had white smoke emitting from the exhaust. A check engine light came on and a test revealed that the #3 spark plug or ignition coil as bad. I had all spark plugs and ignition coils replaced. The light went off and three days later the check engine light came back on. We took it to Bob Tomes Ford 950 S Central Expy, McKinney, TX 75072. A Service inspection revealed that engine coolant was leaking into the cylinders and could potentially cause engine over heating and possibly a fire. This has been a known problem and numerous Service Bulletins (TECHNICAL SERVICE BULLETIN 1.5L EcoBoost - Low Coolant, White Exhaust Smoke And/Or Illuminated MIL - Built On Or Before 06-Apr-2019 19-2139) have been released on this issue, A compete engine replacement is the only repair option due to the original engine design since 2010 was a defective design which Ford actually recalled in the 1.6L engine but not the 1.5L. Ford Motor Company requires the consumer to bare the cost of repairs. My vehicle warranty was out by 2 months when this problem started at 82,000 miles. There is currently a law suit filed for this issue in U.S District Court for the Eastern District of California, Case # 2-2021cv00468. filed March 15, 2021.
Water seeping into cylinders causing engine warning light, missing, stalling and lost horsepower. Problem was found upon Dealership doing a pressure test and removing spark plugs to see the issue and confirmed. Water loss was being noticed during oil changes couple years before this incident. Last oil change 1200 miles ago noticed a big loss of water in the reservoir. First warning light appear 2 months ago but cleared a couple days later until this last warning light a week ago with noticeable performance issue.
Internal coolant leak inside cylinder causing misfire told engine could catch fire
The engine block failed, cracking, causing coolant to leak into the number 3 cylinder. Causing a misfire code. I could hear what sounded like water flowing behind the dash for awhile. Eventually noticed I was a little low on coolant, then ended up using a whole gallon of coolant in about a week. The dipstick also had coolant on it when I checked the oil level. The car has been at the shop since January 23rd, 2021, they tested the head and it was fine. When I noticed it was a serious issue, coolant was blowing out the tail pipes in white clouds. I have a short video of this happening.
Vehicle is not cooling off
Coolant leaked into engine causing cylinder 2 misfire and is now requiring an 8 thousand dollar repair for the whole engine.
Coolant is leaking into one of the cylinders which requires a full engine rebuild.
My fusion has had a rough idle when starting for the past year. I took it in to the mechanic and they said the problem was due to a backfire. They replaced the spark plugs and coils for around $500-$600. About 5 months later, I get e check engine light and a warning that the engine is overheating. Take it to the mechanic, where they figured out that this consistent issue is due to a head gasket leak, where coolant is going into the engine. From doing research, I have noticed that Ford Fusions with an eco boost engine have a poor engine manufacture and that this issue is prevalent in most eco boost engines. The new fix seems to be ranging from $1,200, and I have tried to diagnose this issue multiple times. This isn't easily distinguished by the engine warning, and can run the risk of drivers driving with lower amounts of engine coolant. If the engine overheats it can make the engine catch on fire. Although this did not happen to me yet, it has been months to diagnose this issue, only to find out that it is due to the engine model, and that leaving it untreated can cause serious damage to me and the engine.
Vehicle overheats. Filled up coolant reservoir twice in one week. Checked coolant, coolant low, no leaks, no water going into the oil, coolant evaporates and causes car to overheat.
