Coolant is leaking into the head gasket of the 2014 Ford Fusion Hybrid similar to the other 2014 Ford Fusion cars (they have a recall on them for this issue). Upon calling the nearest Ford dealership, I was told that the recall did not apply to my vehicle, even though the same recall has been made for other 2014 Ford Fusions (just not the hybrid specifically). The safety of the driver and passengers in the car is at risk due to the coolant fluid mixing into the engine oil, eventually causing a blown head gasket and potentially engine failure. This problem was identified within minutes of getting a routine oil change, as coolant was found in the cap of the head gasket. The vehicle has not been inspected by the manufacturer, police, or insurance representatives. There were no warning signs. The car notified me when I needed to change my oil, but otherwise, no dash lights came on and no notifications were sent to the dash.

On cold startup, a significant amount of white exhaust is sometimes observed coming out of the tailpipes. The exhaust has a sweet aroma and after checking the coolant levels, it appears that the coolant levels have dropped and the exhaust smoke is being caused by a coolant intrusion into the engine block. No warning lights have been observed and it only happens about half of the time.

I was having issues with this vehicle sputtering a bit and the antifreeze was seeming to be disappearing. There were no visible leaks. I took it to the shop to have it looked at. The engine light was on and there was a code for a cylinder 3 misfire. Th mechanic diagnosed the vehicle and, upon removing the spark plugs, noticed they were fouled with what he said was antifreeze in the cylinder (because of the white substance on the electrode end). I saw where there is a recall for the particular engine block that is in this vehicle from 2014 to 2020. When I notified Ford and the NHTSA I was told that my VIN number was not included in the recall. I am confused because I would think that the recall would be for vehicles with this particular block not specific VIN numbers. Please help! I just got this car hoping for a reliable vehicle. I am a grad student and I do not have the funds for such a big repair.

Vehicle flexplate broke causing loss of power in rush hour traffic. Luckily was able to get to the side of the road without major incident or causing an accident. Broken flexplate also caused damage to transmission and ptu. Was informed this is a common issue wiith this yeat make and model but ford refuses to do anything about it. They would rather wait for some peopke to lose their life befor takiing responsibility. But who cares about peoples lives when you have stockholders to pay and ceo bonuses to hand out. Feel its worth mentioning i had the car at the dealership a couple times for other issues and had asked them about problems i suspected were precursors to this happening. They denied there was even an issue. They they told me the noises were normal and refused to even document my concerns let alone actually physically check the vehicle. I believe they were intentionally trying to hide the fact they knew exactly what was going on. Ford needs to take responsibility but since they wont you guys need to make them.

A third party hacked my CPU/Transmission Control System causing malfunction with the engine. The engine randomly would cut off during traffic, and I would need to press gas directly after starting the vehicle to go. My vehicle was fairly new and transmission module should not be ineffective after purchasing my vehicle last July 2023 with less than 80K miles. The notification that makes the vehicle stay in the lane would malfunction randomly notifying me of failure to sensor active crash alert. I also have inability to connect to Ford vehicle app with no reason provided to cut off WiFi connectivity. Please review external IP as I can hear communication of third party observing my way of driving and communication while attempting to drive causing distraction affecting safety of myself, my location placement, and health of the car. Possible CPU/transmission/AC connectivity from July 2023 to Malfunction of vehicle starting 10/2024.

I bought the 2014 Fusion in 2019 used. It had roughly 60 some thousand miles. I had to replace the motor at 94 thousand miles. Now at 131 thousand miles, I am faced with the same issue and need to replace the motor again after only 37 thousand miles. From what the dealer said (Copper Country Ford in Houghton Michigan) both issues have been coolant leaking into the cylinders and killing the motor. The first motor was around $4500.00 and now it is roughly the same $4500.00. So $9000.00 in 4 years!!!!! I called Fo Mo Co and they will do nothing to help. They say there is no recall and or order from NHTSA about this issue. Nor do they have any other programs to help resolve this issue or help pay for the repair. First Motor Replaced August 2020 at 94,000 Second Motor Died December 2024 at 131,000

The reasons for my Ford Fusion 1.5 to have been brought to the Premier Ford, Waveland, Ms was as follows: The temperature overheat lamp light was jared, there was 3 leaks from the overheat, there was a Shutter and sounds that came from the engine, (LIMP*)and there was no fuel power through acceleration. There had been moisture located on exhaust before brakedown without having been driven for approximately 10hrs before brakedown. 2ed service was as follows: temperature overheat lamp light jared, no power through fuel to accelerate, and issues starting. LIMP* I had not on this brakedown paid attention to if my Fusion needed water, the engines performance in regards to shakes or sounds nor did I look to notice nor did I look for leaks.
