There is a recall on 2017 Ford Fusion's torque converter. I currently have a 2017 Ford Fusion. After inspection at a Ford service dealership, the "torque converter clutch internally failed filling the transmission filter with metal debris and starving the pump for fluid causing debris to go throughout the transmission." The problem with this, is that even though it's list as a recall for ,y specific car, the recall is not listed under my VIN number. This inspection was done on December 17, 2024. The safety of myself and children were put at risk when my car hesitated to accelerate on multiple occurrences on busy roads and intersections. The problem has been reproduced by a Ford dealer and has also been inspected by a Ford service dealership. There were no warning lights on indicating that there was a problem.
My brakes are grinding squealing/rattling and i have pads replaced, no rotor wear, not sure what's wrong. I've brought my car in to be serviced 3+ times and have left with no fixed car and worse brakes. When i bring up issues with my car that are related to the recalls the car has, they tell me those recalls don't apply to my car although im having the same problems. My brakes have progressively gotten worse/louder and the pressure on my pedals is not the same. I'm scared to drive my car and i have been trying to get it fixed for months. This is not the only problem im having, my gas tank "farts" constantly and my car will stall and shut off unless i turn off auto start stop. There is no recall on this yet it's a KNOWN problem. It makes the car undriveable.

The temp gauge suddenly jumped up and alert said coolant was low. Driving on freeway, car shut down before I could get into a shoulder. Big rigs swerving around me, could have been killed. No leaks under car. Cap off the coolant reservoir and the coolant level bubbles up back to normal. After that, even driving one mile makes the temp gauge jump up and drop down erratically. Quoted more thank $8,000 to repair because it requires a new engine? Ford dealership said this is very common issue for Ford Fusions, that it is a design flaw and many of their clients have had similar safety scares.
The antifreeze leaks into the engine due to a KNOWN manufacturer design flaw, is available to inspection upon request and appointment made. Mine and others safety are at risk due to the fact that if the engine seizes up while driving, could lead to a sudden crash. Problem confirmed by a local mechanic. Not been inspected by anyone else other than a different independent mechanic. The first sign of a problem is a check engine light, followed by a sputter in the engine and lack of consistent speed control, first appeared in February, and lead to 2 sets of spark plugs being replaced
All right, so I have a little bit of bad news for you, so we hooked up a code reader to the car. And there were a couple of misfires. So there's a cylinder to misfire a cylinder or a random misfire detected, a cylinder 3, misfire a cylinder one misfire. So our service advisor thinks that it's probably not an issue with a coolant. An issue with the head gasket, and he would recommend that that gets replaced. And he said, at some point, you might need to replace the entire engine.
My vehicle is displaying severe symptoms as well as throwing code of the already noted recall for other trims of this car but my car isn't on recall list. I've had to replace the canister purge valve 3 times in less than 2 years, the vacuum seal is affecting fuel tank and honking every 15-20 seconds...when canister gets stuck open, I can't start my car which happened yesterday in a busy intersection. It's dangerous and I'm afraid to transport my kids in my car.
I went to my dealership because of a check engine light. After many hours of searching, I was told that a coolant leak had been found. I was informed that the head gasket was damaged and causing a leak into the engine. The cheapest repair would cost nearly $8000. The extended warranty that I purchased for the car has expired. Searching Google, I see that Ford is aware of the problem, and has known about it for some time. Ford should not be able to get away with this.
