NHTSA COMPLAINT - 2017 Ford Fusion Energi Titanium (VIN: REDACTED) - [XXX] (Collision) Q1: FAILED COMPONENT Battery Energy Control Module (BECM) and hybrid battery cell balancing circuits failed post-collision. Per Ford Recall 23V-440, Current Interrupt Device causes excess voltage, fire risk, toxic gas exposure. DTCs: U1027 (ABS/ECM loss), P2450/P2451 (EVAP stuck open/closed), P0DD2/P0DD6/P0DDE (battery cell balancing circuits H/J/K/M stuck off). Vehicle available for inspection. Q2: SAFETY RISKS Sudden power loss, fire risk, CO/HF toxic gas exposure from damaged cells. HF IDLH 0.025 g/m³. Symptoms: headaches, cognitive issues, respiratory problems requiring Brain MRI. Ford documented 7 fires, 2 while driving. Gas events recur when changing charging amperage; CO detector alarmed repeatedly; hospitalized for symptoms. Q3: DEALER CONFIRMATION NOT investigated. No Ford dealer conducted required post-collision battery diagnostics despite DTCs proving multiple system failures. United Insurance Claims ignored [legal demand] for hybrid-specific inspections. No CO/HF assessment. Battery cell balancing failures indicate physical collision damage to high-voltage system. Q4: INSPECTIONS Insurance: Standard only, ignored DTCs requiring hybrid testing. Ford Service (Tempe, AZ) and Ford Collision Center (Mesa, AZ): No inspection; reasons given a) lack capability b) we just scan the vehicle; we don't thoroughly inspect for gas leaks". Recall 23V-440 documents identical failures. Police: No report (real-time audio capture of admission of at-fault driver), no hazmat assessment. Multiple permanent DTCs prove need for Ford-certified diagnostics. Q5: WARNING SYMPTOMS Pre-collision: Intermittent issues, check engine light, reduced range. Post-collision: Reduced range, Gas exposure symptoms plus DTCs U1027, P2450/P2451, P0DD2/P0DD6/P0DDE showing communication/battery cell failures. Medical documentation available. Pattern confirms BECM/battery damage per documented defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORM

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 contact owns a 2017 Ford Fusion. The contact stated that the check engine warning light was illuminated. The message to clean around the gas cap was displayed. The contact stated while driving 30 MPH, the vehicle made an abnormally loud sound and was vibrating. The contact pulled over to the side of the road. The contact noticed that the sound was coming from the fuel tank flap. The contact stated that while pushing the fuel tank flap, the contact felt a significant air pressure, and the failure ceased after the flap was closed; however, the failure recurred while the flap was not completely closed. Additionally, the contact stated that the vehicle was experiencing rough idling and the vehicle stalled while at a traffic light. The contact stated there was black smoke coming from the tailpipe. The vehicle was taken to Auto Zone, where it was diagnosed and determined that the EVAP system was leaking, and the EVAP canister control valve had failed and needed to be replaced. The dealer was notified of the failure. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 86,000.

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.

I am having a lot of problems with my transmission and torque converter and after some research I’ve seen those are both commonly recalled parts on the 2017 ford fusion. My car only has 67,000 miles on it and I believe it’s too soon for this to be a problem. When I try to accelerate from 2nd to 3rd gear my tachometer shoots up and my car will start doing a jerking motion and won’t accelerate

According to repair shop check engine light will remain on as anti freeze leaks due to a malfunction in my car. Repair shop states this is not a recall as it is not a safety issue and yet when I put on gas peddle car doesn't auto engage to proper speed. I also don't see how coolant leaking on engine wouldn't be safety issue.

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

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.

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.

1). 3 days after purchasing the vehicle I wasn't sure but I could tell that something was wrong so I called my husband and told him while driving the car that something was wrong and he needs to notify the dealership. 2). 5 days after purchasing the vehicle I went into a grocery store. When I came out the car was on/running, all by itself. 3). Additional problems occurring on a daily basis with the vehicle which lets me know that it's electrical problems are as follows: A. The vehicle randomly turns on and off all by itself, this is very hazardous. B). The headlights also randomly do not work while driving the car, day or night, which is very hazardous for both me and my clientele, as I am a Lyft driver. C). The interior lighting on the console and dashboard become dim or do not turn on at all, day or night. D). While driving the vehicle it does not always accelerate properly, which is very hazardous in traffic. E). The Bluetooth system connects and disconnects itself randomly. F). The air and heating system randomly turn on and off without being touched. G). Charging my phone in the vehicle is also challenging as it does not always work. H). Bluetooth radio stereo system is continuously problematic, volume randomly increases and decreases and turns on and off by itself, even with the vehicle completely shut down. I). After locking the doors, everything inside the car does not completely turn off. Interior lighting sometimes turns off and on separately, and it can take up to 30 minutes for the dashboard lighting to go off. J). The instrument panel often makes some sort of sound/noise and the gear shifter dial will aluminate even though the car is off/completely shut down. K). While driving, front windshield defogger will randomly turns on, causing the windshield to fog up, distorting vision, which is very hazardous. L). Dashboard vents emit an extreme amount of heat even though both heater and air conditioner are completely off.

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 gas tank does this sucking noise and it's been fixed once but it keeps having this same issue and cuts my car off. It takes 15 to 30 minutes before it starts up again. When I looked up the issue I noticed other for fusions had been having the same problems.

THE OWNER/MYSELF DRIVING VEHICLE HOME MY 2017 FORD FUSION SE 1.5L ON THE INTERSTATE WHEN WHITE SMOKE BILLOWED OUT FROM THE EXHAUST LEADING TO A SEIZED ENGINE ON A HIGH TRAFFIC DENSITY HIGHWAY. THE CAR STARTED TO SPUTTER, CLUNK AND THE CHECK ENGINE LIGHT KEPT FLASHING AS I PULLED OFF THE SIDE OF THE ROAD. THIS CAR HAD ISSUES BEFORE THE FAILURE OF THE ENGINE WITH CYLINDERS MISFIRING, SPARK PLUGS BEING FOULED AT LOW MILEAGE AND ENGINE LOSING COOLANT. PER MY VEHICLES BREAKDOWN I BROUGHT IT TO A LOCAL MECHANIC WHO WORKED FOR FORD AND STATED MY ENGINE LOCKED UP AND NEEDS TO BE REPLACED, AFTER BRINGING MY CAR TO ANOTHER SHOP FOR A SECOND DIAGNOSIS, IT WAS THE SAME ANSWER AFTER A FULL LOOK AT IT. I TRIED CALLING FORD IN MICHIGAN THEY GAVE ME THE RUN AROUND, MY DEALER FRED BEANS OF FORD GAVE ME THE RUN AROUND SAYING I HAVE TO COVER THIS REPAIR DUE TO IT BEING OUT OF MY WARRANTY. I DID THE PROGRAM 19B37 RECALL FROM FORD WHICH RESET THE COMPUTER SYSTEM FOR ANTIFREEZE AND COOLANT ENTERING THE ENGINE. CLEARLY, THAT ISSUE THAT FORD TRIED TO PATCH UP DIDN'T WORK. MY MECHANIC & FORD DETERMINED THAT A NEW ENGINE WAS NEEDED AND HAVE FOUND BULLETINS STATING THIS IS DUE TO A MANUFACTURING DEFECT KNOWN BY FORD AS FORD HAD RELEASED THE BULLETINS. THIS DEFECT LEADS TO ENGINE FAILURE AND IS NOTHING CAUSED BY THE DRIVER BUT SOLELY DUE TO THE FACT THAT WHEN CERTAIN ENGINES WERE MANUFACTURED THEY WERE MANUFACTURED INCORRECTLY. FORD IS UNWILLING TO PAY FOR ENGINE REPLACEMENT EVEN THOUGH THEY HAVE ADMITTED THIS IS FAULT DURING THE MANUFACTURING PROCESSES IF THE ENGINE IS TO STALL OR SEIZE DURING DRIVING THIS COULD LEAD TO SERIOUS INJURY, ACCIDENT, AND EVEN DEATH. FORD IS NOT RECALLING THIS ENGINE AT THIS TIME. PLEASE - RECALL THIS ISSUE. 1.5 & 2.0 ENGINES ARE VERY PROBLEMATIC. THE COST FOR MY REPAIR IS $4,800.00 THAT I DON'T HAVE.
