Verbatim from NHTSA complaints, newest first
“If i do not run my car for atleast 10 minutes before driving, my gas tank will start making a loud horn sound, and when this happens and i go to slow down, the car will shut off. Mechanics say there’s an issue with the purge valve and the charcoal filter. I’ve already had this issue fixed three times and it comes back less than a week prior to service”
“Have had to replace the same 2 coil pacs in last three months. Car will not accelerate properly will not shift into gears properly took to have information test done keeps coming back fouled 2 & 4 coils”
“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.…”
“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.”
“Just got my car I’m financing (used) It’s been giving me problems since I got it slow acceleration, overheat . , engine stalling Start and go Option isn’t working . Can I have a professional assist me with a recall maintenance please”
“I believe my 2017 ford fusion should be included in the recall for the BECM for the 2019-2020 because my charging port has a sticker with QR code and ( CD391 PHEV ) and I keep having intermittent problems with the Battery Energy Control Module”
