NHTSA Complaint #11705850 — 2014 HONDA ACCORD

​1. What component or system failed? ​The ABS/VSA Modulator Control Unit (also known as the ABS pump or module). This system is responsible for Anti-lock Braking and Vehicle Stability Assist. ​2. How was safety put at risk? ​The failure often results in the complete loss of Anti-lock Braking (ABS) and Stability Control (VSA). ​Increased Stopping Distance: In emergency braking situations, the wheels can lock up, leading to skidding and significantly longer distances to stop. ​Loss of Steering Control: Without VSA, the vehicle is prone to "plowing" (understeer) or spinning out (oversteer) during evasive maneuvers or on slippery surfaces (rain, snow, gravel). ​Brake Pedal Issues: Some owners report a "hard" or "unresponsive" brake pedal during the moment of failure, which causes a delay in braking response. This is a widely confirmed issue for 9th Gen Accords. ​Dealer Diagnosis: Most owners have this confirmed by a dealer through Diagnostic Trouble Codes (DTCs). Common codes include 121-11 (VSA Solenoid Malfunction) or 81-20 (Acceleration Sensor Malfunction). ​Service Centers: Independent shops frequently see this issue and often recommend third-party rebuild services (like Module Master or UpFix) because the OEM replacement part from Honda is expensive ($1,500–$2,500) and frequently on backorder. ​4. Has the vehicle or component been inspected? ​Manufacturer: While Honda has not issued a widespread safety recall for the 9th Gen module specifically (unlike the 2023 "Brake Hold" recall), many individual units have been inspected by dealer technicians. ​ 5. Were there warning symptoms? ​The symptoms usually appear suddenly and without prior warning, often referred to as a "Christmas Tree" dash. ​Warning Lamps: The ABS, VSA (triangle with exclamation), Traction Control, and sometimes the Electric Power Steering (EPS) and TPMS lights all illuminate simultaneously.
