Loss of Direction Control

What NHTSA is examining

On May 6, 2021, the Office of Defects Investigation (ODI) opened Engineering Analysis (EA21-001) to assess a sudden loss of steering control, in Model Year (MY) 2013-2015 Honda Accord vehicles. Consumers alleged while driving the steering wheel would pull to the left or the right independently. Steering pull may pose a risk of loss of directional control. Honda stated that they believed the inadvertent steering input was caused by a loose magnet located within the electronic power steering (EPS) system. Due to poor formulation of the adhesive, this magnet can become loose and move up to 2 degrees around the steering column. When the magnet moves, the torque sensor generates a signal that results in unwanted steering in either direction. Honda stated the steering force required to maintain directional control with a loose magnet is a maximum of 3-pound feet. The maximum force of the unwanted steering input can be overcome by the driver and is similar to driving on grooved pavement.The Vehicle Research Test Center (VRTC) sent over 4,000 questionnaires to 2013-2015 Honda Accord vehicle owners. Of the 637 responses, 58 consumers experienced unwanted steering. Consumers experiencing unwanted steering did not report difficulties maintaining directional control. There were no crashes or injuries reported to VRTC. Testing done by VRTC was not able to reproduce the allegations. Analysis of all relevant data indicates that the subject condition has a relatively low failure rate. The…
