Nissan North America will be contacting the owners of certain 2014-2016 Infiniti Q50 and 2014-2016 Infiniti Q50 Hybrid‘s about a problem that could diminish the responsiveness of the steering. The vehicles affected are equipped with an optional DAS (steer-by-wire) system.
According to the defect report, a combination of low battery power at engine start up combined with a large steering angle, could cause an error in the steering ratio calculation algorithm. If this happens, the driver will notice the steering wheel off center , the VDC warning lamp will illuminate and there will be a noticeable change in steering responsiveness and turning radius. If the vehicle continues to be driven in this condition, it could increase the risk of an accident.
Those receiving notices are asked to return to their dealerships to have the Direct Adaptive Steering ECU software reprogrammed. Owners wanting more information about the problem are asked to contact Nissan customer service at 1-800-647-7261. The NHTSA campaign number is 16V-430.
