Sensors that stop the car reversing if someone is behind them malfunction and you cannot reverse. Sensors that are meant to slow car for fwd collision do not work at all, or stay on with no obstruction causing you not to be able to drive. Dealer stated issue when temp is below 35 degrees and reset, issue not fixed. Nissan rep states no issues with car take to dealer. Multiple other people with issue on a group page. I hit a deer at 15mph the sensor never detected anything or stopped car. Nissan rep stated it was to stop.car for pedestrian not a deer.
