 The Tesla Model X faced criticism in 2016 for issues with the falcon-wing doors, which sometimes did not open or latch properly in some early production units, and the windows, which sometimes did not open or close all the way.Tesla addressed these issues with several software updates, and no known issues remained after the 8.0 firmware was released.On June 27, 2016, Tesla settled on a lawsuit over usability concerns, accepting that the Model X was rushed to production before it was ready, and by October 2016, Tesla claimed the problems had been reduced by 92%.
