The heads-up display, all warning signs and the instrument cluster showing the speed unpredictably goes off - sometimes comes back on right away, sometimes doesn't for hours. The car is available if needs to be reviewed. One cannot know the speed of the vehicle without the speedometer, warning signs turn on & off randomly impairing one to judge the actual warnings, the blind-spot cameras that usually are visible on the instrument cluster cannot be seen, the randomized turning off of the HUD and instrument cluster mid-drive causes a great deal of distraction to the driver. Three services done so far - in last one they found the associated codes with the issue but could not duplicate the case. Inspected by the manufacturer. No particular warning signs - happens randomly and all warning signs turn on randomly too without any actual warning.
