In the sring of this year, i lightly drove through a water filled pothole in a parking lot when all of the displays went dark for a split second and then came back on like the car had just started. I called my dealership right away and was told that maybe some water had gotten into some wiring and caused the glitch but to call again ASAP if it happened again. On Dec 9, 2021 under dry and even surfaces while making a left turn the vehicle went dark again while driving but this time took a touch longer to re-engage. I called the dealership again to report this to be looked at during a maintenance appointment. They found nothing wrong, but suggested it was a feature the car does not have was turned on and they turned it off.
