Either closing the moonroof or the wipers activating caused the screen to flicker off and back on. Sustained usage or frequent usage caused the screen to completely deactivate for 10+ minutes and the Driver's HUD to deactivate and retract. During this time, the car was operating on the highway in rain conditions with zero driver's instrumentation, including speed, navigation, fuel, battery, safety warnings, blinkers, or other indicators. It was unclear if blind spot indicators or driving assistance features were impacted, or if vehicle lights were impacted as no indicators were present in the vehicle. This incident lead to driver anxiety, reduced situational awareness, reduced confidence in the vehicle's safety and operational capability, and reduced safety to other vehicles around the car as it could have led to changes in driver behavior or lane changes due to surprise at vehicle behavior.  The problem has been reproduced by the dealership's service station, however the dealership has changed ownership recently and has lost some records.  The car has been in dealer service for the past 70 days but the fault is still not understood or remedied. The dealership was made aware of this roughly 60 days ago and is resisting even replacing the vehicle, let alone understanding and remedying the quality issue.
