NHTSA Complaint #11455413 — 2020 TOYOTA SUPRA

There was a beep and then my dashboard went completely blank (was just dark) so I couldn't see any information such as how many miles per hour I was driving or how much gas I had or my navigational information or what gear I was in. Then the dashboard came back on and it said there was reduced driver assitance (but did not say what was wrong). The dealer says my dashboard should not have gone blank but they can't fix it since not sure why. This is very dangerous and should be addressed.
