My 2020 Volkswagen Arteon SEL has started shutting down the infotainment without warning and it can take up to 5 mins to restart. The strange part is it happened both with and without my iPhone connected, so I don't think bluetooth is the cause. A coworker told me he had a similar issue with his Passat but his would reset faster. Has anyone found if a software update helps or is this more likely a hardware fault?
