“An unknown number of Lexus automobiles have seen their infotainment and navigation head units broken by a bug in an over-the-air software update from Lexus.
The glitch, which was confirmed by a Lexus spokesperson, was delivered in a routine software update. In affected cars, it can cause the dashboard screen to spontaneously reset itself and, as a result, both the radio and navigation system can be unusable. It affects cars equipped with Lexus’ Enform system with navigation.”
