Technical Service Bulletin TJ31602 9 3 2019 — 2019 VOLVO S90H

The customer may report that the infotainment system in the vehicle re-starts or reboots intermittently while driving. When this happens the CCD and the center area of the DIM will go blank for a few moments and then start back up as if the vehicle has just been started up. The customer may also notice that the infotainment system is not responding as normal (ex.- long response time) just before this occurs. When the system reboots, some customer settings may change back to a previous setting (ex.- navi destination, climate settings, radio station, etc.)
