I updated the maps in the car's navigation system on 8/3/2016. At that time, Volvo's server in sweden were down. They had been down for days. Next morning, when I started driving to work, I noticed that the sensus system started rebooting every couple of minutes. As I drove on the highway, I noticed that when the sensus system rebooted, if my left turn signal was on, it would go off for a couple of seconds and then come back on. If the sensus system was rebooting and I tried to turn on the left turn signal, it would not come on. This is a safety issue as sensus system is just a central console and it's reboot should not impact car's basic functions. By the time I left work in the evening, the server in sweden was back online and the sensus console stopped rebooting and issue never happened.
