Quite often blinker sound and audio system loss (IHU reboot) - jos - 07-25-2026
Hi,
since Volvo UX 5.0.5 and 5.1.17 i quite often have a loss of blinker and audio output which needs a IHU reboot or much worser in the night while driving reboot while everything goes dark for a while, if this just me or has anyone else similar problems? It doesn't matter of the car is on OEM or with changed config.
Best Regards JOS

Yes it is a known issue. We have had it with our MY25 XC90 and our MY24V60CC, both with 5. versions of the latest software. The IHU reboot normally returns the sound functions.

This hardly sucks, this happens to often for a such expensive car, hopefully some guys never testdrive this will be able to fix this with the telemetry data they catch from us all.
From where do you know that this a known issue and has this fixed in some way for you?
First it appeared with 5.0.5 after my config tunes, i was fast driving in polestar mode > 200 km/h and the IHU went off, first thought, i fucked up the car :-).
Well after this it happened again while driving in the city, also after parking, used the next day and from the start the IHU was off. So this happens in every Situation and it feels like a stupid sw bug.
Same with 5.1.17, hopefully the next update will stop this s***.
I know that the reboot returns the function to normal but the feeling is broken :-)

My Sensus car is not even able to sync the blinker sound with the blinkers. How hard can it be?
