Electric traction system fault

DS Automobiles DS 7 & DS 7 CROSSBACK

Hello,

Today I had warning on my dashboard “Electric traction system fault:repair the vehicle”
It is the second time.First was a couple of weeks ago.
Been advised by RAC mechanic that I need software update.
After turning vehicle off and on again the message dissapeared and the car drives normaly.
Any thoughts?

Thanks
