The error message is consistent, something about 'low auxiliary power'. I haven't checked the voltages myself, to be honest. Would that really point to a simple battery issue?

A consistent 'low auxiliary power' error definitely suggests a battery problem. Though a faulty charging system or a parasitic draw could also cause it. For peace of mind, I would visit the workshop.

Thanks! Turns out it was the auxiliary battery not charging correctly. Cost me 290€ to get it sorted. Appreciate the help!

Hmm, a weak battery and electrical malfunctions on a relatively new Traverse? Is the error message always the same, or does it change? Did you check the voltage of both the main and auxiliary batteries?
