Arkana Transport Mode Active

Transport mode being active usually indicates a setting that limits certain functions for delivery. Have you checked the vehicle settings menu to see if you can disable it? Have you tried starting the car with the spare key fob?

I've reviewed the vehicle settings; there's no option to disable transport mode. The spare key fob produces the same result. Is a diagnostic check the next logical step?

Yes, a diagnostic check would be the next logical step. It is likely that the vehicle needs to be reset by a workshop using Renault diagnostic tools.

Confirmed. The Renault workshop reset the transport mode. Apparently, a software glitch caused it to activate spontaneously. No charge for the fix.
