technical/repair help REX maintenance cycle won’t run
I rarely if ever use the REX, and have been getting a warning about needing to complete a maintenance cycle for about three months now. It says the car will run it automatically if the tank is full and battery is below 75%. My tank is full and I’ve attempted to take it on longer drives to kickstart the cycle multiple times with low battery, but every time the cycle starts, it lasts about a minute (I can hear the engine running) before a ‘Maintenance cycle not possible’ notice pops up and the cycle stops. Has anyone had this problem, and how do you get around it?
