ND RF battery goes flat after 2-3 weeks

 

Not sure if it applies to yours with it being a 2018, but there was a known issue with RFs cruise control draining the battery.  For reference, it is not unusual for me to leave my soft top in the garage for 4 weeks or longer without a single start and i’ve never had a problem (i do have a voltmeter and charger which i use if storing the car over winter)
