Charging issue
I have a 2020 c43. It only has 8500 miles on it. I have a charging issue. Every few days I get a battery low message telling me to drive the car 30-60 minutes to charge it. I have already had the dealership change the battery once. Only three things I can think of: battery drain when car is not running, another bad battery, or bad alternator. I don’t want to use a battery maintainer because I park on the driveway.
any troubleshooting tips.

only add on is radar detector plugged into outlet at rear of console. it turns off when I shut the engine off and open the door. I just tested the battery with a VOM and it read over 14V. but the car still tells me that the battery is low and the remote start app tells me that the battery is low. .

Since you already changed the battery, there is a chance that there is some software outstanding that might solve your issue.
