Default Low voltage - rear taillight message

Car is at the dealer due to intermittent “check rear tailight” messages.
dealer says it is coming from low voltage and that i should use a battery tender. I drive the car daily for 10 min commute each way at a minimum. It is my daily driver. I don’t understand why i should need a battery tender when all of my previous non porsches went through the same daily commute with no issues. Car has always started with no problems. Is there something the dealer is missing?
Thanks in advance!

hmmmm, this sounds more like maybe a loose connection or defective rear tail light. They are LED's so they shouldn't "burn out"

try removing the taillights to check the connections and wiring. If you have low voltage it would effect A LOT more than your tail lights.

I think 10 minutes of alternator charge time is not enough, especially in the winter, hence the battery tender recommendation.
