My right DRL appears to randomly flicker on cold start (car has been sitting for several hours of sleep at home) when my battery is below 40% I have noticed. It seems to go away whenever I press the on/go pedal. I will monitor it, but I guess if it gets worse a service request will be generated for Tesla. Luckily I live near a SC. I find it strange that so far it seems to be tied to SoC and whether or not I press the go pedal.
