While this is in the model Y forum, the incident I will describe, occurred in a model X. As we have a model Y also, I think this issue affects all Tesla models. I had an occasion to save a video clip so I honked the horn. Later, I reviewed the DASH CAM clips only to find out that my clip was not recorded because the flash drive was full. I did not know this, but I found out that Sentry clips are not over written – only the clips recorded from the DASH CAM itself. As a result, it appears that my drive was full of Sentry clips leaving no room to save a DASH CAM clip. My question is why can’t Tesla provide some pop-up notice informing the driver that the flash drive is full and needs to be either formatted or cleaned? In the car this sophisticated, I don’t believe we should have to try to remember to format the thumb drive on a regular and recurring basis.
