My model S is at the body shop to repair a damaged bumper/qtr panel. I had to drive almost 100 miles to get to this particular body shop and I've kept track of the cars location and SOC thru the phone app over the last week. The car has been sitting, unplugged, for almost a week now (waiting on an insurance adjuster) and the SOC is now down to just over 20 miles after vampire loads have eaten away from 55 miles SOC 5 days ago. I expect the body shop will continue working on it in the next couple of days and finish up within another week or so. Do I need to be worried about the charge dropping under 20 miles? Do I need to tell the shop to plug it up immediately? They said they would charge it up before I picked it up, but I don't know if there is any negative impact to having the SOC drop down into the teens or lower.
