Large charge loss followed by ghost increase

[tniner]

I have had my X since 2016. Never had this happen. I parked the car on Wednesday with 40% battery left. Return to it today, with 6% battery left. I do not have sentry mode or anything else on in the car. I park in an underground garage and I’ve done this for years and never had this happen, I limped to a supercharger and charged the car up to 80%. I just went down to check, two hours later, to see if it had lost any charge and it’s now at 86%. I am gaining battery. help!
