Model X clicking, humming...

    Hi All,

    I have had my MX Performance for about 2 weeks. I was doing a lot of work in the garage this weekend and it seemed like the X would make clicking noises ever 15-20 minutes followed by a high pitch hum for several minutes before it went quiet. It repeated this cycle dozens of times.

    Just curious what the car is doing during this time?

    Some background:

    Garage temp = 68 degrees
    Sentry mode has been told not to enable at home
    Summon mode is off
    The Tesla wall charger was not plugged in

    Using the Stats iOS app, here’s the phantom drain over the last week (while the car is idle):

    Sunday: Lost 6.8 miles in 19.5 hours
    Saturday: 10.1 in 38.8
    Friday: Incl in Saturday numbers (not sure why)
    Thursday: 4.2 in 5.2
    Wednesday: 6.5 in 17.3
    Tuesday: 20.8 in 20
    Monday: (Incl in Tuesday numbers)
    Sunday: (Incl in Tuesday numbers)

    Could my car be waking up every 15-20 mins because it is detecting movement around it as I work in the garage?

    Another question, if I plug the car in and charge it to a percentage like 80%, it will reach 80% and then stop. Then the miles available start to slowly decline. At what point will the charger start charging the car again, if ever? Thinking of a scenario where I go out of town for a month or two.

    I’m learning! Thanks for any tips!!!

    The clicks are usually when the main battery is connected to charge the 12v battery or to power up the HVAC. If you are running Sentry Mode or Cabin Overheat Protection, or anything else that prevents the car from sleeping...even accessing from the app will do that.

    You can keep sentry mode off if you are comfortable that the car is safe in your garage. Yes, having it on will definitely keep the car on and alert.

    If your car loses more than 2 or 3 percent t it will be topped up back to your set charge limit. This typically happens every 2 to 3 days.

    If your key is within range it will wake the car or prevent it from sleeping. I hang my key on a wall in the garage out of range.

    if you are losing more than 1 mile a day phantom it’s not sleeping as well as it could.

    I don’t run apps.
