Hi guys,

Recently I have found out my car shows sign of strange, the car is not on, but it made something tricking or grinding or winding sound from front of the car.
I feel like something inside and moving around.
It's quite regularly happened.

Does anyone has similar symptoms like me?

    Sounds like the fluid pumps running to cool or heat the batteries, even with the car off. Usually, it can occur when charging.

    This could also be the air suspension adjusting, if it lasts 10 or less seconds and occurs after a drive.

    That is the BMS (battery management system) doing its thing.

    Nothing to see here, move along..... :-)

    Ticking and grinding and something moving in the car don't sound like cooling pumps or AC to me.
