This had happened before when the car was relatively new and I knew the brake pedal being pressed is not being sensed by the ECU.
BHPian tharian recently shared this with other enthusiasts.
An issue I faced when my sister’s 2020 ZS EV was given to the valet at a hotel.
The car was parked on an up ramp and the valet was asked to get the car. My car was parked next to it and when I went to take my car, I saw couple of guys trying to get the car to move. But every time they tried, the car was rolling back. Thankfully, there was no car parked behind. I realized they are going to screw up something and of course they will not take responsibility either if something does go wrong. I asked them to get out of the car and what I noticed was, the motor was not on and the orange battery symbol with a line across was lit on the dash. These guys were fiddling with the drive knob without the motor being on. At this point because of the constant braking without the motor running, the brake pedal had become hard, but worked and pressing the start button was not starting the motor but only going to accessory mode. The parking brake was not working either which was causing the car to roll back every time I let go of the brake.
It seemed like these guys were pressing the start button multiple times and not knowing the motor would have been turning on and off and at the same time pressing the brakes that the brake pedal became hard, that it stopped registering that it was pressed for the motor to power on.
This had happened before when the car was relatively new and I knew the brake pedal being pressed is not being sensed by the ECU. I applied more pressure on the brake and hit the start button and finally got the drive knob to work, but the motor was still not powering on. Hit the power button once more and finally it turned on.
In between this, the same error which came up the last time this happened saying HW Battery shut down came up which cleared once the motor powered on.
Lesson learnt, not to give the car to valet at random hotels.
