Assuming you applied the EBP on a flat surface, it was the low (13.5 kN) clamp load that it put on, which might not have been enough to hold the car stationary. According to you, there was a constant pulling load because you kept the transmission in D and, at the time, the brake pads/discs could have been slippery (exposed to contaminations from snowy roads). Your car moved forward not because the EBP released, but because the parking brake pads slipped. When you put the transmission back to P, there was no pulling load and that's why it held successfully. It might work some other times, but not this time. So, I'd say there is nothing wrong with your car.

However, you can manually force the EBP to apply full clamp load (of 16.5 kN) regardless of the surface gradient the car is on by pulling and holding the EBP switch for more than 3 seconds.
