Max G2 sudden random park mode

I am having this issue where sometimes even after i have held the brake to disengage park mode and push the scooter as usual to start the throttle. The throttle just doesn't work even if i push all the way, i have to stop completely and press the brake a 2nd time to release it. I have the start speed set at 2 Km/hr but even after pushing at 5-7 km/hr it still wont release till i push the brake a 2nd times while i stop completely. This also mostly just happens when im going down an incline for example going from a pedestrian path to a road while im crossing the road.
