I know I have seen a thread about this in the past, I just can't find it. This has happened on my wife's 2022 ST once, but, it has happened to my 2020 ST multiple times, maybe 3-4x since owning it (June 2023). And I think I know why it happens so frequently with me because it might be the way I am doing it.
Randomly the brakes will fail to work coming out of Park and releasing the parking brake, almost as if they are only being partially applied and the vehicle will continue to move forward until you disengage the brakes and depress the brake pedal again. You can tell the issue is happening because the brake pedal has a stiffer feeling to it. The last few times it has happened, I think it's because I did everything a bit too fast and the vehicle didn't like it (I was in a rush), I depressed the brake pedal, put it into Drive, and immediately released the handbrake, the brake pedal then a weird stiff feeling, the vehicle rolls forward and if you try to apply more pressure on the brake pedal, it does not make a difference, until you get off the brake pedal and depress it again, then the brakes work properly.
I'm going to see if I can find a way to replicate it before I go for an oil change in a few weeks. either way, I will mention it to the dealer to see if they can check it. Considering it happened once on my wife's ST, I'm guessing it's another one of those weird ST glitches, only this one can have severe consequences if it happens at the wrong place and time.
