Abs, vsc trac, vsc off

My car will turn these off. It may be when I'm turning quickly, or maybe it's random. It's hard to tell, I just see sometimes it turns off. If I put the car into park, , take the key out and turn it back on, it's fine again. I also hit the brake and it turned back on in one particular instance.

My car also will have a hard time shifting from park and the brake has a lot of give in it. I took it to two places, they claim "there's nothing wrong" but it didn't use to be like this. There's definately something off.

I don't know much about cars, but any tips would be appreciated.

I could be wrong, maybe check out the yaw rate and deceleration sensors for the traction control system.
If it happens under hard cornering or braking you could be getting a faulty signal from one or both sensor that turns it off, default mode basically.
Seems like a logical place to start to me.
I don't think that would set an engine code, maybe someone more knowledgeable than I am could confirm or deny that. And maybe confirm or deny if my thoughts make any sense to anyone else.
A dealer should be able to check the function of the sensors, again, I would think.

My break is pretty spongy, if I tap the breaks rapidly and lightly, the lights turn back off
