Common Causes for the "Service Stabilitrack"

[abdullah_Zahra]

Intermittent Stabilitrack message comes up after 20-30 mins of driving. Shutting the car off and starting it again will vanish the light until another 20-30mins for the same scenario to happen again.
The DIC also shows an Intermittent "Service Breaks soon" message so I thought these two messages can be related?
I had a p0573 code regarding the brake switch sensor that I replaced myself (noticed that cruise control won't work) However, after the new sensor install cruise control also didn't work!

Had the vehicle scanned, no codes within the engine, but the EBCM gave me back 3 codes:
C0299:5A "brake boost regulation pressure sensor plausibility failure"
C0253 "centering error"
C1100:00 "base brake system pressure circuit"

I am positive that the stabilitrack issue is somewhat related to the brake system now but honestly I have no idea where to start at the moment. Could this be a failing brake booster maybe? I know that my brake fluid is due for a change now but I don't think it can throw all these codes, am i right?
Maybe the booster's vacuum sensor is the issue? not the whole booster assembly?
Any help on where to start is greatly appreciated! How can I tell for sure that the booster is the issue here? I know braking power should be low if the booster is the issue here, but the brake pedal is not stiff at all and the car seems to be braking quite well.

Year and model will help please.

Steering wheel position sensor is out, that's likely the cause of stabiltrac fault

Aftermarket brake switches are a cause as well as the abs sensors in the front hubs.

The ABS sensors are generally not serviceable and the hub / bearing assembly is replaced. The abs sensor is pressed into that.

My favorite that never threw a code was the cps located behind the starter. It caused a long crank for over a year until it finally threw a DTC for it, lit up stabilatrac and killed the tacho. It went away on next start up.
