There is a service bulletin to reprogram the EBCM, electronic brake control module, for your concern. If they already did that then you may have a battery issue, shifted plates?, which can cause all kinds of crazy stuff.

Good Luck,

#PIC5432C: Service Stabilitrak Message Displayed At Startup - (Feb 20, 2013)
Subject: Service Stabilitrak Message Displayed At Startup Models: 2010 - 2014 Chevrolet Camaro

This PI was superseded to update model years and add warranty info section. Please discard PIC5432B.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern A customer may comment of an intermittent Service Stabilitrak message being displayed in the DIC only at startup and that the message is gone within seconds of starting the engine. This message is displayed during the bulb check of the other IPC indicators. This message will not remain on and no codes will be stored in the EBCM.
This concern will only occur under specific sequences of ignition switch operation. Such as a customer that quickly "flicks and releases" the ignition switch during Start/Crank mode. After the ignition switch is released and engine starts the DIC message of "Service Stabilitrak" may be displayed at that time. This concern may not occur each time this ignition switch sequence is performed.
Recommendation/Instructions Note: Do NOT replace any parts in an attempt to resolve this concern.

A revised calibration is now available in TIS2WEB for the EBCM. If no EBCM codes are stored and the "Service Stabilitrak" message is only displayed at startup for a few seconds, then reprogram the EBCM with the revised calibration. Please SPS program the EBCM with the latest software for "New operating system to address Service Stabilitrak message displaying at key up."
Important: This software fix will greatly decrease the possibility of a customer seeing this message on the DIC after startup. After this EBCM update has been performed, it is still possible that the message may be displayed after key-up in rare instances. In these instances, the condition occurs when the battery has a low state of charge. If this concern can ever be duplicated in the shop after the EBCM has been reprogrammed, check the state of the battery and charge it as needed. Make no further repair attempts on the vehicle past that point.
