If there wasn't an issue with a head gasket, I don't know why that recommendation was made. However, the traction control light/stability track isn't related.
If I had to guess, I suspect there is a faulty wheel speed sensor or even low brake fluid, which is easy to check.
We have a couple of ways to approach this. The most accurate would be to have the can-bus scanned. CAN stands for controller area network. Basically, all the different computers and modules are tied together via a few wires. This type of scan will retrieve codes regardless of the module storing them. Here is a link that better explains it and how it's done:
If you are unable to have that done, you can check each of the wheel speed sensors using a multimeter. All you do is disconnect the connector one at a time at each wheel, connect a multimeter to the wheel side of the sensor, then safely lift that tire off the ground and spin it. If the sensor is good, it will produce a voltage signal that is readable. Here is a link that explains how this is done:
If you chose to do it this way, I attached pics below showing the locations of the sensors. All will be behind the wheels of the vehicle. See pics below.
Let me know what I can do to help or if you have other questions.
