Cracked thermostat housing, so I added Blue Devil head gasket sealer into the radiator and now error lights turned on and engine began.

The car has been running slightly hot, so I changed the stuck open thermostat and the thermostat housing that cracked. It was okay for a few days, then began running slightly hot again. So, doing as a mechanic suggested; I used blue devil head gasket sealer through the radiator. It was okay again for a few days and now it is doing the same thing. I drove to work and left work just fine, but when coming out the store a few minutes later I turned it on and a message for service stabilizer track and traction control off came on dash and instantly began to studded/rock while idling but of course got worse as I drove home.

Hi,

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.

Take care,

Joe
