I know this may not be the answer you were hoping for, but unfortunately, there is no 1-answer, "it's this..." kind of answer here. There are dozens of parts and sensors that are used in both the ABS and Stabilitrak systems. At this point, the best bet is to have the Diagnostic Trouble Codes scanned from the on-board computer. These trouble codes will point towards the part/sensor that has the problem and from there, the correct diagnosis and repair can then be made. SOME local parts stores, like AutoZone, will have the correct scan-tool to read the codes and will do so for Free (except in California) right in their parking lot. If you cannot find a local part store with the correct scan-tool, then a shop will be needed. With that said... a common fail item on these vehicles that can set both the ABS and Stabilitrak lights is a faulty Wheel Speed Sensor (aka "ABS Sensor). These sensors report info to both systems. Unfortunately, there is one of these sensors at each wheel. To which is faulty, we'd need those diagnostic codes. You can do a preliminary check by inspecting the electrical connectors and wire harnesses to these sensors, looking for any loose, broken or damaged wires. Inspect under the sensor for any debris that may be blocking the sensor from reading the tone ring below. If nothing visual stands out, then unfortunately, we'd need those codes before we can proceed. Sorry I could not be more accurate in my answer, but like I say, there's just too many items at play here to take a guess and be correct.
