Originally it threw a code regarding the catlytic converter,replaced it all was good for a week then it threw codes running lean on left bank. cleared them a couple times, every time the check engine light came on it was always preceded by the service stabilitrac light, anyway my mechanic checked it again said it was a vacuum leak, fixed and all is good now for past 3 weeks

ok if thats the case, and theres no codes now, then there may be a pending code, and that MAY be why the traction control light is on. I dont believe a pending code would show on the dash Service light, but it may be setting off the traction control light.

The only way to know this is to have a tester than can read pending codes. i got one at harbor freight, but i would think twice about buying one there (see this post to find out why Cen-Tech 98614 help : OBD-Codes.com) , even though it does the job well. I would get one from sears next time.

good luck!

Today I had the same problem with the Service Stabilitrak, Traction Control lights ON, along with check engine light. The engine went into a slow mode and would only drive about 25mph.

Tabilitrak issues
 

I had some of the same issues with the message (Stabilitrak OFF) displaying at really odd times (backing into the garage, starting from a stopped position, just starting the engine) and I could not replicate the issue. So, I basically ignored it thinking the "check engine light" would eventually come on and I would take it in for service. Well, one day I started moving from a stopped position at a red light and everything on my dashboard blinked on at the same time......stabilitrak, check engine, and a bunch of other stuff that I couldn't read fast enough because the engine stopped.....in the middle of the street. I was done. It would not restart. So, as I was just sitting there in the middle of the intersection trying to find the AAA number. When AAA showed up, the tow truck drive said he could fix it fast. "just turn the key on and off 17 times and the check engine light will go off and you can start the engine." My question; did that fix the engine problem.....answer "no, it just starts the engine and you can drive it!" ARE YOU FREAKING KIDDING ME? I drove to the dealer the next day and they had an AWFUL time trying to diagnose the problem....because the 17 switches of the key reset the computer. again, ARE YOU KIDDING ME? Well, four hours later the mechanics were able to recreate the issue and found that the computer failed. It was replaced at no charge (seems that there is a 70,000 mile? warranty). THANK GOODNESS. Lesson learned....no AAA diagnosis and fix; just make them tow to the dealer.

I have a 2008 Chevy Equinox and the brakes lock up the dash says stablelink off and service traction control

Driving at 60 and dash lights up..service stabiltrak, abs light, traction control lights and all wheel drives.Drove to dealer and checked codes. Seems the hub was bad and piece cracked off. Most likely a MN pothole earlier in the year. Replaced hub and all is well. Jerking was from right side trying to get traction while left not reading so computer turned off systems dealing with stabilitrak, all wheel etc. Works great again.

I have the same year equinox having the same issue, the traction control light comes on followed by the check engine, seems to be a typical issue with this "stabiltrak" in the Chevys as I've seen the avalanches and Tahoes having the issue on other threads, is the ERG valve the typical fix for check engine light? I've yet to have the car plugged in to check why the light is on.

It depends. I was having the same issue with my 08 Equinox. Replaced EGR valve, cleaned tube, did tranny service, and a tune up and still getting the same codes for the EGR valve. I'm stumped, but not giving up!
