I have my brake light and abs light coming on everyonce in a while.. onstar check said it was something with the vehicle stability control... I didn't know we had that, what could it be?

 

I had that happen a couple of times... turning off / on the car makes it go away...

If it doesn't (had this too) take it in quick... In my case, (when the light stayed on) the ABS Resivior leaked out and shorted the ABS controller... F'ing my whole brake system...

Good Luck.

it'll go off then back on every few days or starts, wierd, but the abs still works... had a little "scare" last night...

 

This happen to me too. The dealer had my car for 3 days.....couldn't find the cause. The dealer even opened a case with GM on my Cobalt.
