My 2011 cruze has had the infamous service stabilitrak and service traction control warning messages and extra dings everytime i start my car for a while now, along with the abs light being on the dash. When they come on i can feel something under my feet sort of engage i would call it. Never drove any different brakes work fine... but lately if those things dont happen and i start driving my car will start stuttering bucking jerking whichever you wanna call it and has little power... UNLESS........ i reach down and turn my traction control off. After that it drives normal .
