WHILE DRIVING ON FREEWAY TRACTION CONTROL OFF LIGHT CAME ON THE ENGINE SPEED REDUCED CAME ON AND CAR IMMEDIATELY WENT FROM 60 MPH TO 15-20 CAUSING ME TO SPIN OUT AND LOSE CONTROL ON FREEWAY AND EVENTUALLY SLAMMED INTO SIDE OF ROAD, (MANAGED TO DRIVE HOME GOING ABOUT 15 MPH AT 1:00 IN THE MORNING)BENDING MY AXLE AND THE NEXT DAY ON THE NEWS IT WAS REPORTED CARS WITH ONSTAR WERE HACKED. NEXT MORNING NO LIGHT WAS ON IN THE CAR AND ABLE TO DRIVE WITH BENT AXLE. REPAIRS COMPLETED AND MY INSURANCE RATES WERE INCREASED. ONE YEAR LATER LIGHT CAME ON AGAIN TRACTION CONTROL OFF THEN ENGINE SPEED REDUCED AND CAR WENT FROM 40 TO 15 (LUCKILY I JUST GOT OFF FREEWAY GOING TO WORK) ON SURFACE STREET AND MANAGED TO MAKE IT TO WORK. CALLED CHEVROLET DEALER AND WAS TOLD MANY DIFFERENT THINGS. WAS TOLD THAT PARTICULAR LIGHT COMES ON WHEN ANYTHING GOES WRONG WITH THE CAR TO PREVENT FURTHER DAMAGE TO "THE CAR" BUT PUT LIVES AT RISK. CHECKED THE CHEVROLET FORUM AND THIS HAPPENS QUITE OFTEN AND PEOPLE SAY GET RID OF IT AS SOON AS POSSIBLE AND DON'T USE IT AS A FAMILY CAR BECAUSE IT CAN STALL ON THE HIGHWAY. THIS FEATURE SHOULD BE REMOVED FROM ALL VEHICLES. I WAS TOLD THERE WAS A PRIVATE RECALL ON THE 2011 EQUINOX THROTTLE BODY, SHAME ON CHEVROLET, SHAME ON ONSTAR!
