2010 Chevrolet Malibu Electronic Stability Control Esc Traction Control System Problems

THE SERVICE ESC AND TRACTION LIGHT CAME ON. I TOOK THE CAR TO THE DEALERSHIP TO BE SERVICED. THE TOLD ME IT WOULD COST ABOUT $700 TO FIX THE ISSUE. TWO DAYS LATER THE LIGHT WAS BACK ON. I CALLED THE DEALERSHIP AGAIN AND HE SAID "OH THAT IS BAD." I TOOK IT BACK IN AND HE APOLOGIZED FOR NOT CHECKING ANOTHER OPTION REGARDING THIS SERVICE. HE TOLD ME IT WOULD COST ANOTHER $500 TO REPLACE THE ELECTRONIC STABILITY CONTROL MODULE. THIS ALL HAPPENED ABOUT 2 MONTHS AFTER THE WARRANTY RAN OUT. I HAVE BEEN RESEARCHING AND THIS SEEMS TO BE A COMMON ISSUE WITH THE 2010 MALIBUS. THE DEALERSHIP ALSO TOLD ME THAT THIS WAS A SAFETY ISSUE AND THAT THE BRAKES COULD LOCK UP WHILE DRIVING DOWN THE HIGHWAY. *TR
