NHTSA Complaint #11183169 — 2014 HYUNDAI SONATA

ESC LIGHT AND HARD BRAKING ISSUE(ABS MODULE?): ESC LIGHT TURNS ON AND THE CAR APPLIES HARD BRAKES WITHOUT ANY ACTION FROM THE DRIVER WHILE DRIVING. THIS HAPPENS WHILE DRIVING ON A STRAIGHT ROAD OR FREEWAY (NOT WHILE TURNING). SOMETIMES, THE ESC LIGHT DOESN'T TURN ON BUT THE BRAKES STILL GET APPLIED WHILE IN MOTION WITHOUT ANY ACTION FROM DRIVER. IT HAS HAPPENED 5 TIMES SO FAR - 2 OF THOSE WHILE DRIVING AT MORE THAN 60MPH ON FREEWAY BUT WAS FORTUNATE TO PULL TO THE SHOULDER SAFELY. ONE INSTANCE OF THE PROBLEM SHOWED UP WHEN THE CAR WAS STATIONARY BUT WITH ENGINE RUNNING (AT A PARKING LOT). AS YOU COULD SEE, THIS IS A SAFETY ISSUE PUTTING US IN DANGER WITHOUT ANY PRIOR INDICATION OR NO KNOWN RESOLUTION. I HAVE TAKEN IT TO THE LOCAL HYUNDAI DEALER SERVICE CENTER BUT THEY CANNOT FIND THE ROOT CAUSE YET. THEY HAVE ALREADY TRIED REPLACING BRAKE SWITCH BUT THAT DIDN'T HELP. I HAVE FILED A CASE WITH HYUNDAI DIRECTLY TOO AND WAITING TO HEAR FROM THEM.
