THE BRAKE PEDAL GOES ALMOST TO THE FLOOR WHEN THE BRAKES ARE APPLIED. I DO NOT HAVE MUCH BRAKING AND I HAVE CHANGED THE BRAKE PADS (FRONT/REAR) AND BLED THE BRAKES AND IT DID NOT HELP. I HAVE READ THAT THE PROBLEM IS WITH THE HYDRAULIC ELECTRONIC CONTROL UNIT (HECU) AND THE PART IS COVERED UNDER RECALL FOR THE 2011 HYUNDAI GENESIS (RECALL 13V489000). SINCE IT IS THE SAME PART THAT IS USED ON THE 2011 GENESIS, DOES THE RECALL COVER THE EQUUS WHICH IS THE SAME CAR.

SIMILAR COMPLAINT AS NHTSA ID NUMBER: 11058378. THE FRONT END DROPPED TO THE GROUND AND THE ESC INDICATOR ILLUMINATED. NOTED THAT THE FRONT AIR-STRUTS WERE TO BE REPLACED. REPLACED THEM IN OCTOBER 2018. HOWEVER IN MARCH 2019, THE TOTAL CAR HAS DROPPED LOWER THAN EARLIER. THIS WHILE SITTING. TRIED TO RESTART CAR TO SEE IF ALL SYSTEMS WOULD RESET, BUT TO NO AVAIL. TOO DANGEROUS TO DRIVE AROUND.

CAR BRAKES FAILED TO SLOW CAR IN EMERGENCY TRAFFIC ON HIGHWAY, BRAKES WERE WORKING FINE THEN THE PEDAL WENT TO THE FLOOD AND ALMOST HIT THE CAR AHEAD. REAR BRAKES WERE NEW, REPLACED FRONT PADS, BUT BRAKE PEDAL STILL GOES TO THE FLOOR. THERE WAS A RECALL FOR GENESIS HCU , WHICH HAS THE SAME PART AS THIS CAR, THE COST OF REPAIR IS $3000. THE CAR HAS 39000 MILES , I BELIEVE THE CAR HAS A DEFECTIVE HCU, SIMILAR TO THE SISTER CAR THE GENISIS WHICH WAS RECALLED. IT IS DANGEROUS TO DRIVE, THE REPAIR COST IS ENORMOUS AND FORCES PEOPLE TO KEEP DRIVING WITH DEFECTIVE BRAKES. DRIVING WITHOUT NEEDING TO STOP SUDDENLY THE CAR WORKS FINE. ONLY WHEN TRAFFIC STOPS SUDDENLY DO YOU NOTICE THE NEED TO PUT THE FOOT TO THE FLOOR , AND IT TAKES 100 EXTRA FEET TO STOP. THIS IS AFTER REPLACING ALL PADS AND HAVING THE SYSTEM CHECKED. AT THE BRAKE SHOP. I DRIVE LESS THAN 500 MILES A MONTH AND HAVE HAD 2 NEAR ACCIDENTS.
