2011 Hyundai Genesis Brakes Problems

The HECU has been malfunctioning in my car for over a year now. It is an open recall for my make, model and year of car. I took it to Bob Rohrman Indy Hyundai and they diagnosed the failed part. This part affects my ABS. There are currently two warning lights on one for the ECS which is the traction control stabilizer and the ABS light is on. Meaning the use of the breaking system is limited and not working properly. I have asked the corporate Hyundai to uphold the recall warranty but I was advised they would not cover this because my vehicle has a rebuilt title. I drive my vehicle on a daily basis and I’m terrified of my brakes going out. The corrosion from the fluid is what causes the HECU to malfunction and it is so scary to think about. This problem was diagnosed and first reported to my his dealership on 6/23/2022.

IBRAKE FAILURE! HYDRAULIC MODULE ASSY FAILURE WAS DRIVING THE VEHICLE AND DURING THE DRIVE, MY BRAKE ALL OF A SUDDEN BECAME SOFT AND REQUIRED ME TO PUSH ALL THE WAY TO THE FLOOR TO STOP THE CAR. I BELIEVE IT'S REFERRED TO AS SPONGY BRAKES. I TOOK THE CAR TO AN INDEPENDENT MECHANIC SHOP AND THEY DIAGNOSED A FAULTY HYDRAULIC MODULE ASSEMBLY. I ALSO CALLED THE DEALER AND THEY MENTIONED THERE WAS A RECALL ON THE BRAKE FLUID DUE TO ITS POTENTIAL TO CAUSE CORROSION IN THE BRAKE SYSTEM. THE DEALER IS NOW QUOTING ME ~$3,400 TO REPAIR AND REPLACE THE HYDRAULIC MODULE ASSY. WOW!! I CALLED HYUNDAI USA AND THEY SAID SINCE THE CAR WAS OUT OF WARRANTY THEY WOULD NOT COVER THE REPAIR, I INFORMED THEM OF THE RECALL ON FLUID AND THEY SAID IT DOES NOT COVER THE PARTS THAT WERE DAMAGED BY THE BAD FLUID. THIS IS UNFAIR AND EXCESSIVE BEHAVIOR ON THE PART HYUNDAI. CLEARLY THEY RECOGNIZED THE FLUID WAS DAMAGING BRAKE COMPONENTS BUT ARE UNWILLING TO COVER RELATED REPAIRS. THE BRAKES ON THIS CAR ARE AN ACCIDENT WAITING TO HAPPENING SINCE THE BRAKES ARE FAILING. I WOULD NOT BUY ANOTHER HYUNDAI VEHICLE KNOWING THEY WON'T COVER CRITICAL SAFETY COMPONENTS. OTHERS HAVE VOICED THE SAME ISSUE WITH NO SUPPORT FROM HYUNDAI. *TR

THE Z01 DIODE FAILED CAUSING THE BRAKE LIGHTS NOT TO ILLUMINATE WHEN THE BRAKE PEDAL IS PRESSED. THERE IS NO WARNING TO THE DRIVER THAT THIS FAILURE HAS OCCURRED. THIS IS A KNOWN ISSUE BY HYUNDAI. THEY RELEASED A TSB, TECHNICAL SERVICE BULLETIN 09-BE-023, CONCERNING THE ISSUE BUT THE SOLUTION IS TO REPLACE THE SAME DIODE WHEN IT HAS FAILED. NO IMPROVEMENTS HAVE BEEN MADE TO MAKE THE PART MORE RELIABLE. IT IS A SERIOUS SAFETY ISSUE AS THE DRIVER HAS NO INDICATION THAT THE BRAKE LIGHTS DO NOT WORK PUTTING THEM, PASSENGERS, AND OTHER DRIVERS AT RISK OF A SERIOUS REAR END COLLISION.

MY 2011 HYUNDAI GENESIS IS EXPERIENCING BRAKING FAILURE. I HAVE ALMOST HAD ACCIDENTS DUE TO MY CAR'S INABILITY TO COME TO A STOP IN A REASONABLE TIME, ESPECIALLY WHEN FOLLOWING VEHICLES THAT COME TO A SUDDEN STOP. THE PEDAL DEPRESSES ALMOST TO THE FLOOR AND IS VERY SPONGY. THE PROBLEM IS INTERMITTENT BUT CONSISTENT. I RESEARCHED THE ISSUE AND FOUND THAT THERE WAS A RECALL RELATED TO THIS ISSUE, BUT FOR SOME REASON, HYUNDAI EXCLUDED MY VIN DESPITE IT FALLING WITHIN THE MANUFACTURE PERIOD OF HYUNDAI CARS EXPERIENCING THE ISSUE. I TOOK THE CAR TO THE HYUNDAI DEALERSHIP AND THEY DIAGNOSED A FAILED ABS SYSTEM, SPECIFICALLY STATING THAT THE INTERNAL SEALS OF THE HECU (ESC UNIT) WERE WORN CAUSING POOR SEALING. THIS MAY BE RELATED TO THE CORROSIVE BRAKE FLUID THAT THEY REPLACED FOR THEIR CAMPAIGN TL6. UNDER HYUNDAI'S RECALL CAMPAIGN 114, THE HECU SYSTEM SHOULD HAVE BEEN INSPECTED AND REPAIRED OR REPLACED IN ADDITION TO CHANGING THE FLUID. HYUNDAI MERELY REPLACED THE FLUID. THIS HAS CAUSED A DANGEROUS SITUATION WITH MY BRAKING SYSTEM THAT COULD HAVE BEEN AVOIDED.

I PURCHASED MY USED PRE-CERTIFIED HYUNDAI GENESIS 20 11 CAR IN FEBRUARY 2014 AND SHORTLY THEREAFTER I FOUND THAT MY BRAKES WHICH ORIGINALLY WERE FIRM WOULD GO DOWN TO THE FLOOR OR NEARLY TO THE FLOOR WITHIN 6 MONTHS I DID SOME RESEARCH ON THE CAR AND FOUND THAT IN 2013 HYUNDAI CORPORATION ISSUED A RECALL ON THE ABS SYSTEM DO 2 CORROSIVE BRAKE FLUID THAT WAS COULD POTENTIALLY CORRODE THE ABS SYSTEM AND 2013 THE BRAKE FLUID WAS REPLACED ON MY CAR PRIOR TO MY PURCHASE. HOWEVER HYUNDAI DID NOT INSPECT WHETHER ABS SYSTEMS HAD ALREADY BEEN DAMAGED BY THIS CORROSIVE BRAKE FLUID AND MERELY REPLACED IT MY CAR HAS AN ABS SYSTEM THAT HAS BEEN TESTED AND IT FAILS. THE BRAKE PEDAL ON MY CAR NEARLY TOUCHES THE FLOOR AND IT IS DIFFICULT TO STOP THE CAR SAFELY. I WAS DRIVING IN THE RAIN RECENTLY AND JUST MISSED HITTING A CAR THAT STOPPED SUDDENLY.

BRAKES ARE VERY MUSHY. OFTEN GOING TO FLOOR WITHOUT STOPPING. HAVE TO PUMP BRAKES TO STOP. DEALER SAYS THE HEC UNIT NEEDS TO BE REPLACED (PART IS $3500). THIS 2011 HYUNDAI GENESIS WAS BUILT IN DURING TIME FRAME OF EARLIER RECALL BECAUSE HYUNDAI WAS USING CORROSIVE BRAKE FLUID. EARLIER MODELS WERE RECALLED BUT MINE WAS NOT? WHY? NOW THAT 6 YEARS HAVE PASSED, THE CORROSIVE BRAKE FLUID IS NOW CAUSING LATER MODELS TO FAIL. ALL MODELS BUILT DURING THE TIME FRAME IN WHICH CORROSIVE BRAKE FLUID WAS USED SHOULD BE RECALLED AND MFG SHOULD BE RESPONSIBLE FOR REPLACEMENT OF THE HEC UNIT ... NOT JUST THE BRAKE FLUID. ALL QUESTIONABLE VEHICLES SHOULD HAVE BEEN RECALLED IN THE FIRST RECALL.

AFTER A BRAKE JOB, I TOOK THE CAR BACK TO SAY THAT THE PEDAL WAS GOING TO THE FLOOR. I WAS TOLD I HAD A LEAK IN THE MASTER CYLINDER. GOT THAT REPAIRED. AFTER HAVING THE MASTER CYLINDER REPAIRED, I AM NOW BEING TOLD I HAVE TO REPLACE THE HYDRAULIC ELECTRONIC CONTROL UNIT (ABS, HECU). DID SOME RESEARCH, AND SAW THAT THIS WAS A RECALL ISSUE FOR 48,000 GENESIS BETWEEN THE YEARS OF 2008 AND 2012. ISSUE SEEMS TO BE CAUSED BY BRAKE FLUID CORROSION. MY CAR WAS NOT PART OF THE RECALL. I REPORTED THE INITIAL ISSUE AT 64,000 MILES. CAR IS NOW AT 80,000. IT HAS BEEN SITTING AT THE DEALERSHIP BECAUSE IT HAD AN ENGINE REPLACED COVERED UNDER WARRANTY.

WHILE THE AUTOMOBILE IS IN MOTION THE BRAKE PEDAL IS MUSHY TO THE POINT THAT IT ALMOST REACHES DEAD BOTTOM BEFORE ENGAGING THE BRAKES. THIS HAPPENS BOTH ON THE HIGHWAY AND ON THE STREET NO MATTER THE SPEED. REPAIR SHOP STATES THAT ITS THE ABS HYDRAULIC MODULE IS DEFECTIVE. HYUNDAI DEALER STATES THAT IT IS FOR THE FLUID RECALL. IT IS NOT FIXING THE BRAKES.

I WAS SITTING IN MY CAR WITH THE EMERGENCY BREAK ENGAGED WHEN MY CAR STARTED TO ROLL BACK DOWN MY DRIVEWAY. NO MATTER HOW HARD I TRIED I COULD NOT PUSH THE BREAK IN AND THE EMERGENCY BREAK WAS ON THE ENTIRE TIME. MY DOOR IS NOW CRUNCHED UP FROM ROLLING BACK INTO A TREE. IT WENT ALL THE WAY DOWN MY DRIVEWAY, ACROSS THE STREET AND INTO MY NEIGHBORS YARD BEFORE MY HUSBAND WAS ABLE TO GET IT TO STOP BY PUSHING THE BREAK PEDAL AS HARD AS HE COULD. I BRUISED MY SHOULDER TRYING TO GET OUT OF THE CAR WHILE IT WAS ROLLING AWAY.

MY CAR HIT AND DROVE ONTO THE CURB WHERE IT REMAINED UNABLE TO MOVE UNTIL AAA ARRIVED. I BROKE BOTH LEFT WHEELS AND THE AXEL ALONG WITH OTHER SERIOUS DAMAGE TO THE FRONT OF MY VEHICLE.

THE BRAKE PEDAL WOULD BECOME SOFT WHILE DRIVING AND WOULD TRAVEL TO THE FLOOR WITH LITTLE TO NO STOPPING POWER. SEVERAL TIMES BOTH ON CITY STREETS AND FREEWAYS THE VEHICLE BECAME DIFFICULT TO SLOW OR STOP AND ALMOST RESULTED IN SEVERAL COLLISIONS. THE VEHICLE HAD BEEN RECALLED AND PREVIOUSLY SERVICED WITH NEW BRAKE FLUID PER NHTSA CAMPAIGN 13V489000. AT 59,000 MILES I HAD ALERTED THE HYUNDAI SERVICE DEPARTMENT ABOUT THE BRAKE FAILURE. THEY WERE UNABLE TO REPRODUCE THE PROBLEM. THE PROBLEM PERSISTED AND NOW THEY WERE ABLE TO REPRODUCE THE ISSUE. THE INTERMITTENT FAILURE OF THE BRAKE SYSTEM IS LIFE THREATENING AND NEEDS TO BE ADDRESSED. THEIR IS QUITE OBVIOUSLY DEGRADATION OF THE BRAKE SYSTEM COMPONENTS DUE TO THE ORIGINAL BRAKE FLUID NOT HAVING CORROSION INHIBITORS.

I WAS DRIVING AT 35 MPH IN THE LANE, THE CAR ON THE LEFT LANE HIT THE REAR BODY AND TIRE OF DRIVER SIDE, BUT THE CAR DIDN'T STOP EVEN AFTER THE IMPACT. AFTER THE COLLISION, I PRESSED VERY HARD ON THE BRAKE PEDAL TO STOP, BUT IT KEPT MOVING, EVEN INCREASED ITS SPEED UP TO 60 MPH, AND TURNED INTO THE DIFFERENT DIRECTION. ALSO THE WHEEL WAS STUCK BY ITSELF AND I WAS NOT ABLE TO TURN ANYWHERE WITH MY HANDS. IT WENT OFF THE OPPOSITE SIDE OF THE ROAD WITHOUT ANY CONTROL. 20 YEARS OLD TOYOTA CAMRY WAS ABLE TO STOP AT THE SPOT OF COLLISION, BUT HYUNDAI GENESIS COULDN'T. THE WHEEL AND THE BRAKE WERE BOTH STUCK AND UNABLE TO BE CONTROLLED AND CRASHED INTO THE ELECTRIC POLE. THE AIR BAG WAS DEPLOYED, AND HYUNDAI GENESIS WAS TOTALED. IN 2014, THE BRAKE RECALL SERVICE WAS RECEIVED TWO TIMES FROM THE DEALER. THERE MUST BE THE MECHANICAL FAILURE IN THE BRAKE, SPEED CONTROL, AND THE WHEEL WHICH CAUSED THIS TOTAL LOSS. I WAS INJURED AND TAKEN BY THE AMBULANCE LATER. I NEVER HAD ANY ACCIDENTS LIKE THIS BEFORE WITH ANY OTHER CARS! *TR
