The brake lines and fuel lines were corroded. The corrosion of the brake lines would lead to brake failure and the corrosion of the fuel lines would lead to a fire. The Hyundai dealer was the first to find the brake problem and after inspection by my mechanic, the fuel lines were also found to be corroded. I took my car in for a recall service at the dealer and after the service my brake light would illuminate when decelerating(with or without brakes being applied) .

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.

I was driving home on January 1, 2023 at 5 AM at about 60 mph on an interstate when I heard a sound come from the back of my car and then looked into the rearview mirror and smelled smoke and saw fire flames in my rear and side mirrors. I tried to use my brakes to stop my car, but the brakes would not work, so I took it out of Drive and put it into park… which slowed the car down and I was able to exit the car right before it burst into flames. The car is now a total loss.

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.

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.

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.

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.
