What owners say about the service brakes
Verbatim from NHTSA complaints, newest first
“Passenger side, rear brake line rusted to the point where brakes failed one morning. Brake fluid leaking from rusted brake line. Lost braking pressure while driving. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, independent shop Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No”
“My son was driving this car home from college mid-day on October 8. He had not driven the car for 10 days or so while at school and he did notice the brakes making an unusual sound that day he had never heard. While on the highway, there was a sudden stop ahead of him. When he pressed the brakes they completely stopped working and he rear-ended the car in from of him. The brakes were completely non-functional after the crash and he had to try to stop his car as best as he could without brakes. Luckily there were no injuries, however complete brake failure out of the blue is obviously enormously dangerous. The tow truck driver confirmed that brakes did not work at all and speculated that a "brake-line snapped". I have no idea if that is true or why he thought that. The car is totaled and no inspection of the car has taken place. We have the car at our house and it is available for inspection as we try to figure out what to do with it. There were no warning lights prior to the issue. Less than a week after the accident we received a Notification of Extended Warranty from the car manufacturer regarding a possible issue related to brakes. And we have read about…”
“MY HYUNDAI DEALER CALLED ME TODAY MAY 15, 2019 AND SAID THAT THE ESTIMATE TO REPAIR MY GENESIS BRAKES WOULD COST $2770.00 AT A MINIMUM, MAYBE MORE IF THE WHOLE SYSTEM HAD TO BE REPLACED. IN OTHER WORDS; (PLEASE WRITE A BLANK CHECK TO US.) THIS IS A HYUNDAI PROBLEM AS A MANUFACTURER. THEY PUT DOT 3 FLUID IN THE SYSTEM AT BIRTH OF THE CAR AND IT CAUSED CORROSION INTERACTING WITH THE ZINC PLATING INTERNALLY. PROPER TESTING WASN'T DONE PRIOR TO ASSEMBLY SIGNOFF. THE RECALL CHANGED THE FLUID TO DOT 4 AND IN MY CASE THE FLUID WAS NOT PROPERTY DRAINED AND CHANGED AND MY PICTURES OF THE FLUID PROVE THE SEPARATION AND CRUD IN THE BRAKE SYSTEM. MANY GENESIS HAVE HAD THIS PROBLEM AND HYUNDAI SHOULD BE FORCED TO MAKE THIS REPAIR ON THE AFFECTED CARS. WHAT IS A BIGGER SAFETY CONCERN THEN HAVING YOUR BRAKES GO OUT WHEN APPLIED. MY CAR WON'T STOP AS THE BRAKE PEDAL GOES TO THE FLOOR ALL THE WAY DOWN.THE ABS & ESC LIGHTS COME ON WHEN THIS HAPPENED. THE BRAKE FLUID WAS CHANGED IN 2014 AND AGAIN IN 2019. A NEW MASTER CYLINDER, FRONT BRAKE LINES, BRAKE LIGHT SWITCH AND DIODE WAS INSTALLED IN MARCH 2019. TOOK IT TO DEALER IN APRIL 2019 AND THEY ALL WAS OK EXCEPT ESC LIGHT WAS ON.…”
“MY BRAKE LIGHTS WILL NOT COME ON WHEN I PRESS THE BRAKE PEDAL. I HAVE HAD THE FUSES CHECKED AND THEY ARE ALL WORKING. I CONTACTED MY LOCAL HYUNDAI DEALERSHIP AFTER RESEARCHING THE RECALL ON THE BRAKE LIGHT SWITCH. THEY WILL NOT PERFORM THE RECALL BECAUSE THEY SAID IT WAS ALREADY DONE TWICE. BUT THERE IS OBVIOUSLY A PROBLE IF ITS HAPPENING AGAIN.”
“TL* THE CONTACT OWNS A 2009 HYUNDAI GENESIS. THE CONTACT WAS INFORMED BY EYEWITNESSES THAT THE BRAKE LAMPS ON THE VEHICLE FAILED TO ILLUMINATE. THE VEHICLE WAS SERVICED PER NHTSA CAMPAIGN NUMBERS: 14V713000 (EXTERIOR LIGHTING) AND 13V113000 (SERVICE BRAKES), BUT THE REMEDY FAILED TO REPAIR THE VEHICLE. THE MANUFACTURER WAS NOT NOTIFIED. THE DEALER ADVISED THE CONTACT TO BRING THE VEHICLE IN FOR DIAGNOSTIC TESTING, BUT THE LOCATION WAS OVER AN HOUR AND A HALF AWAY. THE FAILURE MILEAGE WAS APPROXIMATELY 165,000.”
“BRAKES LIGHTS HAVE GONE OUT. HYUNDAI IS AWARE OF THE PROBLEM BUT I AM NOT AWARE OF ANY RECALL. HYUNDAI ISSUED TSB 09-BE-023 TECHNICAL SERVICE BULLETIN 09-BE-023, STOP LAMP Z01 DIODE INSPECTION PROCEDURE, APPEARS TO DESCRIBE THE LOCATION AND PROCEDURE FOR TROUBLESHOOTING OF THE DIODE BUT DESCRIBES THE ISSUE AS " . . . VEHICLES MAY EXPERIENCE THE STOP LAMPS BLINKING ON AND OFF EVEN WHEN BRAKES ARE NOT APPLIED."”
