SERVICE BRAKES
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.

SERVICE BRAKES
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.

SUSPENSION, WHEELS
AFTER SEVERAL FAILED ATTEMPTS TO FIND A SERVICE CENTER OR AUTHORIZED DEALER TO ADJUST MY ALIGNMENT, I FELT IT WAS NECESSARY TO FILE A COMPLAINT REGARDING MY CONCERNS ABOUT MY VEHICLE'S FRONT TIRE ALIGNMENT. MY MOST RECENT EXPERIENCE OCCURRED ON DECEMBER 14, 2016 AFTER GETTING A NEW SET OF TIRES FOR MY CAR. INCLUDED IN THE TIRE FITTING SERVICE WAS A WHEEL ALIGNMENT CHECK AND ADJUSTMENT. HOWEVER, THIS IS NOT THE FIRST TIME I HAVE ENCOUNTERED ISSUES WITH A SERVICE CENTER SAYING THEY ARE UNABLE TO ADJUST MY FRONT CAMBER AND CASTOR ADJUSTMENTS BECAUSE THE "MANUFACTURER DOES NOT SPECIFY" WHAT THESE ALIGNMENTS SHOULD BE. PERHAPS THE STRANGEST PART ABOUT THIS IS THE FACT THAT THERE ARE SPECIFICATIONS FOR THE REAR WHEELS. I HAVE EVEN CONTACTED SEVERAL HYUNDAI AUTHORIZED DEALERSHIPS HERE IN INDIANAPOLIS AND THEY TOO INDICATE THEY ARE UNABLE TO MAKE THE PROPER ADJUSTMENTS. MY LAST RESORT WAS TO CONTACT HYUNDAI USA TECHNICAL SERVICE TO SEE IF THEY COULD OFFER ADVICE AND THEY'RE ONLY FEEDBACK WAS THAT I NEEDED TO VISIT A LOCAL AUTHORIZED DEALER FOR SUPPORT ..... FORTUNATELY, I HAVE NOT BEEN IN A LIFE-THREATENING SAFETY SITUATION DUE TO THIS DEFECT BUT WITHOUT THE ABILITY TO PROPERLY ADJUST THE ALIGNMENT MY TIRES WILL NEVER WEAR PROPORTIONATELY. THIS IS INCREDIBLY CONCERNING BECAUSE THE TREAD LIFE ON ANY TIRES I HAVE INSTALLED ON MY CAR CONTINUES I LESSEN. I FELT INCLINED TO REPORT THIS ISSUE TO THE DEPARTMENT OF TRANSPORTATION BECAUSE I CAN ONLY IMAGINE THIS IS AN ISSUE THAT'S IMPACTING ALL HYUNDAI EQUUS OWNERS. IT IS ALSO CONCERNING THAT NO ONE SEEMS TO HAVE THE RIGHT ANSWER ON HOW TO CORRECT THE PROBLEM. ATTACHED YOU WILL FIND PAPERWORK FROM MY MOST RECENT ATTEMPT TO GET THE WHEELS ALIGNED . I AM HOPEFUL YOU CAN HELP BRING LIGHT TO THIS ISSUE AND HELP CORRECT AND FUTURE PROBLEMS FOR ALL EQUUS OWNERS.

SERVICE BRAKES
THE BRAKE PEDAL TRAVEL IS VERY LONG. I MUST BEGIN THE STOPPING PROCESS MUCH EARLIER THAN PREVIOUS. THE DEALER DIAGNOSED A FAILED HECU. THE VEHICLE IS ONLY A FEW MILES AND ONE MONTH OUT OF WARRANTY. HYUNDAI MOTOR AMERICA HAD AN INSPECTION CAMPAIGN FOR GENESIS HECU UNITS, BUT NOT EQUUS. HOW CAN THE HECU BE PROPERLY INSPECTED WITHOUT DISASSEMBLING THE UNIT? HYUNDAI SHOULD REPLACE THE FAILED HECU.

SERVICE BRAKES
I WAS DRIVING THE HARD AND I HAD TO COME TO A STOP ON THE HIGHWAY. ALL OF A SUDDEN MY BRAKES TURNED SPONGY AND I SWERVED TO MISS A CAR. I HAVE HAD THE MASTER CYLINDER REPLACED THINKING THAT WAS THE ISSUE BUT IT WAS STILL SPONGY. I THEN NOTICED THE RECALL ON THE GENESIS AND I CONTACTED HYUNDAI. I ASKED DID THE RECALL AFFECT THE EQUSS SEEING HOW THEY ARE THE SAME PART NUMBERS. THEY TOLD ME NO AND IT DIDN'T FALL UNDER THE WARRANTY EITHER. THEY SAID I WOULD HAVE TO PAY AROUND $2800 TO HAVE IT FIXED. I DON'T UNDERSTAND HOW THE SAME PART GOES BAD ON 2 DIFFERENT CARS BUT THE RECALL ISN'T FOR THE EQUUS IN THE SAME YEARS AS THE RECALL ON THE GENESIS.

DRIVER BEHIND ME ALERTED THAT MY BRAKES WORKED BUT MY BRAKE LIGHTS DID NOT WORK. HE INDICATED THE POTENTIAL FOR SERIOUS ACCIDENT ON THE NATION'S HIGHWAYS. DEALER REPLACED BRAKE HARNESS DIODE Z06. AGAIN ON 20MAY2014, THE SAME THING HAPPENED. THIS TIME, DEALER REPLACED DIODE Z01. THERE WAS NO AUDIBLE OR VISUAL WARNING ON THE DASH ALTHOUGH VEHICLE PERFORMS A "SYSTEM CHECK" AT STARTUP AND WARNS OF MINOR ALERTS LIKE LOW TIRE PRESSURE. I AM AFRAID TO DRIVE THE VEHICLE AS I AM A RETIRED PERSON AND I MUST DEPEND ON THE SAFETY FEATURES OF MY CAR. TWO LETTERS TO HYUNDAI HQ HAVE NOT PRODUCED RESULTS. INTERNET SEARCHES REVEAL THAT THIS PROBLEM HAS EXISTED WITH HYUNDAI FOR MANY YEARS. A PERMANENT FIX IN THE FORM OF A RECALL IS REQUIRED. OR, REFUND THE PURCHASE PRICE SO THAT OWNERS CAN BUY A SAFE CAR. ... UPDATED 10/27/14 *BF UPDATED 11/13/14 *BF UPDATED 7/28/2015 *JS *TR
