TOO DANGEROUS TO DRIVE AROUND.

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.

THIS WAS THE DATE OF THE FIRST INCIDENT, ANOTHER INCIDENT HAPPENED THREE MONTHS LATER. WE WERE JUST DRIVING ALONG AND THE AIR SUSPENSION SYSTEM FAILED AND THE WHOLE CAR, MOSTLY THE FRONT DROPPED A NUMBER OF INCHES, WE COULD BARELY DRIVE HOME AND HAD TO HAVE VEHICLE TOWED, SEEMS TO BE A VERY UNSAFE ITEM. THE FIRST TIME IT WAS THE PASSENGER SIDE, SECOND TIME IT WAS THE DRIVER SIDE.I CONTACTED HYUNDAI, AND WANTED THEM TO BUY BACK THE VEHICLE, AS I HAVE HAD NUMEROUS OTHER SMALL ISSUES GO WRONG, BUT THIS SUSPENSION PROBLEM FEELS VERY UNSAFE AND ACTUALLY MAKES ME CONCERNED WHEN I DRIVE,THEY REFUSED TO BUY IT BACK. *TR
