What 195 owners told NHTSA about the 2013 Hyundai Genesis Coupe

I ORIGINALLY BOUGHT MY 2013 HYUNDAI GENESIS AS A CERTIFIED PRE-OWNED VEHICLE FROM A DEALER IN GEORGIA. FROM AUGUST 2014 TO PRESENT (AUGUST 2015), THE VEHICLE HAS STALLED/CUT OFF UNEXPECTEDLY ON 8 DIFFERENT OCCASIONS, 7 TIMES WHILE DRIVING AT SPEEDS BETWEEN 5 MPH AND 45 MPH, AND ONCE WHILE SITTING IDLE IN PARK. WHEN STALLING, THE STEERING WHEEL TIGHTENS AND/OR LOCKS WHICH MAKES IT EXTREMELY DIFFICULT TO STEER, THE BRAKES HARDEN WHICH MAKE IT EXTREMELY DIFFICULT TO STOP, AND THE DASH LIGHTS UP WITH VARIOUS SYMBOLS AND INDICATORS MUCH LIKE IT WOULD IF IT ONLY HAD POWER BUT WITHOUT THE ENGINE STARTED. TO GET THE CAR GOING AGAIN, I HAVE TO COME TO A STOP, PUT THE CAR INTO PARK, PUSH THE START/STOP BUTTON, AND THE VEHICLE STARTS AGAIN. ON THE 7TH TIME OF THE CAR STALLING, MY WIFE WAS MAKING A RIGHT HAND TURN WHEN THE VEHICLE CUT OFF. SHE NEARLY PLOWED INTO A VEHICLE THAT WAS STOPPED AT THE LIGHT MAKING A LEFT HAND TURN ONTO THE STREET SHE WAS COMING FROM, AND THEN NEARLY CAUSED A 3 CAR PILE-UP BEHIND HER BECAUSE OF HER UNEXPECTED BRAKING AND SUDDEN LOSS OF CONTROL OF THE CAR. AS OF RIGHT NOW WE ARE AFRAID TO DRIVE THE CAR ANY LONGER. WE HAVE TAKEN IT TO THE DEALER 3 TIMES NOW. ON THE FIRST VISIT BACK IN OCTOBER 2014, THEY CLEANED THE FUEL INJECTION AND THROTTLE BODY, SAYING THAT MAYBE WE HAD A BAD BATCH OF GAS THAT LEFT CARBON DEPOSITS. THEY KEPT OUR CAR FOR A WEEK. THEY WERE UNABLE TO REPLICATE THE PROBLEM. FAST FORWARD SEVERAL MONTHS AND HERE WE ARE AGAIN AT THE DEALER FOR TIME NUMBER TWO. THIS TIME THEY KEPT IT FOR ABOUT 12 DAYS AND DID ANOTHER CLEANING OF THE FUEL INJECTION AND THROTTLE BODY. THEY WERE UNABLE TO REPLICATE THE PROBLEM. LAST FRIDAY, AUGUST 14TH 2014, 3 DAYS AFTER GETTING IT BACK FROM THE DEALER, IT STALLED AGAIN. WE REFUSED TO DRIVE IT THAT WEEKEND, AND I DROVE IT ONLY TO BRING IT BACK TO THE DEALER THIS PAST MONDAY AUGUST 17TH. WE DO NOT FEEL SAFE

AS VEHICLE COMES TO A STOP AND GAS IS PRESSED TO GO AGAIN- CAR ENGINE TURNS OFF. RADIO, AIR, WINDOWS ALL WORK. CAR IS THEN PUT IN PARK AND STARTS RIGHT UP AGAIN. CAR HAS DONE IT 6X SINCE JUNE 14TH. DEALER CAN'T FIGURE WHATS WRONG WITH IT. DIFFERENT PARTS REPLACED- THROTTLE BODY AND PURGE VALVE. CAR STILL DIES AT A STOP. CONCERNING IT WILL HAPPEN IN TRAFFIC ON INTERSTATE WHILE DRIVING WITH MY KIDS IN THE CAR.

MY GENESIS ACCELERATES ON ITS OWN, THIS HAS HAPPENED SEVERAL TIMES, THE LAST TIME IT HAPPENED I WAS ABLE TO GET IT TO THE DEALERSHIP SO THEY COULD SEE IT, THEY TURNED THE CAR OFF & COULD NOT DUPLICATE THE PROBLEM THE 4TH TIME IT HAPPENED THE CAR LUNGED OUT AT A STOP LIGHT & ACCELERATED TO 50 MPH BEFORE I COULD GET IT STOPPED

ENGINE STALLED AGAIN IN END OF MAY, 2015 WHILE THE CAR WAS SLOWING DOWN. IT WAS TRAVELING AT A SPEED BETWEEN 10-20 MPH. THAT WAS THE 4TH TIME WE EXPERIENCED ENGINE STALL IN THE 2.5 YEARS OF OUR OWNERSHIP. WHEN THE ENGINE STALLED, ALL ELECTRICAL SYSTEM SEEM NORMAL - RADIO CONTINUED TO PLAY, AC AND FAN WERE STILL ON. WE ONLY NOTICE IT BECAUSE THE CAR WAS SLOWING DOWN MORE AND THERE WERE NO ENGINE NOISE. AFTER ENGINE WAS STALLED, WE STOPPED THE CAR AND SHIFTED THE SHIFTER BACK TO "PARK". WE WERE ABLE TO START THE ENGINE RIGHT UP AND EVERYTHING WAS FINE AFTERWARD. OUTSIDE WEATHER TEMPERATURE WAS HOT (UPPER 80?S TO 90?S) AT THE TIME. IN THE 4 INCIDENTS, THE ENGINE STALLED WHILE WE WERE ON A FLAT ROAD, INCLINE ROAD, GOING STRAIGHT AND MAKING A RIGHT TURN. IT HAPPENED RANDOMLY AND WE COULD NOT REPRODUCE IT. DEALER HAD TAKEN A LOOK AT THE ISSUE TWICE. NO COMPUTER ERROR CODES WERE FOUND AND THEY COULD NOT REPRODUCE THE STALLING PROBLEM EITHER. *CN

FIRST, THE CAR BEGAN RUNNING ROUGH SOON AFTER PURCHASED IN DECEMBER 2013 WITH 13,000 MILES. TAKEN TO DEALERSHIP TWICE . HAD MISFIRE CODES. WAS TOLD NOT TO USE GAS FROM KROGER. EVEN USING SHELL MID GRADE GAS CAR RUNS ROUGH AND PRONOUNCED STUMBLING UPON HIGHWAY ACCELERATION. SECOND, EXHAUST IS SOOTY AND STAINING REAR BUMPER AND CORRODING THE EXHAUST TIPS. DEALER SAID THE ENGINE (6 CYLINDER) IS HIGH PERFORMANCE AND ALL HIGH PERFORMANCE ENGINES SOOT. HE WOULD NOT WRITE THAT RESPONSE ON REPAIR TICKET. AS A LAY PERSON, CAR APPEARS TO BE RUNNING RICH WHICH IS CAUSING THE SOOT AND ROUGH ENGINE PROBLEMS.

WE WERE AT AN INTERSECTION ON HIGHWAY 1. CARS WERE DRIVING BY AT THE SPEED LIMIT OF 55MPH SO IT WAS IMPORTANT THAT WE ACCELERATE QUICKLY IN ORDER TO TURN LEFT ONTO THE HIGHWAY AND AVOID BEING HIT BY ONCOMING TRAFFIC. *TR WHEN IT WAS TIME TO GO I STEPPED ON THE ACCELERATOR, THE CAR BEGAN TO MOVE AND THEN WE EXPERIENCED ENGINE HESITATION, WHERE THERE WAS A MOMENTARY PERIOD WHERE THE ENGINE DID NOT RESPOND TO ME STEPPING ON THE ACCELERATOR. I REACTED BY STEPPING ON THE ACCELERATOR COMPLETELY TO THE BOTTOM AND STILL HAD NO RESPONSE - WE WERE COASTING. I COMPLETELY BACKED OFF THE ACCELERATOR AND STEPPED ON IT AGAIN WHEN THE ENGINE FINALLY BEGAN TO RESPOND. VEHICLES WERE FAST APPROACHING AND IN THAT MOMENT I FELT SCARED AND LOST TRUST IN MY CAR'S FUNCTIONALITY. EARLIER THAT DAY I ALSO NOTICED THAT WHEN ACCELERATING, WHEN ALREADY MOVING, I NOTICED THAT THE TRANSMISSION FELT LIKE IT WOULD WOBBLE. IT'S DIFFICULT TO DESCRIBE. IT FELT LIKE VERY SUBTLE MOMENTARY LOSSES OF POWER OR ACCELERATION FOLLOWED BY A RECOVERY IN THE ACCELERATION AND THEN REPEATING BUT IN QUICK SUCCESSION. YOU WOULD ONLY NOTICE IT IF YOU OWNED THE CAR. I HAVE NOT BEEN ABLE TO DUPLICATE IT. MAYBE IT WAS THE TRACTION CONTROL SYSTEM BUT BEING UNABLE TO ACCELERATE IN A SITUATION LIKE MINE WAS VERY DANGEROUS.

TWO WEEKS AGO, MY 2013 3.8 V6 GENESIS SEDAN STALLED WHEN I WAS ABOUT TO TURN RIGHT INTO MY DRIVEWAY. BOTH THE STREET AND MY DRIVEWAY HAVE A LITTLE OF AN INCLINE (MAYBE 5 DEGREES). AFTER THE ENGINE STALLED, I NOTICED THE FUEL TANK WAS ON THE NEAR-EMPTY SIDE AND THE RANGE INDICATOR INDICATED THE REMAINING RANGE WAS 40 MILES. I WAS ABLE TO SHIFT THE CAR TO PARK AND RE-STARTED IT TO PULL INTO MY GARAGE. THIS ENGINE STALLED PROBLEM HAD HAPPENED TO MY WIFE TWICE AROUND THE SAME SPOT WITHIN THE LAST SIX MONTHS. WE TOOK THE CAR TO A HYUNDAI DEALERSHIP TO HAVE THEM LOOK IT OVER. THE TECHNICIAN DID NOT FIND ANY FAULT CODES AND THE CAR RAN FINE DURING TEST DRIVE. NO CORRECTIVE ACTIONS WERE PERFORMED AT THE TIME. *TR

MULTIPLE TIMES I HAVE ACCELERATED THE CAR TO GET ONTO THE HIGHWAY, CHANGE LANES QUICKLY,AND MAKE RIGHT ON REDS, ONLY TO HAVE IT LITERALLY DO NOTHING. AT TIMES IT TAKES 2 TO 3 SECONDS BEFORE IT ACCELERATES AND THEN SEEMS TO HAVE A TOUGH TIME SHIFTING THROUGH THE GEARS.AT LOW SPEEDS THE CAR SEEMS TO HESITATE AND SHIFT POORLY. HOPEFULLY THE DEALER CAN DO SOMETHING TO CORRECT THE ISSUE. *TR

IN THE MORNING AROUND 9AM GOING TO WORK ON 405 NORTH. ALL THE SUDDEN I STARTED TO LOSE POWER, ENGINE WAS STILL RUNNING BUT DIDN'T ACCELERATE AT ALL, I CAME TO STOP END UP BLOCKING ON OF RIGHT LANE AND NOTICED ENGINE SOUND WAS UNUSUAL AND STARTED SHAKING A LOT. I CALLED HYUNDAI ROADSIDE ASSISTANCE AND MY CAR WAS PICKED UP AND DROPPED TO A KIRKLAND HYUNDAI DEALER BUT THEY DIDN'T FIND ANYTHING UNUSUAL. SERVICE SHOP PERSONAL CLAIM THAT CAR STARTED RIGHT UP AND DIDN'T FIND ANYTHING FROM DIAGNOSTICS TEST. THIS INCIDENT MAKES ME VERY NERVOUS TO DRIVE THIS CAR. *JS

VEHICLE HESITATES WHEN TRYING TO ACCELERATE IN CITY & HIGHWAY TRAFFIC. I HAVE TAKEN IT TO THE DEALER TWICE AND IT WILL BE THE THIRD TIME TOMORROW. THEY DON'T SEEM TO HAVE A SOLUTION AND TELL ME THAT THE VEHICLE IS LEARNING MY DRIVING HABIT'S. (HOW FUNNY). THIS IS MY 15TH OR SO NEW HIGH LINE VEHICLE. THIS HESITATION IS CAUSING LIFE THREATENING EXPERIENCES. I ALMOST GOT CREAMED, (HIT) SEVERAL TIMES WHILE TRYING TO MERGE ON THE FREE WAY. I SEE I'M NOT THE ONLY ONE WITH THIS PROBLEM. WE NEED HELP. *TR

AUTO HESITATES WHEN ACCELERATED HARD; IT FALLS FLAT ON ITS FACE WHEN CALLED ON TO PERFORM. NOT SURE IF IT IS ENGINE OR TRANSMISSION (WRONG GEAR). I CONSIDER THIS A SAFETY ISSUE BECAUSE ONE CANNOT GET OUT OF THE WAY OF ONCOMING TRAFFIC. TYPICALLY, WHEN ATTEMPTING TO EXIT A SLOW MOVING (30-40 MPH) TRAFFIC LANE INTO FAST LANE, THE CAR TEMPORARILY STALLS PUTTING DRIVER AT RISK OF BEING HIT IN REAR. THIS ALMOST ALWAYS HAPPENS WHERE CAR IS MOVING AS SLOW SPEED, BUT RARELY FROM A DEAD STOP. *TR

WHEN ACCELERATING AT LOW SPEEDS (SPECIALLY ON FREEWAYS) THE TRANSMISSION EXPERIENCES A DELAYED SHIFT BETWEEN GEARS 3-5. THE SHIFT DELAY TYPICALLY LASTS 2-3 SECONDS. THIS CAUSES THE RPMS TO INCREASE TO 3000-4500. DRIVER HAS TO HEAVILY ACCELERATE TO ENABLE THE TRANSMISSION TO UP SHIFT. IN ADDITION, THIS CAUSES THE REAR TIRES TO SPIN IF ESC IS TURNED OFF MAKING IT DIFFICULT TO CONTROL THE VEHICLE. VEHICLE LUNGES FORWARD SUDDENLY AS IF THE COMPUTER GOT THE REQUIRED INFORMATION TO ACCELERATE THIS CAUSES SUDDEN FORWARD MOMENT.CAR WAS TAKEN TO THE DEALER , THEY FOUND NO ISSUES. *TR
