2010 Hyundai Genesis Coupe Speed Control & Cruise Problems

While driving, throttle stuck wide open. It was like I was flooring the gas pedal. I managed to pull over and stop vehicle. I restarted and was able to drive home.

TL* THE CONTACT OWNS A 2010 HYUNDAI GENESIS. WHILE ATTEMPTING TO ACCELERATE FROM A STOP LIGHT, THE VEHICLE WENT INTO IDLE MODE. AFTER THE THIRD ATTEMPT OF DEPRESSING THE ACCELERATOR PEDAL, THE VEHICLE ACCELERATED RAPIDLY. THE FAILURE OCCURRED INTERMITTENTLY. THE VEHICLE WAS TAKEN TO ROUND ROCK AUTO GROUP (2301 N INTERSTATE 35, FRONTAGE RD #300, ROUND ROCK, TX, 78664 855 996-3127) WHERE THE PEDAL ASSEMBLY DASH ACCELERATOR WAS REPLACED, BUT THE FAILURE RECURRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 48,031. *TR..*BF *DT*JB

MY 2010 HYUNDAI GENESIS WAS RECALLED FOR A DEFECTIVE FAULTY BREAK SWITCH IN 2014 AND THE REQUIRED SERVICE WAS PERFORMED 7/30/15. THE FOLLOWING DAY I ENGAGED THE CRUISE CONTROL AT 75 MPH BUT ALMOST REAR ENDED THE CAR IN FRONT OF ME BECAUSE THE INTEGRATED SPEED CONTROL DID NOT ACTIVATE. THE CRUISE CONTROL ALSO TURNED COMPLETELY OFF AT TIMES. I'VE RETURNED THE CAR TWICE TO REMEDY THE PROBLEM AND WAS TOLD THEY COULD NOT FIND A SOLUTION AND HAVE REQUESTED ASSISTANCE FROM HYUNDAI. I WAITED ALMOST 2 MONTHS WITH NO WORD FROM HYUNDAI AND FINALLY WENT TO THE DEALERSHIP ON 9/22/15 AND WAS TOLD THEY WERE STILL WAITING FOR INSTRUCTION FROM HYUNDAI AND THEY NOW HAVE A SECOND CAR WITH THE SAME PROBLEM. I FEEL THIS IS VERY DANGEROUS AND WANT TO POST THIS LISTING BECAUSE I BELIEVE LIFES ARE AT STAKE AND OWNERS OF THESE VEHICLES WILL MORE THAN LIKELY BE TICKETED FOR CAUSING ACCIDENTS AND, WORSE CASE SCENARIO, BE CHARGED WITH VEHICULAR MANSLAUGHTER.

WHILE DRIVING THE CAR, THE CAR SPEEDS UP ON ITS OWN WITHOUT ME PUSHING THE ACCELERATOR. THE CAR ALSO HAS REV HANG AND THE RPMS RISE BY ITS SELF AND STAYS THEIR. USUALLY BETWEEN 6500RPM. I HAVE TO PRESS THE BRAKE IN ORDER FOR THE RPMS TO DROP SO ITS DOESN'T BLOW THE MOTOR. *TR

ON 4/18/13 AT 2125 HOURS, UNIT 1 WAS TRAVELING EASTBOUND IN LANE TWO OF NORTHERN AVENUE APPROACHING NORTH 59TH AVENUE. UNIT 2 WAS IN LANE TWO OF EASTBOUND WEST NORTHERN AVENUE STOPPED FOR A RED LIGHT AT THE INTERSECTION WITH NORTH 59TH AVENUE. UNIT 2, A BUS, WAS PARKED IN BUS PULL OUT JUST EAST OF NORTH 59TH AVENUE ON WEST NORTHERN AVENUE WITH THE DRIVER OF THE BUS NOT IN DRIVER SEAT BUT STANDING IN BUS. ACCORDING TO DRIVER OF UNIT 1, WHILE UNIT 1 WAS SLOWING TO STOP BEHIND UNIT 2 THE ENGINE OF UNIT 1 BEGAN RACING AND DID NOT STOP EVEN AS THE DRIVER OF UNIT 1 PRESSED THE BRAKES. UNIT 1 STRUCK UNIT 2 IN THE REAR AT LEAST TWICE PUSHING UNIT 2 INTO INTERSECTION. UNIT 2 DRIVER STATED AFTER BEING HIT AT LEAST TWICE BY UNIT 1, UNIT 2 CROSSED INTERSECTION AND STOPPED IN FRONT OF THE BUS TO GET OUT OF THE WAY OF UNIT 1. UNIT 1 ALSO CROSSED THE INTERSECTION OF NORTH 59TH AVENUE AND UNIT 1 STRUCK REAR END OF UNIT 3. DRIVER SIDE PASSENGER OF UNIT 1 WAS TREATED BY GLENDALE FIRE LT157/B-SHIFT AND TRANSPORTED TO HOSPITAL BY SOUTHWEST AMBULANCE B-SHIFT ON INCIDENT NO. 13-121969 AND FOUND TO HAVE FRACTURED LEFT HUMERAL (ELBOW) BY DOCTOR F CONJURSI, MEDICAL RECORD 1173763. DRIVER OF UNIT 1 WAS ISSUED CITATION NO. 862591 FOR ARS 28-701.A AND ARS 28-3151.A.

IT DOES NOT SHIFT PROPERLY CAUSING IT TO DECREASE OR INCREASE SPEED WITHOUT PRESSING THE GAS PEDAL. THE PROBLEM ALSO CAUSES THE VEHICLE TO EXCEED RECOMMENDED RPM LEVEL WHICH CAUSES THE VEHICLE TO GET STUCK IN ONE GEAR AND MAKES IT DIFFICULT TO STOP THE VEHICLE. THIS ISSUE HAS CAUSED INSTANCES WHERE I HAVE HAD TO SWERVE OFF THE ROAD TO AVOID COLLISION. *TR

TL* THE CONTACT OWNS A 2010 HYUNDAI GENESIS COUPE. THE CONTACT STATED THAT WHILE ATTEMPTING TO START THE VEHICLE BY ENGAGING THE PUSH-TO-START BUTTON, THE VEHICLE ERRONEOUSLY ACCELERATED. THE CONTACT WAS NOT APPLYING THE BRAKES AT THE TIME NOR WAS THE VEHICLE SHIFTED INTO DRIVE. THE CONTACT CRASHED INTO A GLASS GARAGE DOOR. THE CONTACT SUSTAINED MINOR CUTS AND BRUISES FROM THE IMPACT. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER BUT WAS NOT REPAIRED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE AND CURRENT MILEAGES WERE 63,510.

2010 HYUNDAI GENESIS. CONSUMER STATES BRAKE/ ACCELERATOR ISSUES WITH VEHICLE *TGW THE CONSUMER STATED SIX TO EIGHT MONTHS AGO, HE BEGAN TO EXPERIENCE A TROUBLING PROBLEM WITH THE BRAKE /ACCELERATOR, WHICH MANIFESTED ITSELF BY FREQUENTLY CAUSING THE VEHICLE TO JUMP AHEAD OR JERK FORWARD WHEN SHIFTING HIS FOOT FROM THE ACCELERATOR TO THE BRAKE PEDAL USUALLY WHEN INTENDING TO COME TO A STOP. AT TIMES, THE TENDENCY FOR THE VEHICLE TO CONTINUE TO MOVE FORWARD REQUIRED AN IMMEDIATE STRONG BRAKING EFFORT TO OVERCOME THAT TENDENCY AND TO ACTUALLY STOP THE VEHICLE. THE CONSUMER STATED HE HAD ONLY EXPERIENCED THE PROBLEM, WHILE IN FORWARD GEAR. *JB

CAR WILL NOT ACCELERATE PROPERLY IN 1ST & 2ND GEAR AND TENDS TO WANT TO STALL WHEN REACHING A CERTAIN RPM; CAR WILL NOT GO BEYOND 40 MPH; CHECK ENGINE LIGHT COMES ON; UNABLE TO DETERMINE WHEN THE DEFECT IS ABOUT TO OCCUR MAKING THE CAR UNRELIABLE AND UNSAFE TO DRIVE; DEFECT OCCURS WILL VEHICLE IS IN MID-OPERATION WHILE DRIVING ON ROAD REGARDLESS OF SPEED. DEFECT(S) HAVE RESULTED IN SEVERAL NEAR COLLISION EXPERIENCES, SINCE CARS BEHIND VEHICLE HAVE ALMOST REAR-ENDED VEHICLE AS THEY DID NOT EXPECT THE CAR TO DECELERATE WITH NO BRAKE LIGHT INDICATION OF THE VEHICLE SLOWING DOWN AND IS THEREFORE A DANGER TO DRIVE. DRIVER UNABLE TO SAFELY MERGE WITH TRAFFIC ON MAJOR HIGHWAYS AS THE VEHICLE DOES NOT ACCELERATE PROPERLY AND WILL NOT GO FASTER THAN 40 MPH, MAKING IT IMPOSSIBLE TO MERGE SEAMLESSLY WITH TRAFFIC THEREBY PLACING DRIVER AND DRIVERS OF OTHER VEHICLES IN DANGER AND SAFETY RISK. DRIVER UNABLE TO USE SIDE-ROADS AS AN ALTERNATE MEASURE, AS CAR DOES NOT ACCELERATE PROPERLY AND TENDS TO WANT TO STALL WHEN PULLING OFF IN 1ST AND 2ND GEAR RESULTING IN CARS BEHIND VEHICLE ALMOST REAR-ENDING VEHICLE. THREE ATTEMPTS HAVE ALREADY BEEN MADE TO REPAIR THE DEFECT, YET DEFECT CONTINUES TO OCCUR. *TR

ONE OF MY AUTOMOTIVE FORUM MEMBER EXPERIENCED A SERIOUS SUDDEN ACCELERATION ISSUE WITH HIS HYUNDAI GENESIS 2 DOOR CAR, 2010 MODEL. THE ISSUE WAS BELIEVED TO BE CAUSED BY VDC(VEHICLE DYNAMIC CONTROL SOFTWARE) THAT HYUNDAI MOTOR IN SOUTH KOREA ADMITTED BUT REFUSED TO DO ANY ACTION AGAINST THIS ISSUE. THE HYUNDAI CAR, GENESIS, CAN BE ACCELERATED SUDDENLY WITHOUT PRESSING THE ACCELERATION PEDAL. THE ENGINE RPM WAS RISEN UPTO 6,000 RPM WITHOUT PRESSING THE PEDAL AND THE RPM NEVER DROPPED AGAIN. HYUNDAI R&D CENTER FOUND THE CAR HAD DIFFERENT SIZE OF WHEEL AT THE FRONT SIDE. THE OWNER THEN WITHDREW THE COMPLAINT AGAINST THE HYUNDAI MOTOR INC IN SOUTH KOREA. BUT I WANT NHTSA NEED TO INVESTIGATE THIS ISSUE BECAUSE OTHER DRIVERS IN USA CAN EXPERIENCE THE SAME SAFETY ISSUE. THIS MIGHT CAUSE FATAL ACCIDENTS IF THE FRONT TIRE LOSE AIR PRESSURE. THE HYUNDAI MOTOR SEEMS TO HIDE THIS ISSUE WITHOUT DOING RECALLS. *TR

WHAT I HAD BELIEVED TO BE SOMEWHAT OF A NUISANCE PROBLEM HAS NOW BECOME A VERY CRITICAL PROBLEM. A COUPLE OF TIMES AFTER PURCHASING THIS HYUNDAI GENESIS COUPE 2.0 WHILE TRYING TO NORMALLY ACCELERATE, THE CAR VIRTUALLY DIED. ACCELERATION FLAT SPOT. SOMEWHAT SIMILAR TO THE OLD CARBURETED CARS. VERY INFREQUENT, HOWEVER, THE OTHER DAY LOSING ACCELERATION ALMOST CAUSED A MAJOR ACCIDENT. VERY CLOSE. *TR
