When the car gets wet, it sends my dashboard lights flashing, and I’m able to put the car in gear without stepping on the brake, I brought it to numerous of Honda dealerships and other mechanical shops, and they are undetermined to find the cause
The HECU has been malfunctioning in my car for over a year now. It is an open recall for my make, model and year of car. I took it to Bob Rohrman Indy Hyundai and they diagnosed the failed part. This part affects my ABS. There are currently two warning lights on one for the ECS which is the traction control stabilizer and the ABS light is on. Meaning the use of the breaking system is limited and not working properly. I have asked the corporate Hyundai to uphold the recall warranty but I was advised they would not cover this because my vehicle has a rebuilt title. I drive my vehicle on a daily basis and I’m terrified of my brakes going out. The corrosion from the fluid is what causes the HECU to malfunction and it is so scary to think about. This problem was diagnosed and first reported to my his dealership on 6/23/2022.
The car accelerates itself randomly. It’s happened with a lot of Genesis’s of this generation. Almost crashed due to it. Very unsafe. Gave the vehicle to a friend and the problem reoccurred and he captured a video that I have
TL* THE CONTACT OWNS A 2011 HYUNDAI GENESIS. WHILE DRIVING APPROXIMATELY 25 MPH, THE CRUISE CONTROL ERRONEOUSLY ACTIVATED AND COULD NOT BE TURNED OFF. WHILE DEPRESSING THE BRAKE PEDAL, THE VEHICLE WOULD SLOW DOWN BUT THE CRUISE CONTROL WOULD NOT DEACTIVATE. AFTER SWITCHING THE TRANSMISSION TO NEUTRAL, THE RPMS IMMEDIATELY INCREASED TO 5,000. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE CRUISE CONTROL MODULE FAILED AND NEEDED TO BE REPLACED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 60,300.
WHEN ACCELERATING WHILE TURNING A CORNER THE ENGINE LOSES POWER COMPLETELY. IN A HEAVY TRAFFIC SITUATION THIS HAS CAUSED NEAR ACCIDENTS AND ONCOMING DRIVERS TO SLAM ON THE BRAKES. VEHICLE BEGINS AT A DEAD STOP. 1/2 WAY THRU THE TURN THERE IS ALWAYS A COMPLETE LOSS OF POWER AND CAR STALLS FOR SEVERAL SECONDS UNTIL POWER RETURNS. THIS HAPPENS EVERY TIME WHILE ACCELERATING AROUND A CORNER. SCARY
MY 2011 HYUNDAI GENESIS ENGAGED IN UNINTENDED SUDDEN ACCELERATION ON 3/9/16 AT 5:35 PM, IN TAMPA, FL, RESULTING IN A CRASH INTO A DWELLING AT 306 WEST FRANCES AVENUE, TAMPA, FL.33607. VEHICLE WAS IN THE PROCESS OF BEING PARKED ON SIDE OF HOUSE WHEN IT ALL OF A SUDDEN ACCELERATED AND APPLYING THE BRAKES FAILED TO STOP IT
ON DECEMBER 22ND, 2015, I WAS DRIVING THE CAR INTO MY PARKING LOT AT MY OFFICE WHEN THE CAR BEGAN TO ACCELARATE ON ITS OWN. THIS IS THE SECOND TIME IN THE LAST 6 MONTHS THAT THE ENGINE HAS ACCELARATED WITHOUT DEPRESSING THE ACCELERATOR AND THEN CONTINUED TO REV HIGHER WHEN THE CAR IS PUT INTO PARK. IF IT WAS NOT FOR SOME QUICK THINKING, I ALMOST WENT INTO A WALL OF THE GARAGE. I IMMEDIATELY CALLED THE HYUNDAI DEALER AND SPOKE TO THE SERVICE MANAGER. HE COULD HEAR THE REVING OF THE CAR. HE ASKED IF I FELT SAFE DRIVING IT TO THE DEALER WHICH I DID. ALL THOUGHOUT THE RIDE, THE CAR CONTINUED TO ACCELARATE ON ITS OWN. WHEN I ARRIVED AT THE DEALER AND TURNED THE CAR OFF, THE CAR STOPPED DOING THIS. THE DEALER KEPT THE CAR FOR 5 WEEKS AND COULD NOT DUPLICATE OR FIND ANY PROBLEMS. I HAVE ASKED TO SPEAK TO SOMEONE AT HYUNDAI TO SEE WHAT THE NEXT STEPS ARE IF IT HAPPENS AGAIN
ON DECEMBER 18, 2015 AT APPROXIMATELY 4:45PM, MY HUSBAND AND I WERE BEGINNING OUR TRIP TO AN EVENT. WE WERE STOPPED AT A STOP LIGHT, ABOUT THE 4TH OR 5TH CAR IN LINE TO TURN LEFT ONTO A MAJOR ROAD. THERE ARE 2 LANES FOR TURNING LEFT AND WE WERE IN THE TURN LANE NEXT TO THE LANE THAT GOES STRAIGHT ACROSS THE MAIN ROAD BECAUSE WE WERE GOING TO HAVE TO MAKE THE FIRST RIGHT ONTO THE INTERSTATE AFTER GETTING ON THE MAIN ROAD. WE HAD ALREADY COME TO A COMPLETE STOP AND HAD BEEN STOPPED FOR PROBABLY A MINUTE OR SO. CARS WERE ALSO STOPPED BEHIND US. IT IS A STEEP HILL, AND WE WERE FACING UPHILL SO HIS FOOT WAS FIRMLY ON THE BRAKES. THEN ALL OF A SUDDEN THE ENGINE JUST STARTED ROARING LIKE IT WAS FULL THROTTLE AND IT TOOK OFF FORWARD AND HIT A NISSAN FRONTIER PICKUP TRUCK IN FRONT OF US. IT WENT UNDER THE TRUCK'S BUMPER AND KEPT PLOWING FORWARD. HE TRIED TO TAKE IT OUT OF GEAR AND IT WOULD NOT GO. WE WATCHED AS THE HOOD KEPT CRUMPLING MORE AND MORE AS WE WERE LIFTING UP THE TRUCK AS WE WERE GOING UNDER IT. THE BACK WHEELS OF THE TRUCK WERE OFF OF THE GROUND. I FINALLY THOUGHT TO REACH OVER AND TURN THE ENGINE OFF. THANK THE LORD, IT SHUT OFF BEFORE ANYONE GOT HURT.
TL* THE CONTACT OWNS A 2011 HYUNDAI GENESIS. WHILE IDLING AT A STOP LIGHT, THE CONTACT'S VEHICLE ACCELERATED AND CRASHED INTO THE REAR OF ANOTHER VEHICLE. THE VEHICLE WAS TOWED TO A DEALER WHERE IT WAS NOT DIAGNOSED OR REPAIRED. A POLICE REPORT WAS FILED AND THERE WERE NO INJURIES. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 38,233.
I WAS DRIVING AT 35 MPH IN THE LANE, THE CAR ON THE LEFT LANE HIT THE REAR BODY AND TIRE OF DRIVER SIDE, BUT THE CAR DIDN'T STOP EVEN AFTER THE IMPACT. AFTER THE COLLISION, I PRESSED VERY HARD ON THE BRAKE PEDAL TO STOP, BUT IT KEPT MOVING, EVEN INCREASED ITS SPEED UP TO 60 MPH, AND TURNED INTO THE DIFFERENT DIRECTION. ALSO THE WHEEL WAS STUCK BY ITSELF AND I WAS NOT ABLE TO TURN ANYWHERE WITH MY HANDS. IT WENT OFF THE OPPOSITE SIDE OF THE ROAD WITHOUT ANY CONTROL. 20 YEARS OLD TOYOTA CAMRY WAS ABLE TO STOP AT THE SPOT OF COLLISION, BUT HYUNDAI GENESIS COULDN'T. THE WHEEL AND THE BRAKE WERE BOTH STUCK AND UNABLE TO BE CONTROLLED AND CRASHED INTO THE ELECTRIC POLE. THE AIR BAG WAS DEPLOYED, AND HYUNDAI GENESIS WAS TOTALED. IN 2014, THE BRAKE RECALL SERVICE WAS RECEIVED TWO TIMES FROM THE DEALER. THERE MUST BE THE MECHANICAL FAILURE IN THE BRAKE, SPEED CONTROL, AND THE WHEEL WHICH CAUSED THIS TOTAL LOSS. I WAS INJURED AND TAKEN BY THE AMBULANCE LATER. I NEVER HAD ANY ACCIDENTS LIKE THIS BEFORE WITH ANY OTHER CARS! *TR
CAR LOSS ALL FORWARD POWER, SPEED DROPPED TO 20 MPH ACCELERATOR HAD NO EFFECT. AFTER PULLING TO SIDE OF ROAD ENGINE WOULD NOT GO ABOVE 2000 RPM IN NEUTRAL. ENGINE LIGHT CAME ON, LIMPED TO DEALER. DEALER DIAGNOSED AS TROUBLE CODE C15, THROTTLE BODY ASSY. DEALER REPLACED THROTTLE BODY, DROVE CAR FOR 50 MILES IN 4 DAYS. NOW HAVE THE SAME PROBLEM, ENGINE LIGHT ON AND NO POWER. THIS IS A VERY DANGEROUS PROBLEM. WILL HAVE CAR TOWED BACK TO DEALER. LOOSING POWER WITH NO WARNING WHILE DRIVING ON THE INTERSTATES OR PULLING OUT INTO TRAFFIC IS DANGEROUS AND SAFETY PROBLEM!!!!!!! *TR
GOT JACKRABBIT YESTERDAY EVENING(APRL. 13 SUNDAY 2014, 6:30PM ). WHEN I TRIED EXIT TO ROADWAY FROM PARKING LOT, MOTOR REV UP BY ITSELF AND BREAK SYSTEM COULD NOT STOPPED VEHICLE COMPLETELY. I COULD HEAR THE SQUEAKING NOISE FROM BREAKS EVEN I PUSH THE BREAK PEDAL DEEP, I STILL WAS IN THE PARKINIG LOT AND COULD STEER ONTO EMPTY PARKING SPACE AND SHIFTED LEVER TO "NEUTRAL" AND RIGHT AFTER THAT, MOTOR RPM JUMPED OVER 6000 WITH LOUD MOTOR NOISE. I SHOT OFF THE MOTOR AND A LITTLE LATER, REIGNITE OVER AND OVER, SAME THING HAPPENED. ABOUT 20 MINUTES LATER, SYMPTOM DISAPPEARED BY ITSELF. I THINK I WAS LUCKY BECAUSE I WAS NOT ON THE HIGHWAY. I VIDEO RECORDED THIS WITH MY SMART PHONE. * JS
TWICE TODAY, WHILE DRIVING IN STOP/GO TRAFFIC, THE CAR FELT AS IF IT WAS ACCELERATING ON ITS OWN. WHEN I TOOK THE FOOT OF THE BRAKE TO GO, THE CAR WOULD JOLT FORWARD ON ITS OWN. HAD TO PRESS THE BRAKE BERY HARD TO MAKE SURE IT WOULDNT GO BY ITSELF. I HAD TO PULL OVER, AFRAID I WOULD HIT CAR. WHEN I PUT IT ON NEUTRAL, THE ENGINE REVVED TO 3000RPMS AND IT STAYED THERE. MY FOOT WAS NOT ON THE GAS PEDAL AT ALL. WHEN I TRIED SHIFTING BACK TO DRIVE, IT JOLTED FORWARD. THE ONLY WAY TO GET IT TO STOP DOING THIS WAS TO TURN THE ENGINE OFF. AFTER THE FIRST TIME, I DROVE ABOUT 30 MIN IN 40MPH TRAFFIC, BEFORE IT DID IT AGAIN. AT TIMES THE CAR FELT LIKE IT DIDNT WANT TO ACCELERATE WHEN I WANTED TO. THEN AS TRAFFIC SLOWED DOWN, STARTED ACCELERATING ON ITS OWN AGAIN. THIS IS NOT THE FIRST TIME THIS HAPPENS. I BROUGHT THE CAR TO THE HYUNDAI DEALERSHIP SEVERAL MONTHS BACK FOR THE SAME ISSUE AND THEY SAID THEY FOUND NOTHING WRONG. SOMEONE NEEDS TO LOOK INTO THIS BEFORE SOMEONE GETS HURT. *TR
WHEN STARTING MY CAR, RPMS JUMPED TO 4 WITHOUT PRESS ANY PEDALS. AND MY CAR WAS SHAKING AND REALLY BIG SOUND FROM ENGINE WHILE ITS ON PARK. AND I SWITCHED TO DRIVE MODE AND SUDDENLY MY CAR MOVE FORWARD BY ITSELF. AND THEN HIT SIDEWALK AND HEATSHIELD GOT DAMAGED. I WENT TO DEALERSHIP. BUT NO PROBLEM FOUND. I WAS REALLY SCARED, I THOUGHT IM GONNA DIE. *TR
OVER THE PAST TWO MONTHS I'VE EXPERIENCED THREE CASES OF UNCONTROLLED ACCELERATION. SPECIFICALLY, AS I'M DRIVING THE CAR BEGINS TO ACCELERATE. I REMOVE MY FOOT FROM THE ACCELERATOR AND THE CAR CONTINUES TO ACCELERATE. AS I STEP ON THE BRAKE THE CAR WILL SLOW DOWN, BUT IT'S "FIGHTING" ME. AS I REMOVE MY FOOT FROM THE BRAKE THE CAR BEGINS TO ACCELERATE AGAIN. IF I SHIFT INTO NEUTRAL WHILE THIS IS HAPPENING, THE RPM'S ON THE CAR INCREASE VERY RAPIDLY. THE ONLY WAY I CAN STOP THIS IS TO TURN THE CAR OFF. I'M NOT USING CRUISE CONTROL AND I HAVE BEEN TRAVELING FROM 35 TO 40 MPH. I CAN'T RECREATE THIS PROBLEM AT WILL AND NEITHER CAN THE DEALER - SO NOBODY AT THE DEALERSHIP HAS ANY IDEA WHAT TO DO. THEY HAVE CONTACTED HYUNDAI WITH NO LUCK. *TR
ON 8/16/11, WHILE DRIVING DOWN A COUPLE OF HILLS ON MY BRAKES, APPROACHING A CAR & STOP SIGN AT AN INTERSECTION A LITTLE OVER 2 BLOCKS AWAY, I PRESSED DOWN HARDER ON THE BRAKE PEDAL TO COME TO A COMPLETE STOP. THE CAR, A NEW, 2011 HYUNDAI GENESIS, WOULD NOT STOP. I CONTINUED TO PRESS HARDER AND HARDER ON THE BRAKE, BUT THE CAR WOULD NOT STOP. IT JUST CONTINUED AT TO MOVE AT THE SPEED I WAS DRIVING DOWN THE HILL, APPROXIMATELY 15-20 MPH. AS A RESULT, THE CAR ROLLED DIRECTLY INTO THE CAR SITTING AT THE STOP SIGN. *TR
