2017 Hyundai Elantra Speed Control & Cruise Problems

The engine of my vehicle malfunctioned. It is available for inspection upon request, it will have to be towed. The problem put myself and others in danger as the car stopped as I was driving in the middle of a 3-lane highway in the far left lane. Others were put in danger as they had to swerve to avoid hitting me. That itself could have caused a chain collision as other vehicles in the middle lane were put in danger. I was also at risk to get rear ended as one might not notice that my speed has stopped increasing. I have already had it towed to a local Hyundai dealership and auto shop; both said it needs a new engine. Towing receipt is shown below. I had no warning lights on my dash prior to the engine failure. A battery light and check engine light appeared after I was able to safely pull to the side of the road and try to start the car again.

Since buying my vehicle new, it has had three ignition coils fail at different times. The car begins to shudder, rough idle, not accelerate and all of a sudden just will not respond to giving it gas. This happens at any speed therefore it is a danger especially entering or exiting highways or switching lanes. It has been unpredictable. The check engine light does come on some of the time as this problem is occurring, not before. The dealer replaced the first two coils (51, 576 miles and 56, 446 miles) under the warranty. The third coil replaced (78, 391 miles), they would not cover under warranty, nor would they replace the 4th coil as a precaution.

Originally I had gottem my oil changed at the Hyundai dealership 2 months before . The car was turning off on me while driving making slow turns or slowing down to 5mph or less. Then my car broke down on me and wouldnt turn on. Mechanic was saying there was no oil in and it created a sludge in the engine basically ruining the car. My check oil light never came on, and the oil was just recently changed so this shouldve been apart of the recall where similar issues happened.

THE ISSUE HAS HAPPENED WHILE MY VEHICLE HAS BEEN STATIONARY AND IN MOTION, ON A CIY STREET, ON A HIGHWAY AND WHILE TURNING. THE CHECK ENGINE LIGHT COMES ON AS THE CAR SHAKES. IF I'M IN MOTION, THE LIGHT WILL STAY ON WHILE MY FOOT IS ON THE ACCELERATOR, TURN OFF WHEN I TAKE IT OFF THE ACCELERATOR AND COME BACK ON WHEN IT REACHES 1RPM'S. IF I'M STOPPED IT WILL JUMP FORWARD WHEN I PRESS THE GAS TO ACCELERATE (THE WHOLE TIME THE CHECK ENGINE LIGHT IS ON). WHILE I'M STATIONARY, IT WILL STAY ON WHILE IT'S AT 1RPM'S OR BELOW. I HAVE GONE TO THE DEALER A COUPLE TIMES ALREADY TO GET TO THE BOTTOM OF IT. THE FIRST TIME THEY TOLD ME IT HAD TO DO WITH MY SPARK PLUGS SO I DID THE SERVICE TO GET THAT TAKEN CARE OF. THE SECOND TIME I WENT THEY TOLD ME THEY COULDN'T FIND ANY CODE TO INDICATE A PROBLEM. HERE WE ARE AGAIN AND I'M HAVING THE SAME ISSUE. THIS IS DANGEROUS AND NEEDS TO BE ADDRESS AS I'VE CURRENTLY READ MANY 2017 HYUNDAI ELANTRA OWNERS ARE HAVING THE SAME ISSUE. I DON'T SEE THE BENEFIT OF BRINGING IT TO THE DEALER AGAIN IF I'M JUST GOING TO PAY FOR A SERVICE THAT ISN'T GOING TO RECTIFY THE PROBLEM AND THEY CONTINUE TO SAY THERE IS NO PROBLEM. I DO HAVE VIDEO TO SHOW THE PROBLEM.

2017 HYUNDAI ELANTRA CAR STARTED STALLING AT RED LIGHTS AND WHEN STOPPING. ALMOST CRASHED TWICE. IT STARTS BACK UP. IT STARTED 10\12\20. IT HAPPENED A FEW TIMES AND THEN THE CHECK ENGINE LIGHT CAME ON WITH CODE P3006. ABOUT 20 MILES IT WENT OFF. THIS IS VERY DANGEROUS AND NEEDS TO BE FIXED. A LOT OF PEOPLE IS COMPLAINING ABOUT THE SAME ISSUE. IT NEED TO BE RECALLED AND REPAIRED.

IN FEBRUARY 2020, MY CHECK ENGINE LIGHT CAME ON AFTER MY CAR BEGAN TO SHAKE VIOLENTLY AND LOSE SPEED AS I DROVE ON THE CITY STREETS AND HIGHWAYS.THE SERVICEMAN REPLACED THE COILS IN MY CAR. WITHIN A WEEK, MY CAR STARTED TO SHAKE AND LOSE SPEED AGAIN. I TOOK IT BACK TO THE DEALERSHIP WHERE THEY "FIXED" IT AGAIN TO NO AVAIL. IN EARLY MARCH, MY CAR WAS STILL EXPERIENCING THE SAME PROBLEMS: SHAKING VIOLENTLY AND LOSING SPEED AS I DROVE ON BOTH THE HIGHWAY AND ON CITY STREETS. I CHOSE TO TRY A DIFFERENT SERVICE CENTER. THEY ATTEMPTED TO FIND A PROBLEM WITH MY CAR BY RUNNING THE CODES, BUT HE SAID THAT NOTHING POPPED UP ON THE SCREEN. I TOLD HIM THAT MY CHECK ENGINE LIGHT FLASHES ON AND OFF WHEN I PUT MY FOOT ON AND OFF OF THE ACCELERATOR. HE SENT ME ON MY WAY WITHOUT FIXING MY CAR, BUT HE TOLD ME TO BRING MY CAR BACK INTO THE SERVICE CENTER WITHOUT SHUTTING OFF MY CAR AS SOON AS THE CHECK ENGINE LIGHT COMES ON THE DASHBOARD. HE TOLD ME THAT THIS WAS IMPORTANT, BECAUSE IT WOULD HELP THEM BE ABLE TO DETECT THE ISSUE. WITHIN 15 MINUTES OF PULLING OFF OF THE PARKING LOT, MY CHECK ENGINE LIGHT FLASHED BACK ON AND MY CAR BEGAN TO SHAKE AND LOSE SPEED AGAIN. I TURNED AROUND IMMEDIATELY AND TOOK MY CAR BACK. THEY FLUSHED OUT THE FUEL LINE SYSTEM. WITHIN TWO WEEKS, I BROUGHT MY CAR BACK FOR THE SAME THING, BUT THE SERVICEMAN TOLD ME THAT HE COULD NOT FIND ANY ISSUES SINCE THE COMPUTER SHOWED NO ISSUES. EVERY TIME I TAKE MY CAR INTO A HYUNDAI REPAIR CENTER, THEY TELL ME THAT THEY CANNOT DETECT ANY ISSUES WITH MY CAR, ALTHOUGH I TELL THEM THAT MY CAR BEGINS TO SHAKE AND LOSE SPEED RANDOMLY. IT IS NOW SEPT. 2020, AND I AM STILL HAVING THE SAME ISSUES. I AM SCHEDULED TO TAKE MY CAR INTO A NEW HYUNDAI SERVICE CENTER IN A NEW STATE. THIS IS A DANGEROUS CAR PROBLEM THAT THREATENS THE SAFETY OF ME AND OTHER DRIVERS ON THE ROAD. HYUNDAI NEEDS TO TAKE ACTION NOW!

I HAVE A 2017 HYUNDAI ELANTRA. STARTED HAVING PROBLEMS WITH PICKING UP SPEED RPMS JUMPING AND FEELING LIKE THE CAR DOESN'T WANT TO GO. THIS STARTED AT 7,000 MILES AND I BOUGHT THE CAR BRAND NEW OFF THE LOT IT HAS BEEN IN OVER 8 TIMES FOR THIS ISSUE AND HAVE BEEN TOLD THAT NOTHING IS WRONG WITH THE CAR OR THAT BECAUSE MY CAR IS NOT THROWING CHECK ENGINE LIGHTS THEY WONT FIX IT UNDER WARRANTY, OR I'M NOT USING A HYUNDAI APPROVED GAS STATION SO THIS IS WHY I'M HAVING PROBLEMS WITH THE CAR, NOW AT 29,000 MILES STILL HAVING PROBLEMS ITS THE WORST ON THE EXPRESSWAY IN STOP AND GO TRAFFIC.NOW I WENT TO HAVE MY OIL CHANGED AND FOUND OUT I WAS LOW ON 2 QUARTS OF OIL AND MY SPARK PLUGS HAVE OIL ON THEM ONCE AGAIN THE CAR HAS TO GO BACK TO THE DEALERSHIP, I WAS MADE FULLY AWARE OF WHAT COULD HAPPEN IF THE ENGINE GOES. I JUST REALLY HOPE I'M NOT ON THE EXPRESSWAY WHEN THIS HAPPENS, AT THE BEGIN OF THE YEAR I NOTICED WHEN I WOULD COME TO A STOP MY HEAT WOULD DROP AND BECOME LUKE WARM IT HAS NOW BEEN INTO THE DEALERSHIP 3 TIMES THE THERMOSTAT HAS BEEN REPLACED BUT I HAVE BEEN TOLD THAT THIS IS NORMAL HYUNDAI VEHICLES DO THIS. MY HEAT IS DROPPING AT LEAST 58 DEGREES WHEN IDLING AND MY WINDOW IS HAVING A HARD TIME DEFROSTING UNLESS I'M DRIVING. *TR

TL* THE CONTACT OWNS A 2017 HYUNDAI ELANTRA. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, THE BRAKE PEDAL WAS DEPRESSED BUT WAS FIRM. ADDITIONALLY, THE VEHICLE FAILED TO RESPOND WHEN THE ACCELERATOR PEDAL WAS DEPRESSED. THE VEHICLE WAS TAKEN TO GENE MESSER HYUNDAI (4025 W LOOP 289, LUBBOCK, TX 79407) HOWEVER, THE MECHANIC WAS UNABLE TO DUPLICATE THE FAILURE. THE VEHICLE WAS THEN TAKEN TO AN INDEPENDENT MECHANIC WHERE THE CONTACT WAS NOTIFIED OF NHTSA CAMPAIGN NUMBER: 17V063000 (SERVICE BRAKES, HYDRAULIC) HOWEVER, THE VEHICLE WAS NOT INCLUDED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT INFORMED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 75,000. THE VIN WAS INVALID.

WHILE TRYING TO INCREASE SPEED TO GET ON HIGHWAY THE RPM INCREASED BUT MY CAR WOULD NOT SPEED UP. HAS HAPPENED ON SEVERAL OCCASIONS.

THE CAR IS SLOW ACCELERATE LIKE SOMETHING IS WRONG WITH IT. IT STARTED THE YEAR 2018. THE CARE WAS PURCHASED 2/17/17 WITH 25 MILES ON IT. THE DEALER CLAIMS THEY CAN FIND NOTHING WRONG.

3 OCCURRENCES: LEAVE FROM PARKING SPACE- TURN ON ENGINE- WAIT UNTIL TACHOMETER GOES TO 1- WITH FOOT ON BRAKE, SHIFT INTO D- TACHOMETER REACHES 5 ON SPEEDING ENGINE BEFORE ABLE TO TURN OFF IGNITION. DRIVING VERY SLOW- WITH FOOT ON BRAKE- IN FORWARD TO LARGE PARALLEL PARKING- SPEEDS UP- BRAKES SPONGY- DOES NOT STOP CAR. ONLY HIGH CURB PREVENTS CAR FROM CLIMBING ON SIDEWALK AND GIVING ME TIME TO TURN IGNITION OFF. STOPPING AT TRAFFIC LIGHT ON ROAD WITH A 35 MILE SPEED ZONE. AFTER STOP, BRAKE BECOMES SPONGY, CAR'S WHEELS BEGIN SKIDDING- CAN ONLY TURN OFF IGNITION TO STOP THE CAR. EVERYTHING BACK TO NORMAL WHEN I TURNED IGNITION BACK ON, AS WAS THE CASE WITH THE FIRST AND SECOND OCCURRENCES LISTED ABOVE. VEHICLE WAS STATIONARY IN THE FIRST OCCURRENCE, WAS IN MOTION IN A PARK IN THE SECOND OCCURRENCE AND ON A COUNTY ROAD WITH A SLIGHT TURN TO THE LEFT IN THE THIRD OCCURRENCE.

TL* THE CONTACT OWNS A 2017 HYUNDAI ELANTRA. WHILE DRIVING AT UNKNOWN SPEEDS, THE ACCELERATOR PEDAL WAS APPLIED AND TRAVELED TO THE FLOORBOARD. THE VEHICLE HESITATED AND STALLED WITHOUT WARNING. THE VEHICLE WAS TAKEN TO CARDINALE WAY HYUNDAI (2525 WARDLOW RD, CORONA, CA 92882), BUT THE FAILURE WAS UNABLE TO BE DUPLICATED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. ADDITIONALLY, THE VEHICLE WAS TAKEN TO RIVERSIDE METRO AUTO GROUP (8330 INDIANA AVE, RIVERSIDE, CA 92504), BUT THEY WERE ALSO UNABLE TO DUPLICATE THE FAILURE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 17,000.

MY VEHICLE HAS ACC (ADAPTIVE CRUISE CONTROL) AND, WHEN SET, WILL ACCELERATE AND BRAKE AS NEEDED TO KEEP A CERTAIN DISTANCE FROM THE VEHICLE IN FRONT THAT THE SYSTEM HAS IDENTIFIED VIA THE RADAR AND CAMERA. I HAD AN INSTANCE WHERE THERE WAS A MOMENTARY LOSS OF POSITIVE CONTROL OF THE VEHICLE UNDER CERTAIN CONDITIONS. IN THIS EVENT, IT WAS A HAZY AFTERNOON WITH WET ROADS. I WAS FOLLOWING A VEHICLE ON A ROAD WITH THE ACC SET. THE VEHICLE IN FRONT STARTED A DECELERATION LESS THAN 10MPH/S AND MY VEHICLE AUTOMATICALLY STARTED PROGRESSIVELY INCREASING BRAKING ACTION TO MAINTAIN SEPARATION. 1.5 - 2 SECONDS FOLLOWING; IT APPEARED AS THOUGH THE ABS KICKED IN AND DISCONNECTED/OVERRODE THE ACC WITCH SUBSEQUENTLY STOPPED THE BRAKING ACTION ALL TOGETHER. AS A RESULT MY VEHICLE PROCEEDED TORWARD THE VEHICLE IN FRONT OF ME IN A CRITICAL MOMENT THAT REQUIRED, NOW, EVEN MORE BRAKING ACTION IN CONDITIONS THAT INITIALLY CAUSED THE ABS SYSTEM TO ACTIVATE UNDER NORMAL BRAKING ACTION CONTROLLED BY THE ACC. I WAS AWARE AND HAD NOT LET THE SEMI AUTONOMOUS FEATURES OF MY VEHICLE LULL ME INTO COMPLACENCY. I REACTED QUICKLY AND A COLLISION HAD NOT OCCERED. OTHERS MAY NOT BE SO QUICK TO RESPOND IN A SIMILAR SITUATION. I BELIEVE THE SYSTEM DEACTIVATED AS A RESULT OF THE ABS SHAKING THE BRAKE PEDAL OR CONTROL LINKAGES, WHERE, IN NORMAL OPERATION DEPRESSING THE BRAKE DISCONNECTS THE ACC IF THE SYSTEM STARTS AN UNWANTED ACCELERATION OR THE OPERATOR SIMPLY WANTED TO DISCONNECT THE SYSTEM WITHOUT TOGGLING THE STEERING WHEEL DISCONNECT SWITCH. THIS FEATURE IS AVAILABLE ON ALL LIMITED ULTIMATE 2017 HYUNDAI ELANTRAS.
