2017 Hyundai Elantra

MY CAR HAD RECENTLY BEGAN TO SHAKE AND BUCK VIOLENTLY WHILE DRIVING WITH NO WARNING LIGHTS OR INDICATORS AT 38,000 MILES. THREE WEEKS AGO BEFORE A REGULAR MAINTENANCE APPOINTMENT AT MY HYUNDAI DEALERSHIP WHERE I BOUGHT THE !CAR, AS I TURNED OVER THE IGNITION AND ACCELERATED THE CAR BEGAN TO BUCK AND SHAKE VIOLENTLY. AS I PRESSED THE GAS, THE CAR WOULD NOT ACCELERATE. I WAS IN THE MIDDLE OF TRAFFIC IN WASHINGTON, D.C. SO ONCE I WAS ABLE TO SAFELY MOVE OVER, I TURNED THE CAR OFF AND BACK OVER. NO SHAKING AND CONTINUED AS NORMAL. ONCE I TOOK THE CAR IN THE FOLLOWING WEEK, I WAS TOLD EVERYTHING WAS FINE AND MADE SURE TO MENTION THE SHAKING AND BUCKING AND WAS TOLD THAT THEY DIDN'T SEE ANYTHING. THE NEXT DAY FOLLOWING SERVICE AND RECEIVING MY CAR BACK, MY CAR BEGAN TO SHAKE VIOLENTLY AGAIN. STILL NO WARNING LIGHT INDICATOR. I RETURNED THE CAR TO THE MECHANIC WHERE MY COIL PACKS WERE UPDATED (I BOUGHT MY CAR MARCH 2017 AND WAS NEVER TOLD ABOUT ANY RECALLS ON COIL PACKS THAT RELEASE LATE 2017 UNTIL THIS MOMENT). ONCE I RECEIVED MY CAR BACK I WAS INFORMED THAT EVERYTHING WAS OKAY. WELL IT WAS NOT. THE NEXT DAY I'M DRIVING MY CAR A SHORT DISTANCE WHEN TWO HARD SHAKES HAPPENED. ONE SOUNDED LIKE TWO METAL PIECES COLLIDING. I PULLED OVER AND TURNED THE CAR OFF AND BACK OVER. THE MALFUNCTION INDICATOR LIGHT IS NOW PERMANENTLY ON. I HAD TO HAVE MY CAR TOWED AND NOW BEING TOLD IT COULD BE THE TRANSMISSION BUT NO UPDATES. SERIOUSLY UNSAFE AND COULD'VE NOW BEEN IN MULTIPLE ACCIDENTS ALTHOUGH I'VE REGULARLY SERVICED AT THE DEALERSHIP I PURCHASED MY CAR.

I EXPERIENCED THE CAR IDLING ROUGH WHILE IN PARK AND SOUNDING LIKE IT WANTED TO DIE OUT. I TOOK TO DEALER AND THEY REPLACED AN IGNITION COIL.THE CHECK ENGINE LIGHT CAME ON. CHECK ENGINE LIGHT JUST CAME ON AGAIN YESTERDAY...TOOK IT TO AUTOZONE AND THEY TOLD ME IT WAS THE IGNITION COIL AGAIN. THIS WILL THE 2ND TIME TO HAVE IT FIXED ON MY 2017.SEEMS LIKE HYUNDAI VEHICLES HAVE A TON OF ISSUES WITH IGNITION COILS. AFTER I GOT MY CAR BACK IT VIOLENTLY SHOOK AND CHECK ENGINE LIGHT CAME ON. I WAS ON THE HIGHWAY AND THE SPEED STARTED TO DECREASED. I REACHED OUT TO HYUNDAI CORPORATION ABOUT REPLACEMENT VEHICLE . I STILL HAVE NOT HEARD ANYTHING. I AM NOT THE ONLY ONE WITH THE FAULTY IGNITION COILS.

TL* THE CONTACT OWNS A 2017 HYUNDAI ELANTRA. THE CONTACT STATED WHILE DRIVING AT 40 MPH, THE VEHICLE SHUDDERED EXCESSIVELY AND STALLED WITH THE CHECK ENGINE WARNING LIGHT ILLUMINATED. THE ACCELERATOR WAS RELEASED AND THE VEHICLE OPERATED AS DESIGNED. THE VEHICLE WAS TAKEN TO ROGERS AUTO GROUP CHICAGO LOCATED AT (2720 S MICHIGAN AVE, CHICAGO, IL 60616) WHERE THE VEHICLE WAS DIAGNOSED WITH A DEFECTIVE UNKNOWN SENSOR. THE VEHICLE WAS REPAIRED HOWEVER, THE FAILURE RECURRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 32,000.

AS OF LAST WEEK, MY TRANNY SEEMED LIKE IT WAS SLIPPING. SOMETIMES IT DID , OTHER TIMES IT JERKE.. ANYWAY, IT SNOWED HERE IN UPSTATE NY. I AMAL OVER THE ROAD. MY TIRES SEEM OK. BRAKES ARE GRINDING. CARS ONLY A YEAR OLD SOON. I HAVE 3 CHILDREN IN THE CAR. I AM ALWAYS IN MOTION. GETTING SCARED TO DRIVE. IT FEELS LIKE THE TIRES THOUGH TOO.. WHAT KIND OF TIRES DOES THIS CAR HAVE.. DOES IT HAVE ALLSEASONS? DOESNT FEEL LIKE IT. ANYWAY THIS SHOULD NOT BE HAPPENING.. HELP.

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.

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.
