2018 Hyundai Elantra

TL* THE CONTACT OWNS A 2018 HYUNDAI ELANTRA. WHILE DRIVING APPROXIMATELY 30 MPH, THE GLASS SUN ROOF SUDDENLY EXPLODED. THERE WERE NO INJURIES. THE SUN ROOF WAS IN THE CLOSED POSITION AT THE TIME OF THE FAILURE. THE CONTACT INDICATED THAT THE SUN ROOF HAD NEVER BEEN OPENED PRIOR TO THE FAILURE. THE CAUSE OF THE FAILURE WAS NOT DETERMINED. THE MANUFACTURER AND LOCAL DEALER WERE NOT NOTIFIED OF THE FAILURE. ALSO, WHILE OPERATING THE VEHICLE A WARNING MESSAGE SOMETIMES DISPLAYED ERRONEOUSLY, INDICATING THAT THE SUN ROOF WAS OPEN. THE FAILURE MILEAGE WAS 57,928. THE VIN WAS INVALID.

WITH THE STEERING WHEEL TURNED TO ITS FAR RIGHT EXTREME, THE FRONT SUSPENSION EMITS A LOUD CREAKING NOISE WHEN THERE IS AN INCLINE, SUCH AS ENTERING A PARKING LOT ENTRANCE OR DRIVEWAY. THIS IS THE ONLY TIME I HEAR THE CREAKING NOISE. THIS CONCERNS ME BECAUSE I'M AFRAID THE NOISE INDICATES A FAILING OR FAULTY SUSPENSION COMPONENT, WHICH COULD POSSIBLY LEAD TO LOSS OF VEHICLE CONTROL SHOULD THE FAULTY PART FAIL WITH THE VEHICLE IN MOTION.

WHEN ACCELERATING WITH MODERATE TO HEAVY THROTTLE INPUT, THE ENGINE EMITS EXCESSIVE PINGING AND RATTLES NOISES. IT SOUNDS LIKE "SPARK KNOCK". NO MATTER WHAT BRAND OF FUEL OR OCTANE I RUN THE CAR ON, THE ENGINE MAKES THESE PINGING AND RATTLING NOISES. I'VE BROUGHT THE CAR TO THE DEALERSHIP SERVICE DEPT. TWICE SO FAR TO ADDRESS THIS CONCERN. I WAS INFORMED THE FIRST TIME THAT THEY HEAR THE NOISE, BUT CANNOT DIAGNOSE IT BECAUSE THE CHECK ENGINE LIGHT ISN'T ILLUMINATED. ON THE SECOND VISIT, THEY TOLD ME IT IS A NORMAL NOISE FOR THE CAR. HAVING OWNED A HANDFUL OF VEHICLES OVER THE YEARS, THIS NOISE IS INDICATIVE OF SPARK KNOCK. IF THE PROBLEM IS INDEED EXCESSIVE SPARK KNOCK, THIS CAN LEAD TO CATASTROPHIC ENGINE FAILURE, CAUSING SUDDEN LOSS OF ALL POWER. AFTER RESEARCHING THE ISSUE ONLINE AND SPEAKING WITH OTHER OWNERS, IT IS APPARENT TO ME THAT IT IS A FAIRLY COMMON PROBLEM WITH THE 2018 HYUNDAI ELANTRA SEDAN. I WOULD LIKE HYUNDAI TO INVESTIGATE THIS ISSUE AND COME UP WITH A FIX. THIS PROBLEM HAS EXISTED SINCE BRAND-NEW OFF THE DEALER LOT. THE CAR CURRENTLY HAS APPROXIMATELY 4,000 MILES.

TL* THE CONTACT RENTED A 2018 HYUNDAI ELANTRA. THE CONTACT STATED THAT THE FRONT WINDSHIELD HAD RAINBOW STREAKS ON 45 PERCENT OF THE GLASS. THE DASHBOARD AND STEERING WHEEL WERE REFLECTED ON THE GLASS, WHICH OBSTRUCTED THE CONTACT'S VIEW. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE LOCAL DEALER WAS NOT CONTACTED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS 179,012.*BF . CONSUMER STATED REFLECTION OF THE WINDSHIELD OBSTRUCTED DRIVER'S VIEW AND IS NOT SAFE.*JB

I BOUGHT THE CAR BRAND NEW WITH 20 MILES. I AM THE ONLY OWNER. WHEN I BOUGHT I NOTICED THE ACCELERATION ISSUE. I INFORMED THE DEALER 10 DAYS OWNING IT THERE IS AN ISSUE ON THE ACCELERATION. I PRESS GAS I CAN HEAR THE NOISE ON ENGINE AS IF I WAS PRESSING GAS AND THE CAR IS ON PARK. IT HAPPENED AGAIN RIGHT BEFORE THE FIRST MAINTENANCE. THEY ASSURED ME THEY CHECKED IT AND EVERYTHING WAS FINE. I WAS RECENTLY ON THE HIGHWAY I WAS DRIVING BUT I HAD TO SLOW DOWN DUE TO TRAFFIC. WHEN SPEED PICKED UP I TRIED TO PICK UP SPEED AND AGAIN HIT THE GAS PEDDLE AND THE CAR WAS'NT MOVING

I BOUGHT THE CAR ABOUT A MONTH AGO. AND TODAY I EXPERIENCED THE CAR WHILE DRIVING AT 55MPH WHEN I WENT TO ACCELERATE TO GO THE SPEED LIMIT OF 65 ON THE MAJOR HIGHWAY GOING INTO SALISBURY, MD THAT THE CAR WOULDNT SPEED UP. AND ABOUT 30 SECONDS LATER THE TRANSMISSION SEEMED TO HAVE DOWN SHIFTED A COUPLE GEARS DUE TO THE RPMS GOING FROM 4600ISH RPM DOWN TO 2000 RPMS AND THAN THE CAR WENT BACK TO NORMAL. WHEN I HAD GOTTEN INTO SALISBURY AND HAD TO STOP IT BRAKED JUST FINE BUT WHEN I STARTED TO DRIVE AGAIN IT START TO FEEL LIKE IT WAS STALLING AND IT'S BEEN DOING IT NOW FOR THE WHOLE DAY. AS WELL AS A BURNING SMELL WHICH I'M 99% CERTAIN IS THE CLUTCH. I HAVE WORKED THE AUTOMOTIVE FIELD FOR ABOUT 7 YEARS. I HAVE A DCT TRANSMISSIONS 2018 HYUNDAI ELANTRA SPORT TECH PACKAGE. I WENT IN THE FORUM ON FACEBOOK AND SOME ELSE HAS POSTED THE SAME ISSUES. AND MANY OTHER COMMENTS. I WILL BE TAKING MINE TO THE DEALERSHIP AFTER CHRISTMAS IS OVER. BUT I'LL LIST SCREENSHOTS BELOW

TIRE PRESSURE SENSORS AND/OR TPMS MODULE PROBLEM. I PURCHASED THIS 2018 HYUNDAI ELANTRA FROM SAN TAN HYUNDAI, GILBERT, AZ 86297 IN LATE MARCH 2018. THE TIRE PRESSURE IN EACH OF THE 4 TIRES WAS 36 PSI, THE COLD TIRE PRESSURE FOR THIS AUTO.IN THE FIRST WEEK OF AUGUST 2018 THE TIRE PRESSURE WARNING LIGHT ON THE DASHBOARD CAME ON . I CHECKED THE THE TIRE PRESSURE IN EACH OF THE 4 TIRES WITH A ANALOG AND DIGITAL TIRE PRESSURE METER AND THE PRESSURE IN EACH TIRE WAS ABOUT 32 PSI. I RE- INFLATED EACH TIRE UP TO 36 PSI (SPEC REQUIREMENT) BUT THE WARNING LIGHT STAYED ON. I NOTIFIED HYUNDAI HEADQUARTERS CUSTOMER SERVICE ABOUT THE PROBLEM AND THEY ASSIGNED A CASE NUMBER AND SUGGESTED I TAKE THE NEW AUTO WITH ONLY ABOUT 1500 MILES ON ODOMETER TO SAN TAN HYUNDAI. I HAD TO WAIT ABOUT 2 WEEKS FOR A OCT.18,2018 APPOINTMENT. THE TIRE WARNING LIGHT TURNED OFF JUST BEFORE MY APPOINTMENT, SO I CANCELED THE APPOINTMENT. ON 12-18-2018 THE TIRE WARNING LIGHT CAME ON AND STAYED ON AFTER THE 4 TIRES WERE RE-INFLATED AGAIN FROM 32 PSI UP TO 39 PSI. THERE IS SOMETHING WRONG WITH HYUNDAI'S INDIVIDUAL TIRE PRESSURE SENSOR AND/OR TPMS MODULE ON MY NEW 2018 HYUNDAI ENTRANT. WHEN EACH OF THE 4 TIRES ARE RE-INFLATED TO 36 PSI,THE DASHBOARD TIRE PRESSURE INDICATOR LIGHT SHOULD TURN OFF. I HAVE MADE ANOTHER APPOINTMENT WITH SAN TAN HYUNDAI BUT WHAT I HERE FROM CUSTOMER SERVICE IS: IT MAY COST YOU DOLLARS TO FIX THIS PROBLEM INSTEAD OF INDICATING THAT IT IS COVERED UNDER MY NEW CAR WARRANTY. THIS IS WHY I AM REPORTING MY PROBLEM TO NHTSA. ON LINE REPORTS INDICATE THAT THIS MAY ALSO BE A PROBLEM WITH OTHER HYUNDAI ELANTRA VEHICLES FROM PREVIOUS YEARS.

CAR SPUTTERS AT IDLE, ACTING LIKE IT'S GOING TO CUT OFF. DOES NOT ACCELERATE PROPERLY, BUT ONLY INTERMITTENTLY. ONE DAY, THE CHECK ENGINE LIGHT CAME ON AND I COULD NOT ACCELERATE AND IT WOULD SPUTTER AT LIGHTS. DROVE IT STRAIGHT TO ADVANCE TO GET THE ENGINE LIGHT CHECKED; NOTHING CAME UP. STARTED THE CAR AGAIN AND IT DROVE FINE, LIKE NOTHING HAD HAPPENED. TOOK IT TO THE DEALERSHIP THE NEXT DAY. THEY COULDN'T DUPLICATE THE ISSUE. FINALLY, AFTER LETTING IT IDLE AWHILE, WERE ABLE TO GET A CODE ON THE COILS. REPLACED THEM ALL. CAR WAS RUNNING FINE AFTER THAT. THE SPUTTERING AT IDLE HAS NOW STARTED AGAIN.....LESS THAN 2 MONTHS LATER.
