2017 Hyundai Sonata PLUG-IN Hybrid

TL* THE CONTACT OWNS A 2017 HYUNDAI SONATA PLUGIN HYBRID. THE CONTACT STATED WHILE DRIVING 50 MPH, SHE HEARD AN ABNORMAL SOUND. THE CONTACT STATED THAT THERE WAS NO WARNING LIGHT ILLUMINATED. THE CONTACT DROVE TO HER RESIDENCE. THE CONTACT STATED SHE HAD THE VEHICLE TOWED TO HARRISONBURG FORD, INC. (3155 S MAIN ST, HARRISONBURG, VA 22801; (540) 434-0700), WHERE IT WAS DIAGNOSED WITH NEEDING THE ENGINE TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER HAD NOT BEEN INFORMED OF FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 75,000.*DT

I WAS DRIVING MY HYUNDAI 2017 SONATA PLUGIN HYBRID ON THE HIGH WAY IN HEV MODE AND SUDDENLY I FELT SEVERE VIBRATION IN MY CAR. THEN I CHANGED MY ENGINE TO EV MODE AND IT WAS FINE. ENGINE LIGHT CAME ON. EVERY TIME THE GAS ENGINE CAME ON THE CAR STARTED VIBRATING AND NON RESPONSIVE TO GAS. I DROVE ABOUT 10 MORE KM TOWARDS HOME ON ELECTRIC ONLY ENGINE AND THEN GOT IT TOWED TO THE DEALERSHIP. IT FELT LIKE ENGINE LOST ITS POWER. I RECENTLY CHANGED THE VOLTAGE PROTECTION DEVICE ON THE CAR AS A RECALL. ALL SERVICES WERE DONE ON TIME AND CAR HAD ONLY 33000 KM.

THE SHARK FIN ANTENNA COVER CAME OFF THE VEHICLE. WHEN I PARKED THE CAR, AFTER DRIVING ON THE HIGHWAY, I NOTICED THAT IT WAS GONE. THIS DEFINITELY CAN POSE A DRIVING HAZARD IF IT COMES OFF THE VEHICLE WHILE DRIVING ON THE HIGHWAY. I NOTICED THAT WHAT WAS LEFT OF THE BASE MOUNTS APPEARED TO BE CRACKED WHICH RESULTED IN THE FIN BREAKING FREE. THIS DEFINITELY APPEARS TO BE A MANUFACTURING DEFECT. IT'S APPROXIMATELY A $500 COST AT THE DEALER TO REPAIR. THIS SHOULDN'T HAPPEN AFTER TWO YEARS OF CAR OWNERSHIP. IT WILL GET VERY COSTLY TO REPLACE THIS AT THE DEALER EVERY TWO YEARS. BASED ON OTHERS' EXPERIENCES, THIS APPEARS TO BE A COMMON OCCURRENCE WITH THIS VEHICLE.

WHILE VEHICLE IS IN MOTION AT VARIOUS SPEEDS WITH CRUISE CONTROL ENGAGED CLIMBING UP ON HILLY OR STEEPER GRADES THE VEHICLE ACCELERATES ON THE DASH AT NEARLY 100 PERCENT POWER ACCORDING TO THE HYBRID TACHOMETER. THIS INCREASE IN POWER SURPASSES WELL OVER THE SET CRUISE SPEED. FROM WHAT I HAVE NOTICED ITS 6-10 MPH CLIMBING PAST MY SET SPEED. THERE IS ALSO A LONG DELAY IN POWER RESTORATION AFTER COASTING DOWN HILLS. I FOUND IT TO BE EXTREMELY DANGEROUS WITH THE VEHICLE AT 100 PERCENT POWER BECAUSE IT COULD CREATE A SITUATION IN WHICH YOU COULD POSSIBLY REAREND ANOTHER DRIVER OR LOSE CONTROL IN NORMAL OR ADVERSE DRIVING CONDITIONS, RESULTING IN INJURY OR LOSS OF LIFE. IN ADDITION THE ISSUE COULD LEAD TO A TRAFFIC INFRACTION. MY STATE HAS A LOT OF SPEED CAMERAS. THIS PROBLEM HAVE RESULTED FROM THE RECENT RECALL WHERE HYUNDAI INSTALLED A NEW BATTERY MANAGEMENT SYSTEM. THE VEHICLE HAS APROXIMENTLY 16400 MILES ON IT.

THIS IS THE PLUGIN HYBRID MODEL. THE LITHIUM ION BATTERY CANNOT BE CHARGED SOMETIMES DUE TO OVERHEATING CONDITION. IF THIS IS NOT FIXED, IT MIGHT CAUSE A FIRE OR EXPLOSION. SOMETIMES, IT WILL NOT LET YOU CHARGE. IT WILL NOT EVEN LET YOU TURN OFF THE CHARGE SCHEDULE TO CHARGE. SOMETIMES, IT STOPS CHARGING DUE TO THERMAL PROBLEM. HYUNDAI IS NOT TAKING RESPONSIBILITY TO FIX THIS. ATTACHED PHOTO DOCUMENTED THAT IT DID NOT ALLOW ME TO SWITCH OFF THE CHARGE SCHEDULER TO START CHARGING. I HOPE HYUNDAI WILL ADDRESS THIS PROBLEM BEFORE THE CAR BURNS UP OR EXPLODES.

2017 HYUNDAI SONATA PLUG IN FEATURE FORWARD COLLISION WARNING ON FRONT STICKER SHOULD HAVE ALSO SAID IT ONLY WORKS ABOVE 25MPH AND IT DOES NOT ACTIVATE WARNING SOON ENOUGH SO I THINK ITS CRASH ZONE AND SHOUDL BE ADJUSTABLE AND TESTABLE IT IS NOT NTSB I HOPE CAN HELP MANUFACTURE A STANDARD TERMINOLOGY WHEN IT COME TO SALES AND RELEASE OF HYUNDAI LIABLE IN CASE FAILURE , YES I KNOW THEY WILL NOT COVER FAILURE UNDER MANY CONDITIONS, BUT THE SYSTEM I BROUGHT TO HYUNDAI 2X ONE IN JULY 2017 AND ONE IN MAR 2018 I WAS TOLD FRONTSIDE COLLISION WORK , THERE ARE NO ADJUSTMET FOR DISTANCE VS SPEED TECH JUST TAKE ME FOR RIDE ALMOST COLLIDE WITH THE CAR BEFORE THE COLLISION WARNING CAME ON IT SHOULD HAVE COME ON WITHIN 1-2 SECOND RULE, AND HYUNDAI HAS CHANGE THE SYSTEM FOR YEAR 2018 ,, I'M WORK WITH HYUNDAI TO GET PROPER LABEL , AND RETURN CAR FOR NTSB THE STICKER SHOULD BE MADE TO STATE TYPE OF SYSTEM AND HYUNDAI SHOULD ASK CONSUMER TO SIGN LIABLE RELAEASE THAT SYSTEM WONT ALWAYS WORK, HYUNDAI IS WORK WITH ME, SO THANKS, BUT NTSB SHOUD TEST FRONTSIDE COLLISION SYSTEMS RATE THEM TECHS SHOULD NOT HAVE TO DRIVE THE CAR INTO A CRASH ZONE TO TEST IT, AND I SHOULD BE TOLD SYSTEM NOT WORK<25MPH EVASIVE SALE BUT HYUNDAI WORK WITH ME FYI EXAMPLE OF GOOD SYSTEM IS MOBILEYE 630 FOR FRONTSIDE

TL* THE CONTACT OWNS A 2017 HYUNDAI SONATA HYBRID. WHILE DRIVING APPROXIMATELY 20 MPH, THE FRONT SIDE COLLISION WARNING SYSTEM FAILED TO FUNCTION. THE VEHICLE WAS TAKEN TO STEVENS CREEK HYUNDAI (4425 STEVENS CREEK BLVD, SANTA CLARA, CA 95051), BUT THE FAILURE WAS UNABLE TO BE DIAGNOSED. THE VEHICLE WAS NOT REPAIRED AND THE FAILURE RECURRED. THE MANUFACTURER WAS NOT CONTACTED. THE APPROXIMATE FAILURE MILEAGE WAS 13,000.

THIS IS MY FIRST TIME BUYING A BRAND NEW CAR IN MY MID 40'S. I PURCHASED THE CAR (PLUG IN HYBRID) WITH ONLY 25 MILES ON MARCH 15, 2018 AND AFTER 7 DAYS AND 353 MILES LATER, UPON DRIVING AND COMING TO A STOP IN THE CITY OF PHILADELPHIA, PA, THE CAR STALLED AND LOST POWER. WARNING MESSAGE "CHECK HYBRID SYSTEM." I HAD TO STEP ON THE GAS PEDAL ALL THE WAY DOWN TO THE FLOOR AND WAITED A SECOND OR TWO IN ORDER FOR IT TO MOVE AT A TURTLE'S PACE. FORTUNATELY, I WAS ABLE TO FIND A SAFE SPOT TO PARK THE CAR. IT WAS TOWED TO A LOCAL HYUNDAI DEALERSHIP NEAR ME AND AS OF YESTERDAY, 3/27, NO DIAGNOSTIC FINDINGS. I HAVE NOTIFIED HYUNDAI MOTOR AMERICA AND THEY HAVE OPENED A CASE#. I HAVE ALSO REACHED OUT TO THE SELLING DEALER TO HELP ME WITH THIS MATTER. THIS IS EXTREMELY UPSETTING AND DISAPPOINTING, ESPECIALLY FOR ME AS NEW CAR BUYER!!!

AROUND 10PM, WANTED TO TAKE A PICTURE OF ALL THE LIGHTS, SO PULLED CHARGING CABLE OUT AND STARTED CAR. ALL LIGHTS WERE OFF EXCEPT MIL! DECIDED TO TEST DRIVE AND FOUND NO LOSS OF POWER. TOOK IT TO NEARBY FREEWAY, FLOORED GAS PEDAL. CAR RESPONDED WITH FULL POWER! NEXT DAY MORNING, DRIVING CAR TO DEALER, HEV LIGHT AND CONTINUOUS WARNING BEEP CAME ON, JUST A MILE AWAY FROM HOME.
