The contact called on behalf of their son who owns a 2020 Hyundai Elantra. The contact stated that while their son was decelerating, speed was unknown, and coming to a stop sign. The next thing their son was able to recall was that the vehicle had suddenly turned right crashing into an electrical pole nearby. The air bags deployed. The driver had lost consciousness during the crash making it difficult to recall all that occurred. The vehicle was towed but they had not yet received any confirmation if the vehicle had been totaled. The electrical pole had fallen and began to catch fire. The fire department had put out the fire. The contact was not completely sure of the damage done to the vehicle. The driver lost consciousness and received an injury on their right arm. Medical attention was needed.

When cruise control is activated the rpm increases 700 to 1000 rpm regardless of the speed

NHTSA ODI 11484125

WHEN CRUISE CONTROL IS ACTIVATED, THE ENGINE RPM AUTOMATICALLY INCREASES BY ABOUT 700 RPM. AT 75 MPH, THE ENGINE RPM IS 2300. WHEN CONTROL IS ACTIVATED, ENGINE RPM INCREASES TO 3000 RPM AND REMAINS THERE. THIS DECREASES GAS MILESGE AND INCREASES WEAR ON ENGINE.

CONDITIONS: WHILE DRIVING ON A FLAT ROAD SURFACE/TERRAIN, MAINTAINING A CONSISTENT SPEED, AND CONSISTENT PEDAL APPLICATION. IF YOU SET CRUISE CONTROL, THE RPMS WILL JUMP BY 500 OR MORE. THE JUMP IN ENGINE SPEED IS MAINTAINED, NOT TEMPORARY. THE SUSTAINED INCREASE IN ENGINE SPEED WILL REDUCE FUEL ECONOMY AND INCREASE MECHANICAL WEAR ON THE VEHICLE. THIS ISSUE HAS BEEN PRESENT SINCE THE VEHICLE WAS PURCHASED BRAND NEW. I DO HAVE A VIDEO BUT THE 5 MB FILE SIZE LIMIT PREVENTS ME FROM UPLOADING.

WHILE DRIVING AT 60 MPH ON A HIGHWAY I ENGAGED THE CRUISE CONTROL. TO MY SURPRISE THE ENGINE SPEED INCREASED BY 500-700 RPM. THIS SEEMS TO ME TO BE A DEFECT IN THE WAY THE INTELLIGENT VARIABLE TRANSMISSION (IVT) SHOULD OPERATE OR ANY TRANSMISSION SHOULD OPERATE. THE RESULT IS THAT GAS MILEAGE WILL DECREASE AND ENGINE WEAR INCREASE AS A RESULT OF HIGHER RPM THAN NECESSARY. I BELIEVE THIS IS A DEFECT AND SHOULD RESULT IN A RECALL BY HYUNDAI TO CHANGE THE OPERATION OF THE TRANSMISSION. THERE ARE MANY COMPLAINTS ABOUT THIS ISSUE FROM OWNERS. I HAVE CONTACTED MY DEALER AND THEY, IN TURN, CONTACTED HYUNDAI. I HAVE ALSO CONTACT HYUNDAI CUSTOMER CARE. AS OF THIS WRITING I HAVE NOT RECEIVED ANY INDICATION FROM HYUNDAI THAT THIS CONDITION EXISTS AND THAT IT IS A PROBLEM. I'M HOPING YOU CAN REQUIRE A RECALL TO ADDRESS THE ISSUE.
