I was driving the car at 25 MPH, when suddenly there was a clicking noise and the car lost power. I made it to my local service shop, but they were already closed. The next morning they called to inform me that the engine had blown and that it was a common problem for Hyundai vehicles. When the engine blew, it enabled gasoline to leak into the engine compartment. I feel that this is a serious fire hazard. Even though the care had high mileage, it was in good mechanical shape at the time of the incident. I had routine maintenance performed regularly. There were never any warning indicators that something might be wrong.

This cars engine has seized and stopped working. This is an unacceptable problem and it seems as though other years have a recall for this same issue. I would like my year and model added to the recall. I am furious about this situation.

I lost power while driving my 2016 Hyundai Elantra gt and also started hearing a knocking sound so I pulled over and knocking sound got real loud. A friend came and towed me home about 70 miles and the next morning I checked the oil and my oil was empty. My car has been out of commission for over a month and my mechanic says that a ball bearing is the reason for my engine failure and knocking sound.

I WAS DRIVING TO NORWOOD ON A RESIDENTIAL ROAD AND THE CAR BEGAN OVERHEATING SO I PULLED OVER, LET IT COOL DOWN, AND ADDED WATER TO THE RADIATOR. I DIDN'T KNOW WHY IT WOULD OVERHEAT, BUT ONCE IT COOLED, I DROVE BACK HOME. WE CHECKED THE OIL AND OTHER FLUIDS TO BE SURE IT WASN'T LOW. THE FLUIDS WERE FINE AND WE THOUGHT IT WAS GOING TO BE THE RADIATOR. THE NEXT DAY, I WENT TO A LOCAL RESTAURANT IN EASTGATE OHIO. WHEN I PULLED INTO THE DRIVE THRU, IT FELT LIKE THE CAR WASN'T GETTING POWER AND THEN SHUT OFF. I WENT TO START IT, BUT IT WOULDN'T START. THE ENGINE WOULDN'T EVEN TURN OVER. I HAD TO HAVE IT TOWED BACK TO MY APARTMENT BY OUR MECHANIC. THE MECHANIC LOOKED UNDER THE HOOD AND EXPLAINED THAT THE ENGINE IS LOCKED UP. I STILL OWE ON THE VEHICLE SO I PARKED IT AND HAVE BEEN TRYING TO SAVE MONEY TO GET AN ENGINE.

NHTSA investigations
1DP21003 · Throttle Control System Vulnerabilities
Opened Nov 12, 2021 · Closed Jun 20, 2023
Status: closed (inferred from source dates) · Vehicle Speed Control:throttle
The Office of Defects Investigation (ODI) of the National Highway Traffic Safety Administration (NHTSA) received a petition letter dated October 10, 2021, requesting an investigation of possible defects in the electronic throttle control (ETC) system on certain Kia vehicles resulting in the opening of DP21-003. Accordingly, Model Year (MY) 2005-2016 Kia Optima/K5, MY 2006-2015 Kia Sorento, MY 2007-2016 Hyundai Elantra, MY 2007-2016 Hyundai Santa Fe, MY 2006-2015 Hyundai Sonatas are all part of the subject population. The petition was originally filed as a Vehicle Owner Questionnaire that can be reviewed at NHTSA.gov under reference (ODI) number 11439675.On November 12, 2021, ODI opened Defect Petition DP21-003 to evaluate the petitioner?s request. ODI performed trend analyses of the VOQs related to vehicle speed control issues for all the subject vehicles and found that none of the 52 Model/Model Year Hyundai/Kia vehicles demonstrated any actionable trend that warranted an investigation.Petitioners submitted 1119 VOQs and non-VOQ cases in which sudden uncommanded acceleration (SUA) or loss of motive power (LOMP) incidents were alleged.For the 1119 reports, 220 were incidents involving crashes, from which 69 subject Hyundai-Kia vehicles were inspected by Hyundai/Kia dealer technicians, Hyundai/Kia engineers, and/or third-party representatives.ODI found the inspections identified no vehicle defects related to the ETC system.Of the 220 crash-involved reports, 13 Event Data Recorder (EDR) records were downloaded successfully and 11 of those indicated driver error: (i.e.) pedal misapplication.A condition where the accelerator pedal is mistakenly applied instead of the brake pedal when the driver wants to stop the vehicle.In addition, ODI reviewed a scientific journal paper published in Forensic Science International in 2016 by Mr. Park et al ., as well as related test videos. ODI does not believe there is any evidence of uncontrollable SUA occurrences in any of the tests reviewed. NHTSA's Office of Vehicle Safety Compliance (OVSC) reviewed the allegations regarding the potential noncompliance with Federal Motor Vehicle Safety Standard No. 124.Based on the information provided, the Agency concludes there is insufficient information for us to determine if a possible non-compliance exists.Finally, both Hyundai and Kia informed ODI that all their vehicles manufactured after 2012 were equipped with an ETC management system, in which the engine speed will go to idle when the system sees signals from both the brake pedal and accelerator pedal at the same time; this is commonly known as the brake-throttle override system.After thoroughly assessing the material submitted by the petitioner, information already in NHTSA's possession, information submitted by Hyundai and Kia in response to an Information Request letter, and the potential risks to safety implicated by the petitioner's allegation, NHTSA does not believe that a formal investigation is warranted. After full consideration of appropriate factors, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA?s reasons for denial of the petition will be published.
