Throttle control system vulnerabilities
The Office of Defects Investigation (ODI) of the federal safety agency 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 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. the federal safety agency'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 the federal safety agency'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, the federal safety agency 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 the federal safety agency?s reasons for denial of the petition will be published.

The car shut off on me while driving
The ESC kight keeps turning on . The brake lights wont turn off, it wont let me accelerate while im driving at different speeds or it will decelerate abruptly. Yes its available for inspection. My safety and the safety of my two young children were at risk multiple times. This is my daily driver. And i was driving them to school when the car would not let me accelerate and someone almost hit me from the back. Also it happened to us on the freeway a few times as we are driving 65 mph the car decelerates abruptly almost causing major accidents while my children are in the vehicle with me. Not yet , i called the nearest kia dealer and they didnt have appointment ls until july - august. There were no warning lights at all. At first we didnt know what was the problem. After the few times it happened then the ESC light turned on and it stays on. Also the brake light wont turn off even when the car is off.
The contact owned a 2013 Kia Optima. The contact stated while her son was driving approximately 35-40 MPH, the check engine warning light illuminated and was flashing; however, he continued driving the vehicle. The contact stated that she later took the vehicle to an independent mechanic, where it was diagnosed that the knock sensor and an unknown component needed to be replaced. The vehicle was repaired; however, 6 hours later while her son was driving 65 MPH, the vehicle stalled. The vehicle was unable to restart and was towed back to the independent mechanic. The independent mechanic then informed the contact that the engine needed to be replaced. The vehicle was then towed to the local dealer who confirmed that the engine needed to be replaced. The engine was replaced by the local dealer approximately in October of 2021. The contact then stated that on March 13, 2023, while her son was driving at an unknown speed, the vehicle crossed the center line and crashed into a tree on the other side of the road. The contact stated that the air bags deployed; however, her son was pronounced deceased at the scene. A Police report was filed. The contact stated that the Police Officer informed her that the speedometer was reading 90 MPH at the time of the crash and that the Event Data Recorder (EDR) was destroyed. The contact stated that the engine and transmission dislodged from the vehicle approximately 30-feet. The contact was concerned that the crash might have been caused by unintended acceleration. The vehicle was towed to a tow yard. The cause of the failure was not yet determined. The manufacturer had not been informed of the failure. The failure mileage was approximately 114,000.
After accelerating from a stop and releasing my foot from the gas petal the car will start to accelerate on its own and speed up.
I purchased my vechile Dec 28 2021, after driving it exactly one month, as I was driving on the high way my vechile shut off it was the scariest thing that has happened to me the car couldn't brake turn on nor accelerate I had to pull over on the break from being in the middle lane i had to be cautious due to vechile passing fast. Once the car stopped. Had to pay for towing due a state police showing up regardless if I had it on my insurance. I lost my good paying job due to this due to working 45 min away. I had my recall appointment for March 10th already scheduled before hand and my car was parked for a Lil over a month then towed to the dealer. It's been 2 months and yet no vechile nor a temp vechile provided from the dealer told me there's nothing they can do. I called 3 days ago and they keep telling me nothing has been done yet anther month my vechile has to be there. It's crazy that the repairs has nothing to do with me nor my fault and I had to loose a 30 dollar paying job backed me up on rent car payment and everything else and still no consideration.
Traction control is too sensative. I was in a stop sign. Then tried to press the acceleration but vehicle lost power. Too sensative traction control caused me to stall in the middle. There were car coming from the left or right to me. I am glad I was at safe distance and could regain control of the car.
My 2013 kia optima suddenly lost power when pulling out onto the highway. When diagnosed it says turbo boost position sensor circuit
I left work one night and started fine and was driving normal for about 10-15 miles then every single light came on the dash board then couldn't accelerate anymore! It dropped in like 15mph increments until it finally rolled to a stop! I cut the car off and ever since it cut off it hasn't cut back on since me and cousin looked and seen no obvious problems but think the motor locked up completely!
When I was driving all the lights came on on the dashboard and I couldn't accelerate at all then it cut off and haven't been able to jump it off or anything! We've looked to see if we could find out why but it's just died and I think the motor locked up!
