On 5/30/23 while in traffic I pressed the brake to slow down and the car kept moving forward. I pressed the brake all the way down and I was still unable to stop the car from accelerating. I rear-ended the vehicle in front of me. My car is currently being inspected by a mechanic that my insurance company recommended.

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 first thing I noticed was the engine was dying when I came to a stop at a red light, with the engine idling, the car in drive and my foot on the brake. I started to put the car in neutral when I had to come to a stop, so the engine wouldn't sputter, and then back in drive when I wanted to go. After about a day or 2, the engine started revving when I put it in drive or reverse, and the brake wasn't strong enough to stop the car. I took it to my hyundai dealer, who said it needed a new transmission (specifically torque converter). I took it to a transmission shop, which rebuilt the transmission. But the car was still revving when it was put in drive and idling, with the brake on. The transmission shop researched the problem, which took about a month, and found that the control module had malfunctioned. According to the mechanic, it was sending the signal to rev the engine and cut the power to the brakes when the car was idling in gear. He said he found that there were several complaints about this make/model/year range, but there was no recall because no serious injuries or deaths had occurred because of it yet. Obviously, it is just a matter of time till this happens, when a vehicle revs its engine and cuts power to the brakes simultaneously. Once the problem was identified, the transmission shop was able to order the software from hyundai to reprogram the ECM, which solved the problem.
The speed sensor telling me speed doesn't work saying I'm going 0 the car it's self will not go out of park into drive can't drive the vechile, the ABS light keeps coming on the ctrl light keeps coming and doesn't come off the air bag light doesn't shut off check engine light came on and car almost drove me off the road and into windshield all in 2 days and before that was fine it's always has been taken care off and manage and unknown problems happened all at once where I haven't been able to drive it for 2 months
The brakes on my 2006 hyundai sonata failed on me as I was driving. My car seemed to have not been working properly.
The cruise control comes on by itself during normal driving. After the "cruise" light comes on the "set" light illuminates and the vehicle accelerates without warning. The brake will momentarily stop the acceleration, but the acceleration resumes once the brake pedal is released. It occurs above 25 MPH. It kept accelerating and would have continued if I hadn't hit the brakes. I happens regularly, and we have parked the vehicle.
Throttle body has failed 3 times in a row.
Sudden unexpected acceleration with no power brake. Acceleration of vehicle on it's own. When in park and neutral vehicle idles fine and power brakes work. With foot on brake and placing the vehicle in drive or reverse it accelerated immediately to uncontrollable speeds with no foot on the gas pedal. At the same time you lose power brake and it is impossible to control unless the driver puts the vehicle in neutral, then power brake engages and acceleration stops. This happened to my daughter's car on 4/24/18. Thankfully there was no accident. I also tested the car and it is uncontrollable. Experienced no problems or warnings prior to this. No check engine light before or after this incident. I had the car towed to my auto repair shop. Got the car on the lift and put it in drive. It immediately accelerated on it's own and reached 80 miles per hour quickly. No foot on the accelerator or brake. Decided to call hyundai dealership. The car was towed to the dealership on 4/30. The tech confirmed our concerns. On 5/11 the service manager contacted hyundai corporation on our behalf. We also called hyundai customer care on 5/13. No vehicle should extremely accelerate and lose power brake at the same time! This is a safety defect. Regardless of what the problem is no vehicle should react like this. The vehicle is still at the hyundai dealership and needs to be investigated to find the root problem and solve it! This is necessary to prevent any vehicle from doing this again. Lives are at risk and a recall needs to be done. Drive by wire system...
I was at a complete stop at a red light, with my foot securely on the brake, when my car engine revved, accelerated on it's own, and then lunged into the car in front of me. There were no injuries or damages but I am anxious and nervous about this safety issue happening again without warning.
