Vehicle Information: 2014 Hyundai Elantra SE Sedan, 4-Cylinder, 6-Speed Automatic, FWD Build Location: USA-Built Version (Montgomery, AL - VIN '5NP') Ownership: Second owner, purchased Certified Pre-Owned (CPO) from the Hyundai of New Port Richey dealer (Florida) in March 2016. Vehicle is owned outright. Mileage: 128,638 Approximate Date Incident Noticed: October 1, 2025 DESCRIPTION OF CRITICAL SAFETY DEFECT & WARRANTY REJECTION I am reporting a failure of the clock spring assembly, which compromises critical safety features and poses an unreasonable risk, especially since this vehicle regularly transports passengers, including children. My VIN was rejected by the Hyundai TXXA Clock Spring Extended Warranty validator despite exhibiting the exact failures covered by the campaign. Safety Failures: Airbag (SRS): Warning light is constantly illuminated; driver-side airbag is disabled and will not deploy, endangering the driver and front passenger. Horn: Completely inoperable, eliminating a vital safety communication feature required to warn other drivers. Cruise Control: Buttons on the steering wheel are non-functional. These failures are caused by a broken electrical connection within the clock spring (which typically runs the Airbag, Horn, and Cruise Control circuits). I believe the denial is related to my vehicle being the USA-Built version (VIN '5NP'). I request that the federal safety agency investigate why this safety campaign arbitrarily excludes USA-built Elantras (but not Korean-built) experiencing the identical failure, thereby placing an unreasonable repair cost burden on owners for a critical safety component.

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.

What 2014 Hyundai Elantra owners say
Most recent owner complaints, unedited.
This has occurred three separate times, but this report explains what happened during the most recent occurrence. I was driving at 40 mph. The car in front of me hit their brakes, so I lightly tapped my brakes to slow down. When I tapped the gas pedal, the car would not increase speed. The check engine light, oil light, and battery light each turned on simultaneously. The car then stalled completely, but the lights remained on and the car didn’t lose power. I hit the brakes (which were now hard to push down), hit my emergency flashes so that the car behind me would pass me, pulled over to the side of the road, and then I turned off the car. When I turned the car back on, 30 seconds later, all of the lights were off and the car started with no issue.
My car is only at 46000 miles.SinceI'm purchase from dealer it has given me the same issues of RPMs shooting up &speedometer going out of control the car wont go past 20mph & jerks back & forth, tyrning off while driving & has had a b"bad" drive since purchase. I dont know the issue and its never been fixed by dealer even though i took it in a few times for these issues. it now foing it again. my life is in danger with this care since purchase & hyundai shouldve replaced my car or engine but they do not care. this car is a lemon. and now the car can go on fire parked or driving? what can be done..on the nextvpart of complaint im putting down ladt week sice this is the newest incident of the desc.
The piston rings do not seal leading to increased oil consumption and very low oil. My safety was put at risk because when I pulled out into traffic that was going at a high speed I could not accelerate. There was no warning or indication that this was going on prior to this incident. Yes this has been confirmed by a Hyundai dealership and the component was inspected. There was no warning sign before this incident.
I have 2014 Hyundai Elantra it unsafe to drive put in drive it wouldn’t go forward . It jerky hard to go. Failure of light. Transmission.steer clutch shaft
While driving over the last month, the car shuts off with no warning. There are no check engine or other lights that come on once it shuts down. There does not appear to be any consistency in the occurences, sometimes while idling, sometimes while driving 40 mph. Up until recently, the car would restart once I put it in neutral, but it now does not restart right away.
I was driving the vehicle normally down the highway. When I exited the highway, I came to a stop light and made a complete stop at which point the engine stalled. I restarted the vehicle, the check engine light appeared, but I couldn’t get it to register any RPMs and I was left stranded in a busy intersection until help arrived.
my car will stall randomly at stop signs and red lights with absolutely no warning. it’s super dangerous and has almost caused a wreck. i have taken it to mechanic and no codes are being thrown and it’s showing nothing is wrong. it’s a matter of time a accident happens and someone gets hurt. I would definitely like to figure this out!
