2009 Hyundai Elantra

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.

The contact owns a 2009 Hyundai Elantra. The contact stated that while the vehicle was parked and stationary, the vehicle was started and the steering wheel was very stiff. The contact originally thought that the issue was battery related; however, replacing the battery failed to resolve the issue. Due to the failure, the EPS and TPMS warning lights illuminated. The contact received notification of NHTSA Campaign Number: 15V100000 (Steering); however, the part to do the recall repair was not yet available. The manufacturer was made aware of the issue and stated that the part was not available. The local dealer was contacted but was unable to receive the part. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The failure mileage was 209,000.

The Anti-Lock Braking System (ABS) module has failed due to moisture intrusion that caused an internal electrical short circuit, destroying the ABS Primary Pressure Sensor. A few days after the vehicle was parked outside during heavy rain, I was driving on a busy highway when it suddenly lost engine power. During this emergency, I had to perform heavy braking and maneuver to the shoulder without engine assist. At the same time, the ABS and Electronic Stability Control (ESC) systems suddenly disabled completely. This failure is consistent with the safety defect described in NHTSA Campaign 20V-061 (Recall 188), which acknowledges that these ABS modules can permit moisture intrusion. However, Hyundai's remedy, installing a fuse relay, only cuts battery power while the vehicle is parked to reduce fire risk; it does not seal or repair the ABS module. Moisture from the heavy rain entered the module while the vehicle was parked and ultimately shorted the internal pressure sensor while driving, disabling critical braking and stability systems. Two independent third-party sources (an ASE-certified mechanic and a commercial automotive diagnostic scanner) identified codes C1237 (ABS Primary Pressure Sensor Signal), C1513, and C1260. Both confirmed an internal electrical failure of the ABS module. At Hyundai Corporate Consumer Affairs’ direction, the vehicle was inspected by an authorized Hyundai dealership. The dealership did not perform the required dynamic road test needed to reproduce the active ABS faults, and claimed there was only C1260 and not an ABS malfunction. The invoice documents identical mileage in and out, and video shows diagnostics performed while the vehicle was stationary with the engine off. Approximately 15 minutes later, an independent scanner successfully retrieved C1237, C1513, and C1260. Despite this evidence, Hyundai Consumer Affairs refused to repair the failed ABS module, characterizing it as a “maintenance item.”

I am reporting Hyundai’s failure to complete open Campaign 127/NHTSA Recall 15V-100 on my 2009 Hyundai Elantra. I acquired the vehicle from a family member in late July 2026 after the previous owner died and the vehicle was delayed in probate. I sought recall service immediately after legal transfer. Component/system: The Electronic Power Steering (EPS) failed. Power steering assist is completely unavailable. The EPS warning lamp is illuminated and the EPS module reports DTC C1604. The vehicle and EPS system remain at [XXX] Hyundai in [XXX] and are available for inspection upon request. Safety risk: The vehicle was driven from [XXX] to [XXX] during transportation during its transfer to me, and the power steering failed en route. Loss of steering assist substantially increased steering effort suddenly& created a safety risk to the driver, passengers and other motorists. Dealer confirmation: Yes. The condition is recognized by [XXX] Hyundai. I presented the vehicle on XXX specifically for the open EPS recall, and it has remained there since. This is the second area Hyundai dealer that attempted to decline recall service. [XXX] states it cannot perform the prescribed software update because the required Hyundai tablet/programming equipment is no longer available. The dealer has also pressured me to retrieve the unrepaired vehicle and attempted to charge for diagnostics. Other inspections: Hyundai Consumer Affairs is involved under case #XXX. No police or insurance representative has inspected the vehicle. Hyundai’s latest update is that it is attempting to source either the required computer or part, but no remedy or completion date has been provided. Warnings/symptoms: When the EPS failed, the EPS warning lamp illuminated and steering assist was lost. OBD-II/EPS diagnostics subsequently identified C1604. The vehicle has been continuously available for recall repair since XXX. Thank you for your review & assistance with this.

Some Hyundai vehicles may be equipped with a parking distance warning (PDW) sensor(s) that may trigger various DTCs and display warning messages on the instrument cluster, resulting in the PDW sensor(s) failing to detect nearby objects or triggering multiple false alarms. This condition may be a result of external damage to the PDW sensor membrane or sensor cover from rock chips or road debris, a collision, or previous vehicle repairs or modifications.

Some vehicles equipped with internal combustion engines may exhibit higher-than-expected engine oil consumption. This bulletin outlines the combustion chamber cleaning procedure for vehicles diagnosed with this condition. All internal combustion engines consume some engine oil during normal operation, depending on driving conditions and mileage, and this procedure should only be performed when deemed necessary based on inspection and diagnosis of the vehicle as outlined in TSB 26-EM-015H, Engine Oil Consumption – Inspection & Repair Guidelines, or the latest revision.

Certain vehicles equipped with internal combustion engines may exhibit higher-than-expected engine oil consumption. This bulletin provides the inspection and repair procedures for vehicles exhibiting this condition. All internal combustion engines consume engine oil as part of normal engine operation. Oil consumption rates may vary based on mileage, operating conditions, driving habits, and maintenance history. Hyundai recommends following the prescribed maintenance schedule and periodically checking the engine oil level using the dipstick to maintain proper engine oil level.

The National Highway Traffic Safety Administration (NHTSA) has identified the presence of substandard and dangerous driver’s-side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN). These inflators were not supplied, approved, or authorized by the vehicle manufacturers and have primarily been found in vehicles that previously experienced a crash and underwent airbag replacement using non-genuine parts. These dangerous inflators have ruptured during deployment, posing a serious risk of injury or death due to metal fragments entering the vehicle cabin. To date, Hyundai is aware of three people who have died while driving a Hyundai vehicle with one of these substandard replacement airbag inflators that deployed in what likely would have been a survivable crash. NHTSA has issued a public advisory urging vehicle owners and service professionals to have vehicles inspected if there is reason to believe that a non-genuine replacement airbag may have been installed. Vehicles with salvage or rebuilt titles, prior airbag deployments, or unknown repair histories may present a higher risk. NHTSA strongly cautions against self-inspection by vehicle owners and recommends inspection by trained technicians.

The National Highway Traffic Safety Administration (NHTSA) has issued an urgent safety advisory regarding dangerous, counterfeit driver‑side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd.
