2011 Hyundai Elantra

The Office of Defects Investigation (ODI) has received eight Hyundai Motor America (Hyundai) and eight Kia America, Inc. (Kia) Part 573 Recall Reports between 2016 and 2023. The combined 16 safety recalls all involve the antilock braking system (ABS) modules or Hydraulic Electronic Control Units (HECU) manufactured by the equipment supplier Mando. The Part 573 Recall Reports contain varying defect descriptions and differing remedy descriptions for the same or similar equipment supplied by Mando. Safety recalls included in this Audit Query (AQ) review include: Hyundai recalls 20V-520, 20V-543, 21V-161, 21V-160, 21V-303, 22V-056, 22V-810, and 23V-651. Kia recalls 16V-815, 20V-518, 20V-519, 21V-137, 21V-331, 22V-051, 22V-800, and 23V-652 The purpose of this AQ is to evaluate the timeliness and scoping of Hyundai and Kia’s defect decision making and adherence with reporting requirements; and understand the varying defect descriptions and remedies between these recalls.

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.

In March 2013, Hyundai issued a safety recall to reinforce the attachment of the metal support brackets to the headliner assembly in approximately 186,254 model year 2011-2013 Hyundai Elantra vehicles built in Korea and sold in the U.S. (see NHTSA recall 13V-115 for more information).The recall covers vehicles built up to March 5, 2013.After that date, Hyundai began using headliners with reinforced bracket attachments in the Korea-built Elantra vehicles.ODI has opened a Recall Query (RQ13-004) to investigate model year 2009-2012 Hyundai Elantra Touring vehicles.During EA12-008, ODI found these vehicles are equipped with a support bracket design and layout similar to that in the above-mentioned Elantra vehicles.Also, the headliner manufacturing processes used were similar for both models.Like the Elantra vehicles built before the recall, the Elantra Touring model headliner does not contain reinforced bracket attachments.This Engineering Analysis is closed.See attached report for additional information.The ODI report cited above can be reviewed online at http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification number: 10457696

My steering wheel began to make clanking sound and lost the tension that allows for smooth turning of the wheel for both left and right. I looked it up and have found that this is a known issue that Hyundai has not addressed. Hyundai had a batch of bad steering wheel couplers that were installed in numerous models. This steering issue could cause someone to over compensate when turning the steering wheel. Since it does not have tension, it feels like the steering is disconnected from the car. I did have a quote from Hyundai. It was between $400-$600 depending on how long it took. My car is available for inspection at any time by the manufacturer, police, insurance or other. There are no warning lights or symptoms of the problem. You are litterally driving down the road and you go to make a left or right turn and it feels like a rubber band just busted and steering becomes unpredictable.

I have a Piston/Engine Defect according to the mechanic at the car shop. Any time any acceleration is applied you can hear the knocking. I believe it should be covered through the class action alleged that 2011-2016 Elantras engines (including the Limited trim) have a piston defect leading to engine failure. A settlement offered extended warranties, engine repairs, and reimbursement. I was unaware and have already spent tons of money towards repairs to the engine over the years. Now I am aware of this lawsuit and would like some kind replacement.

The brake lines in our 2011 Hyundai Elantra have rusted out and no longer hold brake fluid, which means the car is not safe to drive. Luckily we were able to get the car to our sidewalk and park it without injury. We found that Sauder Schelkopf is investigating a potential class action lawsuit against Hyundai for underbody corrosion and brake line failure in 2011-2016 Hyundai Elantra vehicles. It has been alleged that the underbody coating of these vehicles suffer from premature wear and failure, allowing the underbody to prematurely corrode. It has been further alleged that the failure of the underbody coating on these Hyundai vehicles can cause brake line failure and the failure of other essential components resulting in serious safety issues. Hyundai has a recall out to provide underbody coating free to customers but no mention of brake line replacement.

Vehicle: 2011 Hyundai Elantra Touring Date of Crash: [XXX] Location of Crash: Duluth, MN Description of Incident: I was driving my 2011 Hyundai Elantra Touring straight through an intersection when another driver ran a stop sign and T‑boned the passenger side of my vehicle. The impact was severe enough that the vehicle was totaled, with significant structural intrusion into the passenger compartment. No airbags (side torso or curtain) deployed, although the strike was a direct side impact at approximately 30+ mph. I expected at least the side curtain or side torso airbags to deploy. My insurance adjuster noted that the lack of deployment was unexpected given the severity and nature of the crash. Outcome: Vehicle declared totaled No airbags deployed No serious injuries, but a significant safety concern INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When ever I am turning my steering wheel in either direction there is a clicking noise. It started low and now the noise became loud even when I am going over bumps on the road. I went to a reputable certified shop and I am told it is my steering column bushing and I was advised that there is a recall on it but when I further investigate my car I do not see no recall. This is a problem a lot of people are having with the 2011 Hyundai Elantra .

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. (DTN), that have been identified in U.S. vehicles following prior crashes, theft, or non‑certified airbag replacements. These inflators are not approved for use, may rupture during deployment, and have caused serious injuries and fatalities. Please see attached announcement, provided by NHTSA, for more details.

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.

In response to this trend, we engineered a software upgrade that addresses the social media theft method and made it available to owners of eligible models free of charge at authorized Hyundai dealers since early 2023. In addition to the anti-theft software, we’ve developed a new zinc-reinforced ignition cylinder protector hardware upgrade that can be installed at the ignition cylinder location to provide additional protection against the social media theft method. Because your Hyundai vehicle with the VIN listed above (“Subject Vehicle”) was not factory-equipped with an engine immobilizer and was previously eligible for the software upgrade, you are now eligible until March 31, 2027 to have the ignition cylinder protector installed — if you request it — at no cost to you through an authorized Hyundai dealership.

In addition to the Anti-Theft software provided under Service Campaign 993 (TSB 24-01-009H-1), a zinc reinforced ignition cylinder protector hardware upgrade is being made available to customers upon request. This supplemental security measure is to be installed at the ignition switch location and provides additional protection against the social media theft method. Vehicles not equipped with an immobilizer during production at the factory are eligible. The repair procedure shall be performed and claimed upon customer request only. Any future repairs to these vehicles in which an installed ignition cylinder protector impacts required parts and/or labor, shall be covered by HMA. Please see TSB 25-01-089H for details.

This bulletin provides the service procedure for installation of a key cylinder reinforcement protector assembly and two anti-theft decals on the front windows.

Upon customer's request ONLY, the Technical Service Bulletin (TSB) 25-01-089H provides the service procedure for installation of a key cylinder reinforcement protector assembly and two anti-theft decals on the front windows. This repair procedure is being provided in addition to the previous Anti-Theft software provided under Service Campaign 993 (TSB 24-01-009H-1).
