Hyundai Motor America (Hyundai) is recalling certain 2007-2010 Elantra and 2009-2011 Elantra Touring vehicles. On February 21, 2020 Hyundai expanded the recall to include 46,425 model year 2007-2008 Entourage and 2007 Santa Fe vehicles. Moisture may enter the Anti-lock Brake (ABS) Module and result in an electrical short.
Consequence & remedy
Consequence: An electrical short within the ABS Module may cause an engine compartment fire, even when the car is turned off, increasing the risk of an injury.
Remedy: Hyundai will notify owners, and dealers will install a relay in the vehicle's main junction box to prevent the risk of an ABS short-circuit while the car is turned off, free of charge. The recall began April 2, 2020. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 188.
Hyundai Motor America (Hyundai) is recalling certain model year 2008-2010 Elantra vehicles manufactured June 1, 2008, to April 30, 2010, and 2009-2010 Elantra Touring vehicles manufactured November 1, 2008, to April 30, 2010. The electronic power steering (EPS) electronic control unit (ECU) may sense a discrepancy in the steering input signals and, as a result, disable the steering power assist.
Consequence & remedy
Consequence: If power steering assist is lost, greater driver effort would be required to steer the vehicle at low speeds, increasing the risk of a crash.
Remedy: Hyundai will verify the proper operation of the Electronic Power Steering (EPS) and update the EPS control unit, free of charge. The recall began April 14, 2015. Owners may contact Hyundai customer service at 1-855-671-3059. Hyundai's number for this recall is 127.
Hyundai Motor Company (Hyundai) is recalling certain model year 2006-2009 Accent, model year 2007-2011 Azera, Sonata and Sante Fe,2006-2011 Tucson, 2009-2011 Elantra Touring, 2007-2010 Elantra, 2008-2011 Veracruz, 2009-2011 Genesis, 2010-2011 Genesis Coupe, 2007-2008 Entourage, and 2006-2008 Tiburon vehicles. Originally, in April 2013, Hyundai recalled 1,059,824 model year 2007-2009 Accent and Tucson, model year 2007-2010 Elantra, model year 2007-2011 Santa Fe, model year 2008-2009 Veracruz, model year 2010-2011 Genesis Coupe, and model year 2011 Sonata vehicles. In September 2013, Hyundai informed the agency that it was adding more vehicles to this campaign, representing an additional 652,512 units. The total number of vehicles being recalled is now 1,712,336. In the affected vehicles, the stop lamp switch may malfunction. A malfunctioning stop lamp switch may cause the brake lights to not illuminate when the brake pedal is depressed or may cause an inability to deactivate the cruise control by depressing the brake pedal. Additionally, a malfunctioning stop lamp switch may also result in intermittent operation of the push-button start feature, affect the operation of the brake transmission shift interlock feature, preventing the shifter from being moved out of the PARK position and cause the Electronic Stability Control (ESC) malfunction light to illuminate.
Consequence & remedy
Consequence: Failure to illuminate the stop lamps during braking or inability to disengage the cruise control could increase the risk of a crash. Additionally, when the ignition is in the 'ON' position, the transmission shifter may be able to be moved out of Park without first applying the brake. This may lead to unintentional movement of the car which may increase the risk of a crash.
Remedy: Hyundai will notify owners, and dealers will replace the stop lamp switch, free of charge. The safety recall began on April 22, 2013. Owners may contact Hyundai at 1-800-633-5151. Hyundai's recall campaign number is 110.
HYUNDAI IS RECALLING CERTAIN MODEL YEAR 2007-2009 ELANTRA VEHICLES MANUFACTURED FROM JULY 14, 2006, THROUGH NOVEMBER 1, 2008. THE FRONT PASSENGER SEATS IN THE VEHICLES CONTAIN A WEIGHT SENSOR DESIGNED TO DEACTIVATE THE RIGHT FRONTAL AIRBAG WHEN OCCUPANTS OF CERTAIN WEIGHTS OCCUPY THE SEAT. THE ELECTRICAL CONNECTOR FOR THE WEIGHT SENSOR IS LOCATED UNDER THE CENTER CONSOLE, BETWEEN THE FRONT SEATS. UNDER CERTAIN CIRCUMSTANCES THE CONNECTOR COULD BECOME CONTAMINATED AND MALFUNCTION SUCH THAT THE FRONT PASSENGER AIRBAG WILL DEPLOY REGARDLESS OF THE WEIGHT OF THE OCCUPANT.
Consequence & remedy
Consequence: THE FRONT PASSENGER AIR BAG COULD DEPLOY IN CRASHES IN WHICH IT SHOULD NOT DEPLOY, INCREASING THE RISK OF INJURY TO THE SEAT OCCUPANT FROM THE DEPLOYED AIR BAG.
Remedy: DEALERS WILL INSTALL A PROTECTIVE COVER OVER THE WEIGHT CLASSIFICATION SYSTEM CONNECTOR TO PREVENT CONTAMINATION. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL IS EXPECTING TO BEGIN DURING APRIL 2011. OWNERS MAY CONTACT HYUNDAI'S CUSTOMER ASSISTANCE CENTER AT 1-800-633-5151.
HYUNDAI IS RECALLING CERTAIN MODEL YEAR 2007-2008 ELANTRA VEHICLES MANUFACTURED FROM JULY 14, 2006, THROUGH AUGUST 29, 2007. THE DRIVER'S SEAT TRACK POSITION SENSOR DETERMINES THE SEAT'S FORE AND AFT POSITION AND ALLOWS THE DRIVER'S FRONTAL AIR BAG TO DEPLOY AT THE PRESSURE APPROPRIATE FOR THAT SEATING POSITION, WITH A LOWER PRESSURE DEPLOYMENT IN THE MOST FORWARD SEATING POSITIONS. THE AIR BAG CONTROL MODULE MAY RECEIVE AN UNSTABLE ELECTRICAL SIGNAL FROM THE SEAT TRACK POSITION SENSOR SUCH THAT, IN A CRASH THAT REQUIRES DRIVER FRONTAL AIRBAG DEPLOYMENT, THE DRIVER'S AIRBAG MAY DEPLOY AT THE HIGHER PRESSURE THAN INTENDED IF THE SEAT WAS POSITION IN ONE OF THE FORWARD POSITIONS IN WHICH A LOWER PRESSURE DEPLOYMENT IS INTENDED.
Consequence & remedy
Consequence: A HIGHER PRESSURE DEPLOYMENT THAN INTENDED INCREASES THE RISK OF INJURY RESULTING FROM AIRBAG DEPLOYMENT.
Remedy: DEALERS WILL REPROGRAM THE AIR BAG CONTROL MODULE FREE OF CHARGE. THE SAFETY RECALL IS EXPECTING TO BEGIN DURING APRIL 2011. OWNERS MAY CONTACT HYUNDAI'S CUSTOMER ASSISTANCE CENTER AT 1-800-633-5151.
HYUNDAI DE PUERTO RICO (HPR) IS RECALLING 347 MY 2008 ELANTRA VEHICLES. THE FUEL PUMP MOTOR MAY NOT HAVE THE PROPER, UNIFORM INTERNAL ELECTRICAL SURFACE CONTACT. THIS MAY CAUSE THE FUEL PUMP TO PRODUCE LESS PUMPING PRESSURE THAN REQUIRED TO SUPPLY THE FUEL INJECTION SYSTEM.
Consequence & remedy
Consequence: AS A RESULT, POOR ENGINE STARING AND HESITATION MAY RESULT. OTHER ENGINE PERFORMANCE ISSUES MAY ALSO RESULT AND LEAD TO A CRASH.
Remedy: DEALERS WILL REPLACE THE VEHICLE'S FUEL PUMP SUBASSEMBLY. THE RECALL BEGAN ON FEBRUARY 9, 2009. OWNERS MAY CONTACT HPR AT 1-800-981-0188.
HYUNDAI IS RECALLING 65,000 MY 2008 ELANTRA VEHICLES WITH 2.0 LITER BETA ENGINES. THE FUEL PUMP MOTOR MAY NOT HAVE THE PROPER UNIFORM INTERNAL ELECTRICAL SURFACE CONTACT. THIS MAY CAUSE THE FUEL PUMP TO PRODUCE LESS PUMPING PRESSURE THAN REQUIRED TO SUPPLY THE FUEL INJECTION SYSTEM.

Status: closed (inferred from source dates) · Vehicle Speed Control:throttle
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.
ON AUGUST 19, 2008, HYUNDAI SUBMITTED A DEFECT INFORMATION REPORT TO NHTSA CONCERNING FUEL PUMP FAILURE RESULTING IN ENGINE STALL IN APPROXIMATELY 65,000 MODEL YEAR 2008 HYUNDAI ELANTRA VEHICLES WITH 2.0 LITER BETA ENGINES PRODUCED FROM NOVEMBER 5, 2007, THROUGH JUNE 28, 2008 (NHTSA RECALL NO. 08V-429, HYUNDAI CAMPAIGN 086).THE RECALLED VEHICLES ARE EQUIPPED WITH FUEL PUMPS MANUFACTURED WITH UPPER BODY COMPONENTS FROM A DIFFERENT SUPPLIER THAN THOSE MANUFACTURED PRIOR TO NOVEMBER 5, 2007.ACCORDING TO HYUNDAI, THE NEW SUPPLIER'S UPPER BODY COMPONENTS HAD INCORRECT DIMENSIONAL CHARACTERISTICS RESULTING IN MISALIGNMENT OF THE ARMATURE SHAFT, WHICH CAUSED SOME OF THE FUEL PUMPS TO EXPERIENCE POOR BRUSH-TO-COMMENTATOR CONTACT CONDITIONS THAT COULD RESULT IN ENGINE STALL. THE USE OF ETHANOL BLEND FUEL, CONTAINING UP TO 10 PERCENT ETHANOL, CAUSES A FILM BUILD-UP THAT CREATES HIGH RESISTANCE BETWEEN THE BRUSH AND COMMUTATOR.THE MISALIGNED ARMATURE SHAFT PREVENTS THE BRUSH AND COMMUTATOR FROM MAKING SUFFICIENT CONTACT TO OVERCOME THE HIGH RESISTANCE FILM BUILD-UP, THEREFORE PRODUCING LESS PUMPING PRESSURE THAN REQUIRED TO SUPPLY THE FUEL INJECTION SYSTEM. SIXTY-FOUR OF THE COMPLAINTS (72%), INCLUDING THE CRASH AND INJURY ALLEGATION, INVOLVE THE RECALLED VEHICLES.THE COMPLAINT RATE IN THE SUBJECT VEHICLE POPULATION IS 98.5 PER 100,000 VEHICLES, COMPARED WITH 21.4 IN THE REMAINING POPULATION, WHICH HAS ON AVERAGE BEEN IN SERVICE OVER A YEAR LONGER.THE WARRANTY CLAIM RATE IS ALSO SIGNIFICANTLY HIGHER IN THE RECALLED VEHICLES, WHICH HAD 569 CLAIMS (0.9 PERCENT CLAIM RATE) COMPARED WITH 126 CLAIMS IN THE REMAINING POPULATION (0.1 PERCENT CLAIM RATE). HYUNDAI WILL REPLACE THE FUEL PUMP SUBASSEMBLIES IN THE RECALLED VEHICLES FREE OF CHARGE.THIS PRELIMINARY EVALUATION IS CLOSED WITH HYUNDAI'S RECALL.
