2008 Elantra should be added to the crankshaft Theta II recall. 2098 Elantra has the 2.0L engine unlike its prior years where they are made with a 1.6L engine. Last week my 2008 Elantra exhibited all the signs of this malfunction (A knocking noise from the engine that increases in frequency as the engine rpm increases. Reduced power and/or hesitation and vibration. Illumination of the “check engine” light in the instrument cluster. Illumination of the “engine oil pressure” warning lamp.) When this occured i had taken it to Auto Zone and had the computer scanned for error codes. (See attached report). Based on the report a tune up was done, ignition coil replaced and sensor replaced. Car would still not start. When my mechanic furthe diagnosed it (he could not find the issue until he used his scope camera)he found the issue was that there is damage to the "trigger wheel" inside the crank shaft. He also said this almost never happens in a car and does not know what could have made this happen. Please investigate this issue further, this is a dangerous situation of engine seizing and should be investigated immediately and thoroughly.

THE VEHICLE WILL ROLL AWAY WHEN PLACED IN PARK (WHILE STATIONARY) IF ATTEMPTING TO PARK ON ANY SLIGHT INCLINE OR DECLINE. A RATCHETING SOUND IS HEARD COMING FROM THE TRANSMISSION WHEN THIS OCCURS AS THE VEHICLE IS ROLLING OUT OF CONTROL. SOMETIMES IT STARTS TO ROLL AFTER YOU HAVE EXITED THE VEHICLE. THE VEHICLE EXPERIENCED THE SAME CONCERN SEVERAL YEARS AGO AND THE TRANSMISSION WAS REPLACED WITH A GOOD USED TRANSMISSION. NOW THE USED TRANSMISSION IS EXPERIENCING THE SAME ISSUE WITH NOT STAYING IN PARK. A PEDESTRIAN WAS NEARLY STRUCK LAST WEEK BY THE VEHICLE ROLLING AWAY BUT I WAS ABLE TO GET BACK IN IT AND STOP IT WITH THE SERVICE BRAKE. I HAVE READ ONLINE THAT THIS IS A COMMON OCCURRENCE WITH THE HYUNDAI ELANTRA AUTOMATIC TRANSMISSIONS.

ENTERING A CROWDED PARKING LOT IN THE CITY OF CHICAGO, I SLOWED DOWN TO APPROX. 2 MPH (ALMOST IDLE SPEED) AS I APPROACHED THE TICKET DISPENSER WHEN ALL OF A SUDDEN THE CAR ACCELERATED OVER 6000 RPMS AND TOOK OFF. AS REFLEX, I SLAMMED THE BRAKES (SINCE THE ABS DOESN'T WORK WITHOUT POWER) BUT THE ACCELERATION KEPT INCREASING AND THE BRAKES WERE NOT INHIBITING MOVEMENT SO I THEN FORCED THE KEY OUT OF THE IGNITION AND PULLED THE EMERGENCY BREAK - ALL WITHIN A SECOND OR TWO. THE CAR STOPPED WITHIN INCHES OF HITTING A FEW OTHER CARS AND PEOPLE INSIDE THOSE CARS AFTER THE FORWARD MOMENTUM HAD BEEN OVERCOMPENSATED BY THE INITIAL BRAKE PUSH AND EMERGENCY BRAKING. THERE WAS A STRONG BURNT RUBBER AND OIL SMELL BUT IT WASN'T FROM THE TIRES. THE CHECK ENGINE LIGHT CAME ON AFTER TWO DRIVING CYCLES AND HAS REMAINED ON. THIS IS A VERY SERIOUS SITUATION THAT NEEDS ATTENTION! I AM VERY EXPERIENCED DRIVER AND KNEW WHAT TO DO AND HOW TO DO IT BUT WAS STILL WITHIN INCHES OF SERIOUSLY HURTING OTHERS AND DESTROYING PROPERTY. I ALSO SUFFERED WHIPLASH ON MY NECK AND HIT THE STEERING COLUMN AS A RESULT OF THE SUDDEN STOP. AIR BAGS WERE NOT DEPLOYED. THERE ARE SEVERAL INCIDENTS THAT HAVE BEEN REPORTED IN THE PAST FEW MONTHS (MARCH 2013 - MAY 2013) BY DRIVERS IN SEVERAL STATES ON THIS SAME YEAR MODEL. I AM URGING NHTSA TO LOOK INTO THIS. I WILL ALSO CONTACT HYUNDAI AND IF HYUNDAI DOESN'T RESPOND I WILL BE CONTACTING MEDIA OUTLETS BECAUSE HYUNDAI OWNERS NEED TO BE INFORMED OF THIS VERY DANGEROUS AND POTENTIALLY FATAL SITUATION. *TR

Official recalls
7Feb 4, 2020
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.
Feb 23, 2015
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.
Apr 1, 2013
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.
Mar 15, 2011
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.

Opened Nov 12, 2021 · Closed Jun 20, 2023
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.
