Electronic Parking Brake

The Office of Defects Investigation opened this investigation on September 3, 2016 based on four reports alleging the rear brakes locked or applied while driving without brake pedal application. One of the reports alleged a fire in the right rear wheel area.The vehicles subject to the investigation ... are equipped with an optional Electronic Parking Brake (EPB). In this system, an electric motor applies the parking brake by moving the rear brake pads (pads) against the brake rotors (rotors) when activated by the EPB control switch. The EPB is released by the control switch or by selecting a drive gear with the transmission shifter when the ignition is on.If the EPB has not been used within 1000 kilometers (621 miles) the system is designed to perform an Automatic Adjustment Function (AAF) of the pads to check for proper clearance. This function is a pad adjustment only and is preformed with the vehicle in park with the ignition off. It does not set the parking brake or turn the brake indicator light on. Hyundai has identified an error within the EPB control logic that can cause the pads to remain in contact with the rotors at various levels of force after the AAF is completed. This condition could cause the rear brakes to drag at the next drive cycle and may generate some levels of heat and smoke. The EPB control logic error affects model year 2016 vehicles produced from the start of production through March 16, 2016.Vehicles produced from March 17, 2016 incorporate an updated EPB control logic to prevent brake pad drag. On May 11, 2016 Hyundai notified its dealer network of Service Campaign TFF to update the EPB control logic in the affected vehicle population. Dealers will reflash the EPB software to prevent brake pad drag.There are no reports of accidents or injuries as a result of this issue. The incident that alleged fire could not be confirmed as there were no repairs to the vehicle other than replacement of the rear brake rotors and pads.ODI is closing this investigation based on the manufacturer's Service Campaign of the affected vehicles and in consideration that the the effect of brake drag in this instance does not appear to present an unreasonable risk to motor vehicle safety. The ODI reports cited above can be viewed at www-odi.nhtsa/complaints under the following identification (ODI)numbers: 10820359, 10854476, 10875764, 10892736, and 10928478Read more

Seat Belt Buckle Electrical Malfunction

On July 22, 2014 the Office of Defects Investigation (ODI) opened a preliminary evaluation to further analyze allegations of seat belt pretensioner malfunctions on model year (MY) 2006-2008 Hyundai Sonata vehicles.ODI received 131 unique reports alleging a failure within the seat belt pretensioner s... ystem, which was typically preceded by SRS light illumination.ODI requested more information from Hyundai in order to understand the nature of the failure and how the airbag deployment algorithm, the seat belt pretensioners, and/or the airbag function may be affected. In response to ODI?s information request (IR), Hyundai submitted 764 unique consumer and field reports and 19,847 warranty claims related to a failure in the front seat belt buckle assembly potentially causing a malfunction of the seat belt pretensioners.In it's response, Hyundai advised that if the resistance specifications for the seat belt buckle pretensioner circuit, located in the seat belt stalk, exceed the nominal range, a diagnostic trouble code will be set and the SRS warning indicator lamp will illuminate.The presence of this stored code will not affect the ability of the SRS Control Module (SRSCM) to detect a collision and command deployment of the pretensioners and airbags, if warranted.In fact, the wiring harness connector may be unplugged from the seat belt buckle pretensioner, and the signal to deploy the pretensioner will still be commanded and recorded.MY 2006-2008 Sonata?s utilize a dual pretensioner system by incorporating pretensioners into both the driver and front passenger seat belt retractor and the seat belt buckle assembly.The retractor pretensioner is located inside the B-pillar and winds (pretensions) the seat belt webbing back into the retractor housing during a collision, helping to remove seat belt slack and restrain the upper torso and hips.In contrast, the buckle pretensioner is located within the stalk of the seat belt assembly and acts to supplement lower limb protection.Both pretensioners are controlled by the SRSCM but utilize separate wiring and connectors.The seat belt retractor pretensioner circuitry and operation is independent of the seat belt buckle pretensioner connector and circuitry.Hyundai produced analysis indicating that increased resistance in the seat belt pretensioner which occurs in vehicle service does not result in a loss of buckle pretensioner.Hyundai further advised that in the unlikely event that a seat belt buckle pretensioner may not deploy due to increased resistance, the retractor pretensioner would still activate.Hyundai advised that the subject vehicles maintain their 5 STAR NHTSA safety rating using the retractor based pretensioner only.ODI notes that MY 2009-10 Sonatas reverted back to a single pretensioner system, and do not utilize seat belt buckle pretensioners. Hyundai advised its intention to initiate a warranty extension program to address concerns with the seat belt buckle prentensioner faults in MY 2006-2008 Hyundai Sonata vehicles.This action will extend the warranty coverage for this issue for 15 years or 250,000 miles, whichever occurs first.Given Hyundai's action and the minimal safety consequence this issue presents, further use of agency resources does not appear to be warranted.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The agency will monitor the issue and reserves the right to take further action if warranted by the circumstances.
