The Hydraulic Electronic Control Unit (HECU) is part of the Anti-Lock braking system. The vehicles being recalled may have been assembled with brake fluid that does not protect the HECU from corrosion. If the module were to corrode, braking effectiveness could be reduced, increasing the risk of a crash. For vehicles manufactured prior to June 01, 2010, dealers will change the brake fluid and inspect the HECU, repairing it as necessary. For vehicles manufactured after June 01, 2010 dealers will flush the HECU assembly and brake system and change the brake fluid.
The rear suspension is the attaching point for the control arms and other rear suspension components. Road salt and water can accumulate in and around the rear crossmember causing it to rust. Excessive rust could cause one or both rear control arms to separate from the crossmember resulting in a sudden change in vehicle handling, increasing the risk of a crash. Dealers will inspect the rear crossmember and repair or replace it as necessary to correct this concern.
The front axles direct engine power to the front wheels. Vehicles equipped with a 2.4L engine are being recalled because the right front axle may break. This could result in loss of engine power to the wheels and the vehicle would no longer be able to move under it own power. Also, if the parking brake is not applied when the vehicle is parked it could roll unexpectedly. Both of these conditions increases the risk of a crash. Dealers will replace the affected axle shaft assembly to correct this concern.
The passenger airbag system on late model vehicles is designed to properly classify the type of passenger occupying the passenger seat. Possibilities include an adult, child, or child safety seat. These vehicles are being recalled because the passenger seat occupant may not be correctly classified by the airbag system. As a result the passenger airbag could deploy with a force inappropriate for the passenger seat occupant, increasing the risk of personal injury. Dealers will recalibrate the airbag system to correct this concern.
The affected vehicles are being recalled because the brake light switch can fail prematurely, resulting in the loss of brake light operation. Other systems that may be affected include: cruise control, push-button start, gear shifter, and Electronic Stability Control (ESC) system. Dealers will replace the brake light switch to correct this concern.
Hyundai found that a support bracket for the headliner could come loose when the side curtain airbags are deployed. In the event the side airbag is deployed, the bracket could come loose and cause injury to the occupants. Dealers will apply adhesive strips to the headliner to correct this concern.
During its installation at the factory, the panoramic sunroof assembly may have been weakened. As a result the sunroof glass may break unexpectedly while driving which could leak to personal injury and/or a vehicle crash. Dealers will inspect the integrity of the sunroof and replace the glass assembly as necessary to correct this concern.
The rear brakes on the 2012 Veloster contain certain components of the parking brake system. Moisture and road grime that collects on the rear brakes may cause the parking brake components to bind, and potentially fail to work properly. This is only affecting vehicles equipped with manual transmissions. If the parking brake is not fully engaged when parked, the vehicle may move unexpectedly, increasing the risk of a crash. Hyundai dealers will replace both rear brake calipers to correct this concern.
The panoramic sunroof assembly may have been weakened during its installation at the factory. As a result, the glass panel may break while driving, resulting in personal injury or a vehicle crash. Dealers will inspect the sunroof and replace the glass assembly as necessary.
Hyundai is recalling certain 2007 through 2009 Santa Fe models because the air bag system may not properly detect a smaller occupant in the passenger seat. Improper detection may cause the front passenger airbag not to deploy in the event of a crash, increasing the risk of injury to the front passenger. Dealers will update the occupant classification software to correct this concern. The Hyundai recall number is 105.
