Recalls for the 2006 Hyundai Sonata: 11
Water may enter the Anti-lock Brake (ABS) Module and result in an electrical short . 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.
Road salt and water can enter portions of the rear crossmember, leading to corrosion of the crossmember steel. This may lead to detachment of one of the rear control arms. Control arm separation may suddenly change the rear wheel alignment, affecting the handling of the vehicle, increasing the risk of a crash.
A malfunctioning stop lamp switch may cause the brake lights to fail to illuminate when the brake pedal is depressed or may cause the brake lights to remain illuminated when the brake pedal is released. Any of these malfunctions could lead to a crash.
The stop lamp switch in the affected vehicles may malfunction. A malfunctioning stop lamp switch may cause the brake lights to not illuminate when the brake pedal is depressed or may cause the brake lights to remain illuminated when the brake pedal is released. Any of these malfunctions, alone or in combination, may lead to a crash.
These headlamps fail to conform to the requirements of federal motor vehicle safety standard no. 108, "Lamps, reflective devices, and associated equipment." These lamps do not contain the required amber side reflectors. Decreased lighting visibility may result in a vehicle crash.
The purpose of the OCS is to disable the right passenger seat front air bag when it detects the presence of a child restraint system or small child in the right front seat. The right front air bag is disabled to prevent injuries to a child that may result from a right front air bag inflation during a crash. Misclassification of a small stature adult as a child in the right front passenger seat may cause the right front air bag to not inflate in an accident that merits air bag deployment and may result in injury to the right front occupant.
These headlamp assemblies may not have been aligned properly and fail to conform to the photometric requirements of federal motor vehicle safety standard no. 108, lamps, reflective devices, and associated equipment. Improper aiming of the headlamp may result in poor visibility possibly resulting in a vehicle crash.
On certain passenger vehicles, the air bag warning label installed on the sunvisors had lost adhesion to the sunvisors and had distorted or separated from the sun visors. If the labels are distorted or missing, the driver or front seat passenger will not have information available that may help protect them in the event of a crash.
On certain passenger vehicles, the inner bezels of the headlamps were not properly assembled which may cause the turn signal lenses to be improperly positioned. An improperly positioned turn signal lens may reduce the intensity of the turn signal illumination, reducing its visibility to oncoming traffic, which may result in a crash.
On certain passenger vehicles, the front seat belt may interfere with the manual seat back recliner knob and could cause the front manual seat back recliner to inadvertently release. The inadvertent release of a front seat back recliner may result in injury to vehicle occupants.
On certain passenger vehicles equipped with 3.3 liter engines and electronic stability control (ESC), the ESC may have been programmed to be oversensitive to the onset of oversteering while driving on banked curves, causing inadvertent application of the front outside brake when ESC activation may not be needed. This may cause the vehicle to slow and may affect the path that the vehicle is traveling. Brake application caused by inadvertent ESC activation may result in a crash.
