APRIL 2009 --   Hyundai is recalling 531,894 MY 2006-2007 Accent, Entourage, Sonata, MY 2007 Azera, Elantra and Santa FE, MY 2005-2007 Tucson and MY 2007-2008 Veracruz vehicles. 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. A stop lamp switch malfunction may also affect the operation of the brake-transmission shift interlock feature so the transmission shifter would not be able to be shifted out of the park position. It may also cause the electronic stability control (ESC) malfunction light to illuminate, and it may not deactivate the cruise control when the brake pedal is depressed. Any of these malfunctions, alone or in combination, may lead to a crash. Dealers will replace the stop lamp switch free of charge. The recall began on April 23, 2009. Owners may contact the Hyundai Customer Assistance Center at 1-800-633-5151. This recall was the result of a Preliminary Evaluation conducted by the Office of Defects Investigation.  09V-122
