Rear Combination Lamps Fail to Comply With Safety Stndards

certain vehicles fail to comply with the stop lamp and reflector requirements of Federal Motor Vehicle Safety Standard # 108 "Lamps, Reflective Devices, and Associated Equipment" This may result in inadequate  illumination and may lead to an accident. Dealer will replace the rear combination light assembly free of charge. The Campaign # is 06V395000

Child Seat Anchors May Not Be in the Correct Location

On 137 vehicles, the lower child seat anchors in the rear seat do not meet the location requirement as stated by the Federal Motor Vehicle Safety Standard, and may cause difficulty securing some child seats. If a child seat is not secured, there is an increased risk of injury in a crash. Dealers will replace the lower seat anchor brackets with modified ones. The recall began on October 17, 2005.
