The first sports utility vehicle from Korean automaker Hyundai, the Santa Fe has been in production in the United States since the 2001 model year. The 2003 Hyundai Santa Fe saw significant improvement over previous models, including a more powerful V6 engine and computer-controlled four-wheel drive. Hyundai also offers a keyless entry system for the 2003 Santa Fe that you can program to lock or unlock your vehicle from yards away.
