problem #1

Rio 4-cyl

  • Automatic transmission
  • 23,500 miles
Dealer changed computer, wiring harness, 2 injectors, plug, timing belt, sensor and replaced comes switches. Bought a 2004 Kia Rio in March 2005. It has been in the shop for the past 3 weeks. The consumer picked the car up at the shop, and it didn't make it off the lot before the car broke down again. Dealer offered me a rental car. Went back one week later to pick up the car and only went two miles before the car broke down again. Took the car back to dealer, and requested another car just like the one that I had a 2004 Kia Rio. Dealer said could not trade the car without refinancing it. They did finance the house for the first car but refused to with the second car. Why cant the dealer finance the second car as they did the first?
