 I bought the Santa Fe in 2006, within a couple of months I was in having the Cruise control switch replaced and a year later I started having problems with the down shifting to 3rd. They changed out a sensor. In the winter of 09 it didn't want to go into drive  when cold brought it in. Couldn't duplicate so there was "nothing wrong". Still having problem. On 4/29/10 the shifting problems started again, so I brought the car back into the shop to have them say "nothing wrong" so they reset the computer. So I picked up my car and two days later I was stuck in the parking lot not able to go anywhere. Lets say it is in the shop waiting approval for new transmission!
