The automatic transmission slips and then violently kicks into first gear when starting out. It will also slip while driving along and then kick back into gear with a bang sound. These slips seem to occur when the engine is cold( just started and temperature gage reads at or near c). I have taken it to the dealer 3 times over the years and they tell me they find nothing wrong. The problem recurs at least weekly.
I have a 2010 Hyundai Santa Fe. The transmission slips and I get a hard shift with a loud bang when shifting from 1st to 2nd or 2nd to 3rd. It seems to do this when the transmission is cold but it does it even when warm. I had mine in 3 times for repair with a new transmission on the last repair. The new transmission is the same as the original one. Hyundai knows about this and they knew about when I bought the car. I should have been notified when I was buying the car - not finding out after the fact. The dealer gives me the deer in the headlights look when I complain about this like they have never heard about it before.
