The day before, everything was working fine and I've no indication prior to this incident that anything was wrong with the transmission.
My 2003 Hyundai Santa Fe has no forward gear. Reverse is working fine. Why? on 2003 Hyundai Santa Fe

you could have a shift solenoid that is stuck or faulty, the linkage could be an issue, or a machanical part inside the transmission might have failed. without having some testing done it is very hard to say what happened
