2012 Hyundai Genesis stalls in 2nd or 3rd

stalls in 2nd to 3rd gear sometime very annoying machnic cant fine problem

Is the check engine light on? Any diagnostic codes? A problematic torque converter lock-up clutch could cause it, if it stalls when in 2nd or 3rd when slowing down. If you can supply more info, folks here may have some ideas. Did this start to happen after some other work was done for example? Have all the fluids been checked? Any routine engine or transmission maintenance behind schedule?

There is a TSB on transmission issues with this model (and several others, and years), especially with shifting. Google it, it’s an eyeopener.

I would hope that after one year the problem has been solved .
