When i come to a slight uphill incline, slow down without fully stopping, and then attempt to accelerate, there are times when the transmission feels as if it is in neutral. the engine will rev up to approximately 2000 rpm but the vehicle will not accelerate for approximately 1 second. then all of a sudden, the car will accelerate forward at a rapid pace. it seems as if the transmission is in between gears and the transmission then suddenly realizes that it needs to accelerate and then will accelerate usually at a fast pace. the feeling is that of a manual transmission when the clutch is released while the engine is at a higher rpm. my car has the traditional 6 speed automatic and not the dual clutch transmission. this is an intermittent issue and the car was brought to the dealer's service department. the tech stated that the transmission was working fine and there were no new software updates for the transmission.
When leaving home the vehicle had little acceleration and poor shifting. took too much time merging into traffic. after contacting the local dealership the problem cleared up as it had done before. drove to the local hyundai dealership. obdii code read p0193.
Car at times will not accelerate from a stop for 2 to 3 seconds after acclerater is push.
