A number of complaints have been lodged about problems with Hyundai’s 7 speed DCT transmission.  A class action has been filed.  The new transmission was designed to improve fuel consumption and reduce CO2 emission as compared to a conventional six-gear automated transmission.  The new transmission features two clutches that transfer engine power into the gear train.

Reality has been difference than the promise.  Many owners complain of a failure to shift, stalling, delayed acceleration, or loss of power.
