Transmission

• 6-Speed DCT
  • Clutch Pack Failure: Description/Symptoms: The clutch pack is responsible for engaging and disengaging the gears in the transmission.

Summary: While the 2018 Hyundai Ioniq is a generally reliable vehicle, there have been some reported issues with the engine, transmission, and suspension. The majority of these issues are relatively minor and inexpensive to fix, while more severe issues such as timing chain failure or clutch pack failure can be costly. Overall, the issues reported for the Ioniq are not widespread and do not appear to affect its overall reliability or performance.
