P0601 on Hyundai by Model
Hyundai Creta(1 issue)
- 7-Speed Dry DCT Failures on 1.4 T-GDI (Clutch Actuator, Overheating, Loss of Drive)2020-2023
The 1.4L turbo-petrol SU2 Creta's 7-speed dry dual-clutch transmission has multiple well-documented failures in Indian stop-and-go traffic: clutch actuator failure (logged as DTC P060194), the gearbox refusing to engage even-numbered gears until restart, transmission-overheat warnings in crawling traffic, and judder or delayed engagement from standstill. Team-BHP ownership threads document cars failing within months of delivery and failing again a year after dealer repairs, with Hyundai handling cases reactively rather than via recall. Out-of-warranty repairs are expensive — a full gearbox replacement runs roughly INR 80,000 to over 1.2 lakh.
