EDC vs PowerShift: which gearbox is more reliable?
According to our risk index, the EDC gearbox carries less risk than the PowerShift gearbox: 38/100 (moderate risk) versus 72/100 (high risk). The EDC gearbox has 3 documented serious faults, the main one being «EDC gearbox overheating and safety neutral»; the PowerShift gearbox has 3 documented serious faults, the main one being «Juddering, hesitation and slipping of the dry clutch (DPS6)».
The index (0–100) weights the severity and frequency of the three most serious documented faults. How it is calculated
Is the EDC gearbox reliable?
The EDC covers several Renault dual-clutch gearboxes: the EDC6 (Getrag DC4 dry clutch on most entry-level engines, or DW6 wet clutch on higher-torque ones) and the wet-clutch EDC7, introduced in 2016 to fix the low-speed judder of the earlier unit. Many owners document early clutch wear, overheating that forces a safety neutral, and control electronics faults, especially on the EDC6.[1][2]

Ford PowerShift covers two different dual-clutch gearboxes: the dry-clutch DPS6, fitted to the Fiesta, Focus, B-MAX, EcoSport and C-MAX; and the oil-bath 6DCT450, fitted to higher-torque diesels in the Focus, Kuga, Mondeo, S-MAX and Galaxy. The DPS6 has racked up thousands of complaints about juddering and slipping, with a US court settlement in 2020; the 6DCT450 is more robust, but needs its oil changed every 50,000-60,000 km to avoid wearing out the clutch.[3][4][5]
