The Hyundai i20’s automatic variants, including the 4-speed auto, CVT, and 7-speed DCT, have also faced some challenges. Here are the most common problems reported by owners:

• Transmission Slippage – Occurs when the transmission unexpectedly shifts gears, leading to a loss of power and acceleration, often requiring a fluid change or software update.
• Delayed Gear Engagement – A noticeable delay when shifting from park to drive or reverse, typically resolved by checking and adjusting transmission fluid levels.
• Rough Shifting – Harsh or jerky gear changes, often due to worn-out transmission components or low fluid levels, necessitating inspection and possible replacement of parts.
• Overheating – Transmission overheating can cause erratic shifting and damage, usually addressed by ensuring proper cooling and fluid levels.
• Fluid Leaks – Transmission fluid leaks can lead to low fluid levels and poor performance, requiring seal replacement and fluid top-up.
• Torque Converter Issues – Problems with the torque converter can cause shuddering or slipping, often fixed by replacing the converter or flushing the transmission.
• Sensor Malfunctions – Faulty sensors can lead to incorrect gear selection, typically resolved by replacing or recalibrating the affected sensors.
• Software Glitches – Software issues can cause erratic transmission behavior, often corrected by updating the transmission control module software.
• Clutch Wear in DCT – Excessive clutch wear in dual-clutch transmissions can lead to slipping or rough shifts, requiring clutch replacement.
• CVT Belt Wear – Worn CVT belts can cause slipping and reduced performance, typically resolved by replacing the belt and adjusting tension.

• Warning Lights – Dashboard lights may indicate transmission issues, often due to faulty sensors or low fluid levels, needing prompt diagnosis.
• Notchy or Stiff Gear Changes – Caused by low gearbox oil or internal bearing wear, making gear shifts rough and difficult.
• Whining in Higher Gears – Often a sign of low gearbox oil or internal wear, leading to increased noise and potential damage.
• Linkage Problems – Misaligned or damaged linkage can prevent proper gear engagement, requiring adjustment or repair.
• Internal Transmission Damage – Worn components can lead to slipping gears and grinding noises, necessitating inspection and repair.
• Faulty Sensors – Incorrect signals to the transmission control module can cause erratic shifting, often resolved by sensor replacement.
