Hyundai Ioniq 2017-present Drivetrain Specifications

The 2017-Present Hyundai IONIQ offers three drivetrain options: Hybrid, Plug-in Hybrid, and Electric. The Hybrid model features a 1.6L GDI engine paired with an electric motor, delivering a combined output of 139 horsepower. The Plug-in Hybrid combines the same engine with a more powerful electric motor, offering up to 29 miles of electric-only range. The Electric model is powered solely by an electric motor, producing 134 horsepower and offering a range of up to 170 miles on a single charge. All models use a 6-speed dual-clutch transmission for the Hybrid and Plug-in Hybrid, while the Electric model uses a single-speed reduction gear.

Regular maintenance for the Hyundai IONIQ drivetrain includes checking and replacing the transmission fluid every 60,000 miles for Hybrid and Plug-in Hybrid models. The Electric model requires inspection of the reduction gear oil every 75,000 miles. Additionally, the battery cooling system should be inspected annually, and the electric motor components checked for wear and tear. Hyundai recommends following the maintenance schedule outlined in the owner’s manual to ensure optimal performance and longevity of the drivetrain.

Replacing drivetrain components in a Hyundai IONIQ involves several steps. First, ensure the vehicle is securely lifted using a hydraulic jack. Disconnect the battery and remove any covers or shields to access the drivetrain. For Hybrid and Plug-in Hybrid models, drain the transmission fluid and disconnect the driveshaft before removing the transmission. For the Electric model, disconnect the electric motor and reduction gear assembly. Installation is the reverse of removal, ensuring all connections are secure and fluids are replenished. It’s recommended to consult the service manual for detailed instructions and torque specifications.

If your Hyundai IONIQ drivetrain is malfunctioning, start by checking for any warning lights on the dashboard. Use an OBD-II scanner to read error codes and diagnose the issue. Common problems include transmission slipping in Hybrid models or reduced power in Electric models. Inspect the battery cooling system and ensure all electrical connections are secure. If the issue persists, consult a certified Hyundai technician for a thorough diagnosis and repair. Regular maintenance can help prevent many drivetrain issues.

To optimize the performance of your Hyundai IONIQ drivetrain, ensure regular maintenance is performed, including fluid changes and system inspections. For Hybrid and Plug-in Hybrid models, use the Eco driving mode to maximize fuel efficiency. For the Electric model, pre-condition the battery before driving in extreme temperatures to maintain optimal range. Avoid aggressive driving and ensure tires are properly inflated to reduce strain on the drivetrain. Additionally, keep the battery charged within the recommended range to prolong its lifespan and maintain performance.
