E-Tech Hybrid Powertrain Hesitation and Inverter Software Faults
ModerateEngineThe 1.6-litre E-Tech full-hybrid system uses a clutchless dog-ring multi-mode gearbox and dual electric motors. On 2021 to 2023 cars, owners report noticeable hesitation, driveline snatch, or flat spots when transitioning between EV mode and the petrol engine under acceleration. In severe cases, calibration glitches in the hybrid inverter or temperature sensors trigger warning lights and drop the car into limp-home mode. Renault issued ECU/TCU recalibrations to smooth dog-clutch engagement and resolve false sensor alerts.

- Execute several brisk accelerations from 15 to 45 mph to test smoothness of hybrid power transitions
- Inspect main dealer service invoices for proof of hybrid control unit and transmission ECU software updates
- Verify that the car restarts cleanly from EV mode without driveline clunks or warning lights
