Engine Overview

The BMW iX I20 is available with 3 engine variants — from 204 to 660 hp. 1 variants had engine changes — the model year is crucial.

M60 · Electric· 619 PS
2022 2026

Twin-motor variant of the Gen5 drivetrain with AWD and enormous system output. Up to 660 hp in the M70 version. The high-voltage system and cooling circuit are complex to service.

  • !! Recall: incorrectly manufactured Combined Charging Unit (CCU)

    The high-voltage combined charging unit (CCU) was incorrectly installed in a production batch. A loose component interrupts current flow and can shut down drive while driving. Affected: iX xDrive50, iX M60, i4 M50 (June–September 2022).

    Symptoms: Sudden loss of drive while moving; intermittent high-voltage fault messages; vehicle won't restart after shutting down.

  • !! Recall: manufacturing defect in HV battery cells (fire risk)

    Manufacturing defect in HV battery cell modules (production 07.2021–02.2024). Frame structure can crack, shut down the high-voltage system, or cells can overheat to the point of fire risk. Affected: i4 M50, iX M60, i7 M70.

    Symptoms: Sudden loss of drive; HV battery warning; in extreme cases smoke or fire at the battery.

2021 2026

Fifth generation of the BMW electric drivetrain with a single motor. High efficiency through an electrically excited synchronous motor without rare-earth magnets. Watch the 12V battery and control unit software.

  • !! Faulty switching valve in cooling circuit (Vitesco) from 30,000 km

    A Vitesco switching valve (64119462114) in the cooling circuit fails, especially in frost. Coolant runs out before the warning light activates. BMW temporarily imposed a global delivery stop on new i4s.

    Symptoms: Coolant puddle under the car; heater fails before warning light illuminates; coolant level warning appears too late.

  • !! Recall: software algorithm shuts down high-voltage system

    A software bug in the HV system monitoring triggers a preventive drivetrain shutdown even when no actual hazard exists. Vehicle loses drive within 15–20 seconds. BMW recalled 70,852 vehicles (i4/iX/i5/i7, MY 2022–2025).

    Symptoms: Warning 'High-voltage system fault' followed by loss of drive; steering and brake assist remain active; car coasts slowly to a stop.
