BMW M60 xDrive

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.

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.

Same production issue as Gen5 Single. Heat exchanger valve leaks coolant. BMW replaces under warranty, but lengthy workshop visits.

Symptoms: Coolant loss, fault message, reduced charging performance

Vibrations between 70 and 110 km/h when accelerating and during regenerative braking. BMW carries out a service measure (disassemble front axle, replace bolts). Problem often only reduced, not fully resolved.

Symptoms: Shuddering in steering wheel and seat between 70–110 km/h under load; vibrations also during deceleration (regeneration); occurs from around 10,000 km.

Particularly on the i4 M50, vibrations emerge from the front drive unit that intensify at high speeds and under engine braking. Caused by imbalance or bearing tolerance issues in the front EDU.

Symptoms: Droning or vibration from the front motor area above 100 km/h; vibrations increase under regenerative braking; felt through steering wheel and pedals.

The Continental Integrated Brake System (IBS) can lose hydraulic brake assist due to signal interference, causing ABS and DSC to drop out.

A defectively manufactured double cardan joint in the steering spindle can fracture in rare cases, making the steering heavy or unresponsive.

Some i5 units have reported complete drive failure with the message 'STOP. DRIVE FAULT'. Causes include defective rotor position sensors, loose HV cable connections, or a faulty 12V battery.
