Common Problems with the
2025 BMW Z4 (G29)

The 2025 BMW Z4 (G29) has an excellent reliability record with no widely reported common faults for this model year period.

Buying Tips for 2025 BMW Z4 (G29)

  • Check the fabric soft-top for any wear marks or creases, and ensure it opens/closes silently in the claimed 10 seconds.
  • Inspect the B48/B58 engine water pump and thermostat area for slow coolant leaks, a common minor issue on modern BMWs.
  • Test the iDrive 7 digital instrument cluster to ensure it doesn't freeze or lag, verifying the car has the latest OTA software updates.
  • Verify the condition of the large alloy wheels, as the low stance makes them very susceptible to kerbing.
  • Ensure the active exhaust valves (if fitted) open and close correctly when switching between Comfort and Sport modes; they can seize with carbon buildup.
  • Check the interior trim for squeaks, particularly around the rear bulkhead where the roof mechanism meets the cabin.
