On the 2024 BMW X4, recall 23V770 includes certain 2024 X4 vehicles. BMW SIB 32 04 23 describes an internal steering-gear component that may not have been properly tightened during assembly, potentially causing excessive noise, especially when parking or making tight turns; NHTSA notes a loose steering gear can cause loss of vehicle control. A VIN check is needed; noise alone cannot confirm this defect.

Common Symptoms

  • Unusual noise from the steering gear, especially when parking or in tight turns

How to Fix

Check the VIN for recall 23V770. For affected vehicles, BMW replaces the complete steering gear and initializes the electromechanical steering using the prescribed diagnostic procedure. Do not attempt to cure the recalled assembly by retightening accessible bolts. Have abnormal steering noise, vibration or control problems professionally assessed; arrange recovery if the vehicle is unsafe to drive.

On the 2019-2025 BMW X4, the G02 X4's cooling system uses plastic hoses, connectors and quick-disconnect fittings, and X4 reliability guides report slow coolant leaks at plastic parts such as the expansion tank and thermostat housing that can escalate if ignored. Separately, BMW service bulletin SIB 17 03 20 covers coolant leaks from quick-disconnect coolant lines whose O-rings do not seal at or below -15C / 5F, on the G01 X3, G02 X4, G05 X5 and G07 X7 built up to March 31, 2019. This is a platform-wide B46/B48/B58 cooling system, shared with the X3 and 3 Series.

This issue also affects: BMW 2 Series, BMW X2, BMW Z4

Common Symptoms

  • Low coolant warning that keeps returning
  • Sweet coolant smell after driving
  • Crusty residue at hose fittings with no visible drip
  • Temperature gauge climbing
  • Heater blowing cool at idle

How to Fix

Locate the coolant leak using the BMW procedure for the exact engine and cooling circuit. SI B17 03 20 covers listed vehicles built through March 31, 2019 with a confirmed leak when ambient temperature is at or below −15°C (5°F). For that condition, replace all hoses specified in the applicable vehicle/engine attachment if any listed quick disconnect shows coolant loss. Do not extend that grouped replacement rule to every adjacent connector or later X4 solely because it is plastic or aged. Confirm correct parts and coolant by VIN, and do not continue driving with overheating or significant coolant loss.
