BMW X5 steering wheel won't lock, preventing car start on BMW X5

Some BMW X5 owners report experiencing issues with the steering wheel not locking, which can prevent the car from starting. This problem may be linked to the ignition cylinder, as both the steering wheel and starting system depend on it. Potential causes for the steering wheel's failure to lock include a defective detent, damaged cog, faulty actuator, incorrect steering wheel operation, malfunctioning electric locking mechanisms, a bad car computer, a loose steering wheel, or the key not fully releasing. When the steering wheel lock fails, it can immobilize the steering wheel, making it challenging to steer even with the ignition on. Some owners find that problems with the steering lock can lead to difficulties in locking or unlocking the steering wheel, causing it to remain locked when the key is turned fully. In certain cases, attempting to turn the steering wheel back and forth does not resolve the issue, suggesting a more complex problem. It is recommended that affected owners have their steering lock system inspected by a qualified mechanic to diagnose and address the underlying issues effectively.
