Why does the Cruze steering wheel suddenly become immovable?

[VanSawyer]

Here are the reasons why the Cruze steering wheel suddenly becomes immovable: 1. Key signal transmission error: This causes the signal to fail to reach the computer or the computer receives an incorrect signal, preventing normal operation and triggering the steering wheel's self-locking function. 2. Issues within the steering system: Due to fluid leakage in the steering system, air is not completely expelled from the system. If the steering pump operates for a long time without sufficient oil, it can lead to severe wear, reducing the performance of the steering system. Below is related information about the steering wheel becoming immovable: 1. Protection: The phenomenon of the steering wheel suddenly becoming very tight and immovable is more common in vehicles equipped with electronic steering systems. The power-assisted system uses an electronic power-assisted form. When repeatedly turning the steering wheel while stationary or at low speeds, the load on the power-assisted system is extremely high, easily causing the steering gear to overheat and activate protection, resulting in heavy steering. It can return to normal after cooling down, which is a normal phenomenon. 2. Anti-theft: After the vehicle is turned off, if the steering wheel is parked at a certain angle where the key can only be twisted to ignite but cannot unlock, the steering wheel will become immovable. The steering wheel will automatically lock, which is a simple anti-theft function.

I summarized this from experience with automotive steering systems. A common issue in the Cruze is the sudden inability to turn the steering wheel. The main cause is aging mechanical components, such as rusted or seized steering column bearings, especially in older vehicles parked in humid environments where corrosion can easily cause the wheel to lock. Power steering system failures are also common. Some Cruze models use hydraulic power steering, where a failed pump or clogged fluid lines can make the steering wheel heavy or even lock up. In electric power steering versions, issues like faulty sensors or control module errors can interrupt power assistance, making steering difficult. Additionally, faults in the anti-theft steering wheel lock mechanism can directly lock the wheel if accidentally triggered. These dangerous situations can affect driving safety. If you encounter such an issue, immediately turn on hazard lights, stop the car for inspection, and avoid forcing the wheel. Have it diagnosed at a professional repair shop—after all, steering problems while driving are terrifying. Regular maintenance, including steering fluid changes and rust prevention, should not be overlooked.
