Can the steering wheel still be turned if the power assist is lost?

It is not recommended to drive when the power steering fails. You should promptly reduce speed, stop the vehicle, and conduct a comprehensive maintenance inspection. The function of the automotive steering system is to control the driving direction according to the driver's intention. The steering system is crucial for driving safety, hence its components are referred to as safety-critical parts. Below is additional information: Power steering assist: Power steering assists the driver in reducing the effort required to turn the steering wheel, and it also plays a role in the safety and fuel efficiency of vehicle operation. When turning, the torque sensor detects the steering wheel's torque and intended turning direction. These signals are transmitted via the data bus to the electronic control unit (ECU). Based on the transmitted torque and intended direction data, the ECU sends commands to the motor controller, which then outputs the corresponding amount of torque as needed, thereby generating power steering assistance.
I've experienced steering assist failure once before. That time on the highway, the steering suddenly became extremely heavy - turning the wheel felt like lifting weights, my arms were shaking from exhaustion and it was easy to lose focus - truly dangerous. Personally, I think it's best not to continue driving when this happens, as it may lead to steering loss of control or suspension component damage, increasing accident risks. When my power steering failed while driving, my approach was to first slow down to a safe speed, turn on the hazard lights, gradually pull over, then call for a tow truck or mechanic assistance. During regular maintenance, I always remind them to check the power steering pump and fluid to prevent such incidents. Bottom line - safety first, don't push your luck. Paying attention to small details while driving can prevent major troubles, just make it a habit.
From years of driving experience, when the power steering system fails, the steering wheel can still be operated with great difficulty, but it's not recommended. I've tried moving slowly in the city to a repair shop at speeds below 30 km/h, which was manageable, but absolutely not feasible on highways as steering lag could cause accidents. Power steering failures can stem from various causes like a broken pump or snapped belt. Continuing to drive could worsen gear wear in the steering mechanism, leading to higher repair costs. My advice is to first find a safe place to stop and check if the fluid is low when encountering such issues. After simple troubleshooting, you might drive a short distance to a safer location, but otherwise, calling a tow truck is the safer option. For daily vehicle use, don't forget regular maintenance of power steering components to minimize failures.
