Why does Cadillac's power steering prompt 'Please drive carefully'?
2 Answers
Here are the specific reasons why Cadillac's power steering prompts 'Please drive carefully': Insufficient battery power: After prolonged use, the battery's internal aging and wear can lead to insufficient stored power. Issues with the power steering system: Occasional fault prompts may be caused by poor contact in the control circuit connectors or modules of the power steering system. Problems with the power steering pump or hydraulic lines: Power steering issues may indicate problems with the vehicle's power steering pump or hydraulic lines, which could result in sudden resistance in the steering wheel or an inability to turn. First, check the quality of the oil in the pump and whether the pipelines are clogged. For electronic power steering, verify if the power supply voltage is sufficient and whether the circuit connectors are oxidized due to insufficient power.
When I saw the Cadillac display the message 'Power Steering, Drive with Care,' my first reaction was to slow down and pull over immediately. This situation is most likely due to an issue with the electric power steering system—perhaps the torque sensor behind the steering wheel is faulty, or the motor in the steering gear has stopped working. The last time I encountered this, the steering wheel felt as heavy as lifting a brick, especially when making U-turns. In fact, control module malfunctions are also quite common; if it fails to receive signals from the sensors, it will directly limit the power assistance. The most dangerous scenario is a sudden loss of power assist, particularly on the highway, so never force yourself to keep driving—contact the dealership right away. Also, remember to check the fuse box—sometimes it might just be a small blown fuse.
