3 Answers
Mercedes-Benz power steering failure causes include: presence of excessive air, foreign matter, piston cylinder wear, etc. Loose connections Below are the specific causes of Mercedes-Benz power steering failure: Presence of excessive air: The power steering system contains a large amount of air, causing abnormal car steering. Foreign matter: Foreign matter in the steering hydraulic pipeline causes the steering pump flow control valve to stick. Loose connections: Loose connections in the power steering system lead to steering fluid leakage. Piston cylinder wear: Excessive wear of the steering gear piston cylinder, poor oil seal sealing, or control valve adhesion or damage.
As someone who frequently deals with cars, I often encounter power steering failures in the Mercedes-Benz GLC260, which are usually caused by issues with the Electric Power Steering (EPS) system. Specifically, it could be due to a faulty power steering motor, resulting in insufficient assistance when turning the wheel; or a malfunctioning control module that sends incorrect commands. If the steering sensor signal is lost, the system won't know where the driver intends to steer, causing the assistance to shut off completely. Additionally, unstable battery voltage or loose wiring connections can also cut power to the steering system. It's recommended to first check the battery and fuses after parking, and avoid forcing the car to drive to prevent damage to the steering gear or accidents. Regular maintenance, such as cleaning connectors and replacing aging components, can help reduce such issues. Mercedes-Benz vehicles have sensitive electronic systems, and software errors can also cause problems, so it's best to visit a dealership to scan and address fault codes.
I've been driving my Mercedes-Benz GLC260 for over two years when suddenly last month, the power steering failed completely. The steering wheel became as heavy as a rock, which was quite frightening. At first, I thought it might be due to low tire pressure, but then the dashboard warning light came on. A friend helped check and suggested it could be either a lubrication issue with the steering gear or dust accumulation on the sensor connector. I took it to the 4S dealership, where they spent half a day replacing the EPS unit, and now everything is back to normal. The lesson here is not to ignore minor unusual noises, ensure lubricant is topped up during maintenance, and avoid forcing the steering wheel. Power steering failures are more likely to occur in cold weather, and an aging battery is also a common trigger. Addressing issues promptly prevents damage to chassis components or accidents.
