The main reasons for Mercedes-Benz power steering system failure: 1. Aging or damage to hydraulic system components 2. Insufficient or contaminated hydraulic oil 3. Electrical failure in the electric steering system 4. Wear of belts or pulleys 5. Mechanical problems in the steering system 6. Inadequate maintenance or improper use

Open the owner's manual and find the vehicle specifications or technical parameters section. Generally, the type of power steering system will be listed here. If the manual specifically mentions "hydraulic power steering system" or "electronic power steering system", then you can determine the vehicle's equipment.

Cadillac first introduced power steering in its production cars in 1952. At that time, power steering technology had been relatively mature, especially after Chrysler launched the first mass-produced car equipped with a hydraulic power steering system in 1951

Hydraulic power steering systems require oil because hydraulic oil is the primary medium of energy transfer. In this system, the pressure generated by the hydraulic pump needs to be transmitted through hydraulic oil.

Specifically, Honda first equipped its North American version of the Honda Accord with a hydraulic power steering system as standard in 1982, which was the time node when Honda first adopted power steering technology on a large scale.

Reasons for noise in the hydraulic power steering system: 1. Insufficient hydraulic oil or oil mixed with air 2. Power steering pump failure 3. Steering rack failure 4. Poor quality or deterioration of hydraulic oil 5. Loose pipes or joints 6. Excessive pressure caused by the steering wheel hitting the bottom

Common faults of hydraulic power steering are: 1. Hydraulic oil leakage 2. Hydraulic pump failure 3. Steering power reduction or loss 4. Steering wheel vibration or abnormal noise 5. Steering wheel automatic return failure 6. Steering failure or loss of control

From the late 1950s to the 1960s, more and more American automakers began to equip their models with power steering systems. During this period, power steering gradually evolved from an optional configuration for luxury models to a standard configuration for mid-to-high-end models.

If the steering rack leaks seriously, the owner may find obvious oil traces under the vehicle or near the steering rack. These oil traces are usually light yellow or amber in color and have a certain viscosity.

Based on the above-mentioned steering systems, the most advanced steering system is undoubtedly the steering-by-wire system (Steer-by-Wire, SbW). The steer-by-wire system is a fully electronic steering system that does not rely on mechanical connections.
