Facing a “Service Power Steering” message on your Chevy Malibu dashboard can be disconcerting. This is especially true if you notice a sudden loss of power steering, which results in a steering wheel that’s tough to turn. This warning is the car’s way of alerting you to a significant issue with the power steering system.
Often, the cause of the power steering problem may relate to a failure in the electronic components. Many Chevy Malibu models are equipped with an electric power steering system (EPS). Unlike traditional hydraulic systems, EPS doesn’t rely on fluid but employs electric motors to assist in steering. These motors can be susceptible to electrical and sensor-related faults.
When this message appears, it is crucial to take your vehicle to a professional for a thorough diagnostic. This will help pinpoint the exact cause and rectify the issue to prevent further damage or driving risks.
Besides the technical aspects of fixing the power steering issue, it’s good to have an estimate of the potential costs involved. The repair costs are variable and can differ based on parts and labor pricing in your area. Your mechanic will provide a more accurate expense sheet after assessing your vehicle’s problem. Regardless, securing the functionality of your power steering system remains a top priority for the safety of your driving experience.

Identifying Common Power Steering Issues in the Chevy Malibu
Chevrolet Malibu owners often face challenges with the power steering system, evident from warning signals and diagnostic trouble codes, primarily in models like the 2008 and 2012 Malibu. These signs are crucial to understanding and addressing steering issues early.
Interpreting the Power Steering Warning Signals
When the power steering warning light illuminates, or the dashboard displays a “Service Power Steering” or “Service Power Steering, Drive with Care” message, it indicates a problem within the steering system.
Malibu drivers have reported sudden losses of power steering, which can result in a heavier steering wheel, challenging vehicle handling. Additionally, if the Electronic Stability Control (ESC) indicator lights up, it further signifies that the steering assistance could be compromised.
Diagnosing Power Steering Problems Through Error Codes
Retrieving error codes with an OBD-II scanner is a direct method to diagnose power steering problems. Common codes related to power steering issues in the Malibu include:
| Error Code | Description |
| C0545 | Steering Wheel Torque Input Sensor Circuit |
| C0561 | ABS Related Issues Affecting Power Steering |
| U2100 | CAN Bus Communication Error |
| P Codes | Powertrain-Related Errors Impacting Steering Function |
Chevrolet Malibu models equipped with electric power steering (EPS) may experience a variety of these codes. When such codes appear, it often signifies the need for a thorough check or potential repair of the steering system components. It’s beneficial for vehicle owners to be aware of these codes to ensure prompt action is taken for any necessary maintenance or repairs.
Steering Mechanism in the Chevrolet Malibu
In our experience with the Chevrolet Malibu, the steering mechanism, which is the system responsible for the control and direction of the vehicle, can include either an electric power steering (EPS) system or a more traditional hydraulic power steering setup. Understanding the type your Malibu has is crucial to troubleshooting and servicing its steering capabilities.
Electric vs Hydraulic Power Steering Systems
Electric Power Steering (EPS)
In recent Malibu models, the EPS system has replaced the conventional hydraulic power steering. Without the need for hydraulic fluid, the EPS system uses an electric motor, which is controlled by a power steering module. The torque sensor in the steering column detects the driver’s steering force and assists accordingly.
Hydraulic Power Steering
Older Malibu models may be equipped with hydraulic power steering systems which utilize a pump driven by the engine through belts. The hydraulic system relies on fluid to transmit the steering effort from the steering wheel through the system’s connections to the wheels.
Components of the Malibu Steering Assembly
| Component | Function |
| Steering Wheel | The primary input device the driver uses to control direction. |
| Steering Column | Connects the steering wheel to the steering mechanism. |
| Electric Motor (EPS) | Provides assistance to the steering mechanism. |
| Torque Sensor | Detects the amount of torque the driver is applying to the steering wheel. |
| Hydraulic Pump (Hydraulic systems) | Generates pressure to assist steering in hydraulic systems. |
| Belts (Hydraulic systems) | Connect engine power to the hydraulic pump. |
When we service our Malibu’s steering system, we always verify the Vehicle Identification Number (VIN) to determine the specific type and components of the steering assembly. This ensures we are diagnosing the correct system and sourcing the appropriate parts or fluids. For EPS-equipped Malibus, focus is typically on electronic diagnostics and sensor integrity, while hydraulic systems might require inspection of fluid levels, pump function, and belt condition.
Maintenance Procedures for Enhancing Steering Performance
In addressing the performance of a Chevrolet Malibu’s steering system, we focus on preventative maintenance and efficient troubleshooting. We emphasize the significance of regular service intervals and effective diagnostic approaches to uphold the integrity and responsiveness of the power steering.
Regular Checks and Service Intervals
Service Power Steering: Our oil changes conform to GM dealer recommendations, which often include checking the power steering system. We monitor fluid levels and the condition of the drive belt to ensure appropriate tension and integrity, thus avoiding low fluid level issues that can lead to hard steering.
| Maintenance Item | Service Interval |
| Power Steering Fluid Check | Every Oil Change or at least twice a year |
| Drive Belt Inspection | Every 10,000 miles |
| Steering System Inspection | With each service visit |
We also advise regular checks of the brakes and transmission, as these systems can affect steering performance. High pressure in the power steering system should be inspected and reset by qualified technicians to guarantee proper function and extend the life of the vehicle.
Troubleshooting Steering System Failures
First, we assess the situation to determine if the issue is due to low fluid levels, a malfunctioning pump, or a deeper system failure.
In case of persistent steering problems, we consult the service bulletin for guidance on known issues and recommended fixes.
If the power steering assist is lost, we consider the vehicle’s mileage and service history. Some models may be subject to extended coverage for electric steering issues. In such cases, we suggest taking the vehicle to a certified dealership for a comprehensive diagnostic and repair service. It is important to have any irregularities checked promptly to prevent further damage to the steering system.
Warranty and Recalls for Power Steering Issues
We should be aware that Chevrolet has provided a special coverage adjustment for some electric power steering issues.
For the Chevy Malibu, this special coverage could extend up to 10 years or 150,000 miles from the initial purchase date.
It is crucial for owners to check with an authorized GM dealership to confirm if their vehicle is eligible for this extended warranty.
When considering recall information, we turn to the records of NHTSA.
Recalls related to the power steering system in some GM models have been issued.
Owners can visit the NHTSA database or contact their local dealership for information on recalls that might affect their Chevy Malibu.
In the context of the Chevrolet Malibu Forums, new threads often surface documenting owner concerns with power steering issues.
These threads serve as anecdotal records, highlighting the importance of monitoring both new and older thread discussions for updates on warranty and recall actions.
| Entity | Relevance |
| Recall | Check NHTSA for active recalls |
| Special Coverage Adjustment | Up to 10 years/150,000 miles (verify with dealership) |
Reviewing dealership discussions, this special coverage may not require the repair to be at a GM dealer, however, it is often preferable.
The terms of the warranty will always be the guiding factor, and it is advisable for owners to have their Chevy Malibu serviced at licensed facilities when possible.
