Yes. The 2013 Chevrolet Malibu uses electric power steering (EPS) rather than a traditional hydraulic system.
In 2013, GM equipped many midsize Chevrolets with electric power steering to improve efficiency and enable speed-sensitive steering assist. EPS replaces the hydraulic pump and fluid with an electric motor-powered system controlled by sensors and a dedicated control module, delivering variable assist without the need for a power steering fluid reservoir.
How EPS works in the 2013 Malibu
The EPS system relies on a motor integrated with the steering gear or rack, plus a torque sensor and electronic control unit. It provides varying levels of assist depending on speed and steering input, which helps improve fuel economy and steering feel while allowing diagnostics if something goes wrong.
Signs that your Malibu has EPS
To confirm on your specific car, check for these indicators.
- No power steering fluid reservoir or hydraulic high-pressure lines typically associated with hydraulic systems.
- An electric motor mounted on or connected to the steering rack or gear, with wiring leading to a control module.
- A dashboard warning such as "Service EPS" or "Electric Power Steering" appearing at startup or during driving.
- Owner’s manual or vehicle documentation indicating EPS as the steering system.
These indicators can help confirm EPS, though if you’re unsure, a dealer or qualified mechanic can verify by inspecting the steering assembly or scanning the vehicle’s control modules.
Maintenance and common issues
EPS typically requires less routine maintenance than hydraulic systems since there’s no fluid to check. However, electronic or sensor faults can trigger warnings and affect steering assist. Battery health is important because the EPS control module relies on a stable electrical supply, so a weak battery can cause intermittent assist or warning messages.
- Common signs: warning lights such as "Service EPS," stiff steering at low speeds, or erratic assist.
- Diagnostics: performed through the vehicle’s onboard computer; repairs may involve the EPS motor, torque sensor, or control module, usually at a dealership or shop with GM tooling.
- Electrical considerations: ensure the 12-volt battery and charging system are healthy to support EPS operation.
Overall, the 2013 Malibu’s EPS is designed for reliability, but electronic systems can experience faults just like any other modern car component. Regular checks during maintenance can help catch issues early.
Summary
Bottom line: The 2013 Chevy Malibu uses electric power steering, not hydraulic. If you’re evaluating a used model or troubleshooting steering behavior, look for signs of an electric motor near the steering rack, absence of power steering fluid lines, and any EPS-related warnings on the dash. For VIN-specific confirmation, consult a GM dealer or service portal.
