The 2017 Nissan Altima uses electric power steering (EPS), not a hydraulic system.
Overview of the Altima’s steering system
In 2017, Nissan commonly equipped the Altima with electric power steering. EPS uses an electric motor to provide steering assist rather than a hydraulic pump driven by the engine. This arrangement can improve fuel economy and allow for variable steering assist depending on speed and driving conditions.
- Electric motor mounted on or near the steering rack or column provides assist
- Assist level is controlled by the vehicle’s electronic control unit (ECU) using steering torque and speed data
- Assistance varies with speed: more at low speeds for easier maneuvering, less at higher speeds for better road feel
- No power steering fluid reservoir or belt-driven pump is required; the system draws from the 12‑V electrical system
EPS in the 2017 Altima generally translates to improved efficiency and a modern, computer-controlled steering feel. Some drivers may notice a different sensation compared with older hydraulic setups, especially at parking speeds or during rapid lane changes.
Differences in steering feel between EPS and hydraulic systems
Electric power steering can feel lighter at low speeds and stiffer at higher speeds due to electronic control algorithms. Some drivers notice a more "numb" or resistor-like feel on center, while others appreciate the consistency and auto-adjustment during cornering and highway driving. If you’re transitioning from hydraulic PS, give yourself a few drives to adapt.
How to confirm if your specific Altima has EPS
To verify the steering type on your exact vehicle, use a quick combination of visual checks and documentation. This helps account for any variations or recalls tied to a VIN.
- Look under the hood for a conventional power steering fluid reservoir and pump; absence of these typically indicates EPS
- Check the owner’s manual or service records for references to Electric Power Steering (EPS)
- Watch for a dash warning light labeled “EPS” or “Power Steering” on startup or while driving
- Ask a Nissan dealer or use the VIN to pull a factory configuration and service history that specifies the steering system
In most 2017 Altimas, the absence of a hydraulic fluid reservoir and the presence of an electric motor near the steering assembly point to EPS. Always confirm through official documentation or a dealership diagnostic for your VIN.
Common issues and maintenance tips
Like any EPS system, the Altima’s electric steering can experience faults that affect assist or warning indicators. Being aware of typical signs helps with timely diagnosis and repair.
- Power Steering or EPS warning light appears on the dashboard
- Intermittent or complete loss of steering assist, especially at low speeds
- Unusual noises from the steering area or a perceptible stiff feel at startup
- Electrical issues related to the 12‑V battery, alternator, or wiring that affect EPS performance
When issues arise, start with a battery/charging check and inspect electrical connections to the EPS motor and torque sensors. A dealer can perform software updates or replace faulty components (sensor, motor, or control module) under warranty if applicable.
What to do if you experience steering problems
Safety comes first. If you notice sudden changes in steering assist or warning lights, take careful steps to address the issue.
First, try to steer with normal effort and move to a safe location if possible. If assist is completely lost, do not continue driving long distances; have the vehicle towed to a Nissan service center for a full diagnostic. Ask about any open recalls or firmware updates related to EPS for your VIN.
Summary
The 2017 Nissan Altima is equipped with electric power steering (EPS), offering fuel-efficiency benefits and variable assist controlled by the vehicle’s computer. EPS is generally reliable but can present warning lights or intermittent loss of assist, which are typically resolved through dealer diagnostics, software updates, or component replacement. For your exact car, verify via the owner’s manual, VIN lookup, or a Nissan technician to confirm the steering system configuration.
