In brief, the 2015 Chevy Traverse does not use power steering fluid. It relies on electric power steering (EPS) instead of a hydraulic system.
That means there is no traditional power steering fluid reservoir to check or fill. Steering assist is provided by an electric motor and a control module, powered by the vehicle’s electrical system and battery, rather than by hydraulic pressure from a pump.
What type of power steering does the 2015 Traverse use?
The 2015 Traverse uses electric power steering (EPS). This system uses an electric motor mounted to assist steering and is controlled by sensors and a central control module. Unlike older hydraulic systems, there is no belt-driven pump or fluid to service.
Maintenance considerations for EPS-equipped vehicles
Because the Traverse’s steering relies on electricity rather than hydraulic fluid, maintenance and diagnostics differ from older, fluid-based systems. Here is a quick overview of what matters for this setup:
- No hydraulic power steering fluid reservoir exists to check or top up.
- There is no traditional power steering pump to service; assist comes from the electric motor and steering-control module.
- Watch for warning indicators such as EPS or steering-related fault messages on the instrument cluster. If these appear, have the system diagnosed with a scan tool and inspected by a qualified technician.
- Electrical system health matters: a healthy battery and charging system support consistent EPS performance, since the system draws from the vehicle’s electrical supply.
In summary, routine maintenance for the 2015 Traverse focuses on the electrical system and any warning indicators rather than fluid levels. If you experience heavy steering, intermittent assist, or a steering warning light, seek professional diagnosis to assess the EPS control module, sensors, and battery condition.
Summary
The 2015 Chevy Traverse uses electric power steering, not hydraulic power steering. There is no power steering fluid to check, and maintenance centers on the electrical system and diagnostics rather than fluid maintenance. If steering issues arise, consult a GM-trained technician to evaluate the EPS system and related components.
