Yes; in most cars you can still steer without electric power assist, but the steering will be much heavier and handling can become more challenging. If EPS fails, pull over safely and have the vehicle inspected—do not press on with the issue for long distances.
Understanding EPS and potential failure modes
How electric power steering works
Electric power steering uses a motor to assist steering input, reducing the effort required to turn the wheel at all speeds. A controller reads steering angle, torque, and vehicle speed to adjust the level of assistance. When the system is working, you feel a light, predictable response, especially at low speeds and during parking.
Common failure indicators
When EPS begins to fail, you may notice one or more of the following: the steering feels unusually heavy or stiff, a warning light or message appears on the dashboard (for example, “Service EPS” or “Power Steering”), and the steering may become erratic or intermittently unresponsive. Some cars enter a degraded or limited-assist mode to let you reach a safe location, while others may lose assist entirely.
The net effect is that you can still steer, but with reduced precision and increased effort, which can affect your ability to react quickly in an emergency.
Driving with a compromised EPS: what to expect
Many modern vehicles retain some steering capability even if the electric assist fails, but the experience varies by model and the presence of any limp-home or degraded-mode software. Experts emphasize that you should treat a loss of EPS as a potentially dangerous fault and return to service promptly.
- Steering effort is significantly higher, especially at low speeds or during tight maneuvers like parking.
- Steering response may feel less precise, with reduced road feel and slower turn-in.
- Warning indicators on the instrument cluster may stay illuminated until the fault is cleared.
- In some vehicles, a degraded-mode or “limp home” setting may keep you moving, but with limited steering assist.
Even when you can keep the vehicle moving, the extra effort and potential for delayed or imperfect responses increase the risk of a collision, particularly in adverse weather or busy traffic.
What to do if EPS goes out while you’re driving
If you experience EPS failure, follow these steps to maximize safety and minimize risk.
- Ease off the accelerator and slow gradually; stop in a safe, well-lit area as soon as feasible.
- Turn on hazard lights to alert other drivers, then check the dashboard for warnings or messages.
- Do not ignore the problem or attempt to “reset” the system by restarting the engine repeatedly.
- If you must continue driving to reach a safe location or service, do so slowly and avoid sudden or aggressive maneuvers. Drive with both hands on the wheel and anticipate longer stopping distances.
- Seek professional service promptly. Have the EPS system diagnosed, including the motor, sensors, wiring, and control modules, as well as any related fuses or relays.
After a fault is confirmed, schedule repairs as soon as possible. In many regions, driving with a failed EPS can be illegal if it creates an unsafe condition or triggers warning lights, so follow local guidance and manufacturer recommendations.
Longer-term considerations: maintenance and safety planning
Proactive maintenance can reduce the chance of an EPS failure and help you feel more confident if a fault occurs. Here’s what to keep in mind.
- Pay attention to warning lights promptly; diagnostics may reveal a faulty sensor or motor issue before steering becomes dangerous.
- Keep tires properly inflated and aligned, as tire condition can compound steering effort and handling issues when assist is reduced.
- Follow the manufacturer’s recommended service intervals for EPS-related components and software updates.
- Know your vehicle’s response in degraded mode if your car supports it; practice gentle steering and braking in a safe, controlled environment
Consult your dealership or a qualified mechanic if you notice persistent stiffness, unusual noises, or inconsistent steering assist. Prompt attention can prevent an EPS fault from becoming a safety-critical event.
Summary
Electric power steering failures are typically not catastrophic. Most cars will still steer without assist, but with heavier steering and reduced precision. You should reduce speed, seek a safe place, and obtain service promptly. Understanding how your specific vehicle behaves in degraded EPS mode, and practicing cautious driving in adverse conditions, can help you stay safer on the road.
