* Low Power Steering Fluid: This is the simplest and cheapest possibility. Check your power steering fluid level. If it's low, you'll need to top it off (using the correct fluid type specified in your owner's manual). A low level could indicate a leak somewhere in the system.
* Power Steering Pump: A failing power steering pump is a common cause of intermittent power steering issues. The pump might be struggling to build pressure, especially when the engine is under load. When the car is restarted, the pump might briefly regain enough pressure to work before overheating or failing again.
* Power Steering Pressure Sensor/Switch: A faulty sensor could be sending incorrect signals to the power steering control module, causing it to intermittently shut down the system.
* Electrical Issues: Problems with the power steering system's wiring, fuses, or the power steering control module itself could cause intermittent power loss. A bad connection or corroded wire could be making intermittent contact.
* Loose Belt: A loose or slipping serpentine belt (which drives the power steering pump) would cause the power steering to fail. This is relatively easy to check visually.
Cost to Fix:
The cost varies dramatically depending on the cause:
* Low Fluid/Leak: This could be very inexpensive – just the cost of the fluid and potentially a new cap or minor repair to address the leak if one is found.
* Power Steering Pump: Replacement can range from $200 to $500+ depending on the labor costs in your area and whether you buy a new or remanufactured pump.
* Pressure Sensor/Switch: A replacement sensor is relatively inexpensive (around $50-$100), but labor costs will add to the bill.
* Electrical Issues: This could range from very inexpensive (a blown fuse) to very expensive (a faulty control module requiring replacement). Diagnosing electrical problems can be time-consuming, adding to the labor costs.
* Loose Belt: This is typically a minor repair, mostly labor for the mechanic to check and replace the belt.
Recommendation:
I strongly advise taking your Saturn Ion to a qualified mechanic for diagnosis. They can properly inspect the power steering system, identify the root cause of the problem, and provide an accurate estimate for repair. Attempting DIY repairs without proper knowledge could potentially worsen the issue or cause injury. Don't drive the car if the power steering is unreliable, as it can be dangerous, particularly at low speeds or when parking.
