Your steering information system has detected a problem and is running at lower power
When your dashboard shows "steering information is reduced" or "steering information degraded," your vehicle's power steering system is still working, but the electronic information that makes steering easier has partially shut down. This is a safety feature, not a failure — your car is telling you that something in the information system needs attention before it stops working entirely.
You can still steer and drive the vehicle, but you will feel noticeably more resistance in the steering wheel, especially at low speeds or when parking. The message means one of several components in the information system has triggered a fault code, and the system has reduced its help to protect itself from damage.
This is different from a complete power steering failure. You have not lost all information — you have lost some of it. The distinction matters because it changes what you should do next and how urgently you need to address it.
Key Takeaways
- A reduced steering information message means your power steering system is partially disabled as a safety measure, not completely failed.
- You can drive the vehicle, but steering will feel heavier, especially at low speeds and when turning into parking spaces.
- The most common causes are a low power steering fluid level, a faulty steering angle sensor, or a problem with the electric information motor.
- You should have the vehicle scanned with a diagnostic tool to read the specific fault code before visiting a repair shop.
- Driving with reduced steering information is safe for short distances, but the underlying problem will not fix itself and will likely worsen.
Why your steering information reduces itself
Your vehicle's power steering system includes several parts that work together: a pump or electric motor that creates the information force, fluid or electrical connections that deliver that force, and sensors that monitor whether everything is working correctly. When one of these parts sends a signal that something is wrong, the system reduces information power to avoid damaging itself further.
Think of it as a circuit breaker. A circuit breaker does not mean your house has no electricity — it means one circuit has detected a problem and shut itself down to prevent a fire. Your steering information works the same way. The system is protecting itself, and it is also protecting you by warning you that something needs repair.
The system cannot tell you which part is broken just from the dashboard message. It only tells you that a fault has been detected. That is why you need a diagnostic scan to find out what actually triggered the warning.
The most common reasons for reduced steering information
Low power steering fluid is the single most common cause, especially in older vehicles or those with small leaks. The fluid level drops below the sensor threshold, the system detects low pressure, and information reduces. Check your power steering fluid reservoir under the hood — it is usually a translucent plastic container with a dipstick or fill line marked on the side. If the level is low, top it off with the correct fluid type for your vehicle (check your owner's manual or the cap itself for the specification).
A faulty steering angle sensor tells the system how much you are turning the wheel. If this sensor sends a bad signal, the system cannot calculate how much information to provide and reduces power as a safety measure. This sensor is usually mounted on or near the steering column and cannot be checked visually — it requires a diagnostic scan.
A problem with the electric information motor or pump means the component that actually creates the information force is not working at full power. This could be a failing motor, a loose electrical connection, or a corroded terminal. A mechanic can test this with a diagnostic tool and by checking electrical connections.
A communication error between the steering system and the vehicle's main computer can also trigger a reduced information message. This is often caused by a loose or corroded battery terminal, a blown fuse, or a wiring problem. These are usually the easiest and cheapest to fix.
What to do when ready after you see the message
First, do not panic. Your vehicle is still drivable. You have power steering — you just have less of it. Steer normally and avoid sudden movements. The heavier steering wheel will feel strange at first, but it is manageable.
If you are on a highway or in heavy traffic, continue to a safe location — a parking lot, a side street, or an exit. Do not pull over on the shoulder of a busy road. Once you are somewhere safe and stationary, turn off the engine and wait 30 seconds, then restart the vehicle. Sometimes a temporary sensor glitch will clear on restart.
If the message returns after restart, note whether it appears when ready or only after driving for a few minutes. This detail helps a mechanic narrow down the cause. Also note the exact wording of the message if it is different from "steering information reduced" — some vehicles say "power steering fault," "steering information unavailable," or "electric power steering malfunction."
Do not ignore the message and continue driving as if nothing happened. The problem will not resolve on its own, and continued driving may cause additional damage to the information system or related components.
Getting a diagnostic scan before you visit a repair shop
A diagnostic scan reads the fault code stored in your vehicle's computer. This code is a specific number that points to which part of the steering system triggered the warning. Without this code, a mechanic is guessing, and guessing costs you money in unnecessary repairs.
You have three options for getting a scan. Many auto parts stores (AutoZone, O'Reilly, NAPA, Advance Auto Parts) will scan your vehicle for free if you ask. You drive to the store, park near the service desk, and a staff member plugs a scanner into the diagnostic port under your steering wheel. The scan takes five minutes and produces a printout with the fault code and a plain-language description of what it means.
If your vehicle is still under warranty, contact your vehicle's dealership and ask for a diagnostic scan. Dealerships have more advanced scanners than parts stores and can often identify problems that generic scanners miss. This usually costs between $100 and $150, but if the vehicle is under warranty, the scan may be free.
Independent repair shops also perform diagnostic scans, usually for $75 to $150. The advantage is that they can often repair the problem the same day if it is straightforward (like a loose battery terminal or low fluid). The disadvantage is that you have to choose a shop before you know what the problem is.
Bring the fault code and the printout from the scan to any repair shop you visit. This prevents the shop from re-scanning and charging you again, and it gives them the information they need to quote you an accurate repair price.
When you can drive with reduced steering information and when you should not
You can drive short distances with reduced steering information — to a repair shop, to a parts store for a diagnostic scan, or to a dealership. The vehicle is still safe to operate. Your steering will be heavier, especially when turning at low speeds or parking, but you have full control.
You should not drive long distances on highways or in heavy traffic with reduced information. The extra effort required to steer for hours is tiring, and if the information system fails completely while you are driving at speed, you will have a much harder time controlling the vehicle. Highway driving also puts more stress on the information system, which may cause the underlying problem to worsen faster.
Do not drive in conditions where you need quick steering responses — heavy rain, snow, or icy roads — with reduced information. These conditions already demand more steering effort, and reduced information makes them significantly harder to manage safely.
If the message appears and then disappears, and then appears again, the problem is intermittent. This is actually more urgent than a constant problem because intermittent faults are harder to diagnose and often indicate a loose connection or a sensor that is failing gradually. Have it scanned as soon as you can.
What repair shops will likely find and what it will cost
The most common repairs are inexpensive. Topping off low power steering fluid costs nothing if you do it yourself, or $20 to $50 if a shop does it. Tightening a loose battery terminal costs $0 to $30. Replacing a blown fuse costs $5 to $15.
More involved repairs cost more. A faulty steering angle sensor replacement typically runs $300 to $600 depending on the vehicle. An electric information motor replacement can range from $400 to $1,200. A power steering pump replacement (in vehicles with hydraulic information) can cost $500 to $1,500.
These are estimates only — actual costs vary significantly by vehicle make and model, your location, and the specific shop. A dealership will charge more than an independent shop for the same repair. A shop in a major city will charge more than a shop in a rural area.
Always get a written estimate before authorizing any repair. The estimate should list the specific part being replaced, the labor hours, and the total cost. If the estimate seems high, you can get a second opinion from another shop — this is normal and expected.
Frequently Asked Questions
Can I drive on the highway with steering information reduced?
You can, but you should not for long distances. Highway driving stresses the information system and makes the underlying problem worse. Drive to a repair shop or dealership, but avoid long trips until the problem is fixed. If you must drive on the highway, stay in the right lane and avoid sudden steering movements.
Will the steering information come back on by itself?
No. The system will not restore full information until the underlying problem is fixed. Restarting the vehicle may temporarily clear the message if it is a sensor glitch, but the message will return. The fault code will remain in the computer until a mechanic clears it after repairing the problem.
Is it safe to drive with reduced steering information in rain or snow?
It is not recommended. Rain and snow already make steering harder, and reduced information makes it significantly harder. If you must drive in these conditions, drive slowly, avoid sharp turns, and stay off highways. Better to wait for better weather or have the vehicle towed to a repair shop.
What if I ignore the message and keep driving?
The information system may fail completely, leaving you with manual steering only. This is dangerous at highway speeds and in parking situations. Ignoring the message also risks damage to other components connected to the information system, which can make repairs more expensive. Address the problem as soon as you can.
Do I need to go to a dealership or can I use an independent shop?
An independent shop can diagnose and repair most steering information problems. Dealerships have more advanced diagnostic tools and may identify problems that independent shops miss, but they charge more. If your vehicle is under warranty, the dealership is your best option because repairs will be covered. Otherwise, an independent shop with good reviews is usually fine.
