Service Power Steering warning causes in Jeep

Jeep owners often experience a sense of pride and adventure as they navigate challenging terrains and conquer the great outdoors. However, even the most robust vehicles can sometimes encounter unexpected issues. One such concern that can leave Jeep drivers perplexed is the appearance of the dreaded “Service Power Steering” or ” warning. When this warning light illuminates on the dashboard, it raises questions about the safety and functionality of the power steering system.

The Service Power Steering warning in Jeeps can be attributed to various causes, ranging from minor issues to more significant mechanical failures.

Low Power Steering Fluid

Insufficient power steering fluid is one of the primary culprits behind the warning light. If the fluid level is below the recommended range, it can cause the power steering system to malfunction, leading to the warning light activation. Regularly checking the power steering fluid level and ensuring it is at the appropriate level can help prevent this issue.

Faulty Power Steering Pump

The power steering pump is responsible for generating hydraulic pressure, assisting in steering wheel movement. If the pump becomes worn out or develops a fault, it can result in a loss of power steering assistance and trigger the warning light. A malfunctioning power steering pump may require repair or replacement.

Electrical or Sensor Issues

In some instances, electrical problems or sensor malfunctions can cause the Service Power Steering warning to appear. Faulty sensors that monitor the power steering system may send incorrect signals to the vehicle’s computer, leading to the warning light activation. Diagnosing and rectifying these electrical or sensor-related issues typically requires professional assistance.

Steering Gear Problems

The steering gear, also known as the rack and pinion, is responsible for converting the rotational motion of the steering wheel into lateral movement of the wheels. Issues such as leaks, excessive wear, or damage to the steering gear assembly can affect the power steering system’s performance and trigger the warning light.

Wiring or Connection Faults

Loose or damaged wiring connections within the power steering system can disrupt the flow of electrical signals, resulting in the Service Power Steering warning. These faults can occur due to wear and tear, vibrations, or accidents. Inspecting the wiring and connections for any signs of damage and addressing them promptly can help resolve the issue.

Faulty control module

A faulty control module is another potential cause of the Service Power Steering warning in Jeeps. The control module is a vital component that manages and regulates various aspects of the power steering system, including sensor inputs and hydraulic pressure.

If the control module malfunctions or becomes damaged, it can disrupt the normal functioning of the power steering system, leading to the warning light activation. This can occur due to electrical issues, software glitches, or physical damage to the module.

Diagnosing a bad control module typically requires specialized diagnostic equipment to retrieve error codes and perform thorough testing. A professional technician with expertise in Jeep vehicles can assess the control module’s condition and determine if it needs repair or replacement.

It’s worth noting that a bad control module may exhibit additional symptoms besides the Service Power Steering warning. These can include erratic steering response, difficulty in turning the wheel, or complete loss of power steering assistance. If you experience any of these issues along with the warning light, it is essential to address the problem promptly to ensure safe driving conditions.

Replacing a faulty control module is a task that is best left to trained professionals. They have the knowledge and tools necessary to properly diagnose the issue and carry out the required repairs or replacements.

Grand Cherokee steering column recall

Fiat Chrysler US has issued a recall for 89,327 units of the Jeep Grand Cherokee manufactured between 2021 and 2023. These vehicles may have been built with incorrectly assembled intermediate shafts in their steering columns. This assembly issue could result in the intermediate shaft disconnecting from the U-joint that connects it to the column. Consequently, drivers may experience a loss of steering control, potentially leading to accidents. The automaker assures that there have been no reported crashes or injuries associated with this problem.

The cause of the issue is not defective parts but rather improper repairs performed during the assembly process of the affected Grand Cherokees. The Safety Recall Report submitted to the National Highway Traffic Safety Administration (NHTSA) reveals that the fault lies in the repair procedures conducted on the assembly line. Jeep Grand Cherokee L models, totaling 35,407 units produced between January 27, 2021, and April 4, 2023, are included in the recall. Additionally, 59,935 units of the regular Jeep Grand Cherokee manufactured from October 19, 2021, to April 4, 2023, are affected. Jeep implemented revised repair instructions on April 4 to address and prevent this issue from occurring.

To rectify the problem, owners will need to visit an authorized dealer for a steering column inspection. If necessary, the dealership will replace the intermediate shaft and associated hardware, ensuring correct installation.

FCA US plans to commence mailing notification letters on July 7, 2023, informing owners about the recall. In the meantime, concerned owners can contact FCA US customer service at 800-853-1403, referring to the internal recall number 58A. They may also reach out to the NHTSA Vehicle Safety Hotline at 888-327-4236 (TTY 800-424-9153), or visit, and reference campaign number 23V352000 for additional information.

Scan for diagnostic trouble codes

When faced with a Service Power Steering warning in your Jeep, one of the first steps you can take is to scan the vehicle’s onboard diagnostics (OBD) system using an OBD scanner. This tool allows you to retrieve error codes stored in the vehicle’s computer system, providing valuable information about the specific issue triggering the warning light.

Acquire an OBD scanner

OBD scanners come in various forms, ranging from handheld devices to smartphone apps. Ensure that the scanner you choose is compatible with your Jeep’s OBD system. Most scanners will have a universal OBD-II connector, which is standard in vehicles manufactured from 1996 onwards.

Locate the OBD port

The OBD port is typically found underneath the dashboard on the driver’s side. It may be covered by a small panel that can be easily removed. Consult your vehicle’s owner’s manual or look for the OBD port diagram online to locate it accurately.

Connect the OBD scanner

Plug the OBD scanner’s connector into the OBD port of your Jeep. Ensure that the connection is secure.

Turn on the ignition

Switch on the ignition without starting the engine. This will power up the vehicle’s systems and enable communication between the OBD scanner and the Jeep’s computer.

Scan for error codes

Follow the instructions specific to your OBD scanner to initiate the scanning process. This usually involves navigating through menu options on the scanner’s display or within the smartphone app. Select the appropriate scan mode (e.g., “Read Codes” or “Scan for Codes”) to begin the scan.

Interpret the error codes

Once the scan is complete, the OBD scanner will display the retrieved error codes. These codes are alphanumeric and correspond to specific issues within the vehicle. Refer to the scanner’s manual or search online for a list of OBD codes specific to your Jeep model to interpret the meaning of each code.

Scanning the OBD system with an OBD scanner allows you to gather valuable diagnostic information, enabling you to take appropriate actions to address the Service Power Steering warning in your Jeep. Remember to consult the scanner’s manual or seek professional advice to fully understand the error codes and determine the necessary steps to resolve the underlying issue.

Seek professional assistance

It is essential to note that the specific cause of the Service Power Steering warning can vary depending on the Jeep model and year.

When confronted with this warning light, it is recommended to consult the vehicle’s owner’s manual for model-specific information and seek professional assistance from qualified mechanics or authorized Jeep service centers.
