- "Service Power Steering" warning
- Transmission surging or shifting issues
- Loss of power steering assistance
- Issues worse in freezing temperatures
How to Fix

NHTSA campaign 26V363000 covers certain 2021-2025 Jeep Wrangler, Wrangler 4xe and Gladiator vehicles. High resistance at the electric-hydraulic power steering pump electrical connection may overheat combustible material and cause a vehicle fire, including while the vehicle is parked with the ignition off. Loss of steering assist or a Service Power Steering message may occur.
Common Symptoms
- Loss of power steering assist
- Service Power Steering message
- Electrical overheating or fire
How to Fix
Check the VIN for campaign 26V363000 (FCA recall 21D). Until repaired, park outside and away from structures and other vehicles. Dealers inspect and repair or replace affected wiring and the electric-hydraulic power steering pump as necessary, free of charge.

The Grand Wagoneer's electric power steering (EPS) rack-and-pinion assembly experiences premature failure, manifesting as sudden loss of power steering assist, wandering on the highway, or excessive steering effort. The EPS motor or internal torque sensor fails, triggering a steering warning light. Given the Grand Wagoneer's 6,000+ lb curb weight, loss of power steering assist makes the vehicle extremely difficult to control, especially at low speeds. Stellantis issued recall 23V-635 for certain VINs related to steering rack fastener torque, but the EPS motor failure is a separate concern.
Common Symptoms
- Steering assist warning light illuminated
- Sudden heavy steering effort
- Steering wanders or drifts at highway speed
- Steering feels loose or disconnected in center position
- Clunking from steering rack area during turns
How to Fix
The EPS rack must be replaced as a complete assembly — the internal motor and torque sensor are not serviceable separately. Dealer replacement under warranty (5-year/60,000-mile basic warranty covers steering). After replacement, a steering angle sensor calibration and alignment must be performed. If out of warranty, remanufactured EPS racks from certified rebuilders are available at 40-50% savings over new OEM. Verify recall 23V-635 compliance at the same time.

Owner tips & cautions
- WarningIf your Grand Wagoneer steering warning light comes on, do NOT continue driving. This 6,000+ lb vehicle is nearly impossible to steer without power assist at parking lot speeds. Pull over safely and call for a tow to the dealer. This is a safety-critical failure.

Frequently asked questions
What does U0131 mean on a Jeep?
U0131 stands for "Lost Communication with Power Steering Module." This is a network communication code meaning the vehicle's computers have lost communication with the power steering control module over the data bus (CAN). Modern cars link control modules so they can share data, and this code sets when other modules stop receiving expected messages from the power steering unit. The most common result is loss or reduction of power-assisted steering, making the wheel feel heavy, along with a warning light. It generally points to a wiring/connector or power problem at the steering module, a bus fault, or a failed module rather than a mechanical steering issue. On Jeep it is documented across 3 models: Cherokee, Wrangler, Grand Wagoneer.
What are the most common causes of U0131?
The most common causes of U0131 are: Loss of power or ground to the power steering module, Open or shorted CAN bus wiring to the module, Corroded or loose connector at the steering module, Blown fuse feeding the power steering system, Failed power steering control module, Other module or wiring fault disrupting the data bus, Software/configuration mismatch after a repair. The specific cause varies by vehicle.
How much does it cost to fix U0131 on a Jeep?
Published repair estimates on Jeep range from $150 to $3,500 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
