Jeep Grand Wagoneer · 2022–2024
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.
