C2101 on Jeep by model: symptoms, diagnosis and fix
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 C2101 mean on a Jeep?
C2101 stands for "TPMS Receiver / Transmitter Reception Fault (Manufacturer-Specific)." C2101 is a manufacturer-specific chassis code (common on Toyota/Lexus) within the Tire Pressure Monitoring System family. It generally indicates the TPMS receiver/ECU did not properly receive an expected signal from one or more wheel-mounted tire pressure transmitters, or that a receiver-side reception fault occurred. The TPMS warning light typically comes on and live tire pressures may not display. It is a comfort/safety-advisory code rather than a drivability fault, but tire pressures should still be checked manually. On Jeep it is documented across 1 model: Grand Wagoneer.
What are the most common causes of C2101?
The most common causes of C2101 are: Weak or dead TPMS sensor (transmitter) battery, TPMS sensor IDs not registered to the receiver, Faulty TPMS receiver/antenna or wiring, Radio-frequency interference blocking the signal, Damaged or missing tire pressure sensor, Failed TPMS control module. The specific cause varies by vehicle.
