Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
Hyundai Veloster · 2019–2021
Multiple owners reported sudden loss of steering assist or abnormally heavy steering effort, sometimes accompanied by warning lights and fault messages. On modern Hyundai platforms this is commonly tied to the Motor Driven Power Steering (MDPS) system, steering angle/torque sensing, or column-related electrical faults. Even when the vehicle remains steerable, the abrupt increase in effort creates a meaningful safety concern at low speeds and during evasive maneuvers.
Common Symptoms
- sudden heavy steering
- loss of power steering assist
- EPS or steering warning light
- steering effort changes while driving
- warning chime or message on cluster
How to Fix
Perform a full scan of EPS/MDPS modules, inspect battery voltage and charging stability, and check steering column connectors and torque/angle sensor data. Depending on findings, repairs may involve software updates, steering column or MDPS component replacement, and steering angle calibration. Intermittent failures should be documented with freeze-frame data because some vehicles behave normally once restarted.

Frequently asked questions
What does C2402 mean?
C2402 stands for "TPMS Transmitter ID Not Received / Receiver Fault (Manufacturer-Specific)." C2402 is a manufacturer-specific chassis code (common on Toyota/Lexus) in the Tire Pressure Monitoring System family, generally indicating that a specific tire pressure transmitter ID was not received or that there is a TPMS receiver/initialization fault. The TPMS ECU expects a unique ID signal from each wheel sensor; when one is missing or unregistered, the code sets. The TPMS warning light typically illuminates and affected tire pressures may not display. This is an advisory/safety code; check tire pressures manually.
What are the most common causes of C2402?
The most common causes of C2402 are: TPMS sensor ID not registered/initialized, Weak or dead TPMS sensor battery, Faulty or missing tire pressure sensor, Receiver, antenna, or wiring fault, Radio-frequency interference, TPMS control module fault. The specific cause varies by vehicle.
How much does it cost to fix C2402?
