U3000 on Hyundai
Control Module
U3000 on Hyundai vehicles indicates control module. Au7o has documented this code across 1 Hyundai model — most commonly on Veloster. U3000 is a generic network code indicating a control module has detected an internal fault within itself or a related controller, or a problem in the module/CAN wiring system. It is often accompanied by a sub-fault letter or number that narrows down whether the issue is internal electronics, calibration, or a communication/voltage problem. In practice it means a module is reporting that it (or a module it monitors) is not functioning correctly, which can put the system into a protective/safe mode. Typical repair costs on Hyundai range from $200 to $1,800, depending on the specific model and root cause.
Common Causes of U3000
- •Internal failure of a control module (ECU/controller)
- •Corroded or damaged module wiring/connectors
- •Poor power or ground supply to the module
- •Moisture intrusion into a module
- •Software/calibration error or needed reflash
- •CAN/communication bus fault affecting the module

- Forward Collision-Avoidance / Driver Assistance False Warnings and Camera-Radar Malfunctions2019-2021
Owners have documented intermittent failures of the forward collision warning, lane-keeping, and related ADAS functions, including dashboard messages that the front camera or safety systems are unavailable. Some complaints involve false alerts in clear weather, while others describe the systems disabling themselves after startup or while driving. These issues are often linked to camera alignment, sensor contamination, software logic, or wiring/connectivity problems rather than a mechanical brake fault.
