Subaru Impreza check engine, skid, and cruise lights issue with potential catalytic converter failure on Subaru Impreza

Some Subaru Impreza owners report experiencing warning lights, such as the check engine, skid, and cruise control lights, which may indicate various issues, including potential catalytic converter failure. These lights can illuminate when the on-board diagnostic system detects problems with the engine or emissions system, and a blinking check engine light often signifies a major issue like engine misfiring that requires immediate attention. Additionally, the cruise control and traction control lights may activate as a response to the check engine light being on. While some owners attempt to reset these warning lights by disconnecting the battery and discharging the system, it is crucial to address the underlying issues causing them. Furthermore, it is common for the cruise control to deactivate when the check engine light is illuminated as a safety precaution. Problems with sensors, such as the rear O2 sensor, can also affect the data sent to the Engine Control Module (ECM), potentially triggering these warning lights. Therefore, it is advisable for owners experiencing these symptoms to have their Subaru Impreza inspected by a mechanic to diagnose the specific issue and prevent further damage or costly repairs.
