What is the reason why the Subaru cruise keeps flashing and cannot be turned off?

This is a prompt indicating that the user accidentally pressed the cruise control button, and it can be turned off. Introduction to Cruise Control: The cruise control system is an electronic control technology that maintains the vehicle's automatic constant speed. Its main function is to lock the vehicle's speed as required by the driver, allowing the vehicle to maintain a fixed speed without pressing the accelerator pedal. When driving on highways, the driver can effectively reduce physical fatigue, and the constant speed also helps save fuel consumption. Conditions for Using Cruise Control: The cruise control system is not suitable for all times and places. Professionals suggest that cruise control should, in principle, be used on highways or fully enclosed roads. This is because on non-enclosed roads, complex road conditions are not conducive to traffic safety.
Having driven a Subaru for over a decade, I've encountered the strange issue where the cruise control light keeps flashing and won't turn off. Most likely, it's a problem with the brake light switch. This switch is responsible for telling the system whether you're pressing the brake or not. If it's faulty, the system gets confused and thinks the brake is being applied, triggering the flashing warning light that won't turn off. Secondly, it could also be due to a dirty or loose speed sensor, causing inaccurate wheel speed readings at high speeds. Another possibility is an issue with the electronic control module, moisture causing a short circuit in the wiring, or even the safety system itself making a false judgment. It's best to try restarting the car first: turn it off, wait a few minutes, and then start it again. Sometimes minor software glitches can resolve themselves. Checking if the brake lights are working is quick too: have someone press the brake while you check the rear lights; if they don't light up, replace the switch immediately. Otherwise, driving with a malfunctioning cruise control system at high speeds poses a significant risk. Don't delay—take it to a professional repair shop right away, as Subaru's systems are quite sensitive.
