Keeping your foot firmly planted on the gas pedal while driving a long distance can be taxing. A cruise control system regulates the engine to keep your automobile moving at a predetermined speed, which reduces driver fatigue when driving long distances.

In order to use a cruise control system, you simply press a button to activate it. Rather than constantly pressing the acceleration pedal, you can take a break while traveling on lengthy distances. Advanced adaptive cruise control employs sensors in the front of the vehicle to keep a safe distance from other vehicles and avoid collisions. A look at the probable causes and treatments for the Subaru cruise control light to flicker.

Additionally, issues with the cruise control system are possible. When it comes to Subaru cars, this problem is extremely prevalent, and the most typical cause is a blinking cruise control light on the dashboard.

Why does a Flashing Cruise Control Light Come In Subaru Cars?

Many technical problems can be indicated by a blinking cruise control light in a Subaru, including engine damage from misfires, a loosened gas cap, or an inoperative speed sensor.

The cruise control light is located on the dashboard instrument panel. In order to tell if the cruise control system is working properly, the light on the dashboard should be white. The cruise control light becomes green when it is activated.

The Possible Causes of Subaru Cruise Control Light Error

There are a number of reasons why Subaru’s cruise control lights may flicker. A few of the most common causes are as follows:

1. Faulty speed sensor

The vehicle’s adaptive cruise control is entirely integrated with the vehicle’s speed sensor. When the car’s computer receives information from the speed sensors, it sends that information to the car’s engine and transmission.

If the vehicle’s speed sensors malfunction, the computer will be unable to determine the vehicle’s speed and so the cruise control will not work.

Because a faulty speed sensor might potentially affect the vehicle’s speedometer, it’s important to have it repaired as soon as possible.

2. Blown fuse

There are fuses in the cruise control system to protect the electrical system. The cruise control system will be disabled unless you replace the blown fuse. In the event of an electrical problem, the fuse will blow in order to protect the other wiring system from damage.

Replace the fuse and see if that stops the blinking of the cruise control lights. However, if the fuse blows again, you’ll need the help of a professional mechanic to diagnose the problem.

3. Failing brake pedal switch

When you push the brake pedal, the brake lights come on perfectly. The brake pedal switch is to blame. Breakdowns in the brake pedal switch can result in problems with the cruise control as well as the brake lights.

Using the brakes when using cruise control causes the system to shut down and the car to return to manual control. To activate cruise control, the vehicle has to know that you’ve stepped on the brake pedal. If the brake pedal switch is defective, this is not possible.

4. Faulty mechanical components

When the cruise control light is flashing on an older Subaru model, there is a good chance that the problem is mechanical. Using a vacuum actuator and cable to link the throttle, the mechanical cruise control system keeps the cable in sync with the cruise control settings.

The cruise control may not work properly if one of the mechanical components is broken.

Is It Safe To Drive With Cruise Control Light Flashing?

It is safe to continue driving your vehicle even if your cruise control light begins to flash, as long as you do not use the cruise system.

It is simply the cruise control system that is affected when a problem is found. Some flaws, on the other hand, can occasionally cause issues with other driving systems.

For example, if your brake switch fails, you won’t be able to turn on your brake lights to warn other drivers behind you when you use the brakes, increasing the risk of an accident. It’s always a good idea to get your car checked out to make sure nothing is wrong and to make sure you’re not putting yourself in danger.


Your car may have a problem if the cruise control light is flashing. You should not use the cruise control until it has been repaired if it is not working properly.

You can try to solve the problem yourself, but the best and most convenient approach for most novices is to contact a Subaru dealership service center.
