Why is my Subaru Legacy cruise control not working?

Possible Reasons for Subaru Legacy Cruise Control Not Working
There are several potential reasons why your Subaru Legacy’s cruise control may not be working:
1. Dirty or Blocked Cameras: If your vehicle is equipped with Subaru EyeSight, the cruise control system may use cameras to sense the location of other cars in front of you. If these cameras are dirty, blocked, or not functioning properly, the adaptive cruise control may not work as it should.
2. Brake Switch: The cruise control system is designed to turn off immediately when the brake is pressed. A faulty brake switch could potentially cause the cruise control to disengage unexpectedly.
3. Seatbelt Status: In some cases, the cruise control may not function if the seatbelt is not buckled. It’s important to ensure that the seatbelt is properly buckled before attempting to use the cruise control.
4. Mechanical or Electrical Issues: There could be mechanical or electrical issues within the cruise control system itself, such as a faulty control module, sensor, or throttle.
5. Drive-By-Wire System: In some cases, problems with the drive-by-wire system can affect the functionality of the cruise control.
It’s important to have a mechanic check the cruise control system to determine the nature of the problem and address any potential safety concerns.
If you’re experiencing any additional symptoms, such as unusual noises or warning lights, it’s advisable to have those issues inspected as well, as they may be related to the cruise control problem.
