The most common reasons a 2007 Subaru Legacy cruise control isn't working are failed control module, sensor or switch issues, or throttle actuation problems.

Sensor: A faulty sensor can lead to incorrect readings, causing issues with engine performance or triggering warning lights on the dashboard.
Control Module: A faulty control module can result in erratic vehicle behavior or failure of various electronic systems due to improper signal processing.
Throttle: A faulty throttle body or a defective accelerator pedal position sensor may be causing inconsistent acceleration and poor engine response.

How urgent is it to address the non-functioning cruise control in a 2007 Subaru Legacy?

Addressing the non-functioning cruise control in a 2007 Subaru Legacy is crucial for both safety and vehicle performance. The flashing cruise control light serves as a warning that there may be underlying mechanical or electrical issues that could compromise your driving experience. Ignoring these symptoms can lead to more severe problems, such as increased fuel consumption or even engine complications, particularly if the throttle position sensor is affected. Additionally, a malfunctioning cruise control system can detract from the convenience it offers during long drives, making it less enjoyable and more tiring. While it may not seem like an immediate emergency, timely repairs are essential to prevent further damage and ensure that your vehicle operates smoothly. By addressing the issue promptly, you not only enhance your safety on the road but also maintain the functionality of your Subaru Legacy, allowing you to enjoy the benefits of cruise control when you need it most.
