2012 Subaru Forester Cruise Control Isn't Working

When troubleshooting a non-functioning cruise control in a 2012 Subaru Forester, it's essential to adopt a systematic diagnostic approach that begins with the simplest solutions before progressing to more complex issues. Start by checking the cruise control fuse, as a blown fuse can easily disrupt the system's functionality. Next, inspect the brake pedal switch, which is crucial for the cruise control operation; if this switch is faulty, it may prevent the cruise control from engaging. Following this, examine the speed sensor, as any malfunction here can affect both the cruise control and the speedometer. Additionally, verify the integrity of the electrical wiring associated with the cruise control system, as damaged wires can lead to operational failures. Pay attention to any warning lights on the dashboard, such as the check engine light, which may indicate broader issues that could impact the cruise control. Lastly, ensure that the cruise control main switch and the SET/COAST switch are functioning correctly, and if your Forester is equipped with Subaru EyeSight® or adaptive cruise control, check that these systems are properly calibrated. By methodically addressing these areas, you can effectively diagnose and potentially resolve the cruise control issue. If problems persist, seeking assistance from a qualified Subaru technician is advisable for a thorough evaluation.

When dealing with cruise control issues in a 2012 Subaru Forester, several common problems may be at play. A blown fuse is often the first culprit to check, as it protects the system from electrical faults. If the fuse is intact, the next step is to inspect the speed sensor, which is vital for relaying speed data to the cruise control system; a malfunction here can also affect the speedometer. Additionally, the brake pedal switch should be examined, as a failure can lead the system to mistakenly believe the brakes are engaged, preventing cruise control activation. Electrical or wiring issues can also disrupt functionality, particularly connections related to the brake pedal switch. For those with older models, while less likely in a 2012, it's worth noting that vacuum actuators and hoses can cause problems in systems that rely on them. Furthermore, if the check engine light is illuminated, it may disable the cruise control due to various underlying issues, so reading trouble codes is essential. Lastly, if your Forester is equipped with EyeSight® or adaptive cruise control, calibration or electronic system problems may require professional attention. By systematically checking these components, DIYers can effectively diagnose and potentially resolve cruise control issues.

While a non-functioning cruise control in a 2012 Subaru Forester may not pose an immediate safety risk, it is crucial to recognize the urgency of addressing this issue. Ignoring the malfunction can lead to increased driver fatigue during long trips, diminishing the overall comfort and convenience that cruise control provides. More importantly, the failure of this feature could be indicative of underlying problems, such as electrical or sensor issues that may affect other critical systems in the vehicle. For instance, a malfunctioning speed sensor or brake pedal switch could not only disable the cruise control but also compromise the functionality of the speedometer or brake lights, potentially leading to hazardous driving conditions. Additionally, neglecting to investigate the root cause could result in more severe damage over time, as components that are failing may impact multiple systems within the vehicle. Therefore, it is advisable to promptly diagnose and address the issue to ensure the reliability and safety of your Subaru Forester, preventing minor inconveniences from escalating into significant repairs.
