2016 Subaru Impreza Cruise Control Isn't Working

To effectively diagnose the non-functioning cruise control in your 2016 Subaru Impreza, start with a systematic approach that prioritizes simpler solutions before delving into more complex diagnostics. Begin by checking for any error codes or warning lights on your dashboard, as these can indicate underlying issues that may disable the cruise control. Utilize an OBD-II scanner to retrieve error codes, which can guide you in identifying the root cause. Next, inspect basic connections and components, ensuring that the gas cap is securely closed, as a loose cap can trigger error codes. Disconnecting the negative battery cable for a few minutes may also help reset the system. Proceed to check the relevant fuses associated with the cruise control system, as a blown fuse can interrupt functionality. Examine the cruise control stalk for proper operation, and if necessary, test it with a multimeter or replace it. The brake switch is another critical component; ensure it is functioning correctly, as it must work in tandem with the cruise control system. Additionally, inspect the clock spring or roll connector, especially if other systems like the horn are affected. Look for any damaged wiring that could be causing the issue. If the cruise control light is flashing without a check engine light, consider resetting the system by removing the key and opening the driver's door. If these steps do not resolve the problem, it may be time to consult a professional mechanic for a thorough diagnosis. By following this structured approach, you can efficiently troubleshoot and potentially fix the cruise control issue in your Subaru Impreza.

When dealing with cruise control issues in a 2016 Subaru Impreza, it's essential to consider several common problems that could be at play. Start by inspecting the cruise control fuse located in the fuse box; a blown fuse is a straightforward fix that can restore functionality. Next, examine the brake pedal switch, as a malfunction here can inadvertently disengage the cruise control when the brake is pressed. If the speedometer is also acting erratically, the speed sensor may be faulty, impacting the cruise control's performance. Additionally, issues within the steering column, such as a defective steering switch or loose connections, can lead to intermittent cruise control operation. Don't overlook potential wiring and electrical problems, as damaged connectors or wiring harnesses can disrupt the system. For vehicles equipped with Subaru EyeSight® or adaptive cruise control, ensure that the system is properly calibrated, especially after windshield replacements. Lastly, check other safety switches and sensors, as faults in these components can also cause unexpected disengagement. By systematically checking these areas, you can effectively diagnose and potentially resolve cruise control issues in your Subaru Impreza.

While a malfunctioning cruise control system in your 2016 Subaru Impreza may not pose an immediate safety risk, it is still important to address the issue in a timely manner. Ignoring the problem can lead to increased driver fatigue during long trips, as the convenience of cruise control is lost. Additionally, if the malfunction is linked to underlying issues, such as a faulty brake pedal switch or electrical problems, neglecting these symptoms could result in more significant repairs down the line. Therefore, while you can safely drive your vehicle without cruise control, it is advisable to perform basic diagnostic checks and seek professional assistance if necessary. This proactive approach not only enhances your driving comfort but also helps prevent potential complications that could arise from unresolved issues.
