2017 Subaru Forester Speedometer Isn't Working

To effectively diagnose a non-functioning speedometer in your 2017 Subaru Forester, begin with the simplest solutions. Start by checking the fuse associated with the speedometer in the fuse box, as a blown fuse is a common and easily fixable issue. If the fuse is intact, move on to inspecting the speed sensor located on the transmission; ensure it is not damaged or disconnected, as this component is crucial for relaying speed data. Next, examine the wiring connections for any signs of looseness, damage, or corrosion, which can disrupt the signal to the speedometer. If these preliminary checks do not resolve the issue, utilize an OBD-II scanner to scan for error codes that may indicate specific problems with the speedometer or vehicle speed sensor. Finally, if all else fails, consider testing the speedometer cluster itself for internal faults. By following this structured diagnostic approach, you can efficiently identify and address the root cause of your speedometer malfunction.

When troubleshooting a malfunctioning speedometer in a 2017 Subaru Forester, it's essential to consider several common problems that could be affecting its performance. One of the primary culprits is a faulty vehicle speed sensor, which plays a crucial role in relaying speed information to the speedometer. If this sensor is malfunctioning, it can result in inaccurate readings. Additionally, inspect the wiring connected to the speedometer, as damaged or loose connections can disrupt the signal and lead to erratic behavior. Another area to examine is the instrument cluster itself; issues such as faulty gauges or internal circuitry problems can also cause the speedometer to fail. In some cases, the speedometer head may be defective, preventing it from displaying the correct speed. Lastly, consider the vehicle's computer system, as any glitches or errors in communication with the speedometer can contribute to the malfunction. By systematically checking these components, DIYers can effectively diagnose and potentially resolve the speedometer issues in their Subaru Forester.

Addressing a non-functioning speedometer in your 2017 Subaru Forester is not just a matter of convenience; it is an urgent necessity. A malfunctioning speedometer can lead to serious legal repercussions, as driving without accurate speed readings may result in unintentional speeding, fines, or even license suspension. Beyond legal issues, safety is a paramount concern; without a functioning speedometer, you may struggle to maintain appropriate speeds, increasing the risk of accidents, especially in varying road conditions. Additionally, the speedometer is linked to other critical vehicle systems, and its failure could signal deeper mechanical problems that may compromise your vehicle's overall performance. Lastly, if you plan to sell your Forester in the future, a non-functioning speedometer can significantly diminish its resale value, as potential buyers are often wary of unresolved mechanical issues. Therefore, it is crucial to address this problem promptly to ensure your safety, comply with legal standards, and protect your investment.
