Troubleshooting Steps for Subaru Forester Push Button Start Issues

Experiencing issues with the push button start feature in a Subaru Forester can be frustrating, especially when you rely on this convenient technology for your daily driving needs. Fortunately, there are several troubleshooting steps you can take to identify and potentially resolve the problem. First and foremost, it is essential to ensure that the key fob is functioning correctly. A common issue that can prevent the push button start from working is a dead or weak battery in the key fob. To address this, you can try replacing the battery in the key fob, which is typically a simple process. Most key fobs can be opened with a small screwdriver, allowing you to access the battery compartment easily. After replacing the battery, attempt to start the vehicle again to see if the issue persists.

If the key fob battery replacement does not resolve the problem, the next step is to check the vehicle’s battery. A weak or dead car battery can also prevent the push button start from functioning. To assess the condition of the battery, you can use a multimeter to measure the voltage. A healthy car battery should read around 12.6 volts or higher when the engine is off. If the voltage is significantly lower, it may be time to jump-start the vehicle or replace the battery altogether. Additionally, ensure that the battery terminals are clean and securely connected, as corrosion or loose connections can impede electrical flow.

In some cases, the issue may lie within the push button start system itself. If you hear a clicking sound when pressing the start button, this could indicate a problem with the starter motor or the ignition system.
