Subaru Forester Remote Start Not Working? Troubleshooting Guide & Fixes

The Subaru Forester is a popular compact SUV known for its reliability and versatility. However, some owners may encounter issues with the remote start feature not functioning as expected. This problem can stem from various factors, including key fob battery depletion, vehicle settings, or potential malfunctions in the remote start system itself. Understanding the common causes and troubleshooting steps can help Forester owners resolve these issues and restore the convenience of remote starting their vehicle.

Common Reasons Why Subaru Forester Remote Start Fails

The Subaru Forester is a popular compact SUV known for its reliability and versatility, and one of its convenient features is the remote start system. However, there are instances when this feature may fail to operate as intended, leaving owners frustrated. Understanding the common reasons behind remote start failures can help diagnose the issue and restore functionality.

One of the primary reasons the remote start may not work is related to the vehicle’s battery. A weak or dead battery can prevent the remote start system from functioning properly. If the battery is low on charge, it may not have enough power to engage the remote start feature. Therefore, it is advisable to check the battery’s condition and ensure it is fully charged. Additionally, if the battery terminals are corroded or loose, this can also impede the electrical connection necessary for the remote start to operate.

Another common issue is the key fob itself. The remote start feature is typically activated through a key fob, and if the fob’s battery is depleted, it will not send the signal required to start the vehicle remotely. Replacing the battery in the key fob is a simple and often overlooked solution. Furthermore, if the key fob is damaged or malfunctioning, it may need to be reprogrammed or replaced entirely. Ensuring that the key fob is in good working condition is essential for the remote start feature to function effectively.

In addition to battery and key fob issues, environmental factors can also play a significant role in remote start failures. For instance, if the vehicle is parked in an area with extreme temperatures, either hot or cold, the remote start may not engage. Subaru vehicles are designed with safety features that prevent remote start activation under certain conditions, such as when the engine is already running or if the vehicle is in gear. Therefore, it is important to ensure that the vehicle is in a suitable environment for remote starting.

Moreover, the vehicle’s security system can interfere with the remote start function. If the security system is triggered or if there are issues with the immobilizer, the remote start may not work. In such cases, it may be necessary to reset the security system or consult the owner’s manual for troubleshooting steps. Additionally, if the vehicle has been involved in an accident or has undergone modifications, these changes could affect the remote start system’s functionality.

Lastly, software glitches or malfunctions within the vehicle’s onboard computer can also lead to remote start failures. Just like any other electronic system, the remote start feature relies on software to operate correctly. If there are updates available for the vehicle’s software, installing them may resolve any issues related to remote start functionality. In some cases, a visit to a certified Subaru dealership may be required to diagnose and rectify more complex software-related problems.

In conclusion, while the remote start feature in the Subaru Forester is a valuable convenience, various factors can contribute to its failure. By systematically checking the battery, key fob, environmental conditions, security system, and software updates, owners can identify and address the underlying issues. Understanding these common reasons can empower Subaru Forester owners to troubleshoot effectively and restore their remote start functionality, enhancing their overall driving experience.

Troubleshooting Tips for Subaru Forester Remote Start Issues

Experiencing issues with the remote start feature of your Subaru Forester can be frustrating, especially when you rely on it for convenience and comfort. Fortunately, there are several troubleshooting tips that can help you identify and resolve the problem. First and foremost, it is essential to ensure that your vehicle’s battery is in good condition. A weak or dead battery can prevent the remote start system from functioning properly. Therefore, checking the battery voltage and connections is a prudent first step. If the battery is low, consider jump-starting the vehicle or replacing the battery altogether.

In addition to the battery, it is crucial to examine the key fob itself. Sometimes, the issue may stem from a depleted battery in the key fob, which can hinder its ability to communicate with the vehicle. Replacing the battery in the key fob is a simple process that can often resolve the issue. After replacing the battery, test the remote start function again to see if it works as intended. If the problem persists, it may be beneficial to reprogram the key fob. This can typically be done by following the instructions in the owner’s manual or consulting with a Subaru dealership for assistance.

Another common cause of remote start issues is the vehicle’s security system. If the security system is triggered or malfunctioning, it may prevent the remote start feature from activating. To troubleshoot this, check for any warning lights on the dashboard that may indicate a security system issue. If you suspect that the security system is the culprit, resetting it may resolve the problem. This can often be done by locking and unlocking the doors using the key fob or by using the physical key to unlock the driver’s door.

Moreover, environmental factors can also play a role in the functionality of the remote start system. For instance, extreme temperatures, whether hot or cold, can affect the performance of electronic components. If you are attempting to use the remote start feature in very cold weather, ensure that the vehicle is equipped with the necessary winterization features, such as a block heater, which can help the engine start more easily. Conversely, in hot weather, ensure that the vehicle is parked in a shaded area to prevent overheating, which can also impact the remote start functionality.

Furthermore, it is essential to verify that the remote start feature is enabled in the vehicle’s settings. Some Subaru Forester models allow owners to customize various features, including remote start. If the feature has been inadvertently disabled, it will not function as expected. Consulting the owner’s manual for guidance on accessing and adjusting these settings can be beneficial.

If, after following these troubleshooting tips, the remote start feature still does not work, it may be time to seek professional assistance. A certified Subaru technician can perform a thorough diagnostic to identify any underlying issues that may not be immediately apparent. They can also check for software updates or recalls that may affect the remote start system. In conclusion, while remote start issues can be inconvenient, a systematic approach to troubleshooting can often lead to a resolution, allowing you to enjoy the convenience of your Subaru Forester once again.

How to Reset Your Subaru Forester Remote Start System

If you find that the remote start feature of your Subaru Forester is not functioning as expected, it can be both frustrating and inconvenient. Fortunately, there are several steps you can take to reset the remote start system, which may resolve the issue and restore its functionality.

If the remote start system still does not work after these initial steps, it may be necessary to check the vehicle’s settings. Some Subaru Forester models have specific settings that can disable the remote start feature. To access these settings, refer to your owner’s manual for guidance on navigating the vehicle’s menu system. Look for options related to remote start or vehicle security, and ensure that the feature is enabled. Adjusting these settings may restore the remote start functionality.

Additionally, it is worth considering whether any recent changes or updates to your vehicle’s software could be impacting the remote start system. Subaru occasionally releases software updates that can enhance vehicle performance and features. If you suspect that a software update may be necessary, visit your local Subaru dealership or authorized service center.
