Subaru Ascent Remote Start Not Working? Easy Solutions

Introduction

The Subaru Ascent is equipped with a convenient remote start feature that allows drivers to start their vehicle from a distance, providing comfort and convenience, especially in extreme weather conditions. However, there are instances when the remote start may not function as intended. This issue can stem from various factors, including battery problems, key fob malfunctions, or system settings. Understanding the potential causes and troubleshooting steps can help owners resolve the issue and restore the functionality of their remote start system.

Common Reasons Why Subaru Ascent Remote Start Fails

The Subaru Ascent is a popular choice among families and adventure seekers alike, offering a blend of comfort, space, and advanced technology. One of the appealing features of the Ascent is its remote start capability, which allows drivers to start their vehicle from a distance, ensuring a comfortable cabin temperature before entering. However, there are instances when this feature may fail to operate as intended. Understanding the common reasons behind remote start failures can help owners troubleshoot the issue effectively.

One of the primary reasons for remote start malfunction is the vehicle’s security system. The Subaru Ascent is equipped with a sophisticated security system designed to prevent unauthorized access. If the system detects any irregularities, such as an open door or a malfunctioning key fob, it may disable the remote start feature. Therefore, it is essential to ensure that all doors, including the trunk and hood, are securely closed before attempting to use the remote start function. Additionally, if the key fob battery is low or depleted, it may not communicate effectively with the vehicle, leading to a failure in initiating the remote start.

In addition to battery-related issues, the vehicle’s engine status plays a crucial role in the remote start process. The Subaru Ascent is designed to prevent remote starting if the engine is already running or if it has detected any faults within the engine system. For instance, if the check engine light is illuminated, the remote start feature may be disabled as a precautionary measure. Therefore, it is advisable to address any engine-related warnings before attempting to use the remote start function.

Moreover, the remote start system may also be affected by environmental factors. For instance, if the vehicle is parked in an area with poor signal reception, such as a garage or a densely populated area, the remote start signal may not reach the vehicle effectively. In such situations, moving to a location with a clearer line of sight can improve the chances of successfully engaging the remote start feature.

Lastly, software glitches or updates may also contribute to remote start failures. Like many modern vehicles, the Subaru Ascent relies on software to manage various functions, including remote start. If the software is outdated or has encountered a glitch, it may hinder the remote start capability. Regularly checking for software updates and ensuring that the vehicle’s systems are functioning correctly can help mitigate this issue.

In conclusion, while the remote start feature of the Subaru Ascent is a convenient and desirable function, several factors can lead to its failure. By understanding the common reasons behind these issues, owners can take proactive steps to troubleshoot and resolve them, ensuring that they can enjoy the full benefits of their vehicle’s technology.

Troubleshooting Tips for Subaru Ascent Remote Start Issues
