Subaru Ascent Remote Start Problems: Troubleshooting & Fixes

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.

Another common issue that can impede the remote start functionality is the vehicle’s transmission status. The Subaru Ascent is designed with safety features that prevent remote starting when the transmission is not in the proper position. For instance, if the vehicle is in gear rather than in the park position, the remote start will not engage. It is crucial for drivers to double-check that the transmission is indeed in the park position before attempting to start the vehicle remotely. Furthermore, if the vehicle has been recently serviced or if there have been any changes to the transmission system, it may be worthwhile to consult a professional to ensure everything is functioning correctly.

Environmental factors can also play a significant role in the effectiveness of the remote start feature. Extreme weather conditions, such as very low temperatures or heavy precipitation, can affect the performance of the key fob and the vehicle’s electronic systems. In cold weather, for example, the battery in the key fob may drain more quickly, leading to a reduced range or failure to operate. Similarly, if the vehicle is parked in a location with poor signal reception, such as an underground garage, the remote start may not work as expected. In such cases, moving to a more open area may resolve the issue.

Additionally, software glitches or updates can occasionally disrupt the remote start functionality. Like many modern vehicles, the Subaru Ascent relies on complex software systems to manage various features, including remote start. If there has been a recent software update or if the system has encountered a glitch, it may temporarily affect the remote start feature. In these situations, resetting the vehicle’s systems or consulting with a Subaru dealership for diagnostic assistance may be necessary.

In conclusion, while the remote start feature of the Subaru Ascent is a convenient and desirable function, several factors can contribute to its failure. By ensuring that the security system is intact, the transmission is in the correct position, environmental conditions are favorable, and the software is up to date, owners can troubleshoot and potentially resolve issues with remote start functionality. If problems persist, seeking professional assistance is advisable to ensure that the vehicle remains in optimal working condition.

Troubleshooting Tips for Subaru Ascent Remote Start Issues

When experiencing issues with the remote start feature of a Subaru Ascent, it is essential to approach the problem methodically to identify and resolve the underlying cause. First and foremost, it is advisable to ensure that the vehicle is equipped with the remote start option, as not all models come with this feature as standard. If the vehicle is indeed equipped with remote start, the next step is to check the key fob’s battery. A weak or dead battery in the key fob can prevent the remote start function from operating correctly. Replacing the battery is a simple task that can often resolve the issue.

In addition to checking the key fob battery, it is crucial to verify that the vehicle is within the operational range of the remote start system. The remote start feature typically has a limited range, and if the vehicle is too far away, the command may not be received. Therefore, standing closer to the vehicle when attempting to use the remote start can help determine if distance is a factor. Furthermore, environmental conditions can also play a role; extreme weather, such as heavy rain or snow, may interfere with the signal transmission.

Another important aspect to consider is whether the vehicle’s doors are properly closed and locked. The remote start system is designed to prevent unauthorized use, which means that if any door is ajar, the system will not activate. Ensuring that all doors, including the trunk and hood, are securely closed can help eliminate this potential issue. Additionally, if the vehicle is equipped with a manual transmission, it is essential to ensure that the gear shift is in the neutral position, as the remote start feature will not engage if the vehicle is in gear.

Moreover, it is worth checking the vehicle’s security system. If the alarm is triggered or if there are any issues with the immobilizer, the remote start function may be disabled. In such cases, consulting the vehicle’s owner manual for specific instructions on resetting the security system can be beneficial. If the problem persists, it may be necessary to inspect the vehicle’s fuses related to the remote start system. A blown fuse can disrupt the functionality of the remote start feature, and replacing it may restore normal operation.

If all these troubleshooting steps do not yield results, it may be time to consider potential software issues. Occasionally, the vehicle’s onboard computer may require a reset or an update to function correctly. Visiting a certified Subaru dealership or a qualified automotive technician can provide access to diagnostic tools that can identify any software-related problems. They can also check for any recalls or service bulletins that may pertain to the remote start system.

In conclusion, while encountering issues with the remote start feature of a Subaru Ascent can be frustrating, a systematic approach to troubleshooting can often lead to a resolution. By checking the key fob battery, ensuring proper range and door security, and inspecting the vehicle’s systems, owners can identify and address the problem effectively. If these steps do not resolve the issue, seeking professional assistance is advisable to ensure that the vehicle’s remote start system is functioning as intended.
