What Subaru models are being draining battery?
Subaru vehicles are known for their reliability and performance, but like any car brand, they can experience specific issues. One recurring problem reported by Subaru owners is unexpected battery drainage. In this article, we’ll explore which Subaru models are most commonly affected by this issue, the potential causes, and what you can do to address it.
Subaru Models Commonly Affected by Battery Drainage
Several Subaru models have been reported to experience battery drainage issues. These include:
- Subaru Outback (2016-2020): Many owners of these models have reported battery problems, often linked to electrical components that fail to shut off properly.
- Subaru Forester (2019-2021): The Forester has also been noted for battery drainage, particularly in models equipped with advanced safety features like EyeSight.
- Subaru Ascent (2019-2021): This model has been flagged for similar issues, with some owners citing problems with the infotainment system and other electronics.
- Subaru Crosstrek (2018-2020): Battery complaints have been less frequent but still notable, often tied to accessory usage.
While these models are the most commonly reported, it’s important to note that battery issues can occur in any vehicle due to various factors.
Potential Causes of Battery Drainage
Battery drainage in Subaru vehicles can stem from several sources. Here are the most common causes:
- Electrical System Glitches: Features like the infotainment system, keyless entry, and EyeSight driver-assist technology may fail to power down completely, leading to a slow drain on the battery.
- Parasitic Drain: This occurs when electrical components continue to draw power even when the car is turned off. Faulty wiring or malfunctioning modules can exacerbate this issue.
- Short Driving Distances: Frequent short trips may not allow the alternator enough time to recharge the battery fully, especially if the vehicle is equipped with power-hungry features.
- Old or Weak Battery: A battery nearing the end of its lifespan is more susceptible to drainage issues, particularly in vehicles with advanced electronics.
Understanding these causes can help you identify and address the problem more effectively.
How to Address and Prevent Battery Drainage
If you’re experiencing battery issues with your Subaru, here are some steps you can take:
- Check for Recalls or Service Bulletins: Subaru has issued service bulletins for certain models to address battery-related issues. Contact your dealer to see if your vehicle is affected.
- Inspect Electrical Components: Have a professional mechanic check for parasitic drains or malfunctioning systems that may be causing the problem.
- Upgrade Your Battery: If your battery is old or underpowered, consider replacing it with a higher-capacity model designed to handle your vehicle’s electrical demands.
- Limit Accessory Usage: Avoid leaving lights, chargers, or other accessories plugged in when the vehicle is off.
- Drive Regularly: Ensure your vehicle is driven regularly and for sufficient distances to allow the alternator to recharge the battery.
By following these steps, you can reduce the likelihood of battery drainage and keep your Subaru running smoothly.
