The 2021 Subaru Forester, a popular choice for its reliability and off-road capabilities, is generally a dependable vehicle. However, like any car, it's not immune to potential issues. Knowing about these common problems can help you stay informed, prepare for possible repairs, and make the best decisions for your Forester's long-term health.

So, What Are We Talking About Here? Common Issues with the 2021 Forester

While the 2021 Forester boasts a strong reputation, a few areas have emerged as potential trouble spots for some owners. These range from minor annoyances to more significant concerns that could impact your driving experience. Let's dive in and explore the most frequently reported problems.

Battery Blues: Why Won't My Forester Start?

One of the most prevalent issues reported by 2021 Forester owners revolves around battery drain. Many have experienced instances where the battery dies prematurely, especially after the car has been sitting for a relatively short period. This can be incredibly frustrating, leaving you stranded and needing a jump start.

Why is this happening? Several factors could contribute to this battery drain issue:

  • Faulty Battery: Sometimes, the battery itself is the culprit. A manufacturing defect or internal damage can cause it to lose its charge quickly.
  • Parasitic Drain: This occurs when electrical components continue to draw power even when the car is turned off. Potential culprits include the infotainment system, security system, or even a faulty sensor.
  • Short Trips: Frequent short trips may not give the alternator enough time to fully recharge the battery, especially if you're using power-hungry accessories like heated seats or the air conditioning.
  • Software Glitches: In some cases, software issues within the car's computer system could be preventing the battery from charging correctly or causing unnecessary drain.

What can you do about it?

  • Battery Testing: The first step is to have your battery professionally tested at an auto parts store or service center. This will determine if the battery itself is the problem.
  • Parasitic Draw Test: A mechanic can perform a parasitic draw test to identify any components that are draining power while the car is off.
  • Software Updates: Check with your Subaru dealer to see if there are any available software updates for your Forester. These updates might address battery management issues.
  • Battery Maintenance: Ensure your battery terminals are clean and free of corrosion. Consider using a battery maintainer if you frequently drive short distances or leave your car parked for extended periods.
  • Consider a Higher CCA Battery: If you live in a cold climate, upgrading to a battery with a higher cold cranking amps (CCA) rating can help ensure reliable starts in freezing temperatures.

Infotainment System Headaches: Is Your Screen Acting Up?

Another common complaint among 2021 Forester owners centers on the infotainment system. Many have reported issues with freezing, lagging, and even complete system crashes. These problems can be incredibly distracting and frustrating, especially while driving.

What's causing the infotainment system issues?

  • Software Glitches: Infotainment systems are complex software-driven devices. Bugs and glitches can cause them to malfunction.
  • Overloaded System: Running too many apps or having too many devices connected simultaneously can strain the system's processing power, leading to slowdowns and crashes.
  • Hardware Problems: In rare cases, the infotainment system's hardware itself may be faulty.
  • Connectivity Issues: Problems with Bluetooth connectivity or Wi-Fi can also contribute to infotainment system instability.

How to Tackle Infotainment Troubles:

  • Software Updates: Regularly check for software updates for your infotainment system. These updates often include bug fixes and performance improvements.
  • System Reset: Try performing a soft reset of the infotainment system. This usually involves holding down the power button for an extended period. Refer to your owner's manual for specific instructions.
  • Factory Reset: If a soft reset doesn't work, you can try a factory reset. However, be aware that this will erase all your saved settings and preferences.
  • Limit App Usage: Avoid running too many apps simultaneously and disconnect any unnecessary devices.
  • Professional Diagnosis: If the problems persist, take your Forester to a Subaru dealer for a professional diagnosis and repair.

Eyesight System Glitches: Is Your Safety Tech Giving You Trouble?

Subaru's Eyesight system is a suite of advanced driver-assistance features designed to enhance safety. However, some 2021 Forester owners have reported experiencing glitches with this system, including false alerts, system malfunctions, and even temporary shutdowns.

Why is Eyesight acting up?

  • Sensor Obstruction: Dirt, snow, or ice can obstruct the Eyesight cameras, causing the system to malfunction.
  • Poor Lighting Conditions: Extreme sunlight or darkness can affect the system's ability to function properly.
  • Software Issues: Like the infotainment system, the Eyesight system relies on complex software, which can be prone to bugs.
  • Miscalibration: The Eyesight cameras need to be properly calibrated to ensure accurate readings. If they're misaligned, the system may not function correctly.

Troubleshooting Eyesight Problems:

  • Clean the Windshield: Ensure the windshield area in front of the Eyesight cameras is clean and free of obstructions.
  • Check for Updates: Verify that your Eyesight system has the latest software updates installed.
  • Restart the Car: Sometimes, simply turning off the car and restarting it can resolve temporary Eyesight glitches.
  • Professional Calibration: If the problem persists, take your Forester to a Subaru dealer for Eyesight system calibration.

Oil Consumption Concerns: Burning Through Oil Too Quickly?

While not as widespread as some other issues, some 2021 Forester owners have reported excessive oil consumption. This means they're needing to add oil more frequently than expected between oil changes.

Why is my Forester consuming so much oil?

  • Engine Break-In: It's normal for some engines to consume slightly more oil during the initial break-in period.
  • Driving Habits: Aggressive driving, such as frequent hard acceleration and high speeds, can increase oil consumption.
