2015 Subaru Touch Screen Not Working

The 2015 Subaru Outback and Legacy models, equipped with a factory touch screen infotainment system, have been reported to experience touchscreen malfunctions. These issues can range from unresponsiveness to erratic behavior, impacting usability and potentially driver safety. This article presents a factual overview of known issues and potential remedies.

Common Touch Screen Issues

Reports from owners and service technicians indicate several recurring problems with the 2015 Subaru touch screen:

Unresponsiveness

This is perhaps the most frequently reported issue. The touchscreen may become completely unresponsive to touch inputs. This means the driver cannot control audio functions, navigation (if equipped), climate control (in some trims), or access vehicle settings through the screen. The radio and other functions might still operate, but the touch interface is unusable.

Erratic Behavior

Instead of being entirely unresponsive, the screen might register touches in incorrect locations or perform unintended actions. For example, touching one icon might activate a different function, or the screen might randomly select options without any user input. This "ghost touching" can be distracting and dangerous while driving.

Freezing or Crashing

The entire infotainment system can freeze, leaving the screen displaying a static image. In some cases, the system may reboot spontaneously. These freezes can interrupt audio playback, navigation guidance, and other functions.

Dim or Dark Screen

While not strictly a touchscreen malfunction, a dim or completely dark screen makes the system unusable. This could be due to a backlight failure within the screen itself or an issue with the power supply to the display.

Possible Causes

Identifying the root cause of touchscreen problems can be challenging, as several factors could contribute to the issue. Here are some potential causes:

Software Glitches

Software bugs or corrupted data within the infotainment system's operating software can lead to erratic behavior or complete unresponsiveness. Subaru has released software updates for these systems over time, and applying the latest update is often the first step in troubleshooting.

Hardware Failure

The touchscreen itself or the internal components of the infotainment unit can fail. This could be due to manufacturing defects, age-related degradation, or physical damage (e.g., from extreme temperatures or impacts). Hardware failures often require replacement of the affected component.

Loose Connections

Loose or corroded wiring connections within the infotainment system can disrupt the flow of power or data, leading to malfunctions. Vibration from driving can sometimes loosen connectors over time. Inspecting and cleaning connections is a potential solution.

External Interference

Although less common, external electromagnetic interference (EMI) from aftermarket devices or nearby electronic equipment could potentially disrupt the touchscreen's operation. However, this is a relatively rare cause.

Defective Digitizer

The digitizer is the component within the touchscreen that detects touch input. If the digitizer fails, the screen will not register touches correctly, or at all. Digitizer replacement is a repair option in some cases, but often the entire screen assembly must be replaced.

Troubleshooting Steps

Before seeking professional repair, there are a few troubleshooting steps that owners can try:

Restarting the System

A simple reboot can often resolve temporary software glitches. This can usually be done by turning off the vehicle, removing the key, waiting a few minutes, and then restarting the engine. Consult the owner's manual for specific instructions on restarting the infotainment system (if available). In some cases, disconnecting the car battery for a short period can also perform a system reset.

Checking for Software Updates

Visit a Subaru dealership or check the Subaru website to determine if there are any available software updates for the infotainment system. Applying the latest update can fix known bugs and improve performance.

Cleaning the Screen

Dirt, fingerprints, or other debris on the screen can sometimes interfere with touch sensitivity. Use a soft, clean, lint-free cloth to gently clean the screen. Avoid using harsh chemicals or abrasive cleaners.

Checking Fuses

Consult the owner's manual to locate the fuse for the infotainment system and check if it is blown. A blown fuse can prevent the system from powering on or functioning correctly.

Professional Repair Options

If the troubleshooting steps above do not resolve the issue, professional repair may be necessary.

Subaru Dealership

A Subaru dealership has the expertise, diagnostic tools, and access to genuine Subaru parts to properly diagnose and repair touchscreen problems. Dealership technicians can perform software updates, diagnose hardware failures, and replace defective components.

Independent Repair Shops

Some independent repair shops specialize in automotive electronics and infotainment systems. These shops may offer more competitive pricing than dealerships, but it's important to choose a reputable shop with experienced technicians.

Replacement Options

Depending on the severity of the problem and the cost of repair, replacing the entire infotainment unit may be the most practical option. There are aftermarket infotainment systems available that are compatible with the 2015 Subaru models. These aftermarket systems may offer enhanced features and performance compared to the factory system. It is crucial to ensure compatibility with the vehicle's existing wiring and features (e.g., backup camera, steering wheel controls) before installing an aftermarket system.

Warranty Considerations

The original factory warranty for the 2015 Subaru models has likely expired. However, if the vehicle is covered by an extended warranty or a certified pre-owned warranty, touchscreen repairs may be covered. Check the terms of the warranty to determine the coverage.

Preventative Measures

While not always possible, some measures can help to potentially prolong the life of the touchscreen:

Avoid Extreme Temperatures

Prolonged exposure to extreme heat or cold can damage electronic components. Park the vehicle in the shade or use a sunshade to protect the dashboard from direct sunlight.

Gentle Handling

Avoid pressing too hard on the touchscreen or using sharp objects that could scratch or damage the screen.

Regular Cleaning

Clean the screen regularly to remove dirt, fingerprints, and other debris.

Keep Software Updated

Install software updates as soon as they become available to fix bugs and improve performance.
