Windshield cracking in 2015–2019 Subaru Outbacks has been a common concern for owners. Various factors contribute to these cracks, and addressing them involves understanding both their causes and potential solutions.

 
Causes of Windshield Cracking
 

Different factors can lead to windshield cracking in Subaru Outbacks from these model years:

• **Material and Design Flaws:** Some owners and experts suggest that the material used in the windshields of these Subaru Outbacks might not be as durable as expected, potentially leading to increased susceptibility to cracking.
• **Temperature Fluctuations:** Windshields can crack due to sudden changes in temperature. For Subaru Outbacks, especially those driven in areas with significant temperature shifts, the expansion and contraction of glass can lead to stress cracks.
• **Stress from Poor Installation:** In cases where the windshield was not installed correctly, stress points can occur, which may result in cracking over time due to road vibrations and pressure changes.
• **Road Debris Impact:** As with any vehicle, impacts from stones and road debris can lead to cracks. This can be more pronounced in vehicles that frequently travel on gravel roads or highways with loose debris.
• **Frequent or Severe Environmental Exposure:** Exposure to harsh environmental conditions such as heavy sun or rain can cause gradual wear and tear on the windshield, contributing to cracking.

 
Resolving Windshield Cracking Issues
 

Resolving and preventing windshield cracks involve several steps ranging from immediate fixes to preventive measures:

• **Regular Inspection and Maintenance:** Periodically inspect your windshield for small chips or cracks that can expand over time. Addressing these small imperfections immediately with a repair kit or professional help can prevent larger cracks from forming.
• **Quality Replacement and Installation:** When replacing a windshield, ensure that it is done by a certified professional using high-quality glass specifically designed for Subaru Outbacks. Proper installation can reduce stress points and potential future cracking.
• **Protective Measures:** Applying a protective film or coating to your windshield can provide an additional layer of defense against road debris and environmental factors.
• **Park Strategically:** Whenever possible, park your vehicle in the shade or use a sunshade to reduce the internal temperature and minimize the risk of thermal shock from direct sunlight.
• **Subaru Service Bulletins and Recalls:** Stay informed about any recalls or service bulletins issued by Subaru that specifically address windshield issues. In some cases, manufacturers will offer service programs to replace or repair faulty windshields.
• **Insurance Considerations:** Check with your insurance provider to understand what is covered in case of windshield cracking. Many policies offer comprehensive coverage for glass damage, which can reduce out-of-pocket expenses.

By understanding and addressing the potential causes of windshield cracking, 2015-2019 Subaru Outback owners can take steps to protect their vehicles and reduce the likelihood of needing frequent windshield replacements or repairs.
