Too Many Subarus Suffer From Spotaneously Cracked Windshields

Chances are you've probably heard a rock hitting your windshield hard enough to crack it at some points. It's jarring and not a lot of fun. But at least you can explain what's going on.

It's a different beast entirely when the cracks form in the windshield spontaneously. Especially on newer car with only a few thousands miles on the odometer.

Or to cars that are just sitting at a stoplight when the crack forms. Or resting in a garage overnight.

A Few Possible Explanations

Unlike a chipped windshield, where the crack starts from the point of impact and slowly spiders out over time, these cracks are developing quickly and often starting at the bottom of the windshield where the wipers are located.

But why?

The switch to acoustic windshields

An acoustic windshield has more sound dampening capabilities than a normal windshield. The added layers of soundproofing can make a significant improvement to reducing wind, tire, and other outside noise while driving.

It's a nice improvement, but they might not be all they're cracked up to be considering complaints about this problem took a steep turn around the same time Subaru made the switch to acoustic windshields.

De-icer adhesion issues

During a warranty extension to 2015 and early production 2016 Legacy and Outback vehicles, Subaru explained that certain compounds used to adhere the deicer to the lower portion on the windshield created a situation where "the glass become more susceptible to cracking following a minor wound" due to some outside force.

Cost cutting and fuel efficiency considerations

Another possible explanation is the thickness of the windshield glass itself.

Subaru vehicles tend to get good gas mileage, but glass is heavy and shaving a few pounds off can boost a car's MPG ratings. Glass is also expensive and so shaving off a few pounds can also boost the CEO's net worth.

Implications of a Constantly Cracking Windshield

Cracked windshields are expensive enough to replace on their own. But, according to many owners, the costs don't stop with the glass.

  • EyeSight needs to be recalibrated when the windshield is replaced. And Subaru won't do that for free.
  • It can interfere with the proper deployment of airbags and can reduce the structural integrity of a vehicle in a crash.

All of which is to say, you need to get it replaced quickly. And that's not cheap.

TSB Leads to a Warranty Extension for Certain Outback and Forester Vehicles

In TSB #12-192-15R, Subaru acknowledged that the "ceramic materials used for the black-colored printed perimeter combined with the silver-colored material used for the wiper deicer portion of the windshield glass" is the root cause of many windshield failures.

Subaru offered a "quality assurance" program by extending the windshield warranty from 3 years/36,000 miles to 5 years/unlimited mileage for 2015 and early-production 2016 Legacy and Outback vehicles.

Subaru also offered reimbursement options for owners who had previously paid for repairs, but eligibility requirements made it nearly impossible to receive full reimbursements. They also refused to reimburse anyone who used a 3rd party, like companies their insurance might have suggested, if the company didn't replace the windshield with OEM glass.

The deadline for reimbursements passed on February 1st, 2016.

A Series of Lawsuits Says Subaru Didn't Go Far Enough

Since the extended warranty was offered to just a couple 2015 models, Subaru has faced multiple lawsuits regarding their outright refusal to cover the cost (and related costs) of numerous windshield replacements in newer models.

Plaintiffs say the windshield defect poses an "imminent and significant safety hazard" and that the switch to "acoustic glass" that is to blame for the multitude of failures.

Cases consolidated

Two cases, Leon and Powell, were consolidated into one class-action covering roughly 2.5 million vehicles:

  • 2017-2020 Subaru Forester
  • 2017-2020 Subaru Outback
  • 2017-2020 Subaru Crosstrek
  • 2017-2020 Subaru Legacy
  • 2017-2020 Subaru Impreza

Unfortunately the Ascent was dropped from the list.

In March 2020, Subaru asked for a motion to dismiss saying the cases do not allege that Subaru vehicles fail to comply with federal safety standard #205.

They also claim the cases are too broad and consist of "two different design generations of four of those five models." Which is a problem for the case's credibility because Subaru used multiple windshield suppliers over that period of time.

Of course, that could just mean they were all incompetent, but that is up to a judge now.

Generations Where This Problem Has Been Reported

This problem has popped up in the following Subaru generations.

Most years within a generation share the same parts and manufacturing process. You can also expect them to share the same problems. So while it may not be a problem in every year yet, it's worth looking out for.

  1. The lawsuit against Subaru's crappy windshields will move forward after partially surviving the automaker's motion to dismiss.

    The windhsields crack and chip at an alarming rate, but Subaru doesn't cover replacements under warranty if the issue is due to a defect. According to them the warranty only covers material or workmanship issues. Strange position to take, but ok.

    While a few allegations were removed due to legal technacilities, the judge said dismissing the case entirely at this point would be premature.…

What Owners Say About This Problem

The 2019 Subaru Forester was less than a week old. I was driving down the road, no one or nothing near me, and I heard a pop. I then saw the crack in the windshield ... I found other reports of windshield issues, took the information to the dealer, and they reluctantly replaced the windshield.

2019 Forester Owner in FL

Because I have the Eyesight feature, I cannot replace the glass with aftermarket glass. It has to be OEM glass from the dealership. The glass is thin (2 layers sandwiching a thin film for noise reduction) and brittle resulting in the exterior layer cracking easily. Owning a Toyota for 15 years.... no cracked or broken windshields. Owning a Subaru 3 months... 2 cracked windshields.

2019 Crosstrek Owner in FL

Six days after I bought a 2019 Subaru Outback, I noticed a crack developing from the top on the driver's side, close to the middle of the car. I thought it was a small streak of water at first. But as it didn't dry, I realized the windshield had cracked. I didn't see or hear anything hit it. No trucks around, and the road was smooth, free of debris.
