Visibility/wiper, Jan 10, 2022
While driving down the interstate, no other vehicles in sight, heard a pop and immediately a crack formed in the windshield (at the bottom in the exact middle of the glass) which spread vertically and has since branched out horizontally. A matter of seconds before this happened, I engaged the defrost button. This is the SECOND windshield to crack spontaneously since I purchased the vehicle in December 2020. The first replacement was proven to not installed properly and Subaru paid for the replacement. As the crack continues to grow, I feel my safety could be affected if the EyeSight features fail as a result of this issue not being addressed.

Fragile windshield. I’m just under a year of ownership and I replaced the windshield twice so far so I’m on my third one. First time was about a month in, no visible strike mark. Started on the Driver side halfway up and spread daily horizontally towards the passenger side and within a day or two was half the windshield. Second one was nine or 10 months out. Tiny strike basically did the same spread. In traffic a tiny rock got tossed up at low speed and I have a Starbust right now. Hopefully it won’t spread overnight before I can get it epoxied because then I will be on my fourth windshield before one year of ownership. Decades of other models and cars and same driving locations and I’ve never had to replace a windshield or repair one. Currently at 16K miles.

In February 2021 my windshield was cracked in the lower left corner for an unknown reason. Windshield was inspected by manufacturer service center and thought to be result of an impact and was then replaced. December 2021 the windshield was again cracked in the lower left corner and again needs to be replaced. Appears to also be the result of an impact but will need to be determined by insurance. Both instances the windshield cracked in the bottom left corner and the crack began to quickly grow across the drivers side to the top center of the windshield.

The sunroof on my 2021 Subaru Outback exploded for no apparent reason while I was driving. There was no impact by any object, and the glass shattered into innumerable pieces, suggesting it was definitively tempered, not laminated, glass. The weather was sunny and 50 degrees Fahrenheit. I happened to have my sunroof shade closed - if I hadn’t, I would have gotten glass in my hair and possibly in my eyes while driving my car.

We purchased a new 2021 Outback Subaru 2 months ago. Three days ago, on 11/12/21, a crack appeared on the windshield overnight, while the car was parked on our driveway. Nothing hit our car while we were driving and there's nothing that stands above the car that could have fallen on it while parked at our house. The crack is linear and started on the very left side right above the driver's sight. It started at about 5 inches long and the next day was already extending almost halfway through the windshield length. We are highly suspicious that the crack is a result of a defective windshield specially after learning that Subaru has several lawsuits regarding this same issue. We had to stop driving the car in fear that the windshield may completely break at any time. My husband contacted Subaru twice and the representatives told him someone would soon contact him about the incident. Nobody contacted us for the next two days. My husband then called Subaru and they said it would cost $1,500 to fix it.

Windshield spontaneously cracked on passenger side at eye level after 5 months, 5,700 miles
Visibility/wiper, Oct 13, 2021
I am on my third cracked windshield in FOUR MONTHS! First crack in July 2021, second in August 2021, third in early October 2021. Haven’t replaced the latest as I’m concerned about insurance rate increases. Each time the crack appears in the bottom of the drivers side and spreads to more than 12 inches in minutes. Summer in Utah is typically not problematic for cracked windshields. All windshields have been replaced with Subaru product as aftermarket products don’t exist.

A small object struck the windshield on the lower driver side, it created a horizontal crack about 1.5 ft long within a minute.
Visibility/wiper, Sep 28, 2021
This is my second experience with a cracked windshield in the 6 months I have owned this vehicle. The first time the windshield cracked I was driving on the interstate and the windshield simply cracked. No debris impact, no bumps, just a long crack running from the top center of the glass down apx 8 inches. Subaru replaced under warranty. The second time the glass cracked I was driving on the interstate and was hit by a small piece of debris. So small it took a moment to find the point of impact. The crack immediately started to spread and after a few hours was apx 12 inches long. After apx 2 weeks the crack has run and is apx 2.5 feet. Insurance claim has been filed, but due to a shortage of glass the repair has not been completed.

My wife has purchased Subaru 2021 Outback on May 2021. The windshield got cracked while it was parked in a driveway. It looks there was no sign of impact on the crack. The windshield of the Outback looks very susceptible to crack.

During heavy rains, the vehicles leak water into the driver's side wheel well. Numerous times back to the dealer and the vehicle being piece by piece all seals are being replaced. As per numerous blogs on Subaru forums, an indication of a faulty windshield seal could be the issue, but the dealership refuses to replace or reset the windshield seal. Bought the car on June 28, 2021, and have been to the dealership 3 times for the same issue. The dealership is replacing seals on the skylight and door but as of yet no resolution. At the time of this complaint, the vehicle has been at dealership for 3 weeks with no resolution.

While driving on residential street, I heard a pop and saw my windshield crack. My speed at the time of this incident was 30mph. There was no impact with a foreign object. Crack is in front of the Eyesight camera and is affecting the functionality of vehicle's safety features. This is a 2021 Outback with approximately 3200 miles.

The windshield cracked shortly after purchase. We had the windshield replaced and within 4 months the windshield is now chipped in three places. This is a safety issue because a cracked windshield impairs visibility while driving.

Windshield spontaneously cracked where the mirror was atached to the glass. There is a concave indentation where the mirror was attached and we found the mirror hanging by a wire and small glass pieces on the dash. Temps were in the low 90s. No one has modified or put any unusual pressure on the mirror, no decorations were attached. The outside of the glass has no chips or cracks anywhere in the glass which was confirmed by the local Safelite dealer. This vehicle was purchased new on May 7, 2021. Location of incident was Temecula, CA. I asked the local dealer to repair under warranty and was told that there is no manufacturer warranty on glass. Obviously having your windshield spontaneously crack and the rearview mirror falling off would be a distraction at highway speeds.

Car was parked outside. We returned to vehicle and noticed that front windshield had large crack beginning in bottom right and was 2-3 feet in length. The crack grew overnight. This was in a place of business and we do not suspect vandalism. It was a hot day (over 90-degrees with humidity). The air conditioner had been running inside the vehicle. Vehicle has less than 6,000 miles.
