Selected complaints filed with NHTSA by 2015 Subaru Legacy owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2015 Subaru Legacy. The contact stated that while the vehicle was turned off on two occasions, the contact observed three cracks in the top-middle of the windshield that led to an 'S' shape crack in the middle of the windshield. The vehicle was taken to an auto body and glass shop where it was diagnosed that the lament had pulled away from the glass and the windshield needed to be replaced. The vehicle was repaired but the failure recurred three weeks later. The manufacturer was not notified of the failure. The failure mileage was approximately 76,000.
My windshield cracked when I used the washer fluid. It cracked from the bottom where the VIN number is and continued across the windshield. I went to the Subaru dealer in Portage Indiana, to have it fixed under the extended warranty I received from Subaru for faulty windshields the dealer told me that it cracked in the wrong spot, and would not be covered. The dealer agreed that the windshield crack was not from any type of impact.
My 2015 Legacy developed a 8 inch crack on the bottom right of the windshield at passenger side last 2 days. No sign of rock hitting, it just chip & crack without any sound. Never have any windshield cracking experienced in my 40 years of driving, with other brand car. It should be a product problem, manufacturer should be under investigate for affected brand/year car. A recall and replacement should be provided to car owner.
I used my windshield washer fluid to wash my windshield and a crack appeared from the bottom driver side of my windshield. I took the car to a Subaru dealership to have the windshield replaced under the Subaru extended windshield warranty program since there was no impact. My claim was denied because the crack was too far towards the driver side of the car.
Sitting in parked vehicle, motor off, windows down heard a quick popping sound. I looked sitting in parked vehicle, engine off, windows down, heard a quick popping noise. A quick inspection, looking around saw nothing. About 20 minutes later driving home, top speed 35 MPH, on a local community road, saw a hairpin crack starting from bottom of window, driver's side, going up across windshield and midway across. The window was clear except for crack. Called a reputable company to schedule appointment. The representative suggested I call the Subaru maintenance department as previous Subaru customers had recall on windshield. I call to learn VIN not a recall. I am extremely happy with my Subaru. I have taken the vehicle back to the Subaru dealer from whom I purchased every six month for oil change and all recommended mileage maintenance inspection. …
1) spontaneous cracks in windshield originating from deicer while car parked overnight 12/3/20 taken to Subaru 12/4/20. Subaru website search showed models with all weather package from my production date had defect in windshield cracking from deicer area & warranty extended 5 yrs which expired 4/20 Subaru May not cover $1000+ cost which involves recalibrating & testing eyesight after replacing windshield (2) eyesight frequently disabled from lights of oncoming vehicles at night or in inclement weather & all safety warnings, emergency braking, adaptive cruise control etc are disabled at time critically needed for driving at night and/or in inclement weather. Paid $400+ for tech to try to duplicate/diagnose problem with front eyesight camera with no solution & now problem is occurring regularly.
Front windshield cracks spontaneously while driving. First occurred on 8/24/17 as described in their TSB with crack starting from the deicer. Dealer replaced under warranty. The newly replaced window cracked once again on 9/19/17. This time dealer refused to replace the windshield under warranty and it is not even a month old, insurance had to cover the costs. OEM is only option for glass with the eye-sight system. Eye-sight also requires calibration by dealership when glass is replaced. The windshield is a critical component to the SRS system when an airbag deploys. Using such fragile glass is a safety concern. High consumer cost when Subaru only covers the first incident. Many complaints from other owners and pending class action lawsuit (luong v. Subaru 4:17-cv-03160-ygr).
I have a 2015 Legacy with 2 window cracks. I received a notice in the mail regarding extended warranty from Subaru that they would cover replacing the windshield. I took it to the dealer today and they said it is not covered that it looks like impact happened to windshield. When I dropped off the vehicle last night there was only 1 crack and today there are 2. There was no impact to the windshield and the dealer says they don't do it there. I need your help. The windshield was defective and Subaru admitted it but the dealers don't want to fix. I will also need the one site re calibrated once the window is replaced which they say is not covered. How could that be? They said I should file an insurance claim which seems like insurance fraud.
I was driving on the interstate at 65 MPH when the car ahead of me must have kicked up a small pebble that hit the windshield. The pebble put a small chip in the passanger side windshield & within 1/2 an hour there was a crack about 6" long running towards the center of the windshield. When I went around a clover leaf exit to get off the interstate the windshield cracked another 6" towards the center of the windshield. The pebble was very small & should have made no more than a small chip in the windshield. I hope the crack will not continue to grow; the windshield must have some kind of manufacturing flaw in it. I hope it is still safe to drive the vehicle as I do not have the $500.00+ to replace the windshield at this time.?
In the course of driving around our area, my wife & I parked our new 2015 Subaru Legacy for an hour to do some shopping. When we got back to the car, we couldn't help but notice a crack on the passenger side front windshield, where there hadn't been one before. We drove immediately to our local Subaru dealer, where they noticed a very small ding just below the right windshield wiper, with the aforementioned crack coming from the ding. From my personal experience of close to 50 years of driving, this is the first ever non-crash windshield problem I've had that's had a progressive crack, and this is a brand new car! I'm reading that I'm not the only one with this problem!
