While driving on the highway around 65mph, the windshield was struck by a small piece of debris, no larger than a nickel in diameter. This initially produced a small crack at the base of the windshield on the driver's side, which quickly lengthened to over 12 inches over the course of the day. Especially under bright sunlight, the crack produces a sharp glare which significantly reduces driver visibility. When running my finger along the crack, I cannot feel any crack. There is no chip in the glass. The crack is internal to the windshield. (See photo included with this incident submission.) This seems to be a defect in the windshield quality that other Subaru Forester owners have also reported.

I HAVE NOW REPLACED MY WINDSHIELD A SECOND TIME IN A 30-DAY PERIOD OF TIME. I HAD MY WINDSHIELD BREAK WHILE I WAS DRIVING DOWN THE ROAD AND DID NOT SEE ANYTHING HIT THE WINDSHIELD BEFORE THIS HAPPENED. AS SOON AS I GOT IT REPLACED, 3 DAYS PAST AND I WOKE UP ONE MORNING TO SEE THAT MY WINDSHIELD WAS BROKEN AGAIN. NOTHING HIT THE WINDSHIELD EITHER TIME AND IT JUST SPORADICALLY CRACKED. I'M DREADING HAVING TO PAY FOR THE THIRD REPLACEMENT.
MY WINDSHIELD HAS CRACKED AND HAD TO BE REPLACED TWICE SINCE PURCHASING THE CAR WITH ONLY 41,000 MILES ON IT CURRENTLY. IT IS A 2017 SUBARU FORESTER AND THERE ARE NOW 2 CRACKS IN THE THIRD AND CURRENT WINDSHIELD.THE WINDSHIELDS THEY ARE USING ARE UNSAFE AND COST ROUGHLY $1300 TO REPLACE DUE TO THE EYE SIGHT SYSTEM.

MY WINDSHIELD HAS CRACKED AND HAD TO BE REPLACED TWICE SINCE PURCHASING THE CAR WITH ONLY 41,000 MILES ON IT CURRENTLY. IT IS A 2017 SUBARU FORESTER AND THERE ARE NOW 2 CRACKS IN THE THIRD AND CURRENT WINDSHIELD.THE WINDSHIELDS THEY ARE USING ARE UNSAFE AND COST ROUGHLY $1300 TO REPLACE DUE TO THE EYE SIGHT SYSTEM. SUBARU IS INSTALLING THESE UNSAFE WINDSHIELDS KNOWINGLY AND COLLECTING MASSIVE PROFITS FROM ALL THE REPLACEMENTS.
FORESTER WINDSHIELD STARTED CRACKING FOR NO CLEAR REASON, SPREAD QUICKLY TO A 20" OR LONGER CRACK THAT CONTINUES TO SPREAD.
FRONT WINDSHIELD HAS DEVELOPED TWO LINEAR CRACKS SPONTANEOUSLY, ONE SMALL ONE 5 CM LONG, THE OTHER ACROSS THE DRIVER'S SIDE WINDSHIELD ABOUT 50 CM. THIS APPEARS TO HAVE OCCURRED SPONTANEOUSLY, THERE WAS NO DEBRIS, ETC, FIRST NOTED WHILE VEHICLE WAS IN GARAGE. THERE ARE NO STELLATE MARKINGS, ETC.
I PURCHASED MY 2017 SUBARU FORESTER IN JULY 2017, SO I'VE OWNED THE VEHICLE FOR ALMOST 4 YEARS. ONE DAY RECENTLY I GOT IN MY VEHICLE AND NOTICED A MASSIVE STRESS CRACK IN THE WINDSHIELD. THE VEHICLE WAS PARKED OUTSIDE OF MY HOME AND I HAD NOT PREVIOUSLY SEEN ANY CRACKS ON THE WINDSHIELD. THE CRACK IS AROUND 12 INCHES IN LENGTH, …

I PURCHASED MY 2017 SUBARU FORESTER IN JULY 2017, SO I'VE OWNED THE VEHICLE FOR ALMOST 4 YEARS. ONE DAY RECENTLY I GOT IN MY VEHICLE AND NOTICED A MASSIVE STRESS CRACK IN THE WINDSHIELD. THE VEHICLE WAS PARKED OUTSIDE OF MY HOME AND I HAD NOT PREVIOUSLY SEEN ANY CRACKS ON THE WINDSHIELD. THE CRACK IS AROUND 12 INCHES IN LENGTH, MAYBE LONGER. IT STARTS AT THE BASE OF THE WINDSHIELD ON THE DRIVER'S SIDE AND EXTENDS MOSTLY HORIZONTALLY TOWARD THE PASSENGER SIDE. I RAN MY FINGER END TO END ACROSS THE CRACK BOTH OUTSIDE THE VEHICLE AND INSIDE THE VEHICLE AND I COULD NOT FEEL THE CRACK. WHICH MEANS THE CRACK IS ON THE INSIDE OF THE WINDSHIELD, WHICH MAKES ME THINK IT IS A STRESS CRACK. THIS IS A COMMON ISSUE WITH NUMEROUS SUBARU VEHICLES OF VARIOUS MAKES, MODELS, AND YEARS. MY 2017 SUBARU FORESTER IS INCLUDED IN THE LIST OF VEHICLES THAT IS AFFECTED. SUBARU HAS A CLASS ACTION LAWSUIT AGAINST THEM BECAUSE THIS ISSUE OF SUBARU WINDSHIELDS CRACKING IS SO COMMON.

WHILE DRIVING STRAIGHT FORWARD ON A WELL-MAINTAINED HIGHWAY UNDER NORMAL ROAD CONDITIONS MY CAR HAS BEEN HIT WITH SEVERAL ROCKS THAT HAVE BEEN FLUNG FROM TRUCK WHEELS INTO MY LANE. MY CAR'S WINDSHIELD CHIPPED AND CRACKED IN AN UNUSUALLY EASY AND VIOLENT MANNER. ONE OF THE CRACKS SPECIFICALLY SEEMS LIKE A HAZARD TO THE STRUCTURAL INTEGRITY OF THE GLASS, AS IT IS EASILY SPREADING WITH ANY PRESSURE ON THE WINDSHIELD. I HAVE ONLY HAD THIS CAR FOR 6 MONTHS, AND I HAVE 7 (POSSIBLY MORE) VISIBLE ROCK CHIPS AND CRACKS ON THE WINDSHIELD. MY PRIOR SUBARU WAS AN OLDER (2001) MODEL AND I NEVER EXPERIENCED A VISIBLE ROCK CHIP IN 8 YEARS OF OWNERSHIP.

119V701000 · Air Bags:sensor:occupant Classification
Oct 3, 2019
Subaru of America, Inc. (Subaru) is recalling certain 2015-2018 Forester vehicles equipped with heated seats. An electrical connection in the front passenger seat for the Occupant Detection System (ODS) may loosen.
Consequence & remedy
Consequence: If the connection loosens, the front passenger airbag may deactivate even though the seat is occupied, increasing the risk of injury to the front passenger in the event of a crash.
Remedy: Subaru will notify owners, and dealers will inspect and, as necessary, replace the ODS sensor mat harness, free of charge. The recall began February 11, 2020. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WUM-98.

1PE19009 · Occupant Detection System (ods) Failure
Opened Aug 6, 2019 · Closed Jan 22, 2020
Status: closed (inferred from source dates) · Air Bags; Air Bags:frontal; Air Bags:frontal:passenger Side:inflator Module; Air Bags:sensor:occupant Classification
The Office of Defects Investigation (ODI) opened PE19-009 to investigate 51 complaints and additional Early Warning Report (EWR) data related to allegations of front passenger seat Occupant Detection System (ODS) malfunctions in model year (MY) 2016 through 2018 Subaru Forester vehicles. These vehicles use a capacitive type ODS, which is intended to classify the occupant of the passenger seat as either full-sized, small stature, a child seat or other object. The complaints reported the ODS failed to operate properly, the SRS (Supplemental Restraint System) warning light illuminated, and/or the ODS incorrectly suppressed (turned off) the front passenger air bag when the seat was occupied by a full-sized passenger. In a frontal crash that is sufficient to warrant deployment, a suppressed air bag may increase the risk of injury to the occupant of the seat.On August 14, 2019 ODI sent an Information Request (IR) to Subaru requesting information on the subject vehicles and MY 2014-2015 Subaru Forester vehicles.On October 3, 2019, Subaru submitted a Defect Information Report (DIR) to NHTSA describing a safety defect in the passenger-side front airbag Occupant Detection System (ODS) harness of 366,282 MY 2015-2018 Subaru Forester vehicles equipped with seat heaters.The DIR stated that over time, due to a decrease in contact pressure between the terminals in the ODS sensor mat harness, a temporarily unstable electrical connection may be possible. If the connection is temporarily unstable, the ODS may not properly determine the status of the right front seat occupant. If the ODS is unable to correctly determine the status of the front occupant, the airbag warning light may illuminate, and the front passenger airbag may deactivate even though the seat is occupied, increasing the risk of injury to the front passenger in the event of a crash.Using vehicle production data and field occurrence frequency, Subaru determined the potentially affected vehicle production range to be between January 20, 2015 ?and August 1, 2017.In addition, Subaru indicated that over 99 percent of the related MY 2015-2018 field reports with vehicles in the production range involved vehicles with seat heaters.NHTSA's analysis of complaint and warranty claim data showed 1,440 of the complaints and 11,672 of the claims involve vehicles with seat heaters that were built within the production range covered by Subaru's recall.In addition, NHTSA's analysis showed a complaint rate of 393.1 per hundred thousand vehicles for the recalled population and 89.0 for MY 2014 through 2018 vehicles that are not included in the recall. Analysis of warranty claim data found a claim rate of 3.2 percent for the recalled population and 0.3 percent for MY 2014 through 2018 vehicles that are not included in the recall.Subaru will instruct owners with Subaru Forester vehicles produced in the affected vehicle production range, to bring their vehicles to a dealer to have the sensor mat harness, inspected and replaced with a new part, including the seat cushion assembly, if necessary.Based on ODI's analysis, the actions taken by Subaru mitigate any unreasonable risk to safety posed by ODS sensor mat failures in the subject vehicles. For subject and peer vehicles outside the recall population and those equipped without seat heaters, ODI's analysis indicates that there is currently no safety-related defect trend. Given these circumstances, further use of the agency resources in this matter does not appear to be warranted. Accordingly, this investigation is closed.
