2025 Subaru Forester

Two occurences of rear hatch window shattering spontaneously while vehicle was parked, powered off. No symptoms, warning lamps, or messages were present. First incident, six months after production/purchase, factory-installed window shattered spontaneously while owner was seated in the car, parked, and engine turned off. Second incident, two months later, OEE replacement window shattered while vehicle was parked, powered off, unattended. Currently having third window installed by dealer and submitting report to Subaru of America.

On March 12, 2026, my 2025 Subaru Forester Hybrid, owned for less than 1 month at the time and purchased on 2/14/2026, sustained a star chip to the windshield during normal driving conditions. While the physical damage itself was minor, the vehicle is equipped with Subaru EyeSight, a camera-based advanced driver assistance system (ADAS) that relies on precise optical clarity through the windshield. I'm now required to have the windshield replaced, because the manufacturer and dealer requires it. According to both Subaru and the vehicle’s owner’s manual (page 15), windshield replacement must be performed using OEM (Original Equipment Manufacturer) glass to ensure proper calibration and safe operation of the EyeSight system. My insurance provider is attempting to authorize the use of aftermarket (non-OEM) windshield glass despite this. This presents a serious safety concern. The EyeSight system controls or assists with critical safety functions including pre-collision braking, adaptive cruise control, and lane keep assist. Aftermarket glass can introduce optical distortion or variation that can interfere with camera calibration and system performance. Using non-OEM glass in a vehicle designed around camera-based safety systems creates a risk that these features may not function as intended, potentially increasing the likelihood of a crash. This directly impacts federally recognized vehicle safety systems. There appears to be a gap between manufacturer safety requirements and insurance replacement practices. Consumers are being placed in a position where cost-saving measures may override safety-critical specifications. I'm requesting that NHTSA open a formal safety investigation into the use of non-OEM (aftermarket) windshields in vehicles equipped with camera-based ADAS systems. I further request that NHTSA establish clear regulatory guidance or requirements ensuring that windshield replacements follow manufacturer specifications, including the use of OEM glass.

I am submitting this complaint to report a potential safety defect with the windshield glass on my 2025 Subaru Forester. Since purchasing the vehicle in May 2025, I have experienced repeated windshield damage that seems excessive and abnormal for a new vehicle. Within the first two months of ownership, the windshield developed a rock chip. Approximately three months later, I experienced another rock chip that spread into a larger crack when I attempted to have it professionally repaired. Then, approximately two months after that, the windshield developed a large crack that is not repairable and requires full replacement. In total, my windshield has failed three times in less than one year of ownership under normal driving conditions. I have never experienced this frequency or severity of windshield damage with the cars I have owned in the past. This pattern suggests that the windshield glass may be unusually fragile or improperly designed for normal road conditions. The windshield is a critical safety component that supports the vehicle’s structural integrity and ensures proper airbag deployment. Repeated cracking raises serious concerns about occupant safety, visibility while driving, and the vehicle’s crashworthiness. I believe this may indicate a manufacturing or design defect in the windshield glass used in the 2025 Subaru Forester and warrants investigation before more drivers are affected.

A minor rock chip 4 weeks ago resulted in a cracked windshield with spider legs extending from the center point. My insurance carrier (USAA), two glass shops, and the Subaru service center said I should replace the windshield because the crack could extend at any moment without notice. They advised that this could compromise our safety due to obscured vision and the EyeSight system malfunctioning. Subaru parts, and the Subaru Customer Advocate departments, however advise that this part is back-ordered and there is no firm date when it will be available. It could be 6-8 weeks, or an undetermined time frame. I know that windshields are in fact available for I confirmed with Subaru dealers that this model Forester is continued to be produced on the assembly line in Gunma, Japan. All of the new vehicles have of course a windshield. The Subaru Customer Advocate department has refused to find out how to get a windshield shipped from the assembly plant to my dealer. This puts my wife and myself in continuous potential danger should the crack expand/shatter at any time.

The contact owns a 2025 Subaru Forester. The contact stated while driving at an undisclosed speed, the windshield wiper blade speed adjuster failed to function as intended. The contact stated that the wiper blade speed adjuster was set for a slow intermittent speed, however the speed increased. The contact stated that the failure had occurred several times. The dealer was made aware of the failure but provided no assistance. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 1,000.
