Exterior Rearview Mirror problems of the 2025 Subaru Forester

Driver's side mirror vibrates when driving at highway speeds on freeways; vibration is so bad that it makes the image blurry when using the mirror to change lanes.

The contact owns a 2025 Subaru Forester. The contact stated that while driving approximately 30 mph, the driver's side mirror vibrated abnormally. The failure caused the reflection in the mirror to become distorted. The contact stated that while driving faster than 40 mph, the vibration of the mirror increased. The contact stated that the blind spot warning operated as needed; however, the distortion of the mirror caused visual eye strain while looking into the mirror. The contact had taken the vehicle to a local dealer three times, and the mirror was replaced on the first visit. The vehicle was repaired; however, the vibration reoccurred and was more pronounced. The contact stated that after the last visit to the dealer, a technician wedged two pieces of rubber into the mirror. The vehicle was not repaired, and the failure reoccurred. The manufacturer was informed of the failure and advised the contact that there would be no further action taken. The failure mileage was approximately 4,000.

I have noticed my new suburu driver side mirror shakes during highway speeds and this causes cars and backgrounds to look blurry. I didn't notice this on my other mirrors. It makes it difficult to drive and is distracting.
