2024 SUBARU ASCENT Visibility Problems

Driver's side mirror vibration on uneven road or at highway speeds makes visibility in mirror difficult. This has been the case since purchasing the vehicle in November 2024. Have had most recent Subaru service bulletin on mirror performed by dealer (on 8/8/25), but the problem remains.

The drivers side mirror has a constant vibration that causes visibility issues. Has done it since we bought it new.

Driver's side mirror vibrates when driving. Almost not usable when at highway speeds. Seems like Subaru does not have a fix for it.

Driver side mirror shakes/vibrates excessively sometimes to the point of distorting images seen on the mirror. Many other users are reporting this issue with 2024 and 2025 Subaru Ascents. The issue has been there since the vehicle was purchased brand new. There are threads on reddit, facebook, and the Subaru Ascent forum, where many owners have reported this issue. Below is a link to a thread in the Subaru Ascent online forum. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Driver's side mirror glass vibrating to blur vision when looking to rear at all travel speeds , depends on how rough road is !!!!!!!!! Had warranty work done but problem is not resolved , April 2024 to NOW STILL !

Drivers side mirror vibrates and blurs view. Subaru replaced mirror assembly but the issue persists. Dealer said they can’t fix it

When driving the side mirror on the driver’s side vibrates so much that it impairs the drivers ability to see anything in it. I have had the mirror replaced once and the replacement does the same thing. I was told by the dealership that it is a known issue without a solution.

Driver side mirror shakes so much while driving that it is totally unsafe. Rear view and passenger side mirrors are fine. No vibrations. I have had this problem from day one.

Noted the driver side mirror produces a shimmying image (glass appears to vibrate) at highway speeds and when going over bumps in road at lower speeds. This produces an unsafe vision of items out of the drivers side view mirror. Subaru replaced the glass and it actually got worse. So Subaru replaced the mirror housing on the driver side however the vibrating images are still there. Passenger side view mirror is unaffected. This creates a hazard as the view in the drivers side view mirror is distorted.

Driver's side mirror vibrates at highway speeds 55+ mph, so much so that images in the mirror are blurry and difficult to clearly make out distance and speed of other vehicles. Vehicle has not yet been in for service, but is scheduled at the end of October for the 6K mile service. I'll report it then and see what the dealer says. I've seen that this is reported by other owners without resolution, and now there is also a class action lawsuit filed in TX.

Driver side mirror shakes while driving.

The driver’s side mirror glass has excessive play which causes the mirror to vibrate when under power. The vibration has been present since the vehicle was new and has become incrementally worst. This significantly impacts the ability to clearly see using this mirror. Concern was brought to dealer who stated others vehicles on the lot so the same thing so there is no repair option available.

Driver's side mirror shakes/vibrates at highway speeds and going over small bumps. It makes it difficult to look at while driving.

Driver side mirror shakes whe driving. It's difficult to see with it.

The driver side mirror vibrates, causing the reflection in the driver-side mirror to become distorted and impeding the driver’s ability to observe traffic. My understanding is that there is no remedy. The vehicle has done this since taking delivery in April 2024.

Driver side mirrors shakes badly when speed is over 45 MHP. Many similar issues reported online forum.

The Driver's Door Mirror, has excessive shaking. Bought it to the Subaru dealer where it was purchased, they tried to replace it and the mirror was still shaking. Shop Manager informed me her notified SOA, no fix at this time. Was informed because of slight change to body style and mirror size it has this issue on the 2024 models. It causes the inability to use the mirror clearly on that side of the vehicle. It causes a bit of dizziness for me trying to decipher what I'm looking at. It is a useless but important item on the car for driving. There was no invoice given for the first date of service on 4/01/2024.

The driver’s side mirror vibrates excessively, especially at highway speeds, to the point where it makes me nauseous to use it. I’ve asked my dealer to look at it, and I’ve even upgraded to the night-dimming mirrors, but the vibration still occurs. I am not comfortable using this mirror while driving. I am the original owner, and primary driver, of this vehicle, and it has had this problem since I bought it in April 2024. The car now has more than 14,000 miles on it, and the vibration is starting to affect my driving habits. I’m not using this mirror the way I would under normal circumstances, and it’s just a matter of time until I miss someone in my blind spot due to this issue. Please encourage Subaru to address this problem. Other Ascent owners have complained about this, so I know it is not just an issue with my particular vehicle. Thank you!

Driver side mirror glass shakes constantly at any speed. This has been reported to the only dealership around my area. Mirror was replaced once by Service Dept, but only the mirror housing (not the glass). The mirror shakes the same or worse now. I went back to the dealership within minutes of driving my car off the lot after the replacement and told them the issue was not fixed. I was told to reschedule. I took another day off work to bring the car back to them, only to be told there is nothing else they can do. They keep saying the passenger side mirror shakes too, but it doesn’t- at all. I keep telling them this. This mirror issue presents a huge safety hazard, as it is unreliable and useless to use it. It is also a significant distraction while driving. There were no warnings on the car about this mirror issue. The issue began within a month of purchasing the vehicle in February 2024.

Driver side mirror vibration, per dealer and manufacturer, this is a known issue with no fix released yet

Driver’s side mirror demonstrates excessive shaking as compared to passenger side. Housing has been replaced but no change. Visually difficult for me to use that mirror at times.

In my new 2024 Ascent, there's a vibration in the driver side mirror that gets worse as speed increases. It's a minor issue, but it's disappointing for a brand new car to have this problem. The Subaru dealer hasn't taken any action despite being informed about it, and the vibration persists.

The driver-side mirror vibrates and shakes excessively on rough roads or at highway speeds, making it difficult to use, especially at night. In contrast, the passenger-side mirror is stable at all speeds with minimal to no shaking. The dealer's service department confirmed the problem and replaced the mirror but was unable to fix it, stating that nothing else can be done. The driver-side mirror has had this issue since the car was delivered from the dealer.
