2024 Subaru Ascent — Known Issues & Recalls

Your driver's side mirror vibrates excessively, making it hard to see clearly while driving. Subaru replaced the entire mirror assembly, but the vibration and blurred view continue. The dealer has indicated they're unable to resolve the issue.

Your driver's side mirror vibrates excessively while driving, making it difficult or impossible to see what's reflected in it. Even after the dealership replaced the mirror once, the new one vibrates just as badly. The dealership has indicated this is a known issue without a current fix available.

Your driver's side mirror vibrates excessively while driving, making it difficult to see safely, while your rear view and passenger side mirrors work normally. This problem has occurred since you first got the vehicle. The issue likely involves adjusting or replacing the mirror assembly or its mounting hardware.

Your driver's side mirror vibrates and shimmers at highway speeds and over bumps, making it difficult to see clearly in that mirror. This distorted view creates a safety hazard. Subaru has already replaced the mirror glass and housing, but the vibration persists while your passenger mirror works fine. The fix may involve inspecting the mirror mounting bracket, adjusting the mount alignment, or replacing internal mirror components.

Your driver's side mirror vibrates excessively when driving at highway speeds of 55 mph or higher, making the mirror image blurry and difficult to use for checking the distance and speed of other vehicles. You haven't taken the vehicle in for service yet, but you have an appointment scheduled for your 6,000-mile service in late October. The fix may involve inspecting and adjusting the mirror mounting bracket or replacing the mirror assembly if it's defective.

Your driver's side mirror vibrates excessively when driving on uneven roads or at highway speeds, making it hard to see clearly in the mirror. The problem has persisted since you bought the vehicle in November 2024, and even after the dealer performed the latest Subaru service bulletin repair in August 2025, the vibration continues. The fix may involve inspecting or replacing the mirror mounting bracket, adjustment mechanism, or the mirror assembly itself.

Your driver's side mirror vibrates constantly, making it difficult to see clearly. This problem started when you bought the car new. The vibration appears to be affecting the mirror's stability and your visibility.

Your driver's side mirror vibrates while driving, and becomes nearly unusable at highway speeds. This appears to be a known issue without an available fix from Subaru.

Your driver's side mirror glass vibrates and blurs your vision when you look at it, especially on rough roads at any speed. You've had this repaired under warranty since April 2024, but the problem persists.

Your vehicle's forward collision avoidance system is applying the brakes at maximum force without you pressing the pedal, and the electrical system is shutting down simultaneously. This happens when your car encounters puddles or obstacles on the road, or when it detects a mismatch between your actual route and what Google Maps shows. This creates a dangerous situation in traffic where your vehicle could suddenly brake and lose power.

Your vehicle's EyeSight driver assistance system repeatedly deactivated while driving on the highway, causing the steering wheel to lock and triggering adapter and cruise control warning messages simultaneously. This loss of power steering on the highway created a serious safety risk for your family. The dealership was unable to diagnose or repair the problem and couldn't confirm the vehicle was safe to drive. Resolving this issue will likely require Subaru to perform a complete diagnostic of the EyeSight camera system, steering control module, and related electrical connections.

While driving at 45 mph, your accelerator suddenly became unresponsive with no throttle response even when pressing the pedal to the floor, accompanied by a harsh studder/clunk sensation. You were able to safely coast to a stop, and the problem resolved after restarting the engine, though both drivers have experienced similar accelerator unresponsiveness at different times. The dealer was unable to reproduce the issue or find stored diagnostic codes despite warning lights appearing on the dashboard. Resolving this may require advanced diagnostic testing to identify intermittent throttle control or electronic throttle body issues that aren't triggering stored fault codes.

Your 2024 Subaru Ascent may develop a clunking or thumping noise from the steering system during slow turns or when turning the wheel while stopped. This noise can worsen over time and may indicate a defect in the steering rack that affects wheel alignment, causing abnormal wear on the inner edges of your front tires. If left unaddressed, this steering issue could potentially lead to loss of steering control or tire failure at highway speeds. The fix typically involves replacing the steering rack assembly and having the wheel alignment corrected.

When driving slowly in forward or reverse (below 5 mph) with a rear passenger door fully open, your car only shows a small "door ajar" icon on the dashboard. This icon looks the same whether the door is slightly ajar or completely open, so you can't tell how much danger you're in. A fully open door could hit pedestrians, poles, or other objects, and passengers sitting near it are at risk of injury.

Your rear tire blew out while driving at about 10 mph while turning, even though the tires were original equipment with only 11,200 miles on them. You contacted your local Subaru dealer about the failure. The tire may need to be replaced, and the dealer can inspect whether there was a manufacturing defect or road damage.

Your fuel gauge is showing inaccurate readings, sometimes displaying a full tank as only 1/4 full or less, and the reading doesn't update even after you refuel. This happens because the fuel level sender—the sensor that tells your gauge how much fuel is in the tank—has failed. If your car thinks the tank is empty when it isn't, the engine may shut off while you're driving. The fix will require replacing the fuel level sender unit inside or near your fuel tank.

Your 2024 Subaru Ascent is experiencing heavy shaking and noise when braking at only 10,500 miles. The dealership initially promised to replace the front rotors and brake pads, but instead only resurfaced the rotors after you waited three hours for service. You're concerned that resurfaced rotors won't reliably address the problem, especially since the "upgraded" rotors failed so early in the vehicle's life.

When you turn on the passenger seat cooling feature, you hear a loud vibrating noise that sounds like a fan running. You're concerned whether this noise indicates a problem that could develop into electrical issues or create a fire hazard. The fix would likely involve inspecting or replacing the seat cooling fan motor.

Your windshield cracked at the corner, in the same area where previous model year Ascents have experienced defects. Unfortunately, this damage is not covered under the extended warranty, so you'll need to pay out-of-pocket for repairs. The windshield will likely need to be replaced entirely.

Your driver's side mirror vibrates excessively, sometimes so much that it distorts your view in the mirror. This problem has been present since the vehicle was new, and many other 2024-2025 Subaru Ascent owners have reported the same issue on forums and social media. The fix will likely involve inspecting and tightening the mirror mounting bracket or replacing the mirror assembly.
