Subaru Ascent 2024 — Reported problems

THIS VEHICLE WAS REVERSING, DETECTED AN OBSTACLE AND INSTEAD OF STOPPING, IT ACCELERATED UNCONTROLLABLY AND THEN CAUSED ME TO TRAVELTHROUGH THE FRONT YARD OF MY HOUSE. EVEN THOUGH THE REVERSE AUTOMATIC BRAKING SYSTEM DETECTED THE OBJECT THE VEHICLE CONTINUED TO ACCELERATE. I THEN PUT THE VEHICLE IN DRIVE AND CONTROLLED THE VEHICLE SO IT WOULDN'T HIT ANYONE ON THE STREET OR MY HOUSE. THIS DID CAUSE A COLLISION IN MY FRONT YARD WITH A GAS LAMP POST AND ALMOST CAUSED ME TO HIT MY HOUSE. THIS VEHICLE HAS THE RAB DETECTING SYSTEM THAT FAILED AND CAUSED DAMAGE TO THE VEHICLE.

While driving, shortly after starting the trip (after traveling approximately a quarter mile), I felt what seemed like a bite or an electric shock on my left ankle, at floor level. I immediately pulled over and stopped the vehicle. My sock had a burn/hole in it, and I sustained three distinct marks on my ankle. There were no dashboard warning lights on before, during, or after the incident. This startled me while I was actively driving and could have caused a loss of vehicle control, particularly if it had occurred at higher speed or in traffic. The vehicle has since been inspected twice: once by the selling dealer's service department, and once by the manufacturer's own field specialists, including a full diagnostic scan, a road test, and a physical inspection of interior wiring, including the footwell area near where the incident occurred. Both inspections found no electrical faults, no damaged wiring, and no diagnostic trouble codes related to the concern. The vehicle's Event Data Recorder (airbag control module) was also downloaded and showed no recorded event for the date of the incident. Despite these findings, the cause of the injury has not been identified, and the problem has not been reproduced. I have continued driving the vehicle since and remain concerned this could happen again, since no cause has been confirmed or ruled out. The vehicle is available for further inspection if needed.

I am submitting this complaint regarding the original-equipment Falken ZIEX ZE001 A/S 245/50R20 tires installed on two separate 2024 Subaru Ascents owned by my family. The vehicles were purchased approximately one month apart and are operated under similar New England driving conditions. Both vehicles were equipped with identical factory-installed Falken tires. Beginning at relatively low mileage, both vehicles exhibited substantially similar wet-weather traction concerns, including hydroplaning tendencies and reduced traction during rain. As tread depth decreased, traction in snow, slush, and icy conditions also deteriorated significantly. Both vehicles experienced loss-of-traction events during winter driving conditions, including incidents in which the vehicles slid off the roadway. The concerns were reported to Falken Tire and Subaru of America. Falken advised that the tires were manufactured to Subaru's original-equipment specifications and directed me to Subaru regarding my concerns. One of the vehicles ultimately received replacement tires through a Subaru retailer. The original Falken tires were replaced with General AltiMAX RT45 tires. Following replacement, the concerns were improved. The second vehicle remains equipped with the original Falken tires. At approximately 13,000 miles, the tires measure approximately between 2&3/32 inch tread depth and continue to exhibit the same traction concerns. Because two separate vehicles equipped with the same original-equipment tires have exhibited substantially similar wet-weather and winter-weather traction issues, and because replacement of the tires corrected the concern on one vehicle, I believe this matter warrants review from a vehicle safety perspective.

While pulling up to a drive thru window the vehicle shuddered and the engine shut off. I lost all power steering and had to come to a stop, shift into park, then restart the engine. No check engine lights or warnings illuminated. There were no status messages to indicate what caused it to shut off. Also the driver side mirror shakes a lot, just like all the other reports say.

I am a current lessee of a 2024 Subaru Ascent. I leased this vehicle starting July 27, 2024. My lease ends on July 27, 2027. I live 60 miles away from the dealership and only did a test drive around town. The minute I got on the freeway after leaving the dealership the night I leased the vehicle, I noticed the drivers side mirror heavily vibrated and I remember thinking how strange it was to have the headlights from the cars behind me look so shaky in the mirror. I took the car to the service department on August 9, 2024 where they logged a "driveability diagnostic" and "MPI." My reason for that appointment was the side mirror vibrations. It is bad during the day, but not as noticeable and very distracting when driving at night. I was told by the service member that they were "aware" of this issue and had seen it "a few other times." They "fixed" it but the vibrations continue to this day. I'm filing this complaint now as I have become aware of a class action lawsuit against Subaru for this very issue and I want to document my vehicle as one that was affected and ignored.

While cruising on a 2-lane road or a freeway, the vehicle will cross over the adjacent line, either left or right. This generally happens between 50 to 75 mph. The event happens either when cruise control is on or off. Wind is not necessarily the problem. The solution requires one to take the necessary immediate steering correction. At times, the departure from the lanes may repeat. This may be a temporary correction. This may create a head-on collision if not immediately correctly manually. VERY DISTURBING!

On 9-May, 2026, the vehicle was driven during the morning with no warning lights or indication of component failure. Vehicle was parked on the owner's driveway at approximately 13:00. Approximately 15:40 I started the Ascent’s engine, let it idle for about 60 seconds, buckled up and scanned dashboard and rearview mirror. No warning lights or any fault indication. Approximately 15:42, I put the vehicle in reverse and released the brake Approximately 15:42:30 the vehicle exited the driveway Approximately 15:43 there was a shudder on [XXX] (heading north); the dash lit up with multiple warning lights; the check engine warning illuminated and the ATOIL Temp warning light engaged. At this time, the vehicle rolled down a hill, un-commanded, and only with repeated pumping of the brake did the vehicle stop. Approximately 15:49 I was able to park the vehicle, engaging the hazard flashers and exited the vehicle. While no one was injured in this instance, had this happened on a highway there would have been insurance losses and potential injuries.

The hood acts like it is going to come loose whenever I : 1> Meet a semi-truck on a two lane road. 2> If following a truck on interstate. 3> Driving when windy. The flex in hood is very unnerving for fear it is going to blow off when in traffic. The body shop has adjusted latch today but did not correct the issue.

Uncommanded maximum braking with simultaneous high-voltage and low-voltage shutdown. Vehicle is not safe in Florida with puddles or any types of ongoing obstructions vehicle shuts down in the middle of traffic if it perceives you do not match Google maps

My 2024 Subaru Ascent developed a recurring clunk/thump noise from the steering system during low-speed turning (10–15 mph) and when turning the wheel at a stop. The noise was present daily and worsened over time. I took the vehicle to two Subaru dealerships. Sterling Subaru dismissed the steering noise completely and stated they could not duplicate it. Dulles Subaru also initially dismissed the issue. Only when I returned to pick up the vehicle and insisted on demonstrating the noise did their technician acknowledge it. They compared my vehicle to another Ascent on the lot and confirmed the noise was abnormal. Dulles then replaced the steering gear box assembly (steering rack) under warranty. This confirms there was a mechanical defect in the steering system. Before this repair, I also reported excessive inner-edge wear on both front tires. The technician documented “excessive wear on both front inner tires” and recommended replacing all four tires and performing an alignment. Inner-edge wear on both front tires is not caused by lack of rotation—it is consistent with misalignment or steering geometry deviation, which matches the confirmed steering defect. Subaru America has refused to replace the damaged tires even though the tire manufacturer (Falken) stated in writing that irregular wear caused by a mechanical defect is the vehicle manufacturer’s responsibility. Safety concern: A defective steering rack caused abnormal steering behavior and front-end geometry issues, which led to rapid inner-edge tire wear. If unnoticed, this can result in loss of steering control or a tire failure at highway speeds. Both dealerships initially dismissing the issue is also concerning. I am filing this report so NHTSA can track potential steering-related defects and resulting tire safety issues on the 2024 Subaru Ascent. I can provide service records, photos, and Subaru correspondence upon request.

When driving below 5 mph—forward or reverse—with the rear passenger door fully open, the only alert is a small “door ajar” icon on the dash. This icon is the same drawing, whether the door is completely open or semi-latched, so the driver has no way to know the extent of the hazard. Without an additional warning, an fully open door can strike pedestrians, poles, garage, or other vehicles, and any passenger seated beside it is needlessly exposed to injury.

My vehicle has lost EYESIGHT TOO MANY TIMES while Am driving ON HIGH WAY SO STEERING WHEEL LOCKED, ADATER,CRUISE CONTROL SIGN APPEARS TOGETHER .JUST A SECOND MY FAMILY HAD ALMOST DIED DUE TO VACATION TIME IN AUGUST,2025.I CANT BELIEVE THAT IS BRAND NEW SUBARU ASCENT TOURING 2024 I PURCHASED FROM MARCH ,2024. We found SUBARU DEALERSHIP AT LAS VEGAS ,NA But TECHNICIAN OF THERE RESPONDED TO ME THAT : THEY DONT KNOW EXHAUST BUTTON NUMBER and THEY ARE NOT SURE MY CAR STILL SAFE OR NOT SAFETY WHEN I AM DRIVING ON THE HIGHWAY, (MY FAMILY HAS 7 peoples from [XXX] OLD TO [XXX] OLD ,WE HAD TO SLEEP AT GAS STATION OVER 2 NIGHTS WITH OUT ELECTRONIC,..) THEY ANSWERED TO ME THAT : THEY CAN NOT FIX IT. Their ANSWER MADE ME SCARED BECAUSE WE NEED TO A CAR GO BACK HOME .WE CAN NOT DRIVE IT ANYMORE ,I DECIDED TRADE IT TO CHEVROLET TO PURCHASE OTHER BRAND NEW CAR on AUGHUST 9,2025 TO BACK HOME.

When the passenger cool seat is turned on, a loud vibration like sound can be heard. My assumption would be a fan. I’m unsure if this could lead to any other issues such as electric problems or cause a fire.

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 contact owns a 2024 Subaru Ascent equipped with Falken Tires, Tire Line: ZIEX, Tire Size: 245/50/R20, DOT Number: IRAKH. The contact stated that while driving approximately 10 MPH and attempting to make a turn, the rear tire experienced a blowout. The tires were the original tires. The local dealer was contacted. The vehicle manufacturer was not notified of the failure. The tire manufacturer was not notified of the failure. The failure mileage was 11,200.

The windshield cracked right at the corner of where the defects have taken place on the previous year Ascents, which is not covered under the extended warranty.

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.

Have had two fuel level senders fail in one year of ownership. The dealer/manufacturer has replaced the first one, and a second replacement is pending. The failure shows inaccurate fuel levels including a full tank reading as 1/4 or less full. Subsequent refueling does not change the level reading. If the car thinks it is out of fuel, it may cease to operate (even if there is fuel in the tank).

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)

My 2024 Subaru Ascent started experiencing brake issues in early January. The car would shake heavily and make noise when braking, despite having only 10,500 miles. Concerned, I contacted Subaru of America and was advised to take it to a dealership for an inspection. On 1/31/25, the dealer inspected the brakes and determined that the front rotors and brake pads needed to be replaced. Subaru of America confirmed that the dealer would order new parts for the front brakes. A few days later, I received an email from the dealership stating that the new rotors and brake pads had arrived, and they scheduled me for service on 2/14/25. However, after waiting at the dealership for three hours, I was informed that instead of replacing the rotors as initially promised, they had simply resurfaced them. The explanation given was that these were already “upgraded” rotors. This raises serious concerns for me—if these rotors were already upgraded, why did they fail before 10,000 miles? This is a clear safety issue, and I am increasingly worried that both Subaru of America and the dealership are not properly addressing the situation. I was supposed to receive brand-new rotors, yet I am now left with resurfaced ones, which does not give me confidence in my vehicle’s safety. I need a proper resolution to this issue. Potentially Subaru America should issue a safety recall for these breaks.

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 !

The vehicle was being driven on a public road, going roughly 45mph. I felt a very harsh studder/clunk and completely lost responsiveness from the accelerator. There was no throttle response even pumping the pedal all the way to the floor. I was able to coast to a parking area and make a safe stop. Once I was stopped, I turned the car off, back on again, and it got me the rest of the way home. This was the most severe instance of the problem, but both primary drivers of the car have experienced the accelerator going unresponsive at different times. Since this was a severe safety related concern, we took the car in for service at the dealer, but were told they were unable to reproduce the problem and did not make any repairs. We provided the dealer with a video we captured toward the end of the latest incident, but they haven't been able to find any cause. There were multiple warning lights on the dash, but no codes were stored. We did have another warning light for a brake system error, but there was no code stored and the dealer was unable to located the source of a voltage anomaly in the parking brake system. We've taken it in to another dealer service center for additional diagnostics but the original shop is refusing to provide the complete details of any diagnostics and corrections they have made, so we don't have the original data that was pulled from the car.

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.

The 360 surround view camera system on my Subaru Ascent consistently displays a misaligned, distorted, and altered image of the vehicle's surroundings. Objects in proximity to the vehicle, including nearby cars, curbs, and obstacles, appear shifted from their actual positions, creating a false sense of clearance. This misrepresentation of the vehicle's environment makes it extremely easy to run into objects or curbs that are shown incorrectly in the camera feed. The distortion in the 360 camera’s view compromises the accuracy of its intended purpose, which is to aid in parking and close-quarters maneuvering safely. I have already experienced multiple close calls due to this issue and believe it poses a significant safety risk, especially in tight parking spaces, low visibility conditions, or when relying on the camera for backing up. The feature is marketed as a safety tool, yet its inaccurate display creates a hazard rather than preventing one. I urge the NHTSA to investigate this problem, as it compromises driver safety and can lead to property damage or accidents due to incorrect visual information provided by the vehicle's system. Attempts to Resolve: I have brought this issue to the attention of the Subaru dealership, but they have not provided a solution. The camera system remains misaligned and unreliable. Safety Concerns: The misleading camera display creates a high risk of collisions with objects or pedestrians, especially when backing up or parking in areas with limited space. This poses a serious safety hazard, particularly when drivers rely on the system's accuracy to avoid obstacles.

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 side mirror vibration increases with the speed to a point that it affects the ability to see anything in the mirror.

The driver side mirror vibrates making it unusable to use. Subaru is unable to repair the problem.

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!

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.

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.
