The contact owns a 2020 Subaru Ascent. The contact stated that on multiple occasions, while driving at various undisclosed speeds, the vehicle unexpectedly failed to accelerate and lost power. The contact also stated that the vehicle felt sluggish while driving. The vehicle was taken to a dealer, where it was diagnosed with chain slippage in the clutch, causing the loss of power. The contact was informed that the transmission had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure via telephone. The approximate failure mileage was 137,000.

I have experienced problems with the rear lift gate on multiple occasions. It is working intermittently and locking me out. The beeping while the car is in motion is continuous and it drained the battery; I had to purchase a new battery. Another time we had to disconnect the battery (as suggested by the dealership) and reconnect it to fix the problem.

After replacing tires I started hearing noises from rear wheel. I searched online and it appears there is an issue with wheel bearings on several Subaru models (see YOUTUBE video by FIXBOOK dated July 12, 2026). The issue was confirmed by my Subaru dealer on 9/10/2026. Subary wheel bearings prior to 2026 were subject to poor design resulting in premature corrosion, complete failure and possible separation from the under carriage. New Subaru wheel bearing was redesigned in 2026 (part 28473XC00E), but Subaru never recalled the defective wheel bearings in Tribeca, WRX, Forester, Ascent, Outback models sold prior to 2026?

Subaru has a known problem/design with their LED daytime running lamps on the Ascent model. Dealerships are seeing a high failure rate of these LED lights, and it is always with the left side headlamp assembly. The LED strip quits working. In my case my car has about 42,000 miles on it with estimated 1,500 hours of operation. LED lights are designed to last a minimum of 30,000 and up to 100,000 hours. I see these models all the time with their left daytime lamps out. These lamps are provided for safety reasons and to bring visibility to other drivers. Even Subaru dealer's state that this is a known problem and always the left headlight assembly. FYI, the whole assembly needs to be replaced, and the price range is around $1,300.00. I have reached out to Subaru, and they simply state vehicle is out of warranty, and they will not do anything about it. I say this is a known imbedded issue due to engineering, quality control etc. and each delivered vehicle is more than likely going to experience this issue which again I perceive as a safety issue. Again, LED lights are used because of their long-life expectancy. But in Subaru's case, their lights are designed to fail much sooner than one should reasonably expect. Subaru needs to do the right thing and stand behind these faulty lights and return the vehicle to the level of safety it was intended to offer. However, the only way they are possibly going to consider this if the NHTSB gets involved. I have provided a phot of my car show

The contact owns a 2020 Subaru Ascent. The contact stated that while driving at an undisclosed speed, the vehicle was skipping. The failure was recurrent. The contact associated the failure with NHTSA Campaign Number: 21V955000 (Power Train); however, the dealer informed the contact that the recall repair was completed on July 15, 2025. The contact was the vehicle owner on that date and stated that the vehicle was never taken to the dealer for the recall repair. The dealer diagnosed the vehicle with CVT failure and advised that the vehicle was outside warranty coverage. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 145,000.

1. The vehicle is experiencing a transmission malfunction/failure. The dealership was able to replicate the issue and confirm the malfunction, which caused the check engine light to illuminate. The vehicle is currently being evaluated by the dealership, and any failed components should be available for inspection upon request while the vehicle remains in their possession. 2.The transmission malfunction is affecting the vehicle's ability to accelerate, maintain speed, and operate predictably. This creates a potential safety risk when the vehicle loses power or experiences unexpected changes in operation while driving, particularly in traffic or at highway speeds. The concern is heightened because transmission failure can leave the vehicle unable to safely continue operating and can cause collisions with other vehicles on the road. 3.Yes. The dealership was able to reproduce the issue, which caused the check engine light to illuminate and confirmed that there is an active problem requiring further diagnosis/repair. 4.The vehicle has been inspected and evaluated by the Subaru dealership/service center. To my knowledge, it has not been inspected by police or insurance representatives. Subaru of America has reviewed my case and the repair history but has declined assistance with the repair or to open a case. 5.Yes. The dealership was able to reproduce the issue, which caused the check engine light to illuminate. The transmission problem was also associated with operation that prom

The Transmission is slipping on my 2020 Ascent. I had the recall wrk-21 performed in July of 2025. Over the last 6 months the car has been hesitant to go at low speeds and shakes at high speeds. Over the last month the transmission started to slip while accelerating , especially up hill. There would be a grinding noise and RPMs would jump. I took it to the dealer and they confirmed it was the transmission via camera test. I called Subaru of America for goodwill help with the cost knowing that there is a know issue with the transmission. They refused due to the mileage, 121,010. •What component or system failed or malfunctioned, and is it available for inspection upon request? The transmission is slipping •How was your safety or the safety of others put at risk? The car is hesitant to go from a starting position. The car will jerk back and forth when trying accelerate when merging or crossing a road. I am also very concerned of catastrophic failure at high speeds. •Has the problem been reproduced or confirmed by a dealer or independent service center? The dealer has confirmed the transmission is bad via camera teat. •Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Just the dealership •Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No dash lights just the feeling and sounds.

My strut bearings have been replaced several times in the drivers sides, my shock and strut has been replaced twice on the drivers side and now the passenger side is doing the same thing. The dealership tells me that there is nothing wrong but research shows this car has known suspension issues. My passenger side front has a loud metallic grinding sound when turning the wheel in park. I’m told this is the brakes which makes no sense. The car feels like it is on ice or sailing down the road, and the car does not maintain an alignment causing the insides of tires to wear out after 15,000-20,000 miles and need to be replaced.

I am reporting a repeat safety concern involving a 2020 Subaru Ascent. The vehicle was involved in two separate collisions after failing to decelerate as expected following normal brake pedal application. The first incident occurred on January 26, 2026. While approaching a traffic signal, I applied the brakes under normal driving conditions. The vehicle did not slow as expected and struck the rear of another vehicle. Property damage occurred, but no injuries were reported. The second incident occurred on May 5, 2026. While approaching a stop sign at approximately 35 mph, I again applied the brakes under normal driving conditions. The vehicle did not decelerate as expected and entered the intersection, colliding with a vehicle traveling perpendicular to my direction of travel. Both vehicles were towed. No injuries were reported. During both incidents, there were no forward collision warnings, automatic emergency braking interventions, or other alerts observed prior to impact. Following the second collision, the vehicle was inspected by an independent technician. Brake components inspected were found to be within serviceable condition and no evidence of neglect or improper maintenance was noted. During inspection, abnormal brake pedal behavior was observed, including continued downward pedal travel while steady pressure was applied. The technician documented that the reported condition was not consistent with normal braking performance and stated that an intermittent hydraulic

I am submitting this complaint regarding a known exhaust manifold/flex pipe failure affecting my 2020 Subaru Ascent Touring (VIN: [XXX] ). My vehicle was diagnosed by a Subaru dealership with a “broken flex pipe on the header” causing excessive exhaust noise and exhaust leak concerns. Repair estimate was slightly over $2,000. After researching the issue, I discovered numerous reports from other Subaru Ascent owners describing identical failures involving cracked exhaust manifold welds and failed flex pipe sections. Subaru has also issued TSB 09-106-23 involving exhaust manifold weld cracking and redesigned replacement components for this issue. Symptoms began in the low 70,000-mile range and progressively worsened before formal diagnosis at approximately 83,000 miles. This appears to be a widespread defect involving emissions/exhaust components. Many owners online report loud cold-start exhaust noise, cracked manifold welds, failed flex pipe sections, exhaust fumes/smells, and expensive manifold replacement repairs. My concern is both the widespread nature of the defect and Subaru’s handling of complaints regarding the issue. Initially, Subaru denied assistance because the vehicle has a branded title. After documentation was provided showing federally mandated emissions-related coverage/extensions were active for this VIN regardless of title status, the denial basis changed to mileage. After explaining symptoms began prior to the mileage threshold, Subaru then cited lack of d

The pressure sensor coming out of the transmission has failed, and it's pushed transmission fluid throughout the engine harness, transmission harness, the bull harness in the dash and the 02 sensors. All of those have been damaged. The car is now unsafe to drive due to the pressure sensor failing. This information comes directly from the Subaru dealership. There was nothing prior to this that indicated there was a problem. I bought the car from a certified dealership 8 months ago and it was a certified pre owned vehicle.

The contact owns a 2020 Subaru Ascent. The contact stated that while driving on several occasions at various speeds, the steering wheel became loose and then tightened inadvertently. The vehicle was taken to a dealer where the failure could not be replicated. The contact also stated that on several occasions while driving, the vehicle puttered and a grinding noise was heard emanating from the engine compartment. The vehicle was towed to a dealer where it was diagnosed during the first visit to be the transmission module. The vehicle was repaired, but the failure persisted sporadically. The vehicle was taken back to the same dealer on the second visit where it was diagnosed that the transmission needed to be replaced. The vehicle was repaired, but the failures reoccurred approximately 5,000 miles later. The vehicle was taken to the same dealer on the third visit where it was diagnosed that the tie rod end and bushing needed to be replaced. The vehicle was repaired, but the failure persisted. The vehicle was then taken to the same dealer on the fourth visit where the failure could not be replicated. The vehicle towed to the same dealer on a fifth occasion where it was diagnosed that the transmission needed to be replaced. The vehicle was not repaired as of yet. The manufacturer was notified of the failure and a complaint was filed. The failure mileage was approximately 82,000.

In December 2025, I had brake replacement, tire service, and wheel alignment performed at Monro Auto Service located at [XXX] child were traveling on the highway during a winter storm when the brakes began making a loud banging noise. My wife was unable to immediately locate a service location and was forced to continue driving for an extended period in winter storm conditions while in fear for her safety and that of our child. When she was finally able to reach a second Monro location between [XXX] and [XXX] , a technician discovered that one brake caliper bolt was missing entirely and a second was dangerously loose. The vehicle had been driven at highway speeds in a winter storm with an improperly and incompletely assembled brake system for an extended distance before help was found. The second Monro location secured the caliper bolt and confirmed the vehicle safe to continue. The original Fairport location was contacted and their manager acknowledged the issue but has failed to provide any meaningful resolution after nearly four months. In a formal BBB complaint response, Monro Inc. confirmed that the caliper bolt had not been properly secured and acknowledged filing an insurance claim for resulting rim damage — an implicit admission of negligence. I am filing this complaint because an improperly assembled brake system — specifically a missing caliper bolt — represents a serious and potentially fatal safety hazard. If this is a pattern of negligence at Monro locations, oth

My 2020 Subaru Ascent struggles to retain power when accelerating, especially from stopping and especially when the fuel is low. The vehicle stalls or loses some power when trying to accelerate. The check engine light is not on and there is no other indication that there is a problem with the vehicle. I have discussed it thoroughly with my mechanic and we both think it sounds like a fuel pump issue. He looked at the other Subaru recalls and thinks my vehicle should be included in the other Subaru fuel pump recall (NHTSA ID Number: 21V587000). Does my vehicle qualify for this fuel pump recall? Thank you.

Water intrusion occurred inside the vehicle, resulting in extensive mold contamination throughout the interior, including the seats, front and rear carpets, and a child’s car seat. The source of the water intrusion has not been identified. The vehicle was taken to an authorized Subaru retailer, which confirmed in writing that water was present inside the vehicle and that mold was covering interior surfaces, including the child’s car seat. The only diagnostic test performed was a car wash to check for a sunroof leak, which did not replicate the issue. The retailer indicated that further diagnostic work would require significant interior disassembly and cleaning at the owner’s expense before the source of the leak can be determined. The manufacturer was contacted regarding this issue and declined assistance, citing “lack of required maintenance.” The specific maintenance and its relationship to the water intrusion have not been identified, and the source of the leak has not yet been diagnosed. The retailer also stated that technicians would not enter the vehicle due to the extent of the mold contamination. As a result, standard recall repairs have not been performed while the vehicle remains in this condition. A dealership technician also documented in a recorded inspection that water was present beneath the carpet, that the source of the leak could not be identified without further disassembly, and that the extent of mold contamination created an unsafe working environment. Th

I was driving and I got check engine light and all safety features disabled while I was in the freeway, luckily I was able to drive to nearby Subaru dealer for inspection and I found out that there was a recall on the engine for this vehicle and when I contacted the manufacturer they asked me to take it for diagnostics and I did that at a Subaru retailer, but the case manager told me that this recall is being completed for the previous owner of the vehicle and cannot help me with anything, which was never disclosed when I was buying the vehicle.

Vehicle: 2020 Subaru Ascent (Build Date: March 2020) Component: Power Train – Automatic Transmission – Hydraulic Pressure Sensor / Wiring Harness The vehicle developed a flashing "Transmission Service" warning and check engine light. It was inspected by a certified technician at Lithia Reno Subaru. Diagnostic scan identified multiple transmission-related codes including P0137, P0700, P2096, P1867, P0867, P2723, and P0841. The technician documented the root cause as: "Found pressure sensor leaking oil through all harnesses." According to the dealership diagnosis, the transmission hydraulic pressure sensor failed and allowed transmission fluid to migrate into the vehicle's electrical wiring harness system. Fluid traveled through the transmission harness and continued into the bulkhead and engine harnesses, contaminating multiple electrical systems. Due to the extent of contamination, the dealership determined that all three harnesses must be replaced. The repair estimate is approximately $8,933. Transmission fluid entering the wiring harness can disrupt communication between the transmission control system and other powertrain components. This electrical contamination can cause erratic transmission operation or sudden loss of propulsion while the vehicle is in motion, increasing crash risk. Subaru has issued recalls and service bulletins involving CVT transmission and hydraulic pressure sensor failures in earlier Ascent vehicles using the same drivetrain. My March 2020 vehicle

Oil Leak(s) (found cam carriers leaking, front timing cover leaking, oil cooler leaking, upper and lower oil pan leaking. recommend engine reseal). Massive oil leaks found in car due to RTV sealant. Subaru uses RTV silicone sealant (formed-in-place gaskets) instead of traditional rubber gaskets for many sealing surfaces (cam carriers to heads, timing cover, oil pans, etc.). Transmission failure at 37,000miles which needed replacement. In dealership service for 52 days at that time. Transmission symptoms continued after replacement. Car hesitates while accelerating making it dangerous to accelerate to speed needed to merge into traffic. Same transmission symptoms occurring now that were present prior to complete transmission failure in 11/2021 that left me in middle of busy freeway with a disabled car. Subaru not taking transmission symptoms seriously. Continuous brush off from service and Subaru. Car is a lemon. Subaru not standing by product. Oil should not be leaking from every orfice of engine.

Car has 82,000 miles, has been maintained and requires an engine replacement due to 'Sludge'. Reading a lot of forums that indicate this is a common situation with this make and model and likely due to manufacturer's defects.

I have had my lane assist come on by its self a few times, which is very dangerous because it seems to take over and will pull on the steering wheel. I’ve also brought my car back to the dealership a handful of times to have it hooked up to a computer and also someone ride with me because the car will either hesitate to accelerate or stutters and doesn’t seem to want to go when I am between 20-30 miles an hour. Other times when I’m at a light or stop sign it hesitates also. I was told there was nothing wrong with it and they reprogrammed to transmission but it didn’t help at all.

Although the NHTSA form does not include a transmission category, this complaint concerns a critical transmission-related defect in my 2020 Subaru Ascent, which caused oil migration into the wiring harness and contamination of the Engine Control Module (ECM). This complaint concerns a critical transmission-related defect in my 2020 Subaru Ascent. The vehicle has been inoperable since June 2025 due to a failure of the transmission secondary pressure sensor. This failure caused oil to migrate into the wiring harness and ultimately contaminated the Engine Control Module (ECM), rendering the vehicle undrivable. Authorized Subaru dealership Huberger Subaru in Colorado Springs documented the following: - Replacement of the transmission secondary pressure sensor - Replacement of the engine wiring harness - Check engine light returned after repair - Confirmed oil contamination of the ECM Despite repeated repairs and part replacements, the vehicle remains out of service for over seven months, with no confirmed timeline for resolution. Subaru of America has not provided meaningful updates or a clear repair plan, and corporate representatives have failed to respond to emails and phone calls. The extended downtime and lack of repair constitute a safety concern, as the vehicle could fail while in use under certain conditions. Additionally, $400 was improperly withdrawn from my account in July 2025 for rental reimbursement during the warranty repair period and has not been refunded. I am s

I purchased this vehicle from Northwest Chevrolet in McKenna, Wa on [XXX] and they did not disclose to me that there were open recalls prior to my purchase. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Replaced front multi plate transfer clutch at 96,987 miles.

The CVT transmission has failed and been replaced three times despite proper maintenance. Subaru has replaced the transmission multiple times under warranty, but the failure continues to recur. •First CVT replacement at 50,542 miles •Second CVT replacement at 88,175 miles •Third CVT replacement at 92,832 miles This shows repeat failure, not wear-and-tear. It is a safety risk: The vehicle hesitates and loses power intermittently, which creates a safety risk when accelerating or merging into traffic. The most recent replacement is incorrectly listed as pan replacement.

Vehicle: 2020 Subaru Ascent Issue: Cold weather software glitch If you are operating an Ascent or possibly other Subarus with the CVT in temperatures below -20F be certain to have either a small wrench or the appropriate size socket to loosen the ground clamp on the battery ground cable with you so you can employ what I call the magic Windows fix wherin one completely de-powers the system and reboots it. With all the ridiculous interconnections, if the CVT temperature sensor thinks the tranny is too cold the cars operating system looses it mind and goes completely bonkers. Subaru obviously did no cold weather testing. We have had 2 failures in cold weather. It only happens at temperatures well below the-20F range. The first case happened last year while driving after being stopped for a couple of hours. Everything seemed normal and then suddenly several warning lights came on and all of the safety systems and the eyesight system shut down. The car ran and drove, but none of the associated systems would work. No traction control. No cruise control. Several other systems. The only solution was to disconnect the battery and get this rolling computer to reboot. This was a temporary fix as the condition repeated itself although the car was driveable but with none of the safety systems operational. This year we were out in cold weather, -25 to -32. We went to a place to have lunch and when I went to restart the car the app failed to do so. So I put on all my gear and went out to st

The contact owns a 2020 Subaru Ascent. The contact stated that the vehicle was taken to the local dealer for routine service, where it was discovered that the cam carrier was leaking from the engine. While having an oil change, the mechanic informed the contact that there were no further leaks found. There were no warning lights illuminated. After driving and parking the vehicle, there was an abnormal odor of oil coming from the vehicle. The vehicle was taken to the local dealer, where it was diagnosed that an overhaul of the engine was needed. While driving, there was an abnormal oil-burning odor coming from the vehicle. The vehicle was taken to another local dealer, Adventure Subaru (2269 N Henbest Dr, Fayetteville, AR 72704), who confirmed there was no recall coverage for the failure. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 120,000.

Car is making loud noises while going over uneven roads. Only have 64,000 miles on it and I need to replace the struts.

Unknown PCV valve failure caused catastrophic engine failure on interstate highway (70 mph speed limit). Luckily there was room to pull to the side and no one got hurt. This part was recalled in 2019 models due to possible loss of control from engine failure. Dealer tore down engine to determine cause for possible warranty coverage and found the PCV valve was the cause of engine failure. There were no warning lights or indications of any problems before this.

The contact owns a 2020 Subaru Ascent. The contact stated that while driving at an undisclosed speed, there was an abnormal rumbling sound coming from the undercarriage while driving over bumps in the roadway. No warning light was illuminated. The vehicle was taken to an independent mechanic who diagnosed the vehicle and determined that the front struts had failed and needed to be replaced. The contact related the failure to TSB: 059024. The vehicle was not diagnosed. The manufacturer was not made aware of the failure. The failure mileage was unknown.

The contact owns a 2020 Subaru Ascent. The contact stated that while depressing the accelerator pedal to make a turn, the vehicle hesitated to respond. There was no warning light illuminated. The vehicle was taken to the dealer, but was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 61,900.

The driver's side headlamp assembly (one complete piece, LED lighting) has a thin strip at the top that is used for daytime running lights. These are automatically on when the vehicle is on and it's not yet dark. In early 2024, this driver's side thin strip daytime running lights stopped working entirely. I've learned that the entire headlamp assembly must be replaced, rather than being able to just change out the daytime running component or replace a light bulb like one used to be able to do. I've taken the vehicle in for an estimate, and the Nashville, TN Subaru dealership quoted me about $1700 to replace the headlamp assembly, with nearly $1,000 of that being for the light itself, and the rest being labor. The technician at the Subaru dealership was aware of this problem, with many others coming into the shop for the same thing, and he advised complaining directly to Subaru. There are aftermarket options for $200 but the labor is still excessive. From researching online about how to find the aftermarket options, I've learned from a quick google search, lots of posts on Reddit and Facebook, among other forums, of other vehicle owners of this year and the years surrounding it that it is a very frequently-occurring problem, related to it being too close to something in the engine- and others reported that this has happened multiple times to their same vehicle! I called Subaru of America to complain and ask for a Good Will replacement, but they said they would not be able to

My 2020 Subaru Ascent experienced a sudden failure of critical safety systems due to CVT fluid leaking through the transmission pressure switch into multiple electrical components. This fluid leak damaged several wire harnesses and the Engine Control Module (ECM). The check engine light came on and all Eyesight safety features disabled. Subaru has confirmed this will cost over $9,400 to repair. This issue appears to be related to known Subaru Technical Service Bulletins, including TSB 16-103-16R and TSB 02-170-17R, and matches the description in NHTSA Campaign WUV-07. Subaru of America has refused to fully cover the repair, even though my car is well maintained, has only 54,000 miles, and is just 4 months outside the powertrain warranty. This is not normal wear—it’s a serious defect that causes electronic failure and disables safety systems while driving.

The driver front seat bottom frame has came loose and rocks back and forth when driving, especially during start and stops. It was serviced and the dealer stated the movement comes from the side rails of the seat and is referenced via bulletin 12-288-20 stating its a known issue and the frame has been redesigned for this issue. After research, this seems to occur with a number of Subaru models, but the defect has not been covered by Subaru. The movement causes concern if an accident were to occur and should be considered a manufactures defect with replacement being covered by Subaru.

Extreme rattle/clunking driving over bumps especially on dirt roads. Seems to be many people are having this issue. I know of another co worker who has a 2020 ascent making the same noise. Apparently there is a strut issue

Ever since our car went in for re-programing CVT drive chain it progressively has been having a problem of something slipping in drive and in cruise control. feels like a loss of power and a feeling chatter from transmission. Now when you put it in drive it makes a jerking noise. the thing is that we never had this problem until it went in for this recall. it's been back twice and they claim they can't find any problem but continues to get worse. it happens every time we drive it . just returned a 700 mile trip and it's very annoying. Also we do have an extended warranty.

While driving the vehicle between 30 - 40 mph, the vehicle will intermittently studder. I have mentioned this issue multiple times to the dealership and they have attempted to fix the issue but the problem still continues. The issue is occurring more frequently and I’m concerned this may create additional engine/powertrain problems down the road.

When vehicle was 3.5-4 years old, the LED "halo" around the headlight assembly went out. This part is a fixed part of the assembly and unrepairable and requires the owner to replace the entire headlight assembly. An LED headlight should not be going out after only 3.5-4 years. I have noticed this is a common complaint on online forums for the Subaru Ascent. Normally, this would just be a cosmetic nuisance, but in states, such as Virginia where I live, that have annual vehicle safety inspections, the vehicle fails inspection if any part of the headlight does not work, regardless of its effect on the functioning of the actual headlight lamp to produce light when activated. Further, this is a dealer only part and repair and I was quoted $1,300 for an issue that has no effect on the headlight to illuminate the road and is cosmetic only. Subaru needs to address this faulty assembly.

The contact owns a 2020 Subaru Ascent. The contact stated that while operating the vehicle, the transmission malfunctioned, and the vehicle would not properly accelerate. The vehicle was taken to the local dealer who serviced the rear differential but later the failure reoccurred. The vehicle was taken back to the local dealer to be diagnosed, and it was determined that the transmission was faulty and needed to be replaced. The transmission was replaced. No further information was available. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 106,100.

Lug nut studs fail frequently. Have replaced 3. An additional failure identified today during routine tire rotation. Safety issue as wheel can separate from vehicle while driving.

I can’t say what caused the huge crack in the sunroof bc there is no chips on the outside and no chips or breaking point on the inside. We went to get in the car and open up the sunroof and it has a huge crack that is a known issue if you look it up online. So far we haven’t been able to get it fixed bc of the amount of money it cost to have it replaced and it can’t be done by anymore but the dealer as safelight won’t touch sunroofs. It appears that a weak glass was installed and that’s unfortunate too bc they have no intention on fixing this for us.

The contact owns a 2020 Subaru Ascent. The contact stated that while his wife was driving at 55 MPH, the vehicle stalled. No warning lights illuminated. The contact stated that the failure was related to NHTSA Campaign Number: 21V955000 (Power Train). The vehicle was towed to the local dealer where it was diagnosed that the transmission needed to be repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 62,000.

Bolt holding the driveshaft support bracket backed out causing driveshaft to come out. This is a known issue with the 2019 and 2022 Subaru Ascents and have active service advisories but Subaru of America does not recognize it for the 2020 models even know it is also happening in the 2020 vehicles. If the driveshaft would have came out at a high speed it could have caused a crash. Based on the research the bolts do not hold the torque from the factory due to a bolt manufacturing issue and slowly back out after time unknown to the driver. Subaru is not recognizing the problem, so they are not notifying the 2020 owners of the problem, instead they are offering a 50% payment on the repairs as a goodwill payment to offset the cost since it is not a warranty issue. I had had my car in for oil changes in the past and the dealership did not know to check for the tightness of the bolts as there were no service advisories. There should be a recall for this problem before someone dies in a crash caused by this problem.

Driver side window malfunctions intermittently. When raining, slow to go down or up, also skips as it goes up and down.

Component- steering locks Safety risk - vehicle cannot be started. Therefore if in an area of risk - cannot start vehicle. This randomly happens pulling into parking spaces. It is repetitive. I’m older and alone, scary when it happens as you are stranded. And call to Subaru roadside only option was to tow the vehicle the vehicle to dealership. Online fix is to man handle the steering wheel and turn it in the direction of the tension. Pulling into a normal parking space should not create the tension necessary for the steering wheel to lock. I have been on Subaru ascent form us and this seems to be a common problem with this vehicle. Mine has been inspected for the last occurrence and was told battery issue. The other times there were no battery issues and dealerships cannot find issues. Warning light only lights up after steering wheel locks up and vehicle cannot be started. The safety risk for me is being stranded - and no way to prevent it or know when it might happen.

The emergency brake occasionally comes on for no apparent reason. It has happened multiple times before but, never while driving until today. The button appeared to be stuck when I went to disengage it as well which made no sense. There was nothing in the way for it to get stuck. Upon further research in the Subaru forums it appears ours is not the only one to have experienced this. This leads me to believe there may be an unknown issue.

There is a significant crack in the inside rear panel of my panoramic sunroof, and no apparent or visible point of impact. The crack is spreading and needs to be replaced or I fear the glass will shatter. There is no evidence of the crack on the exterior, only on the interior. Car is out of warranty but only has 23K miles and is 4 years old. Took the car to the dealership, and they wanted to charge $4000 to fix. Contacted Subaru of America and they refused to fix. Have been on many Ascent/Subaru forums online and it appears there are multiple complaints about these cracks.

Transmission failure, chugging while driving on the road then slowed down in middle of the intersection, won’t accelerate which is a unsafe situation. It says “check engine”, “break, “eyesight disabled”, “at oil temp” and “transmission”. The speed was stuck to 20mph and engine eas loud. Smelled like something was burning too

Car has 49,700miles. Front drivers side makes terrible rattling noise when driving over any uneven pavement or bumps. Took it to the dealer to determine the issue. They said the entire strut assembly needs replacing. No warning lamps have ever come on related to this issue. I have no idea if the car is safe to drive. There is a national back order on the parts. The dealer wants $1344 to replace it. This is crazy to me. I've driven cars with LOTS more miles than this and have never needed a strut replaced.

A clunky noise coming from the front wheels whenever we encountered any sort of bump.

The battery died after two weeks of replacing it, later revealing the alternator failed. Parts are not available, Subaru kept them My safety was at risk because the lights on my dashboard Christmas Tree'd letting me know something was wrong. Within a couple of blocks I had no power steering and was dying on a busy street. The car was so dead that I couldn't even turn on my hazard lights. The car was jumped by Subaru, the tow truck driver left and the car died two blocks later. This time in the middle of the busy street. The vehicle was towed to Subaru who replaced the battery we bought two weeks earlier. We asked if they check the charging system and they said yes. The battery light was on before we left the lot. We made them keep the car so we wouldn't die in the middle of anymore busy streets. Days later they determined it was the alternator. The car had 26,000 miles on it. I don't know what Subaru did with the parts. They said they needed them as it was a warranty replacement. The battery light never came on before the car died. First the Eye Sight Disabled light came on then many lights on the dashboard flashed on. This happened a couple blocks prior to me losing power. I found the first place I could to get off the road. Two weeks prior when the battery died, the eyesight disabled light came on and the battery light. That time I got home and we replaced the battery. Therefore when the eyesight disabled light came on, I knew something was wrong but thought I had time to g
