2019 SUBARU ASCENT Safety Overview

Component: POWER TRAIN

"The vehicle has 178k miles on it currently. I had to have a transmission and transfer case replaced at 68k miles. Done by Subaru. At 168k miles I had to have a new front pump in the transmission case replaced. Repair done by Subaru. Now at 178k miles the second replacement transmission has completely failed and needs replaced."

"Immediately after pushing the lift gate release button on the dash, a loud and constant alarm tone began. The gate would then not open using the button on the dash, remote, or handle on the exterior of the lift gate door. To access the items in the rear (and to stop the alarm), we needed to get the door open. We followed the owner's manual exactly to access the internal emergency release. We removed the plastic cover for the gear unit, then used a screwdriver to manually move the release to the right. Despite every amount of pressure we tried, including adding pressure by pushing down on the gate from the outside with one person while another tried the release procedure, the gate would not open. We ended up looking on YouTube, and found a video that this is not uncommon - and that the solution is to disconnect the battery or to remove fuse #14 on the fuse panel. With tremendous effort and using a pair of pliers, we finally removed the fuse. The alarm stopped but the gate (and other parts of the electrical system) were now off. We replaced the fuse and the door returned to normal function and opened using the handle on the lift gate. This is a tremendous safety issue. First, there is no easy way to open the gate manually from the interior in the case of an emergency (removing the safety cover and the use of a screwdriver or similar tool is required). Second, this emergency process failed completely, as the gate couldn't be opened at all using the manual release."

"My 2019 Subaru Ascent Limited had a safety recall that was related to a CVT transmission issue. That safety recall was addressed by Sewell Subaru (Dallas, TX) in January of 2025. This past Wednesday, July 29, I was driving on a state highway on my way to work from my residence. Not even two miles away from my residence, I felt a jerk and a loud "thud". That was followed by loss of power in that the vehicle just was rolling, but no power from the gas. I was able to safely maneuver onto a the shoulder and stop the vehicle. Within minutes, I noticed a puddling of a large amount of fluid that I could easily recognize was not oil. The vehicle was towed back to Sewell Subaru this past Saturday and I was notified today that the CVT belt snapped and it caused a hold in the transmission case, which caused the fluid to leak. The service advisor also mentioned that Subaru is not wanting to cover the replacement and that they are citing that the reason is that Subaru records are showing irregular servicing done by a Subaru service center. This issue has nothing to do with routine maintenance, or where I get those, and has everything to do with the catastrophic failure of the very same component that was at the heart of their known safety recall issue."

"All the safety systems become disabled and check Engine light goes on because transmission fluid is being pumped Out of a faulty secondary pressure sensor part 31878aa020,( defective and replaced with 31878aa021), into the engines wiring at the car computer, transmission computer, and bulkhead connector in fuse box causing all sorts of engine codes. The setting of the engine code closes all the vehicles driver safety systems and changes the dynamic of the drivers driving experience. As the problem gets worse, it can render the car powerless on roads and highways making operation dangerous. I have my car parked in front of the house with the battery and electrical connectors unplugged. This problem is covered by one or more recalls and safety campaigns, but subaru refuses to fix mine and other peoples that I found on Facebook. Someone online listed a $6500.00 repair estimate. They just had it repossessed instead. This part causes the pressure differences that cause the jerky ride and is specifically alluded to in the recall, plus subaru even changed the part because it was defective."

"NHTSA Vehicle Safety Complaint Vehicle: 2019 Subaru Ascent VIN: [XXX] Mileage: 72,093 miles I am submitting this complaint because my 2019 Subaru Ascent experienced a serious transmission-related electrical failure that may represent a broader safety defect. Sewell Subaru of Dallas diagnosed an internal failure of a transmission pressure sensor. According to the dealership’s written report, the failed pressure sensor allowed transmission fluid to leak into the electrical wiring harness. The transmission fluid then migrated through the wiring and into the bulkhead harness. The dealership advised that the fluid contamination had affected multiple parts of the vehicle’s electrical system and recommended replacement of the transmission wiring harness, engine wiring harness, bulkhead harness, Engine Control Module (ECM), Transmission Control Module (TCM), and related components. Because the wiring harnesses are routed throughout the engine compartment and vehicle, the repair also requires extensive disassembly of the vehicle, including disconnecting and removing numerous engine compartment components to access and replace the contaminated harnesses. The estimated repair cost was approximately $12,000. I also have video documentation of the dealership technician performing the inspection and explaining the transmission fluid contamination and migration through the wiring system. I am willing to provide the video, the dealership's written diagnosis, repair estimate, photographs, and any additional supporting documentation upon request. My vehicle falls within the published VIN range associated with Subaru recall WUV-07, which involved the CVT hydraulic pressure sensor harness and transmission hydraulic pressure system. That recall was later superseded by WRK-21. I understand that the published recall addresses electrical resistance and transmission hydraulic pressure readings rather than transmission fluid leakage.

"Noticed my car shifting incorrectly since 66,000 miles. At approximately 68,800 miles transmission begin to fail. At a stop sign I pulled out before oncoming traffic with what should have been plenty of time, but transmission failed. It seemed to have had chain slip; completely stopping the car when I was in oncoming traffic. I put the pedal to the floor it caught, and whipped me around the corner. After that it was doing the same thing consistently until I parked it at my residence."

Component: AIR BAGS,ENGINE

"The contact owns a 2019 Subaru Ascent. The contact stated that while his wife was driving at approximately 75 MPH, a deer ran across the highway and hit the left driver's side of the vehicle. The air bags did not deploy upon impact. A grayish smoke began to emit from the vehicle as the contact's wife immediately pulled off to the side of the road. Due to the damaged cause by the impact of the deer, the contact's wife had difficulty exiting the vehicle. The contact's wife used excessive force to open a crack in the door, which was enough to slide herself out of the vehicle. The vehicle became engulfed in flames soon after exiting the vehicle, and the authorities were called to the scene. The fire department arrived at the scene and managed to extinguish the fire. The contact's wife sustained bruising to her left shoulder, left leg, and left arm but did not seek medical attention. A police report was filed. The vehicle was initially towed to an independent tow yard and was later towed to an insurance holding facility. The contact stated that the vehicle was destroyed as a result of the fire, but the insurance adjuster had yet to determine a final ruling on the vehicle. Neither the dealer nor the manufacturer had yet been notified of the failure. The failure mileage was unknown."

"Component/System Failed: The vehicle’s CVT transmission and related transmission components. The transmission and associated components have been replaced multiple times by authorized Subaru dealerships. The vehicle is available for inspection upon request. Description of the Failure and Safety Risk: The vehicle has experienced repeated, intermittent transmission malfunctions, including warning lights, loss of power during acceleration, and sudden harsh re-engagement. Most recently, while accelerating through an intersection from a stop, the vehicle briefly lost power and then abruptly surged forward, causing a pronounced lurch strong enough to chirp the tires. This created a serious safety concern. A hesitation or loss of motive power in an active intersection exposes me to potential cross-traffic collisions, while the sudden re-engagement creates unpredictable acceleration and possible loss of control. The intermittent nature of the malfunction makes it impossible to anticipate when it will occur. Dealer/Manufacturer Involvement: The issue has been reported to and inspected by authorized Subaru dealerships multiple times. Because the malfunction is intermittent, dealers have stated they cannot fully diagnose the issue unless warning lights are active at the time of inspection. Subaru corporate customer advocacy has been involved in reviewing the case. Warning Lamps / Prior Symptoms: Intermittent transmission and check engine warning lights have appeared repeatedly over several months. The lights often illuminate while driving and then turn off after restarting the vehicle, despite the underlying issue not being resolved."

Component: POWER TRAIN

"Over the past few months the transmission has started randomly refusing to engage. When entering the expressway, you will press the accelerator, and the engine will rev and the vehicle will not accelerate at all. Then you let off the accelerator, let the engine RPM drop back down to idle, and press again and it will accelerate. This has happened 3 times in 2 months. Subaru is refusing to replace the transmission because their tech cannot personally reproduce the problem on demand, even though they have voluntarily extended the warranty on this model transmission due to slippage issues. They are instead going to change the transmission fluid, which has less than 1/2 the mileage for a typical fluid service, to mask the issue, risking the safety of passengers."

"The break pads had to be renewed after 2.5 months because the ABS was engaging every time I used the breaks. At all speeds. 84,000 miles"

"The battery is draining so quick that the car doesnt start at all. The battery drained completely in 3 days and it’s happening more often."

Component: SERVICE BRAKES

"Replaced rear brakes and rotors in August 2025. By may 2026 they had worn down to the metal and needed replaced again. Only had 13000 miles on them. After multiple diagnostics testing was done, no issues were found with the brake system. Monitoring new pads and rotors. Still wearing rapidly but even. After only 6 weeks, they have reached about half of their life."

"All of a sudden my vehicle accelerated after placing it in reverse with my foot on the brake. There was a screeching sound and I immediately shifted into (at least) Park. In attempting to exit my garage again, it repeated the same events. I parked the car and never did leave my residence. No dash lights etc. I am afraid to now drive this vehicle. This occurred several days before this mentioned event, but responded OK the 2nd time. In May of 2025 I actually crashed into a car across the street from this happening. Others are definately at risk. This actually occured twice during my 1st year of ownership, but was overlooked until now. I intend to take it to my dealer and have my vehicle inspected. There were no warning lamps etc."

"As a veteran and spouse of an active duty service member, we are currently fulfiling our overseas tour in South Korea. We were notified of the recall of our Subaru Ascent and made contact with Subaru via email for guidance on how to proceed as we are not within the continental United States. My email to them was as follows: Our family is currently stationed overseas in South Korea. Our family has been stationed here the past two years and will be completing an additional duty of two more years here in service of our country. I previously contacted Subaru addressing the concern of the Recall for our PTC Heater Ground Bolt which has been found to be unsafe and can lead to the vehicle catching on fire. It was disheartening to be told we could not be offered assistance as Subaru only services those in the U.S. Subaru prides itself as providing one of the safest vehicles for families on the market which is why we chose Subaru. What can be done to assist us? I look forward to hearing back soon.  Subaru responded with: Thank you for reaching out to Subaru of America. Regrettably Since we do not have a reciprocal agreement with Korea we would not be able to assist with the repairs until you return to the states. I do apologize as there would be no other loopholes that we will be able to provide to have the repair done. If fyou have any further questions, you can always give us a call back or email back in as well. Hope you have a good day ahead. We will not be able to ship our vehicle until all recalls have been fixed especially as this specific recall does come with a noted safety risk by Subaru and is as follows: This potential condition may result in the melting of the ground terminal and surrounding components when the PTC heater is in operation, increasing the risk of a fire. I am submitting a claim to acquire assistance as to how to proceed. -thank you."

"While driving on the highway, my vehicle suddenly lost the ability to accelerate—this is the second time this has happened, with the first incident occurring in June 2022. Each time I bring the car to the dealership, I’m told that because the issue cannot be recreated on the spot, despite codes that are warranted for the QMR to be done they’re unable to inspect or apply the WRK-21 procedure to replace the transmission under warranty. Despite this, my car consistently slips during normal driving conditions. It shudders and surges unpredictably while accelerating in traffic, creating an extremely unsafe situation. Most recently, I was driving with my children when the car failed to accelerate as I attempted to merge across four lanes of highway traffic. I had to coast until I could safely pull over. On other occasions, the vehicle has jolted forward unexpectedly, nearly causing collisions and forcing me to slam on the brakes. This issue is not only recurring—it is dangerous. I am requesting that it be taken seriously and addressed appropriately under warranty."

"We have been dealing with issues with this vehicle since 2024. We had 3 open recalls which we took into the closest dealership to us and things were okay for a few months and then started having issues again. We live in a small town and it is hard to get to the dealership so we had a few local mechanics take a look and one had found that the exhuast recall was not installed properly and so he addressed that issue. Things were then okay for a little bit after that and then we started having bigger issues the car would not exceed 30 MPH in the middle of us driving and then the car would jerk back and forth. After advice from Subaru of America we got it checked out at a dealership who put a part into the vehicle and then we got it back and less than a week later the car was doing the same things. We took it back and they kept the car for 2 weeks but told us they could not duplicate the problem so we got the car back and right away had the same issues when taking it home. The CVT is for sure messing up we believe and now the car does not drive at all. After some back and forth we found out that the 1st owners took it in for the CVT recall so I reached out to the dealership who did that and was told that they did look at it but at the time the CVT was not an issue but the mileage was fairly low at that time. Personally I am not in a place to afford to get it replaced on my own but I do not believe that the recall should have been closed out knowing that the part would eventually go out since it is a known issue on that car I have tried to go back and forth to get this resolved but I am not getting anywhere and I am not sure what to do at this point to try and get the problems address and made right."

"I purchased the car brand new in 2019. Shortly after purchasing, the transmission started having hesitation and slipping. I took the car back to the Subaru, and they replaced the transmission under warranty. Unfortunately, they replaced it with another full transmission, and very shortly there after, they had to replace it again. Unfortunately, they replaced it with another faulty transmission and now it is at 150,000 miles and needs another transmission. No one offered me to buy back my car with a second transmission replacement. I was told I was trying to scam a new transmission from Subaru. For this third transmission, I had it verified by an independent shop. I have placed a complaint with Subaru and ask them to buy back my vehicle and I have been told it’s unlikely to happen. I am worried about what will happen when the transmission goes out while I’m driving 70 miles an hour down the highway. This is a pattern in the warrants consumer protection. Many other car companies have stopped. Trying to make this CVT because it kept having problems.."

"The contact owns a 2019 Subaru Ascent. The contact stated that while the engine was idling, exhaust fumes entered the cabin of the vehicle. Additionally, immediately after starting the vehicle, there was a loud ticking sound coming from the exhaust system. The vehicle was inspected by the local dealer, and it was determined that the exhaust manifold lines were faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was 120,000."

Component: FORWARD COLLISION AVOIDANCE

"I leased a 2019 Subaru Ascent (VIN: [XXX] ), which is equipped with the EyeSight driver-assist system. In the Spring of 2019, while driving in a parking lot at night with low visibility and snow, the vehicle struck a pole. Despite the imminent collision, the EyeSight system failed to engage Pre-Collision Braking or provide any audible/visual warning to alert me of the obstacle. The system did not disengage or indicate it was unavailable due to weather; it simply failed to function, resulting in a collision. Following this incident, I immediately contacted Subaru of America to report the failure. At that time, Subaru representatives denied any defect existed and stated the system was not at fault. I have recently learned that this vehicle is part of the [XXX], et al. v. Subaru of America, Inc. class action 9[XXX]), which addresses defects in the Pre-Collision Braking and Lane Keep Assist systems. Crucially, I was never notified of this class action or the associated defect by Subaru. I received no mail, email, or other communication alerting me to this safety risk or my eligibility for repair/reimbursement. I only discovered this information via a third-party news source after the settlement claim deadline of September 27, 2025, had passed. Upon contacting the Settlement Administrator and Subaru of America in January 2026, I was told that because the administrative deadline has passed, no remedy is available. Subaru is effectively refusing to address a known safety defect on a confirmed affected VIN solely due to a missed deadline that I was never informed of. I am filing this complaint to document the failure of the EyeSight system and Subaru’s failure to properly notify lessees/owners of known safety defects.
