Data synced from NHTSA on May 4, 2026
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.
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.
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.
Transmission belt broke while driving resulting in a catastrophic failure.
I have a 2019 Subaru Ascent Limited model with 96,xxx miles as of January 2025. In 2023, there was a safety recall for the PTC heater ground bolt sent first class mail for multiple year Ascent models. This recall was completed by local subaru dealership on 3/27/2023 stating "WRL 22 completed. Removed ground bolts and cleaned threads. Found no signs of heat damage. Removed and replaced bolts." Move forward to Saturday, [XXX]. I remote started vehicle from inside the house while on vacation in Bristol Tennesee. Car was running for roughly 5 minutes, when fire alarms inside the house starting going off. Seemed odd considering nothing was going on inside. Walked inside to see large amounts of white smoke coming from the windows of the Ascent. I was able to jump into the car and turn the engine off. I opened all 4 doors to let the car air out. I checked the engine, nothing seemed off. I then turned my attention to the air cabin filter, everything seemed normal as well. After the engine cooled and aired out, there is smoke damage to the vehicle. I was able to transport the car safely to Wallace Subaru which was less than 0.25 mile from our airbnb. I was quickly notified by the service technician that the car is not safe to drive until it was fixed. After further investigation, it was found that the PTC ground bolt has failed again, and this time melting the wiring harness and bolt around it. This was right next to the carpet and put my life as well as my wife, who is [XXX] and my [XXX] daughter. Thankfully we weren't in the vehicle when this occurred. There was no warning. No check engine light, nothing. No other issues leading into the incident. Car is still parked in Bristol TN at the dealership and I am 5 hours away in Lexington KY. Subaru has been uncooperative with this situation and is avoiding talking to me or making this situation better. I literally have no answers.

STARTED THE VEHICLE TO DRIVE 30 MILES FOR AN APPOINTMENT. WHILE DRIVING, ALL OF THE INTRUMENT CLUSTER LIGHTS ILLUMINATED. THE EYE SIGHT TURNED OFF, CRUISE CONTROL NO LONGER WORKED, PARKING BRAKE LIGHT WAS ILLUMINATED, ABS LIGHT WAS ILLUMINATED. TPMS LIGHT WAS ILLUMINATED. THIS HAS OCCURED 2 TIMES BEFORE. THE FIX FOR THE PREVIOUS ISSUES WAS TO CLEAN THE BATTERY TERMINALS.
When trying to maintain highway speeds (65 to 70 MPH) and driving in mountainous terrain of Pennsylvania, Maryland, or New York, the vehicle will shudder as if it is loosing power. The vehicle will rapidly loose speed. No warning code is issued. The only way to solve issue is depress the pedal to increase the RPMs. Took vehicle to dealer and reported that it felt as if the CVT chain was slipping. They said they could not recreate and there was no code.
Subaru windshild in my 2019 Ascent have been replaced twice in 30,000 miles due to very inadequate glass. I'm struggling to get Subaru to acknowledge their responsibility to replace this current cracked windshield with a new part, as per my reading of a settlement that they should be following [XXX] ). They are currently trying to send me to a 3rd party repair business to do the repair, but supposedly they have fixed the part on more recent versions of the car. By comparison, I had a Toyota Highlander for 11 years and never once had to replace the windshield glass. Yes, it took a beating, but never once cracked like this glass does. It's not up to the task, and clearly dangerous. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
We have had to replace battery twice and had to have auto club give us a jump start multiple times. We drive this vehicle once or twice a month, but something is causing battery to run down way to fast. Manufacturer claims we need to drive more often. I have always had one car, that burned to much fuel, and was used as an occasional vehicle, but never had this type of problem. Something needs to be provided so that battery does not leak power when it is a low use car. I don’t want the internal lights to turn on when I walk by, or for it to access the internet. I believe that this leaves us vulnerable to non-availability at a critical time. We are planning a multi-week trip and have no idea if car will start when we return. Nor is their a way to disconnect unneeded activity that is draining battery.
My Ascent is primarily driven in the city of San Francisco, a fairly hilly city. We have had issues with the suspension on this vehicle in the past, and I will need to install my third pair of struts in the coming weeks (the parts are currently on backorder). The CVT has also been replaced on the vehicle. The tires are routinely rotated, and we keep up with the maintenance schedule. We were driving home after dropping our daughters at school and while accelerating up a hill heard a crack. We immediately pulled over, and saw that the lower control arm had sheared.
The CVT experienced a catastrophic failure, later identified as "the chain" by a Subaru dealer mechanic. The night before the incident, the transmission "slipped" and made a metallic clunking noise when merging onto a highway. On the day of the incident, the transmission failed completely after turning onto a roadway from a stop sign. No forward or reverse power was available. Had the transmission failed the night before while merging onto a highway, with little ability to pull out of the roadway, we certainly would have been in danger. The vehicle has been inspected by the dealer and the transmission failure confirmed. The transmission "stuttered" for several months previously while accelerating, though not consistently.
While driving on a road with a lot of hills our car sudden lost all engine power but all of the lights and engine were still on. We pulled over but kept the car on and it seem to resume power. Then about 1/8 of a mile later it happened again. We shut the car off completely for 5 minutes and turned it back on and we were able to drive it normally for another mile. It then happened three more times on our way to a safe spot to pull over. The fifth time it happened all warning lights on the dashboard turned on (see picture). The speed in which it happened varied. It is important to note that we brought it in for service on 8/8 for a standard interval service at a Subaru dealership and have brought our car in multiple times to address issues with the transmission.
There is a knocking or clunking noise at low speeds during and after turning in the front driver's side of the vehicle. Car has 17,500 miles on it. Assembled inspection suggests that tie rod (inner and outer), ball joint, stabilizer links are all intact and functioning properly. No loose components or fasteners. All bushings appear firm and intact. There is an apparent [XXX] ), though seemingly unreported issue with the front-end suspension system that dealerships and service techs can't seem to diagnose. At best, noises go away for a period of time then return. If it's an issue with a wear component then it may be that the OEM parts are deficient for use on this vehicle.

Purchase the car two weeks ago the first night on the way home it was acting up just like it did when I test drove it and was told by the BMW dealership Aristocrat Motors in Topeka Kansas that they would fix anything that was wrong with it. On the way home I realized I didn't think it would make it back the 60 miles so I took it to Olathe Subaru they informed me that it had had transmission problems reported by the previous owners but their technician couldn't get it to do it again so the people just traded it in instead and then I got the car without them getting the transmission fixed or whatever was wrong. They are actually waiting on Subaru of America to respond to tell them what needs to be done to the car and in the process I have been two weeks with little information of what's going on. I feel the recall should have been done and the car is still a good car it just needs to be repaired correctly. Thank you for your response I look forward to hearing from you please help.
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.
The contact owns a 2019 Subaru Ascent. The contact stated that while the vehicle was stopped and attempting to accelerate on several occasions, the vehicle jolted forward while shifting from 1st to 2nd gear. The vehicle was taken to the dealer where it was diagnosed that the computer software needed to be updated. The software updated but the failure reoccurred after almost two months. The vehicle was taken to the dealer where it was diagnosed that another software needed to be updated; however, the failure reoccurred after almost two months. The contact believed that the failure was associated with Manufacturer Recall Number: 16-139-22 CVT Assembly (WRK-21) Warranty Extension (TCM reprogramming to prevent CVT chain slip). The manufacturer was notified of the failure. The failure mileage was approximately 106,000.
Over the course of 5 years, a lot has been mechanically wrong with our vehicle. Each service appointment yielded a 'cannot duplicate' response. Recently, my car has been in the service department a few times. My car had recall work performed on a ground bolt, and my husband advised them that the car had a 'rich fuel' smell when starting with the hood open. I've complained since 2021 of a smell when pulling up the mountain. The smell is what I described as a perm solution smell. Each time, the response was 'cannot duplicate.' In February, I took the car in to have the exhaust inspected because it was getting louder each passing day. I was advised that the entire exhaust needed to be replaced, and I would be responsible for costs. I brought my car home, unrepaired, and called Subaru of America to file a claim through them. I had repeatedly expressed concerns, and nothing was done, yet I'm expected to foot the bill now. Since February 12th, I have been back and forth with Subaru and just made the appointment to get the exhaust work completed, with a small contribution from Subaru. However, this past Saturday, [XXX] my vehicle caught on fire while driving. I am fine, but my vehicle has now been deemed a total loss. As I was descending the mountain, I smelled the same 'perm solution' smell, and shortly after, there was smoke coming from under the hood. The smoke entered the cabin as I pulled off the road. Upon exiting the vehicle, flames and smoke were visible from the hood. I grabbed my purse and ran, called 911, and watched my vehicle engulfed in flames.

Upon starting the vehicle, the driver side mirror started smoking. Secured the vehicle and disconnected the battery. Removed the mirror assembly and notice the electrical wires powering the blind spot indicator of the mirror assembly was burned and melted. Picture of the damage was taken prior to removing the mirror assembly from the vehicle.
The front suspension is making a clanking noise. Inspection of the front strut towers tops shows an interior separation of the rubber in the Strut bearing at 63k miles. There is also a noticeable difference between the left and right side relative to the components present. The space at the drivers side which is making the noise has a bigger separation in its components when the wheels are in a straight ahead position. The failure of this component can cause a catastrophic accident.
The Y pipe that connects the exhaust from the engine to the turbo charger, has cracks from poor welds. It happened 8-12 months ago we started to notice that during warm up our Ascent would sound real loud then quiet down once it warmed up. We didn’t know there was an issue as there were no lights that came on and we had no loss of power or MPG. The safety issue would be that we finally took the car in once we started to smell exhaust fumes coming from the car that we would start to smell from inside the car. We had to start to air out the car after warming up if we couldn’t immediately drive away once started. We contacted Subaru and they offered a partial credit for a repair but after researching I have seen they have had recalls in the past regarding similar cracked Exhaust manifolds on another model car.
Car battery died in store parking lot. Low mileage (24,000). I do lots of short trips and this is a reported problem for 2019 Subaru Ascents. I had to wait 2 hours for someone to bring a charger to drive to auto parts store fire replacement battery.
Battery keeps dying.
During an inspection at the dealership in December 2023, the tech found the oil pan to be leaking. It was resealed during the same visit. Approximately 8 months later, the same problem was found again at the dealership. It was again resealed. Upon further research, this appears to be a recurring problem on similar vehicles.
The contact owns a 2019 Subaru Ascent. The contact stated while driving 70 MPH, the hood was flapping up and down. The contact was concerned that the hood might release and crash into the front windshield. The brake pedal was depressed but was slow to respond. The TPMS warning light was illuminated. The contact stated that the interior lights were inoperable. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure. The vehicle was not repaired. The contact stated that the vehicle was previously taken to the same dealer for routine maintenance, and the brake fluid and coolant were not topped off. The manufacturer was not contacted. The failure mileage was approximately 79,000.
2019 Subaru Ascent was taken to mechanic due to jolting between 1000RPM and 1500RPM. Car was not throwing any code. Mechanics then did other test and it was determined the transmission is failing. Car only has 70,000 miles on it. Also, when car is started at times, there is a very prominent cloud of smoke that comes from the exhaust.
Yesterday I got in my vehicle first thing in the morning and there was a crack at the bottom of my windshield. I’m not parked anywhere near anything that could’ve caused a crack, so it appears to have just randomly cracked for no reason. This morning as I’m just sitting at the bus stop with my kid the crack got a little bigger.
Clouds of smoke at startup scince car was new.
The right front wheel was making an airplane type noise. Upon taking it to Belle Tire in Gaylord, MI, they confirmed it was a defective bearing When the mechanic pulled the wheel off, the CV Shaft pulled apart. It had to be replaced. I have a picture and invoice.
I have been asking Subaru to fix the transmission for 2 years now. It seems like it’s going to stall between 20-25 mph and 45-50 mph. There is a torque converter shutter but I’m told that the car is fine. Subaru corporate has 2 case files for this issue now.
The radio started turning on and off repeatedly and does not work. The back door will not open using any of the buttons.
My 2019 Subaru Ascent windshield cracked from no apparent reason while driving on freeway. There was a loud bang sound and there is a circular crack quite symmetrical in the middle of the windshield. The diameter of the circular crack was ~2 inches wide. There is no hairline fracture. In recollection, it didn't feel like there was any rock or particle that ricocheted off the windshield. It felt more like it cracked on its own.
Battery draining problem
Arrived at my car after traveling for the weekend, and arrived to my car to find out the battery was dead. Nothing on, lights were in Auto like normal. The last thing I did after getting out of my SUV was grabbed my suitcase from the trunk. I think it must not of latched correctly and it drained the battery. There is supposed to be a light delay to preserve the battery but it did not work in this case. I still can't open the trunk. This happened once before while camping with our dogs we left the tailgate up to unpack and pack the SUV. We loaded the dogs up to leave the campsite. When we went to start the SUV the battery was dead. Seems leaving the tailgate open drains the battery. The problem is even after we got our car jumped and the car was operating okay, we could not open the tailgate. It just makes a beeping sound like it wants to release but will not open. The manual handle should allow anyone to open the gate even if there is a electrical disturbance. This is a safety issue related to not being able to get our dogs out of the cargo compartment. Our dogs are over 100 lbs and their travel crates are large and need to be opened from the rear of the vehicle.
Oily blue smoke from exhaust upon start
Vehicle has completed all transmission recalls. Until recently, Subaru continued to say that the issues I was experience with loss of power or glitchy shifting could not be duplicated. After the vehicle exceeded it's warranty coverage, they were suddenly able to duplicate the problem and say that the CVT was causing my problems, that reprogramming failed and that the vehicle needs a new transmission. These issues have persisted before and after the recalls related to the CVT and have cause two near accidents as I pulled out into traffic only to have the car not shift/accelerate as expected. I no longer allow my teenagers to drive the vehicle due to this safety concern. I firmly believe the prior recalls were not effective in resolving the issues with the CVT and/or that Subaru said no damage to the chain was visible and checked the recall as done without actually doing anything more than reprogramming. I believe the issues should be looked into further and coverage for the CVT should be extended beyond the initial reprogramming provided by the recall.
The contact owns a 2019 Subaru Ascent. The contact stated that while driving at approximately 70 MPH, the vehicle stalled. The vehicle was able to be restarted after 30 minutes. The check engine warning light was illuminated. The vehicle was taken to a dealer where it was diagnosed, and the transmission was replaced. The manufacturer was notified of the failure. The failure mileage was approximately 42,000.
While driving, the rear right suspension trailing arm got sheared/broken apart into 2 pieces at about 1 inch away from the bushing and the welded spot. The car lost control while breaking.
Blue smoke and hesitation as if motor will turn off. Blue smoke upon turning suv on.
Front wheel bearing issue. Very luckily made it to trusted local shop. Mechanic said we are lucky wheel did not fall off. We wanted to drive to Subaru, he said we would not make the trip. No warning lights. Did not yet have inspected by Subaru, will do next service.
Sunroof glass broke. No apparent reason.
Car has been not able to roll up driver side window for a year randomly. Suddenly 3 years old and battery is draining and RAB and Eyesight and engine light on. Took in and saying can’t replicate window after they DID replicate it 3 months ago and did not solve issue. Did battery parasitic draw and numerous parts of car are draining battery. Cannot find source.
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 while driving approximately 15 MPH, the vehicle lost motive power and stalled. No warning lights were illuminated. The vehicle failed to restart and was towed to the residence. The vehicle was then towed to a local dealer to be serviced under NHTSA Campaign Number: 22V907000 (Electrical System). The contact was made aware that the VIN was also included in NHTSA Campaign Number: 21V955000 (Power Train); however, the mechanic was unable to complete the recall repair because the vehicle had a Salvage Title. The vehicle remained at the dealer awaiting the repair. The manufacturer was made aware of the failure. The approximate failure mileage was 20,000.
Car system drains battery for no reason. Opening a trunk or door for a 5-10min to load or unload vehicle is enough to drain a new full battery. This can leave people stranded in parks and remote areas. We have had the battery checked and verified it is good. This problem has happened multiple times on our Ascent.
Rear lift gate drains battery to the point where the vehicle won't start. The tailgate will beep three times, but will not open. Within 24 hours, the battery is insufficient to start it. You have to do a manual override to open the lift gate. The battery, starter and alternator were all tested and had no issues. I have to keep a jump pack in the car as the issue has become more frequent. The local Subaru dealership in Mequon, WI said they would replace the battery, but won't replace the module identified in a technical service bulletin for no charge: https://static.nhtsa.gov/odi/tsbs/2019/MC-10163522-0001.pdf This seems to be a very common problem with the MY19 Ascents.
