2019 Subaru Ascent Powertrain & Transmission Problems

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.

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.

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.

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.

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.

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.

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.

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.

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.

2019 SUBARU ASCENT. CONSUMER WRITES IN REGARD TO TO NHTSA SAFETY RECALL 21V-955. THE CONSUMER RECEIVED A RECALL NOTICE AND WAS INFORMED BY THE DEALER TO WAIT FOR THE 2ND RECALL NOTICE. WHILE DRIVING 50MPH ON HIGHWAY, THE CAR JOLTED FORWARD, CONSUMER HIT HER HEAD AND WAS KNOCKED UNCONCIOUS.

As I am going up a hill I will be pushing on the gas and the engine will rev up loudly and the rpm will increase but the vehicle speed won’t increase or it decreases as I’m trying to accelerate. This is dangerous because the people behind me are expecting me to be speeding up to go up the hill but my vehicle will be slowing down and won’t let me increase speed. It has been to the dealer multiple times and they say they can’t find nothing wrong. We drove the mechanic around and it did the exact same thing I explained and he still said they couldn’t find anything wrong with it. I know this isn’t normal because when we first bought it, it did not drive like this. I’ve also had multiple people tell me they are experiencing the same exact issues. This has been going on for about a year now. It also has been doing a few other things as well.

On speeds of about 70+, both on cruise control and off, car jerks for about 5-10 seconds when accelerating on steep hills. It also happens after the car has been driving for more than 1hr or so. Fuel consumption is about 19-20mpg regardless of highway only driving contrary to advertised
