Power Train Problems of Subaru Outback - part 1

The failure involves the engine (powertrain), which was under warranty. The vehicle has experienced four catastrophic engine failures resulting in sudden loss of power, including at highway speeds (65–75 mph). The most recent failure also involved an oil-saturated catalytic converter. These failures occurred between 06/25/2024 and 03/16/2026. During this ~629-day period, the vehicle was only in my possession for about 184 days, as it remained at the dealership for diagnosis, repairs, and repeated engine replacements. The issue remains unresolved. The vehicle is currently in my possession, available for inspection, and is not being driven due to safety concerns. All failures occurred during normal driving and caused sudden loss of power with no prior warning, leaving the vehicle inoperable and stranded. This created a significant safety risk due to inability to maintain speed or safely merge, increasing the likelihood of rear-end collisions. The failures have been confirmed by an authorized Subaru dealership, with multiple engine replacements performed under warranty and most recently as a goodwill repair. Both the dealership and Subaru of America have acknowledged they cannot determine the root cause. The dealership’s operations director stated the vehicle is not safe and he would not allow his family to drive it. The vehicle has been inspected multiple times by the dealership and Subaru of America. However, no inspection reports, diagnostic data, or detailed findings have been provided despite repeated requests. Additional issues (including a broken axle and oil-saturated catalytic converter) were only identified during a third inspection after being missed previously. Requests for explanation were not answered, and further details were withheld as “internal. ” there were no warning indicators prior to the first three failures. During the fourth, a temperature warning appeared only seconds before failure.

My 2016 Subaru Outback cvt transmission has exhibited an intermittent jerking and grabbing sensation when accelerating from a stop, worse when cold, since at least February 2023. This is a known defect covered under Subaru warranty extension bulletin 16-115-18. February 2023 — an authorized Subaru dealer documented the complaint in writing. The technician stated the vehicle never warmed up during the test drive and dismissed the concern. The cvt issue was never repaired. I was never informed of Subaru's cvt warranty extension program. February 17 2026 — seven days before my warranty expiration — the same authorized Subaru dealer physically identified and documented a cvt oil pump cover leak. The same jerking complaint was again documented in writing. No repairs were made and the warranty expired one week later. The cvt defect has been physically confirmed by an authorized Subaru dealer within the warranty period and Subaru of America has denied my warranty claim in writing. This issue presents a safety concern. The unpredictable jerking and hesitation when accelerating from a stop creates dangerous situations in traffic, particularly at intersections and when merging. The vehicle is available for inspection upon request. Subaru chose to handle this known widespread defect as a quiet warranty extension rather than a mandatory recall despite hundreds of owners reporting identical symptoms.

2025 Subaru Outback onyx edition purchased 3/2025. Approximate mileage at time of incident 7000. On 2/10/25 around 6am car is remotely started with Subaru app from iphone on flat gravel surface. Car was in park. Go out car not there moved almost a car length down a hill left turn then over an embankment into a ditch where it finally rested still running in park when found it. Why or how is this possible when done this before no issues. Took to dealership checked visible damage snapped bumper back in get hood and grill shutters checked by body shop. Stating no malfunction and said safe to drive until we did that. One week later the car is started and all sorts of lights appear on dash took back to dealer additional problems found in front end and underneath. Told us we could still continue to drive it with lower core support damaged. Why did lights come on week later no airbags deployed when hit ditch. No notification or contact on app when crash happened and how was the steering affected when vehicle was in park. So many questions no definite answers yet? definitely a major safety concern. Left with new vehicle damage at this mileage and we feel we are not at fault.

I'm writing to request assistance with my recall. This recall was first reported to the local dealership over one year ago. They have had me take the car back 4 times for inspection. Since that time as the problem has proceeded to get worse, which will now cost even more to repair, and increase the likelihood of the transmission damaging other parts of the drivetrain. Now I just received notification that they will not perform the recall as my vehicle doesn’t qualify. It has the problem of transmission slipping which is what the recall is for. I saw the pictures they took that looked exactly like the problem specified. I do not have $7000 dollars plus to fix the transmission. I can’t sell the car because the VIN will show the recall (which I’m sure they will try to just remove). All they have done is waste my time for the last year to do what? gather enough evidence to try and get out of the recall?.

This concerns my 2025 Subaru Outback touring xt- with a turbo charges engine and standardd cvt transmission. When I get to street speed and brake to slow down, as the car slows and the tach decreases to 1000 rpm +/- a bit, the car shows an obvious power surge that can be felt through the accelerator and brake pedal and can be clearly seen on the tach as a jump to about 1100 rpm + . I had the first oil change done at 2500 miles or so at the dealership and asked them to see what it was. The electronic system diagnostic monitor they plugged the car into showed no issues. But, the technician doing the work could feel the same thing. The dealership had just received a new car with same features as mine, so they got in it, and the same thing happened. I was simply told that was the way the care was. I really doubt it. I will be having another oil change soon, perhaps this Saturday, and will ask them to put it on the diagnostic monitor again and see, but this can be a little unnerving. This is a continual and ongoing issue. There is no one specific date as requested below. So, I am just showing 1-1-26 to fill the blank. Thank you [xxx] [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On December 28, 2025, my 2020 Subaru Outback lost the ability to engage any gear (drive, reverse, or otherwise) while maneuvering at low speed to make a u-turn. The vehicle became inoperable immediately and was towed to the dealer. The dealer confirmed via text and written estimate that there was no external damage, the failure was internal to the cvt transmission, and the transmission requires replacement. This vehicle has approximately 90,023 miles. The failure occurred under the mileage and age range covered by Subaru cvt warranty extensions for similar vehicles. Subaru of America reviewed the case and denied coverage, citing VIN exclusion and prior service gaps that predated my ownership. The vehicle is currently inoperable and presents a safety risk due to loss of propulsion. I am reporting this to NHTSA because it may indicate a systemic defect in cvt transmissions on this model year Outback.

- engine failure. Yes. - at a stop light the auto-restart function failed, following this event the vehicle began making a knocking noise, we towed it to the dealership for evaluation and their diagnosis was that it needed a new engine. - dealership stated they too heard the knocking noise in the vehicle and it is engine damage due to low oil. However, the dipstick read fine when we took it into the dealership and we did not have a low oil warning. - inspection completed by dealership - received no warning lights nor messages regarding symptoms of the problem prior to failure. Initial event happened on 12/26 when at a stop light following the auto-off during braking function the car did not restart automatically. Car was turned off, and restarted. Following that event the vehicle had a knocking noise that increased in volume with driving. Did not drive the car after arriving to our destination. Towed the car to the dealership where we were told it needed a new engine.

After a transmission replacement performed by bud clary Chevrolet, inc. In longview, wa on September 9, 2025, my vehicle was returned to me with critical components left unsecured. On November 19, 2025, an independent mechanic discovered loose suspension bolts connecting the ball joints to the spindles on both front wheels. On November 29, 2025, Subaru of portland documented additional unsecured and unattached components related to the prior transmission replacement, including loose mounting hardware and a disconnected pcv hose. Subaru of portland’s written inspection states that the loose bolts would have been unsafe if left uncorrected. These conditions were present after a major repair and created a potential safety hazard while the vehicle was being driven. This complaint concerns an unsafe condition caused by improper workmanship during a vehicle repair.

I was told by the dealer that my 2019 Outback had a cam carrier oil leak. At the time, my car had 50,700 miles on it. My drivetrain warrantee was for 5 years or 60,000 miles. I was over on the years but under on the miles. The repair was estimated to cost $4,500. 00. The dealer said that this oil leak is common and even when repaired it could leak again. This is a design flaw that Subaru has not addressed. There are many articles on it. This has been a problem because Subaru uses a boxter engine and this engine has historically always had problems with oil leaks that cannot be fixed. It was also disclosed that there was a chance that oil leaking onto the manifold or exhaust could cause a fire in the car which caused me alarm. My wife and I are seniors, and we cannot afford to get stuck in the car and perhaps with car on fire. The dealer could not do anything, so I called Subaru directly and spoke to their consumer advocate dept. (incidentally, I had two previous repairs to the electrical system and computer system fixed by Subaru at no cost even though we were past warrantee. Subaru decided to extend the warrantee on the two previous issues. ) after several calls Subaru told me that they would give me a $1,500 credit towards the $4,500. 00 for the repair, which I said was not nearly enough and did not solve the problems. I explained that we are apprehensive about the car because the leak could happen again and there is a chance of fire. Subaru told me that the chance of fire is low and at an acceptable level. Any chance of fire is not acceptable to us. I was going to sell the car outright, but the oil leak would cause a major devaluation of the car, so I had it fixed and repaired last week. My ongoing concern is that this oil leak is a recurring hazard that can cause a fire. I believe this problem should have been handled through a no cost recall. The dealer said this is a common problem, but I could not get any further info on the issue.

My cvt transmission started having problems with the valve body inside the transmission. On acceleration from a complete stop my vehicle would start "bucking" hard causing a violent back and forth rocking or "jerking" of the drive train and vehicle. I did not request a inspection of the failed valve body when I paid to have it replaced. The life and safety of myself and others are at severe risk of injury or death resulting from a complete failure of the valve body component when driving on highways or other roads because without any warning the vehicle will come to a complete stop which would cause a rear end collision possibly at highway speeds. Also I'm concerned about the torque converter having a failure because of the intense pressure from the failed valve body with the constant "bucking" on acceleration. I took my vehicle to both a independent transmission shop and a Subaru service center and the independent transmission shop told me I needed a new transmission and the Subaru service department kept telling me they didn't know what was causing my vehicle symptoms. Subaru of America extended the warranty on my vehicle to 100,000 miles because of the problems with their cvt transmissions but because I bought my vehicle used with over 100,000 miles on it they refused to either pay for 50% or 100% of the replacement cost. No warning lights came on but when the valve body completely fails then the warning lights will illuminate. My Subaru case number that was denied is (case# 250820-1801058) for Subaru extended warranty for cvt transmission.

The contact owns a 2020 Subaru Outback. The contact stated that while attempting to make a turn, the transmission was slipping while attempting to shift gears. 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 approximate failure mileage was 56,700. The VIN was not available.

When I parked my vehicle in the garage, I smelled an odor coming from the engine compartment. I found that the front right inner axle boot had leaked grease. I then saw that the grease covered the catalytic converter. I am not sure when this started to be a problem, but my main concern was it could have started a fire.

My name is [xxx] [xxx] phone number: [xxx] my complaint is with Subaru of America, 1 Subaru drive, camden, NJ 08103 phone number: 800-782-2783 I would like the pennsylvania state attorney general’s office to become involved with the two lemons/pieces of junk my wife and I have been sold. My Subaru is a 2019 Outback and my wife’s Subaru is a 2020 forester. My ongoing problems with my 2019 Subaru Outback are as follows and in my opinion, I am driving a very unsafe car putting our lives at risk: 3 batteries prior to 80,000 miles resulting from a class action lawsuit filed against Subaru. Replacement of the ecm or engine control module. Burns a quart of oil at the price of $11. 00 per quart every 3,000 miles, that’s an engine problem. Right front axle broke and had to be replaced. After replacement of the right front axle, the right front axle seal, which is the axle replaced started to leak and I was charged to replace the axle seal due to a mechanics incompetence. I received a card from Subaru stating a windshield issue. Received another card regarding a fuel pump issue. A letter received this past week from an apparent cvt or continuously variable transmission issue. Now my radio stations jump around arbitrarily changing stations, tracks on my cd, and my hatch doesn’t open, but gets stuck shortly upon opening. This car is a lemon, a piece of junk and very unsafe. How many more problems are unknown to us and when will any of them occur while we are driving putting our lives in danger. If Subaru had any ethics character integrity or business morality they would have replaced this piece of junk. They are a horrible company to work with information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I purchased this car may 28th 2025 and had it over the weekend and check engine light came on and took it Monday once shop opened and came back for catalytic converter and O2 sensor I letted the dealership know about it and said its not much that I can fix it but I figured would say that since was a as is car and just had to come up with money. . . Only thing month later it stalled on me and had to take to a shop to see what it is and came back for transmission but that shop told me the car never should have been sold I never try to let them know about that its been sitting since July when that happened I been trying to talk to consumer protection services but noone willed to help but since last year was so rough I just wanted to try again once year is up.

It is a known issue with Subarus of this year that the engine will stall at random intervals when stopping, weather at a stop sign or stop light, warm or cold, fast stops or regular stopping. There is no consistency to it, completely random. There are no warning lights that appear, I have not taken this car to the dealer because after purchasing it I cannot afford to take it to the dealer. I purchased this car used for my elderly parents and this is a disturbing problem that could get them hurt or killed. Why has this known issue not been recalled? there are multiple service bulletins reported to NHTSA addressing this issue but no recall?.

We had had no issues at all with our 2022 Subaru Outback until June 2025. Mileage at the time of the incident was approximately 52,000. We were driving one evening in June and all of a sudden the engine stopped and we could not drive it. It only produced a knocking sound when we attempted to turn the engine on. We had the car towed to the dealership and after taking the engine apart, they reported that an intake valve broke, flew and split one of the pistons causing the motor to seize up. There were no warning lamps, messages or other symptoms prior to the engine failure. Regular oil changes had been performed on the car. This issue came completely out of left field as we had previously had no engine issues.

Purchased used with just over 60k miles & have had less than a year. Vehicle still under 80k miles. Told transmission needs replaced but found service records from previous owner which shows fuel pump replaced twice at about 20k mile intervals & I am just under 20k miles past previous pump replacement. Vehicle does not run at the moment & warranty company refusing to help.

The contact owns a 2011 Subaru Outback. The contact stated while driving at various speeds, the vehicle failed to properly accelerate while depressing the accelerator pedal. The vehicle was taken to the local mechanic who diagnosed that the transmission output shift was bent and needed to be replaced. The vehicle was not yet repaired. The manufacturer and local dealer were not notified of the failure. The failure mileage was 100,000.

The car shifted (transmission) into neutral when cruising down the interstate at 62 mph and stayed in neutral until the ignition was turned off. With no brake light cars were not worn and was nearly hit from behind. 2 weeks earlier the same happened on a city street. There was a previous transmission recall wrk-21chain slippage recall on this vehicle that apparently didn't correct the problem.

Torque converter issue that causes stalling similar to a manual transmission vehicle. The issue should have been a full recall but instead was only a "bulletin. " for my own safety, I am stuck paying several thousand dollars for an issue the manufacturer is aware of but refused to cover by full recall. It is not just wear-and-tear, and is a danger to myself and other drivers on the road. And because the previous owner(s) were negligent in making sure the vehicle was repaired under warranty, I'm left paying a giant, unexpected bill. Does that seem like the right thing to you?.

Due to a known manufacturing defect in the automatic transmission acknowledged in TSB 16-74-09 the driveability of my vehicle has been severely hampered and the shuddering/vibration is steadily worsening. I wasn't aware of this torque converter defect or an available remedy until well after the warranty expired as I didn't have access to the TSB. This is apparently a widespread problem affecting many vehicles of the era based on online forums and other complaints to NHTSA. I took the vehicle to dealerships over the years for related transmission issues but they "couldn't replicate" my concern. Recently, a local dealership has confirmed our transmission is affected but it does not throw any trouble codes or illuminate warning lamp as these underlying mechanical defects are not monitored by the obd system. Having a gradually failing, defective transmission is a safety issue as we can grow complacent and it could give out any time without warning while driving. The vehicle is certainly available for inspection. It has been impeccably maintained, and none of these issues are due to mechanical wear and tear or neglect. It's unbelievable that a known manufacturing defect in the transmission would not affect every vehicle with that unit and be subject of a broad recall.

My car had an unintended acceleration that caused me to go in a ditch and hit a tree. I could not get car to stop when I realized it was increasing speed. It all happened very fast. My car was totaled. All airbags deployed. Front right side of car was completely destroyed. There were no warnings. My insurance company has the car on their tow lot. I have sprains and bruises on my right side and a slight concussion. So thankful that I was not in a parking lot or in heavy traffic or near any walkers.

Vehicle had 45,000 miles on it when right rear wheel bearing failed. It was covered under 5 year/60,000 mile warranty and was repaired today by a certified Subaru dealer and I no longer have the bad part for inspection. Safety risks would be anything that occurs from a bad wheel bearing like wobble, seizing, overheating, and more damage to other drivetrain components. You could hear the wheel bearing noise at 20 mph constant while driving, only getting louder with increased speed. No warning lights were present on the dash. I feel like at 45,000 miles, a wheel bearing should not be failing.

I noticed a metal sound when I accelerated then the car jerked forward a few times. Shortly afterwards, ~5 min, the dashboard lights came on:automatic transmission oil temperature, blind-spot detection, check engine, eyesight system, reverse auto braking and vehicle dynamic control. I was able to drive slowly back home but not sure what is going on with this 3 year old car with 47,000 miles on it.

Had my recalls completed and started having jerking on my way home from the dealership. Didn’t have any issues prior and I drove 2 hours to the closest Subaru dealership. Had transmission serviced and still doing it. Read the fuel update and head unit updated could take a bit longer to learn and could cause jerking but still happening 3 weeks later. Transmission was serviced last week. The shop to do it stated didn’t notice metal shavings nor sounds in the transmission or the oil and suggested it be the computer problem with the recall fixes.

A transmission that was replaced in July of 2023 went bad un December of 2024 and dealership won't give reasons why transmission went bad or what caused a almost brand new transmission with less than 50,000 miles on it went bad. They are demanding we pay $5000. 00 dollars on a transmission that was replaced under the extended warranty on cvt transmission from Subaru. Which also extends to the brand new transmission. They are demanding their loaner car back and refusing to honor extended warranty on new transmission which the gave us which is bad. They will not give us anything other than it is bad. No information what so ever is being given to my husband or I as to why, how or what happened. My car will not move unless it is pushed by someone. They are refusing to honor their recall warranty or provide a loaner while dealing with their corporate offices on this issue. This is after in the past 1 and a half years my car has been in their shop for well over 8 months and I am still making payments on this vehicle. They will not even provide paperwork on the issues with my vehicle.

When coming to a stop the rpm's drop and the engine will stall, similar to not engaging the clutch on a manual transmission. Luckily there has not been a crash to date but the condition has worsened to the point it is no longer safe to drive and must be repaired. This is a known safety flaw with the torque converter and Subaru denied any responsibility or assistance in the quoted $2,400 repair.

Vehicle stalls when stopping. This is a huge safety issue because stalling at intersections can cause accidents. Dealership diagnosed a faulty torque converter. This torque converter (it should be part number 31100ab170) issue is widely known in this production series of the Subaru Outback. After hundreds of complaints were filed with the NHTSA, Subaru extended the warranty on all their automatic transmissions to avoid a recall around 2017, but closed the extended warranty in 2022. Subaru now tries to convince their customers that these vehicles are too old for the issue to be attributable to them, despite knowing that they equipped these vehicles with defective parts. See the following: [xxx] [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

When coming to a stop, the car shudders and often stalls just like if you didn't press in the clutch on a manual transmission. No warning lights or messages. See details in TSB- 16-90-13r. Subaru knows about this issue and it has been reported in many vehicles. My car was at a Subaru dealership at least half a dozen times during 2017-2018 when this issue came to light and no one notified us to have it checked. Fast forward to now and for the last year my car has been shuddering when coming to a stop, and about 2-3 months ago, it started stalling. This is an absolute safety issue and should be a recall. I've been in many situations where it stalls and I am vulnerable to getting rear-ended because it takes time to restart the car and get moving again. This is particularly true in traffic or situations where you need to stop suddenly and others behind you are not anticipating you being stopped in the roadway.

When coming to a stop at a stop sign, the car jerks and the engine appears to stall. I have brought it to 2 dealerships and both have said that it is "normal". I have had dozens of cars and none have ever performed in this manner. The adaptive cruise control and automatic emergency braking frequently brakes for no reason or does not recognize cars in front of me. It regularly misses large objects directly in front of the car. The system also has a lot of failures and turns itself off randomly for unknown reasons. (again, "working as designed").

While driving on the highway, we were forced to brake swiftly. As a result, the known issue of the torque converter in this model of car caused the engine to stall in the middle lane of the highway and almost causing our deaths as multiple tractor-trailers had to swerve to avoid our immobilized vehicle until it could be restarted. This could've led to to the deaths of me, my family and many other road-users. I can't believe this isn't a recall when it's such a wide-spread and known problem with this model.

I’m unable to remove the car key from the ignition when the vehicle shifter is in park.
