Transmission & Drivetrain complaints by model year
Good Day! I bought my 2021 Subaru Outback XT Onyx in Jan 2021. I had waiting 6 yrs for Subaru to use the Turbo Motor in the Outback again. I've had this car for 5 years with my warranty running out Jan 2026, but I only drive 5000-7000 miles per/yr. Current odometer is 29,901 miles. At my most recent oil change service at the Dealer, they showed me a video of my cars drivetrain from underneath. There were two bad seal leaks. One at the transmission pump housing and the other at the Upper Oil Pan. I had been there for an oil change a year earlier for the same service and there was no mention of these issues! After speaking with the service advisor, he said to call Subaru Customer Advocates. They listened to my situation and a few days later offered a $1400 credit for a $4000 job that involves the removal of my cars engine (upper oil pan) to replace it because it's bolted to the frame there. The other leak seal involves dropping the transmission. These are major repairs that following will dampen my ownership experience after decades of Subaru praise by Americans. I researched this issue online and found out there was a manufacturing defective regarding the silicone liquid seals they used for 2020-2022 Outback, Ascent, & WRX! This procedure was used throughout the driveline with the Turbo Motor & CTV Trans. There are 1000s of accounts of this defect placing burden on the owners of these cars who bought them in good faith. I did the research, called the dealer & Subaru with the discovery & overall complaint! I asked for 80% to 100% help with these repairs because how many more will I have to deal with after these two are repaired??? I have received zero responses from either after expressing that this was a known defect, Bullitens went to all the dealers, nothing was mentioned to the owners, and they've just covered those cars still under warranty. Since I didn't drive enough, the seal issues on my car took longer to start leaking, and then out of warranty. HELP!
NHTSA complaint #11758285 — an unverified report by a vehicle owner.
Driving at speeds around 40 and when braking to turn, the brakes jerk and feel like they are not engaging properly. It has happened to a different driver, twice both times on a 90 degree day, a few minutes after the vehicle had been started and the air conditioner was running on high. After this happened we Googled the issue to see what the problem could be. The Google search shows a Subaru Service Bulletin #16-150-24R, 09/13/24, revised 12/03/24, showing our year and model of vehicle and a VIN # for all those models as TBD. The service bulletin list the exact problem that we had, and listed the AC running. The service bulletin list a fix of replacing the Transmission Control Module. This would be covered under 5 year 60K miles warranty for the Powertrain. Local Subaru dealer doesn't want to fix it because they can't replicate it by driving it. Subaru Customer Advocacy doesn't want to do anything because my VIN is not listed and they say the TSB are not for the customers to see. They refuse to let me talk with anyone further who would determine which VINs are going to be covered in this TSB.

I was in an automatic car wash, approaching the end of the tunnel. The car was running but in neutral. I put my foot on the brake pedal and shifted into drive. As I moved the shifter, I heard a scraping sound followed by a clink sound, then the car surged forward and accelerated toward a stone wall directly ahead. I turned hard right as I hit and held the brakes. I missed the wall but hit a pickup truck that was coming up the drive. My car hit the left front fender of the truck with my left front fender. The truck, which appears to have been "lifted" rode over the top of my fender and both vehicles scraped down the left side of each other. I finally got the car stopped some distance beyond the truck. Both vehicles had to be towed away from the scene. My car is currently in the Caliber repair shop with nearly $23,000 damage. The Knox County Sheriff's office responded but they did not file a report as the incident took place on private property. Even so, the Deputy did interview both drivers and several witnesses in front of his body camera. I understand those videos are maintained at the Sheriff's office.

From when we purchased this car new until the day we traded it. There were many times on the freeway at 60-65 MPH that you would need to move over a couple of lanes and went to wide open throttle and the car would simply do nothing for 1 to 2 seconds. I recently learned that in 22' Subaru had a software update to rectify this issue. Meaning there are plenty of Subaru owners who are driving around in cars that put their safety at risk. When you step on the gas you need and expect the car to accelerate .

When traveling eat 6-65 mph and needing to merge and stepping on the gas pedal all the way the car would just sit there and do nothing for 1-2 seconds. this was not a one off situation. The car would do this regularly until I found out subaru had a fix for the transmission software. I recently had to pay to have this done even though my car was still within the powertrain warranty because Subaru said it is maintenance .

Please contact Carvana and make them take that vehicle off the market. I purchased it and by chance found out that bottom parts like subframe and exhaust pipe were inadequately installed . The mechanic said eventually I was going to flip over myself on the highway in that car. He also stated that this repair cost would be around $8000 - more than half of this used car was offered for on Carvana. I returned the car. Half a month later is back on Carvana website for the same price. Please help! I have no alt motive but try and save someone’s life.
NHTSA complaint #11750991 — an unverified report by a vehicle owner.
The CVT failed at 62 miles per hour on a busy interstate, XXX. This caused the drivetrain to lock. The car has been repaired and traded locally in [XXX]. The car was very difficult to steer with locked wheels in traffic. This was a rapid evasive manuver on a busy interstate. An undrivable vehicle on an interstate is life threatening to many. Flat bed driver told me I was lucky to steer off of lanes onto shoulder with four locked wheels. This incident put me in mild shock. The Subaru dealer had to replace the transmission. The dealer and Subaru Regional Rep. examined the CVT failure. It was outside of the 100,000-mile warranty by about 895 miles. Repair invoice attached. I did not have advanced warning of CVT failure. There were no warning lights on before the CVT failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2022 Subaru Outback. The contact stated that while driving at an undisclosed speed and coming to a stop, the vehicle then failed to accelerate or drive forward. While depressing the accelerator pedal, the engine revved excessively to approximately 7,000 RPM, but the vehicle failed to respond. The failure reoccurred consistently after coming to a complete stop. The vehicle was taken to an independent mechanic and was diagnosed with transmission failure. The dealer was notified of the failure on several occasions but was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 157,777.
NHTSA complaint #11746719 — an unverified report by a vehicle owner.
While driving the 2016 Subaru Outback, the vehicle experienced a sudden, catastrophic failure of the Continuously Variable Transmission (CVT). The transmission completely failed, resulting in an immediate and dangerous loss of propulsion while operating the vehicle. This created an immediate safety hazard for myself, my toddler and other drivers on the road, as the vehicle could no longer maintain speed or accelerate safely to clear traffic. A certified repair facility diagnosed the issue as a complete internal mechanical failure of the transmission, requiring a total replacement at an estimated cost of roughly $11,000. This generation of Subaru CVTs has a well-documented history of premature, catastrophic mechanical failure, which Subaru of America has previously acknowledged via past warranty extensions. The sudden loss of power caused by this engineering defect poses a severe and ongoing safety risk to consumers.

Recently, the 2022 Outback my mom drives has been having some strange electrical issues. About a year-or-so ago the battery in her outback died. Not unusual in Arizona. I replaced it with an upgraded AGM (Interstate) version—same group, same cranking power. No issues. Recently, after an oil change at the dealer, she called back to report that a “Check Engine” light had come on. She was told that she probably had not put the gas cap on properly. Gas cap was on properly; light went off the next day. A few days later the Auto Stop/Start (ASS) feature started acting up (not functioning). A few days later the ASS turned the engine off and did not restart automatically—in the middle of heavy traffic during rush hour. The ASS light came on. The engine started manually, and we got it home. Battery was dead the next morning. I charged it up and took the car to the local mechanic for a quick assessment. The battery was fine, charging, but the car threw a Code: P0871 Transmission Fluid Pressure Sensor Switch. This mechanic told us that there was a Technical Service bulletin through Subaru that addressed this issue but was also aware that it could be caused by the ASS killing the battery OR other electronic modules which fail to enter sleep mode—which would also cause random lights to come on. An appointment was made to take the car into Peoria Subaru, thinking it would be something they could diagnose easily. It had previously been in for the routine oil change with the inspection. When we dropped the car off, I provided the Advisor the code and a associated TSB for the code. We got the car back that day and were told the following: The tech found that the car currently has a “Aftermarket” AGM battery. Subarus require a “Enhanced Flooded Battery” which would explain multiple codes found for loss of communications and parasitic battery drain--for systems that don't go to "sleep" when the car is not running.

I have a meticulously maintained 2022 Subaru Outback LTD that has now had 3 out of 4 OEM installed wheel bearings replaced due to failure with less and/or near to 40,000 miles on the vehicle. The power train has a warranty until 2027, however, I felt that this is a recall worthy event and asked Subaru of America to either extend the powertrain warranty or replace the one remaining, original bearing. Case # 260430-1901212 They will not replace it after many email exchanges and escalations. Having had a older car with a bearing seizing and tearing off from the vehicle into oncoming traffic, I feel this warrants notification.

On deceleration the cars CVT has an intermittent shudder. Sometimes minor sometime severe making it feel like the wheels will slow too quickly and lose contact with the road. The dealer verified the problem changed the transmission control module and re programmed it. That did not correct the problem. I can’t force it to recreate the problem it happens when one least expects it.i take the car on only long trips to visit family in NY 600 miles away and during the trip it happens multiple times times. Brought it back to the dealer and although they previously confirmed the problem it did not do it for them this time and corporate would not allow further diagnosis other than a test drive and scan for codes. The problem doesn’t cause a code to be created. In my opinion as a person who worked on cars for 55 years, the next logical step would be to drop the CVT pan and inspect the fluid for metallic particles or contamination. When doing a deep dive into potential causes of the problem 1 make sure the programming is up to date , confirmed. Second the torque converter is not fully disengaging. This causes tires to nearly lock up and a potential loss of control. The dealer can only do what corporate allows. Corporate is willing to pay to have them drive the car around, at my liability if they have an accident . But not pay for 5 quarts of CVT fluid and the time to drop the pan and inspect it potentially putting my life and my passengers lives in danger.

My transmission has started to fail. The check engine light came on the error code read p0867, transmission fluid pressure. Other lights came on as well because it tripped the rest of the sensors because of the CVT failure. This seems to be a common problem in Subarus

NHTSA complaint #11736441 — an unverified report by a vehicle owner.
I was reversing out of a residential driveway onto a county highway when the I had a complete loss of movement. Shortly after the total loss of power, the CEL illuminated. If I had been on the highway, the driveway is near a blind curve, I would've been sitting in the road with no way to move putting me in a dangerous situation. The transmission failed at right at the end of the driveway so I was able to put it in neutral and move the vehicle by hand. There were no symptoms or warning lights prior to the failure. I had it towed to the nearest dealership where they diagnosed a complete transmission failure and recommend a complete transmission replacement.

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.
NHTSA complaint #11727143 — an unverified report by a vehicle owner.
The contact owns a 2024 Subaru Outback. The contact stated that while driving and coming to a stop, the vehicle shuddered and jerked unexpectedly. There was no warning light illuminated. The vehicle was taken to the dealer and was test-driven, and the failure was duplicated. The dealer replaced the transmission control module and reprogrammed the transmission; however, the failure persisted. The vehicle was taken back to the dealer, where it was test-driven, but the failure could not be duplicated, and no diagnostic trouble codes were found. The contact requested a more thorough diagnostic test of the vehicle; however, the dealer declined. The manufacturer was contacted, and a case was filed. The contact stated that the manufacturer had not approved the request for a thorough diagnostic test due to the cost. The failure mileage was approximately 1,000.

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.
