2012 Subaru Legacy transmission problems

Filed Dec 23, 2025 · Engine, Transmission · WA

My 2012 Subaru Legacy experiences involuntary engine stalling when coming to a quick stop, such as in stop-and-go traffic or during sudden braking at intersections. When the engine shuts off without warning, power steering and braking assist are lost, creating a serious risk of collision. This is a known issue documented by Subaru of America in Technical Service Bulletin 16-90-13R, applicable to 2010–2012 Legacy and Outback vehicles with CVT transmissions. Subaru attributes the condition to excessive thrust washer wear inside the torque converter, which prevents proper release of lock-up clutch pressure. Subaru describes the condition as similar to stopping a manual transmission vehicle without depressing the clutch, which inherently results in engine stalling. Subaru later redesigned the torque converter as a countermeasure beginning in October 2013, indicating prior knowledge of a defect. However, Subaru never issued a recall or notified owners and addressed the issue only through a non-customer-facing service bulletin. I contacted Subaru Customer Advocacy to report this safety concern and request assistance with the repair (quoted over $4,000). Subaru acknowledged my concern but declined responsibility, citing the vehicle being out of warranty and stating that TSBs are not customer facing. Subaru did not confirm whether the vehicle is safe to drive with this condition. This issue represents a safety defect, not a warranty dispute. Vehicles that can stall unexpectedly during normal braking events pose a serious safety risk, and many affected vehicles remain on the road today.

CVT transmission issues persist beyond the limited warranty extension that has now expired from Subaru. Vehicle RPMs regularly drop from 1000 to 500 when coming to a stop, causing engine to knock as it tries to stall. Vehicle then occasionally hesitates when attempting to move under power. Knocking and near stalling occasionally results in a sensation of vehicle being hit from behind while stopped with vehicle in drive and brakes applied.

Faulty torque converter. The car will unexpectedly turn off when coming to a fast, sudden stop. The 1st time it happened, I was in a left-hand turn lane and didn't realize my car had turned off and I had to quickly restart it to complete the turn. A transmission repair shop confirmed that the torque converter and valve body would need to be replaced. No warning lights, messages or other symptoms appeared before the incident. There is a safety bulletin from Subaru on this issue but because my car has a salvage title, it would need to escalate to a recall in order for Subaru to complete the repair free of charge

The vehicle will on occasion stall when coming to a complete stop. It is a known issue that has a service bulletin. Has something to do with the internals of the torque converter failing. Depending on where the vehicle stalls this could create a serious safety concern. Happens more when the vehicle is cold.

Please see ODI#11486236 & request # 562681 “ part 1” I wrote complaining about a 2012 Subaru Legacy Torque Converter issue. It was “ out of warranty 7/31/22 or 100k miles. At the time it started stalling it was at 103k miles in August 2022! I did not feel comfortable driving it. On 10/19/22 My mechanic drove my car & it shuddered & stalled at intersections for him also. I did not feel comfortable driving it 25 miles to a Subaru dealer to have them check it, diagnose it & repair it. My mechanic replaced the Torque Converter as well as the appropriate fluids. It cost about $1500 for parts & labor. Since this is a FAULTY part installed prior to purchase I feel Subaru needs to recall all these vehicles affected. I emailed you MULTIPLE emails online re: multiple complaints about this faulty part which causes a dangerous situation stalling at lights & intersections requiring one to stop & start. I was almost broadsided a few times. Subaru should do the right thing and recall all vehicles involved & your Agency should do the right thing & demand it for the safety of the public.

In August & September 2022 , 4 times I was stopping at stop signs & red lights and my car shuttered & stalled. No warning lights showed on the dashboard. I contacted my mechanic & he said he was aware of this issue on certain Subarus, possibly a Torque Converter defect but thought there was an extended warranty & I should look into it. My car was purchased 7/30/12 & had 103,000 miles on it when this issue started in August. I wrote to Subaru of America explaining the problem. They told me that my car was out of the “warranty” since it expired at 100,000 miles OR on 7/31/22. They said I’d need to take my car to a Dealer & have them diagnose the car, & if it was this issue then it would be reviewed to see if they would offer any “good will assistance”. After reading many blogs I’m noticing many Subaru owners complaining of similar dangerous stalls. Why hasn’t Subaru been forced to recall all these vehicles? This is a dangerous situation. I also read an article in FORBES MAGAZINE From 2017 by Chris Jensen that Subaru was allowed to offer extended warranty on this faulty transmission part instead of a recall being issued. I. Don’t understand how you can overlook this SAFETY issue. I would like to know what recourse I have since this started happening just outside my warranty limits. Subarus comment re: “ it would be reviewed to possibly offer some good will assistance” Is just not good enough. I would appreciate a response and some assistance in this dangerous situation. I have a date set in October to have my mechanic check it Thank you.

The contact owns a 2012 Subaru Legacy. The contact stated while driving 35 MPH and coming to a stop, the vehicle shuddered and shut off. There was no warning light illuminated. The contact was able to restart the vehicle and continued driving. The contact’s husband, an independent mechanic, replaced the spark plugs, ignition coils, and fuel filter; however, the failure reoccurred several times while driving. Upon investigation, the contact became aware of Subaru Technical Service Bulletin Number: 16-90-13R for transmission failure. An unknown dealer and the manufacturer were notified of the failure and informed the contact that the vehicle was not eligible for the Technical Service Bulletin repair due to the mileage. The vehicle was not diagnosed or repaired. The failure mileage was approximately 145,000.

First time car stalled when brakes were applied. Car (subaru legacy 2012) had 140k miles on it. Went to a subaru dealer and they replaced the torque converter. There is a service bulletin out there for this model which caps the mileage for free repair at 100k miles. After 30 miles with a new torque converter, car started shuddering at 45mph. Multiple sensor lights came on with steering becoming difficult. Turned into a small street where the car stalled at low speeds. Took a couple of tries to start the car and sent it back to the dealership for repairs.

Got my subaru at a certified dealer and they did all the airbag recalls good 😁 and thank you but I been driving it to and from work no big deal 35 mile round trip but noticed it was hard starting like no fuel or spark so when it was due for inspection I told them to change the plugs at 59k miles they did and drove it for a month or two and notice a winding noise and shimmy and when stoped at a red light it almost stalled out light when very dim and came back on and I've notice over a week it's been loosing power like the tahoe I had that the torque converter was going so I called the nearest dealer and asked about the transmission and they looked at it and said it passed all of subaru testing and just drive it and asked what about the shimmy when driving and shifting gears they said engine lope and just drive it till it shows a light or fails it's under warranty till 100k miles but I don't want to drive it if I'm in traffic and it stalls and cause a reck or engine blows up due to engine lope and asked about the engine lope what is causing it they can't tell me it now has 61k miles on it and a yard ornament because I don't want to cause an accident on the road
