Owner reports
Selected complaints filed with NHTSA by 2012 Subaru Outback owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2012 Subaru Outback. The contact stated while driving 65 MPH, the vehicle lost motive power and decelerated, prompting the contact to quickly exit the roadway, where the failure persisted. Several unknown warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the continuously variable transmission (CVT). The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 125,000.
I own a 2012 Outback 2.5 Limited, which I purchased new from a Subaru dealer in Evanston IL in June 2012. It currently has about 76000 miles on it. In the last 6 months my car started to shudder when coming to a stop at a traffic signal, or sometimes while being stopped at the signal. The shudder is significant but typically momentary and happens randomly. From the last 2-3 weeks, the car has started to stall and the engine shuts down abruptly when coming to a stop. This is very stressful, but fortunately, so far I have been able to put the car in P and start it again every time. However, this is very dangerous and puts me and my family at grave risk of a serious accident from cars coming from behind as my car stalls abruptly. Again, this happens randomly which makes it even more dangerous and impossible to mitigate as a driver. …
Vehicle has always stuttered coming to stops but has began to start stalling. The problem was never diagnosed previously. Now that it is have found to be the torque converter I actually know what is happening. I don't think being unable to rely on you vehicle to continue running in an emergency stop or break pump is a safety issue Subaru should take lightly. I have been faced with two Subaru known problem repairs recently that I didn't know of at the time of purchase. The head gasket which left me stranded on a trip and a torque converter. The first was close to a 4k$ repair and the second is coming close to 2k$ repair. I am growing frustrated with Subaru ignoring how dangerous this and also how they are ignoring customer concerns. Both these issues are well documented by owners experiencing the same things I am. …
I own a 2012 Subaru Outback 2.5i Premium. The vehicle has approximately 161k miles. Recently, I have noticed the car beginning to stutter when approaching an abrupt stop. There have since been several instances where the car will stall when coming to a quick stop. This happened to me in the middle of traffic one day and I had my family in the car with me. In my opinion, this issue jeopardized the safety of my family. Stalling in the middle of the road and having to restart the car each time is a huge concern for me. My wife and I are now terrified to drive the car due to the looming safety concern. Upon further research, the problem stems from a faulty torque converter on the car, confirmed by TSB 16-90-13R. Subaru has not made this a recall unfortunately, but I don't feel I should be the one to pay the cost for a repair that is in my opinion very serious. …
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. …
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.

Concerns of The torque converter - there is very low engine RPM when coming to a stop. Thrust washer wear inside the torque converter causing restriction of the oil passage used to bleed off lock-up clutch application pressure. This has resulted in low engine ROM and stalling of my vehicle on dangerous intersections. My car stalled in an intersection several times due to this issue almost causing sever injuries or death. The problem has been reproduced and confirmed by an independent service center. Yes, has been inspected by independent service center. No warning lamps or other symptoms prior to the failure. They first appeared at/around 125,000 miles.
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.
The torque converter is failing at 113,00. It has happened at red lights, but more recently while on a Texas freeway that I had to come to a hard stop which cause the engine to stall out at 40 mph. My child was in the car and on a fast paced highway my safety was placed in jeopardy. It is going to the shop to be repaired because is this. I will have proof of repair service and faulty part. .
Torque Converter issue consistent with Subaru Service Bulletin 16-90-13. Although Subaru issued a service bulletin with extended warranty rather than a recall, I want to document this as an ongoing problem with the model year and still a dangerous one. 08/09/2021 the vehicle shuddered while coming to a stop at a light, like the RPMs were dropping too low. At the next light, the vehicle shuddered and stalled while coming to a stop at the light. I was able to restart the vehicle after I realized the engine was dead and I needed to put the vehicle back into park before it would turnover. I couldn't immediately identify what I needed to do to restart, since the car won't turnover in drive, so I was stalled for a cycle of the stoplight. A few days later, the vehicle again shuddered and stalled while coming to a stop at a light. I had been driving for maybe 3 minutes from a cold start. …
