What owners say about the power train
Verbatim from NHTSA complaints, newest first
“While driving on I-5 at about 70 mph, I made a normal upshift from 5th to 6th gear in my 6-speed manual transmission. The shift lever went past the reverse lockout without my lifting the reverse pull collar (the owner's manual says the collar must be raised to select reverse) and the transmission briefly went into reverse at highway speed. The lever was in reverse for only a fraction of a second, but that was enough to strip the reverse gear teeth. There was no warning beforehand. I kept driving without knowing anything was wrong and found out later, when I tried to back up, that the vehicle has no reverse. The reverse lockout should make it impossible to select reverse during a forward upshift. Here it failed. Engaging reverse at 70 mph can damage or lock up the drivetrain and cause a loss of control or a crash in traffic. With reverse gone, I also can't leave the car in reverse when parking on a slope, as the owner's manual advises. Subaru appears to know about this. Service Bulletin 03-71-13 (07/2013) released a revised 6MT shift lever (P/N 35011CA010) "designed to improve the operation of the reverse selection mechanism," built into production starting in…”
“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.”
“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]”
“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 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.”
“The car stalls out at stops. It shutters and them stalls like a 5 speed car. I have almost been rear-ended on a couple occasions. It is now in the shop for a torque converter replacement”
