1 Power Train problem

Failure Date: 10/22/2025

An issue has surfaced with my car that it turns off while driving. Obviously this is a serious safety hazard and likely to result in an accident. Now that it has happened, it is continuing and frequently happening. I reached out to Subaru as I saw there was a recall for my car's make and model that is causing the same issue. The issue is listed as NHTSA campaign 19v297000, described as "the engine turning off unexpectedly can increase the risk of a crash. " and affecting many Subarus, including the 2011 Legacy. I believe my car is impacted given the behavior it is exhibiting. When I reached out to Subaru, they dismissed it saying it did not apply to my car and they were not willing to investigate. I believe this poses a grave risk to many people given that it will cause an accident and the severity of the defect.

2 Power Train problem

Failure Date: 10/10/2025

The week after purchase: the car shuts off when braking and needs to be put into park to be started again. Also the check engine light came on and I wonder if it has electrical issues.

3 Power Train problem

Failure Date: 07/22/2022

Sometimes as I'm coming to a stop, such as at a red light or a stop sign, just before I stop, the car lurches and then stalls. This is an automatic transmission car, but the best way I can think of to describe what is happening is it is acting as if it is a manual transmission, and when you come to a stop and don't press in the clutch. If this happens at an inopportune time, it could cause an accident. Possibly you're slowing down as you turn through an intersection and it lurches and stalls. You would then be stopped in the middle of the intersection. There are no warning lamps or messages before this happens.

4 Power Train problem

Failure Date: 02/03/2022

It's a 6mt. Randomly reverse stopped working. Seems like it wants to go in reverse. But when any bit of gas pedal pressed it grinds and pops out of reverse. I have no reverse. 1st thru 6th gear works shifting wise. Shifter has some play though.

Engine stalling when depressing brakes dash lights all coming on no cruise control no traction control at oil light check engine light. Dangerous in driving this car. Subaru will not help fix.

6 Power Train problem

Failure Date: 09/01/2020

Changed out the timing belt as part of recommend service by Subaru only to learn that the head gaskets were leaking and it's a known problem with all Subarus built before 2013. Subaru is aware of the problem, and has created a conditioner that is added to the cooling system as a "band aid. ".

8 Power Train problem

Failure Date: 11/29/2019

My vehicle began to have trouble stalling when I slowed slowed down because the rpms dropped far too low. I was not able to stop properly without threat of stalling. My vehicle has now stalled more than 5 times while on the roads and highways. I feel that my safety is thoroughly at stake when my car suddenly turns off. I am very dissatisfied with the lack of cooperation that Subaru has to given to compensate me. If stalling out was not enough, my car has now begun to squeal and buck during acceleration. I was on vacation when this issue became worse and could barely make it back home for work on Monday. In my research I have found that this is a common problem with legacies & outbacks from the years 2010-2012. I find unethical that all Subaru will do is offer an extended warranty that does not cover me.

When slowing down and making a turn the car shuts off forcing me to put it in park and start it up again while almost being hit by traffic. When coming to a stop also it makes it harder to stop because the engine is trying to keep the car moving. This has happed multiple times and still is.

10 Power Train problem

Failure Date: 02/05/2019

Very routinely when coming to a stop from the car moving when you decrease your speed when stopping for a light, traffic, or anything that would require a quick stop, the car will stall out as your speed is less than 10-20 mph and you loose control of the steering, brakes. Ect. This is a huge safety issue and needs to be addressed by Subaru immediately. This can occur on any street, highway and will do this while turning as well. This happens daily in my commute and is a danger to myself and others. It occurs when coming to a stop from a moving position.

When car is coming up to a stop sign it stalls and dies on me and I have to put it in park and start it back up. I had a time where it idled like it was going to die and didn't but it does this 4 to 8 times a day. Not sure what is going on but I almost got hit by a semi truck due to it stalling.

While driving on a road my car will loose power, attempt to stall, rpm's decrease during hard braking situations.

13 Power Train problem

Failure Date: 11/07/2016

** this has happened numerous times, it is not a one-time event. ** while driving and then applying the brakes to try to stop the car, the engine shudders and then stalls out completely - the engine stops. This happens regularly while braking suddenly to come to a stop, and it seems to be avoidable if the car is brought to a stop very slowly and gradually. The car may stall out when stopping at a stop sign on a local road or when coming to a stop at a traffic light on a street or highway. The car must be shifted into park and then restarted. At times this has created a very dangerous and nervous situation for me and my passengers, as well as other drivers on the road, because it has happened in heavy stop-and-go highway traffic. While momentarily stopped on the highway while trying to restart the car a rear end collision is very likely to happen.

14 Power Train problem

Failure Date: 06/14/2016

When applying the brakes at a slow speed the car will stutter and stall. The dealer said they have heard of this problem with this transmission. They said it is not covered and it will need a new transmission.

Failure Date: 06/10/2016

Vehicle has 77,000 miles and is 5 1/2 years old. Now shuddering and stalling at stops, occurred 4 times in 2 weeks at major highway intersections and presents safety hazard.

16 Power Train problem

Failure Date: 11/01/2011

On two separate occasions, I put the vehicle into drive and removed my foot from the brake, before accelerating; the car rolled forward in a shuttering manor and then lunged forward several feet (4-6 ft). The rpms seemed to drop (500-700 rpm) and then spike (1,200-1,500 rpm) with no acceleration at time of the incident. I immediately applied the brake and stopped for several seconds. I then took my foot off the brake again and the vehicle seemed to run fine. The engine was not cold at the time on occurrence; it had been driven approx. 30 minutes before the incident.

17 Power Train problem

Failure Date: 06/05/2011

Jerky cvt operation since day 1. In slow speed traffic (~20mph) the car had a bucking feeling when gently applying the accelerator pedal. This has been a constant throughout my ownership. Just before this catastrophic failure, the vehicle would suddenly jerk between 20-30mph and rpms would drop by 1,500 under normal acceleration as if an improper up-shift had occurred (though I did not cause this to happen, and the cvt has no "gears"). This would happen on any street, any time of day, any grade of incline/decline, turning or straight. Gillman Subaru north's shop foreman had no idea what to say after experiencing the problem firsthand on a test drive. I worked at the dealer when I purchased the vehicle new, and was constantly dismissed by both the dealer, gillman Subaru north, and by Subaru of America, being told it was just a quirk and to enjoy my new car. Now, after a transmission fluid change that was strongly recommended by gillman Subaru north, the transmission valve body has failed and the dealer wants $1772 to repair. Subaru of America was informed of everything, and refused to consider any other customers' experiences, as they evaluate on a case by case basis only. They refused to goodwill anything whatsoever.

18 Power Train problem

Failure Date: 04/17/2011

2011 Subaru Legacy 2. 5i cvt premium model : at highway cruising speeds of 60+ mph, the vehicle feels "wobbly". The car feels as though it is getting swayed from side to side, even on good road in good conditions. I think it has to do with the awd system. I slow down at times when I sense this as it makes me feel very unsafe. It causes a feeling of loss of control of the vehicle. This happens during normal weather conditions (no excessive winds or cross wind loading). This is noticeable to the passengers as well. The swaying or pitching happens in right as well as left directions. No amount of steering wheel control seems to counter this. Tire pressures are accurate to specifications and the car is brand new to me Feb 5, 2011 and has about 700 miles.

19 Power Train problem

Failure Date: 01/19/2011

Engine speed surges occasionally ( 4 episodes in 6 months) when moving very slowly (parking) and wheel is being turned. Hard braking stops car and engine speed returns to normal.
