The contact's girlfriend owns a 2012 Subaru Outback. The contact stated that the vehicle hesitated while starting. In addition, the contact attempted to jumpstart the vehicle; however, the vehicle failed to start. The check engine warning light was intermittently illuminated. The contact stated that during rainy weather, several unknown warning lights were illuminated. The contact scanned the vehicle with an OBD2 scanner and retrieved DTC codes: P0420 (Catalytic convertor) and P0057 (Ignition System). The vehicle was taken to a local dealer to be diagnosed. The contact was informed that there were failures with the rear brake pads, rotors, PCV valve, valve cover gasket, engine air filter, catalytic converter heat shield; and a cylinder #4 misfire. The DTC codes P0304, and P0420 (Catalytic convertor) were also retrieved. The contact was informed that the catalytic converter needed to be replaced first. The contact stated that several repairs were made prior; however, the failure persisted. Upon further investigation, the contact related the failure to Subaru Service Program Bulletin: WQC-39, WVY-35, WUF-91r, TKC-19R, and the federal safety agency Campaign Number: 20V003000 (Air Bags); however, the VIN was not included. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 97,803.

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 federal safety agency, 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.

Just after 100k mile service, car began to shutter when slowing and then stalls at stops. Eventually after I leave it in neutral for up to 2-20 min it will finally restart. First time it happened it wouldn’t start. I had to push vehicle out of major intersection to avoid being hit then pay to tow it to nearest mechanic. Once there, it restarted and problem couldn’t be replicated nor did it relay any codes. Happened again the next two occasions I drove it so I immediately took it to Subaru dealer using side streets to avoid potential accident. After researching my model/year and symptoms, I found this was a common complaint with 2012 Outback’s and there have been numerous CVT issues. One of these issues is a faulty torque converter that causes stalling and usually appears around 100k mile mark (of course just shy of warranty). In 2017 (prior to owning car) a bulletin was released notifying dealers of issue which led to extension of warranty due to customer complaints. Given this new information, I was not shocked when dealer diagnosed my car as needing a new torque converter. Had I known this was an issue beforehand, I would have requested an inspection when spending thousands for 100k mile maintenance. I even brought vehicle to same Subaru dealer years prior (when it would have still been under warranty) for noise and shaking when accelerating/braking. They said this was normal for box engines and test drove it without any concerns. I can’t believe with the vast complaints on CVT issues that Subaru has not issued a recall. It’s irresponsible, dishonest, and a major safety concern. Consumers have right to be notified if they may be affected or put at risk.

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

When coming to a quick or hard stop, car will rumble then stall out. To confirm that the issue is transmission based I shift the car into neutral then brake quickly and the issue does not arise.

No issues with the car since I bought it new and was dedicated to regular Maintenance. Less than a week after a regular scheduled oil change and driving on the main interstate highway cruising at 65mph, the car just suddenly jerked. I thought I had blown a tire but the Brake light came on and then soon after the engine light came on. I was able to get off the highway but the acceleration decreased to a slow crawl. I had it towed to the nearest Subaru dealership that morning in which they said the issue is that both 1 and 4 are not correctly firing. They checked the spark plugs and checked the injector, but both did not fix the issue. They have now told me that they need to get the engine pistons/valves "machined". They are reaching out to Subaru to see if they can help since there is nothing I could have done to prevented this issue and they are hearing more of this issue occurring in Subaru cars. I'm praying that Subaru will help me with my vehicle but am waiting to hear from the Subaru dealership.

The engine shuts off while driving, especially when switching gears or when braking too hard (such as when traffic ahead suddenly stops). I had the engine shut off while I was making a left turn at an intersection and lost control abilities of the steering wheel.

When driving normally on the road the car begins to flash the following lights in the dash( Engine check, Oil Temp Light, Brakes, ABS, Traction control light, airbag light, passenger airbag light indicator) the car continues to drive normally but I cannot know that for certain when almost every indicator light is flashing, I have had the car inspected at a Subaru dealer 4 times since last year for other repairs in which they indicated a detailed inspection of all components following the repairs( radiator, ABS module, Transmission Maintenance, Differential Maintenance, Brake Fluid flush,), spent roughly 6,000$ in repairs and nothing was ever mentioned about this issue, if an inspection was done how could they not find an electrical error.This has happened twice in 3 months I do not feel safe driving a car that cannot properly indicate what internal issues are happening. The car drives fine and is in good condition however only a battery reset and new battery have been able to halt this issue until it happens again. I hope this can be investigated and looked into getting it repaired.

Coming to a stop, not super hard at a turn light. the engine just died! all the lights started flashing so I put the car in park and tried to not freak out. Turned the key off and tried to restart right away and it didn't work, gave it another minute then it started up again, no light on or flashing what the heck. Like nothing just happened, omg my heart was beating and I was shaken up. They need to fix this! this is very dangerous and nerve racking I'm afraid to drive it now because you don't know when this is happing again or not.

1. Over the past months at different times the dashboard lights all start flashing the check engine cruise control breaks Flash on and off 2. Our safety's at risk because we don't know if the engine is needing repair or if it's an electrical problem or if the car's just gonna stop dead 3. We took the car in and they charged me $1500 for a new fan coil and it's still doing it 4. Yes there were many warning lights it has been happening for the past year and I've taken it in twice and it's still happening and now they're saying they have to replace the engine strap which is another $3000 this is ridiculous
