“I’m having an issue with my vehicle stalling when I brake and when I come to a stop slowly or on an incline. I haven’t had it tested at a dealership but I have read about the issue among other Subaru owners stating it is possible the torque converter in the CVT and that Subaru isn’t recalling it. I see this as a major safety concern for myself and others on the road due to its stalling out at a stop or on an incline.”

“The CVT Transmission has a known problem where the torque converter causes stalling. This issue is well documented on Subaru forums. I took my vehicle to Subaru about the problem and they said the fix for the stalling is to replace the Torque Converter., It is not yet covered for a recall despite being such a large issue with these vehicles.”

“Three identical instances. 1. Was driving down road came to stop light pushed brakes and car stalled out. 2. Was approaching roundabout pushed brakes to wait for traffic and car stalled out. 3. Was on incline at stop pressing brakes, went to push gas and car stalled out. In each instance the car dies completely. You have to take key out, put back in and turn on the vehicle again.”

“Subaru refuses to do a recall for their CVT transmission issue even though this is a know issue with the 2010-2012 Legacy. The car stalls when coming to a stop. Subaru never informed their owners of an issue and now refuse to pay for any repairs, if this was to become a recall then they would be required to pay for the repairs, and then there would be less unsafe vehicles on the road”
