Hello, we have a 2012 Outback. We have had many cars and really like this one/plan on keeping it! It's currently stalling on braking, which is tedious. I paid £375 for a Subaru gargage in Croydon to tell me we needed a new 9K gearbox. I took it for a second opinion to a gearbox specialist in Erith. He was very thorough and said it was NOT the gearbox. So now I'm working through my own list, trying to find source of problem. Two questions for the forum: 1. Can you recommend a garage in the South East? 2. Any ideas/experience of stop/stalling issues? Many thanks. 

Regarding the possible cause(s), I'd suggest you also post your issue on here, as they have a much wider experience of Subarus and OBs.

Hope you get it sorted.

Yeah the first one just tried to scam you, unless there was some other reason they said it needs a new gearbox.

Could be idle control valve or possibly battery/alternator related, sounds daft, but on our XV when the battery was really low it kept stalling when loaded up by the power steering or dropping to idle.
