Have you changed your plugs and air filter lately?

It's the CVT! But before you cry ensure that your battery is fully charged and that you don't have a vacuum leak that's submerging the idle control when in Drive or Reverse. But the classic failure mode of the CVT is engine stalling after braking. Replacement of valve body is about the cost of swapping a used CVT (2k+), so I'd have a serious conversation with Subie in NJ soon!

Note: '12 plugs are iridium-tipped. Likelihood of plugs causing lost idle is nil. Same with clogged air filter, as air requirements at idle are very low. Again, check battery condition and connections (clean em?!)...or even try a new battery, as they last 3-6 winters...before chasing SOA for a new CVT.

yakster- just curious, I have a 2010 Subaru Outback with CVT transmission and over 73,000 miles on my car. I haven't had any issues, just how many miles are on your car and can you please describe in what situations this occurs, does it happen at all stops or just sudden stops. Many years ago, I had an 85 T-Bird with this problem and it turned out to be the harmonic balancer. I don't know, maybe, the SubaruGuru in Boston knows if these cars even have a harmonic balancer, although he sounds pretty confident about the failure of the valve body in the CVT transmission. So, how many miles and do you drive this in the mountains or other strenuous situations? Please advise.

No so rare. Tip 'o the iceberg, Mark.

TheSubaruGuruBoston- that's interesting. A few years ago a mechanical engineer told me that the new CVT transmission were simpler, better designed, and more efficient and durable than conventional automatic transmissions. And, Subaru has decided to change all of their old 5EAT transmissions to the new Lineartonic CVT. It's been six years now since the introduction of the Subaru Legacy and Outback models with CVT. You would think that if this were a major problem, then, Subaru might not have switched from the old to the new transmission? Your thoughts on why they did this?

TheSubaruGuruBoston, have you personally seen a lot of people bringing in their cars to your shop with CVT transmission issues? I understand that, in most cases, the only option is to just replace the entire thing, very expensive! I'm grateful to you for suggesting that I get the fluid exchange. Hopefully, that will reduce the risk of failure in my car. I wonder how many people ignore this. Just because it only says to "inspect " the CVT transmission fluid, doesn't mean that you shouldn't have it changed as routine maintenance.
