2017 Outback CVT Shudder - Is This Normal or a Problem?

0

David L. · rep 0 · May 22, 3:21 AM · 1 replies · solved · Question

Hey everyone, I've got a 2017 Subaru Outback 2.5i Premium with about 85,000 miles on it. Lately, I've noticed a slight shudder or vibration, especially when accelerating gently from a stop or at lower speeds. It's not constant, but it's definitely noticeable.

I'm a bit worried about the CVT transmission. I've heard mixed things about Subaru CVTs and their long-term reliability. Is this shudder a sign of a bigger problem developing, or is it just a characteristic of these transmissions as they age?

I've kept up with all the regular maintenance, but I haven't had the CVT fluid changed yet. Should I be looking into that, or is there something else I should check? Any advice would be greatly appreciated!
