That will only happen if you modified the CVT system buy adding aftermarket cooler, Tuner, etc. that changes anything from how the CVT system was installed or operates from the factory.When not if your CVT takes a dump you can be rest assured that Subaru will determine that the part you installed is the problem. Then you are stuck paying $8k for a new CVT or are without a working vehicle while you argue with SOA.
My CVT was replaced twice and I had an aftermarket exhaust and BRZ wheels with 1-inch wheel spacers. No issues getting it replaced both times since neither of those caused the the CVT failure. I even got a free 7yr/100k Gold plus warranty out of it. :smile2:
