I bought the extended warranty after my first BRZ died on the 3rd day of ownership at 60 miles. It had the well known
CEL/SL/Idle issue. It was knocking so loud and acted like the engine was gonna jump out from under the hood. I told the dealer that I wanted another car. They obliged and I made an emotional decision to get the warranty.
I usually never buy any kind of extended warranty but ultimately, I had a bit of an epiphany; this is the first generation of a car built by two different manufacturers attempting to combine features\functions of each. That's kind of a recipe for disaster and who knows what kind of issues will pop up 5 years from now and 60,000 miles later.
