Today we are going to teardown a 2ZR-FXE 1.8L 4 cylinder engine from a 2016 Toyota Prius. This is the second generation of this engine and allegedly had all of the common problems "fixed". Well, this engine failed at just 73,000 Miles! I was able to get the VIN from the place that sold the engine and I'm astonished this engine is bad at such low miles. This engine ran all the way through the 2022 Prius.
So what happened to this engine? How does one of these fail so soon?

Why am I doing this? My name is Eric and I own Importapart. A full service auto dismantler. Part of our model includes dismantling blown up, failed and otherwise bad engines to salvage the good parts. We do not rebuild engines, merely supply parts to those who do!
