    A Subaru transmission warranty extension has been issued for 2010-2015 Legacy and Outback, 2012-2015 Impreza, 2013-2015 Crosstrek, 2014-2015 Crosstrek Hybrid, 2014-2015 Forester and 2015 WRX vehicles, all equipped with continuously variable transmissions (CVTs).

What WRX Owners Say About This Generation

Long story short, when the vehicle gets built at the assembly line, they're supposed to paint the flywheel bolt with green paint to show that they torqued it to spec. There was no paint which meant that [the flywheel] was not torqued properly.
