Cheryl Sauer says her 2014 Forester XT was never the same after it came back from a 2016 emissions recall. The engine would surge and stall. So naturally, Subaru must have installed some secret software under the guise of an emissions fix to de-tune the engine in an effort to address a long-running ignition timing issue.
A lawsuit says that the Subaru WRX suffers from sudden engine failure due to piston detonation, a well-known cause of damage to the piston and piston ringlands. The proposed class-action includes all current and former owners or lessees of the 2009-2018 Subaru Impreza WRX and WRX STI.
A new lawsuit accuses Subaru of using a 2016 emissions recall as a cover to secretly update engine software meant to prevent surging and stalling issues. If true, that’s both devious and cunning because ”by calling it an official emissions recall, an owner wouldn't be able to renew their vehicle registration until the recall work was complete.”
After some prodding, Subaru has decided to extend the warranty on their Lineartronic CVT.
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).
