Subaru Impreza, Crosstrek valve breakup can kill engine power

NHTSA campaign 19V744000 · Reported 2019-10-17 · Subaru of America, Inc.

high How serious is it? About this label

Serious, because an unexpected loss of power while driving can lead to a crash; the notice does not tell owners to stop driving, but get the valve inspected soon.

What's wrong, in plain English

A small aluminum valve that lets pressure escape from the engine can come apart. The broken pieces can then be pulled into the engine, and the engine can lose power while you are driving. A dealer will look at the valve and replace it if needed. If the valve has already broken and the missing pieces cannot be located, Subaru will replace the entire engine. Everything, including an engine replacement, is free. Repairs have been available since December 2019.
