Subaru is recalling 228,500 2017-2019  Imprezas and Crosstreks for faulty PCV valves, an issue that could  require total engine replacements. Owners of affected vehicles will have  to take their vehicles to the dealer, where CarComplaints reports that they’ll be inspected to see if the engine needs to be swapped.
If  left unattended, the faulty PCV valves may allow oil to enter the  combustion chamber and burn up. Eventually, bits of the valves  themselves may enter the combustion chamber and cause engine failure.
