Subaru Corp. will recall 51,613 units of its Crosstek, Forester and Ascent vehicles for model year 2019 over a defective ventilation valve.
According to a Dec. 11 notice from the National Highway Traffic Safety Administration, the aluminum positive crankcase ventilation, or PCV, can separate and subsequently allow engine oil and PCV valve components into the combustion chamber.
The defect could result in a loss of power while driving, which could then increase the risk of a crash, the U.S. road safety body said.
Subaru will begin recalling affected vehicles on Jan. 24, 2020. Subaru dealers will inspect and replace the PCV for free and will also offer to replace the short block engine for free if the PCV has already separated and the components can no longer be found.
