General Motors has issued a recall for certain examples of the Buick Encore GX crossover equipped with the turbocharged 1.2L LIH three-cylinder engine due to an issue with the positive crankcase ventilation (PCV) system.
The problem: affected vehicles may have a blockage of positive crankcase ventilation passage in the camshaft cover. If a vehicle has this problem, crankcase pressure may progressively increase to the point where it could cause the engine to run roughly and may also lead to engine damage. Vehicles experiencing this issue will produce an illuminated malfunction indicator lamp (or check engine light) on the dash/driver information center.
The hazards: this is a voluntary emission recall, so this problem does not pose a safety risk. However as we mentioned above, this problem could lead to engine damage if left unaddressed.
The fix: dealers will inspect the camshaft cover in affected vehicles and replace it if a blockage is detected in the PCV passage.
Affected components: PCV vacuum, PCV passage.
