One problem related to crankcase (pcv) has been reported for the 2013 Buick Verano. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2013 Buick Verano based on all problems reported for the 2013 Verano.
The pcv orifice that is located inside the intake manifold is known to clog due to a manufacture defect, which then produces high pressure inside the crankcase. The pressure then forces high amounts of oil through the valve cover orifice into the intake breather box. The oil then fills up inside and get into the engine air filter and throttle body. The high amounts of oil being sucked into the intake will leave the engine running with zero oil, thousands of miles before a oil change is due. This would obviously destroy the engine if oil is not added regularly. There is also a high risk of the rear main seal blowing due to the high pressurization of the crankcase. This is a very known defect and without a question, needs to be issued as a recall.
