Took 2017 Buick Cascada in for repair following whistling noise and stalling while idle. This vehicle only has 42K miles. The mechanic was concerned this could/should be a recall issue due to the low mileage on the vehicle. On Google searches, I found similar issues were reported and GM extended the warranty on Buick Cascadas for different years. Both the 2016 and 2019 had a Global Warranty for PCV issues and Camshaft covers. "GLOBAL SAFETY FIELD INVESTIGATIONS [XXX] URGENT - DISTRIBUTE IMMEDIATELY Date: February 16, 2023 Subject: [XXX]- Special Coverage Camshaft Cover The mechanic stated, "the built-in PCV system has failed causing a vacuum issue within the engine and requires the entire camshaft cover to need replacement." The mechanic was unable to do the repair and suggested the vehicle be taken to a GM dealership. It is scheduled for repair at McElveeen Buick in Summerville, SC in the next couple of days. The check engine warning light is on and the vehicle has stalled while idling in traffic. There is a whistling noise resembling a worn belt noise in the right front of the engine.

I have noticed in a Buick thread that I am not the only one who had a PCV valve go bad on 2017 Buick Cascada. The problem is Buick built this valve into the valve cover, it can not be replaced without replacing the whole aluminum cover. The cover was a small 900.00$ fee, plus another 5-600 for mechanic. Seems to me they have an issue with the PCV valves, since I am not the only one with this problem. PCV valve is an important part to emissions and the car.
