2017 Buick Cascada

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.

THE FRONT COLLISION ALERT DOESN'T WORK AT ALL. IT IS SUPPOSED TO LIGHT UP AND MAKE A SOUND TO WARN THAT YOU ARE APPROACHING ANOTHER CAR TO FAST, IT DOESN'T. THE INDICATOR THAT LIGHTS UP GREEN TO SHOW THAT THERE IS A CAR IN FRONT OF YOU SHOULD TURN AMBER IF YOU GET TO CLOSE, IT DOESN'T. THIS IS AN OPTION THAT I BOUGHT AS A SAFETY DEVICE OR SOMETHING TO ASSIST IN MY SAFE DRIVING. I TOOK IT BACK TO THE DEALER AND THE TECH SAID THAT PER THE GM TECHNICAL DOCUMENT THAT IT WORKED AS IT SHOULD, EVEN THOUGH THE SERVICE ADVISOR AND THE TECH AGREED THAT IT DIDN'T WORK AT ALL. I HAVE A COPY OF THE SERVICE MANUAL DOCUMENT, NUMBER 3819903, AND MINE DOESN'T PERFORM AT ALL LIKE THE DOCUMENT SAYS IT SHOULD. I BOUGHT THIS CAR IN PART BECAUSE OF THE SAFETY FEATURE, AS IT STATES ON THE NEW CAR STICKER.
